For those who have issues with slow windows, DO NOT GO TO THE DEALER. Buy a lubricant silicone spray and spray along your window frame , give it 5 min and then put your window up and down a few times and bam brand new fast as hell.
Driver window started happening when cold for 1st use in day of window; only time it happens. No other issues. Had G35 for 10 years and only 10-yr battery went out but that's standard...and life. Other than driver window issue with Q50, no issues in 4 years.
Depending on how bad it is when we have that issue come in most of the time we just clean the track and then spray it with DRY spray lubricant if you don’t use dry spray it will work for a little bit then actually get worse more and more debris will build up (Infiniti technician)
This is such a fact. I have been shopping for a car recently and all of the research always points to expensive repairs including Toyota and Honda models. I'm so over looking for a reliable/cost effective car.
For the belt failure you need to loosen the the a/c compressor and push it back and tighten it that’s why the belts would fail when you do that if you catch it early enough you won’t have to change the belt but if you still hear chirping then replace the belt (I’m an Infiniti tech and I own a 17 Q50s)
i had this issue. 2 infiniti dealers turned me away telling me they couldnt duplicate and they wouldnt warranty the repair just becuase. paid nissan to change the belt and look at it. running fine ever since.
I have a question I have a Q50 I can't figure out why the compressor won't ingag I changed the clutch and pressure switch what else could it be is there more than one persure switch
For those of us w/ just lowering springs, Tein now has an adjustable shock option (in case your factory shocks go you don't have to choose between oem and coilovers).
Bought my '17 Q50 Sport CPO. Purchased the Wrap Policy Elite Warranty through Infiniti. HIGHLY recommend it if you're looking to buy an Infiniti. Covers bumper to bumper for 8 years from date of inception with zero deductible. I have had almost everything this video talked about mechanically done at no charge out of pocket.
@@Skilly713 I don't think so. It was only available on Certified Pre-owned vehicles sold through Infiniti. Could be worth a call though. If not, there are aftermarket warranties that are really good though.
I’m at 86k and my 2014 Q50 is currently at the dealer having the blend door actuator and the radiator/engine coolant fan assembly replaced. $2000 poorer, but this is the most significant thing I’ve had to get done so far.
I personally purchased a universal 10 row single pass fluid cooler from Mishimoto and used -6AN hoses to cool the ATF in my 16' 3.0t Red Sport 400 awd, currently odometer is showing 93,346 miles and it was one of the best mods I've ever done. The cooler does the job perfectly, by matching up the hoses to the oem hoses i don't see much pressure loss or increase of pressure in the valvebody, it's not cooling the ATF too much or not enough. I can beat on here and drive it hard, or be sitting in traffic in the summer and it's working perfectly. I monitor my ATF temps just to be sure. My next upgrade will more than likely be another Mishimoto universal fluid cooler to replace the OEM oil cooler, but I'm monitering oil temps, just to be sure, since the red sport models have a thermostatically controlled oil cooler, guess we'll see in the next month or so.
In my view, your videos need to be required viewing for any Q50 owner. Your videos have saved time and money. Most recently I changed the blend door actuator and I am now ready to change the trunk struts and later serpentine belt. Thank you!
Hey I’m from NC and am an Infiniti tech. Yeah turbo failure and also engine failure is very common on the OLDER VR30, think they fixed it 2018 and afterwards. Mostly an oil starvation issue similar to what the RB motors had from what I’ve heard, very rare issue is having a porous engine block that allows coolant to leak. The blend door motor is a bitch to get too, just a tight space. The slow window issue is most likely a window run needing replacement, easy to do. And as you said lots of valve body’s but I don’t see it as often. Great video as always!!
@@maxziplock possibly yes a smell. Best way to tell is by pressure testing it and lifting the vehicle up. If you see coolant seeping through the block then it’s porous. I’d start by checking all hose connections first tho and seeing if I can find a trail of dried coolant
Thanks for posting on here.. i have a 2018 q50 redsport and i have an oil smell in the car when driving. Not driving hard at all but just oil smell inside the car... i had Infiniti come pick up the car but they could not find anything wrong.. does not use any oil but i have also noticed quite a bit of black oil gunk on the tail pipes.. i have a catch can and check it regularly but want to get ideas on where this oil smell is coming from because its not normal.. Oh im a long time g35, g37 and q50 owner. Its still under warranty and i am in alabama so my closest dealer is 4 hours away... any thoughts on things to keep an eye on? I think its injector or turbo related..
3.7 -Cam and crankshaft sensors -power steering pump -front end links (especially if you have aftermarket rims) -valve body/speed sensor (especially if you have aftermarket rims)
@Speed Culture Studios Thanks for the info! I'm preparing for the valve body. Local Nissan dealer just quoted me ~ $2,500 out the door for replacement. Coming from Audi and BMW, this is a small price to pay. Love my Q50 Sport!
This is a pretty spot on list but I will say the injector/fuel rail issues seems to be more common to those running ethanol blends especially those going up to E85….91,93 guys have been pretty safe from this issue . This a pretty short list compared to bmw,Audi, and Mercedes so your so right on just keeping an eye on things ….great video 💯
one I've experienced on the VQ37 and I've seen others having this issue as well is the plastic coupler for the heater hose. It gets brittle and can leak or full on fail causing coolant to leak every where. I replaced mine with a metal one to avoid this "ticking time bomb".
Happening to me right now. It sucks cause i kept buying coolant just for it to leak back out. Even changed the thermostat and radiator cap. Came down to that damn connector thing.
Yup, my 2017 q50 has a blend door problem on the driver's side. To fix it I have to turn the temp all the way high and then all the way cold. Then it works.
My valve body is beginning to show signs of failure. Luckily. We can upgrade our transmission to a vr30 trans relatively easily. And that’s what I plan to do
can't believe that I just watched this video couple days ago, and today my q50 blend door actuator get failed~ thanks for the info, so I can save the money for bring the car to the dealer.
2015 q50 3.7 sport (motordyne exhaust motordyne Advanced Resonance Tuning Test Pipes k&n cold air intake) Ecutek n dyno tune at around 40k. Haven’t had a single maintenance issue running smooth @110,000 only thing I’ve done for preventative maint is changed rotors brake pads spark plugs and serpentine belt and change the oil every 4,500 miles🤞any recommendations?
Lollll i’m scared asl. You mentioned the valve body which I see A LOT of in the Q50/Q60 group. I’m between that 65k-75k miles. I’m sitting a 77k miles, out of warranty margin. Fingers crossed for my baby. My hood struts also failed… Fell on my head. And the chrome trim on cupholder peeling. I’d like to add one though. The heater hose coupler. The plastic piece inside the hose becomes brittle and fails causing a small coolant leak. If this happens, i recommend the Z1 coolant bleeder port. Way better than a piece of plastic.
My Q50 has the same exact problem, the rear heater hose is leaking a little bit of coolant. I'm scheduled to bring my car into the dealership next week Thursday to replace it. Did you fix yours yourself ???
I just purchased a 3-year old q50 and read they were very reliable. Had 2 g37’s before this and never had a problem. Of course I had to replace the rotors after 10 years but that’s expected. I just hope the q50 lives up to the g37 reputation.
2014 q hybrid. Yup, had several these. My passenger occupant sensor also failed. The mat sensor, not the controller. It’s a simple strain gauge, no moving parts. But it failed. See q50 forum for repair details.
What were your symptoms with the trans? Mines acting funny. Shifting hard and feels like it’s drag in the transmission. Seems like the torque converter is always in play
Love how the most replayed is the part about serpentine belt. For good reason too lmao, he is NOT lying about that shit either, it will shred, just a matter of time. Get a Gate®️ replacement belt, pretty sure they’re cheaper. Back in December 2023 mine shredded while I was driving on the highway, not fun.
I have a 14 Q50 and I have 168,000 miles on it. I’ve had relatively no issues except for the air conditioning, actuator driver side and the hood shocks already went out and also both of my mass flow sensors went out, other than that I still love my car
I have a 15' q50s 3.7 awd and it has 150k miles on it and here is whats broke so far: power steering high pressure line leak, front tie rods, front shocks slowly starting go, steering lock (i just disabled it). That's it asides from maintenance. I track it and drive it spiritedly quite alot. Car is stock tho asides from exhaust. Otherwise it still runs and drives great and transmission running great too
I got a 3.7 2015 q50s. The suspension is trash as fuck , it’s super common to have that issue . Lookin to replace mines . The chrome peeling inside is true . Mines is peeling. Factory rotors are true on my sport , got them resurfaced and once they ruined I’m have to replace them. Transmission is still good at 85k. But he’s right with the common issues. I got a backup 3.7 belt in case it shreds.
I bought my 15' Q50 with 70K at 81K my Valve body failed, When I opened the tranny up the fluid Looked like TAR, Infiniti says tranny is maint free for 100K BS!!! CHANGE YOUR FLUID REGULARLY , I swapped the entire trans from a salvage Car 30K. Good Video!!!! Keep em coming!
My car 2015 q50 AWD has 42k. And it’s showing symptoms of failing what should I do? Would changing the fluid help or do I need a whole new valve body. I’ve seen people swap it out for a 3.0 trans
Dang shoulda watched this before i bought my 2019 q50..., its warranty is till 110k for all mechanical and electrical, yeah i paid a bunch extra, im glad i did...
I bought a 2014 with 1 year warranty left. For that 1st year it was a good daily while warrantied. Within a week or 2 past warranty, that car fell apart on me like it was on a stop-watch. Will never touch Infinity crap again. Acura reliability for the win, every time.
This video is on point I am from Jamaica and I have had some of these issues with my 2015 Q50, most I have fixed * Break Rotator * AC * Noisy Widow When Wet * Shocks * Interior Trim Issues * Deck Lid Struts (trunk) * * * Maybe Valve body Failure trying figure this out. Recently found your videos, they are great.

thank you sir have a 15’ awd limited 3.7 in black with 120k miles 2 tone 19 inch wheels , just bought it. picked it up for 9800 cash its had the differential fluids changed / trans so far and spark plugs. It’ll be a fun project. starting with coolant flush. Pretty fun. Been taking it easy, shifts smooth. Still daily my 400 hp taurus it just feels like a cross over to drive and sits higher and it’s a little more convenient. i don’t like how heavy the pedal is in the q50. My g35 was reliable and I had a g37 for a short time and was missing that VQ. Very happy with the q50’s sound system and interior capabilities. Sounds good on cold start ! Probably going to just replace the rear dif bushing when i go in for rotors here soon. Having a slight strut-pop kinda noise from the rear when I launch, but 5 seconds to 60 and gets great fuel mileage around 75 compared to my taurus.
my car acted up on a downshift and the check engine came on one day. it went into limp mode and stopped shifting past 3rd gear. the valve body went bad on my 2014 3.7 at 90,200 miles
Our Q50 the left driver window started going down slow a month ago. We took it into Infiniti service when we got an oil change and they fixed it no charge, but didn't explain what they did to fix it. Thinking still either it just needed to be lubricated or leaves got stuck down there or dirt buildup not sure.
my 2014 qx50 journey awd was made in Japan, 3.7l , 7spd. they have not been made in Japan in a long while, Mexico is my understanding now, im hoping this fact makes a difference in longevity and reliablity.
Keep the content coming. Your vids come in handy. I have a 2018 q50s and for every part that breaks I will use it as an excuse to upgrade it. 😈 Don’t tell my wife 😂🤫
All of what you stated has happened. Got a turbo replaced, windows squeal, and is slow rolling up. Struts on hood , gone to shit…. Low key I fuckin hate this car. But love it
My valve body went out and had to change my transmission. 2015 Q50s, went out around 79k miles Dealership price New transmission: $9,445.15 (labor and part) Used transmission: $6,568.15 Local mechanic : $3200 with everything included *just for those who wanted to know , those are actually numbers that I was quoted *
The comment that chrome flashing on the dashboard trim will eventually flake reminds me how bad the plastic parts in automobiles was 50 years ago. I had a 1975 Chrysler Cordoba that I purchased new. Pretty soon, and well out of warranty period, which was much shorter back then, the plastic shelf on the top of the dashboard developed a large crack. Later one of the tail light lens assemblies fell off. At least that occurred sitting in the driveway, and I was able to glue it back together. Cars were much simpler back then and thus more reliable but the cosmetic plastic used in those cars was much inferior. I may be somewhat biased now that I am able to keep my cars sheltered in the garage and out of the sun most of the time. These days we are accustomed to drive trains lasting hundreds of thousands of miles with only routine maintenance while the engines and transmissions are much more complex than what we had then.
I bought a 2014 Q50 Hybrid sport which I still have…. I haven’t had a single issue, just regular maintenance and 135,000 miles later….still not even a warning light
I just changed my rear diferential fluid and noticed a stained diferential and the bushing is cracked, dried out. At this point I'm just leaving it alone. Car drives just fine
Thanks, man. Important stuff. Btw, at about 40k miles, my deck-lid struts also failed. I tried aftermarket replacements, but ultimately had to get pricey OEM parts.
Knocking on wood as I type this, but nearly 200k miles on my 2015 Sport Hybrid RWD, and so far the only things I have had repaired were the transmission replaced for a cracked bell housing at 63k miles(they replaced with a different part number, transmission from 2016+ maybe? Happened in March 2019), and I had a rear sway bar replacement when I ran over some debris on the highway and it somehow snapped one end of the sway bar loose without breaking anything else. Both were done under warranty(I had the 8 year unlimited mile bumper to bumper up until a month ago). Do get the slow driver window occasionally, but just hit it with lubricant once or twice a year.
U nailed it with this video! Blend door actuator was about to be replaced on our 17 q50 Signature with 49k miles the other day. Dealer quote was around $518. Please post a video on how to replace that, I would greatly appreciate it. Already replaced belt once & rotors resurfaced too. Dealer couldn’t confirm my suspension concern so, I’ll keep an eye out on that next 😧 Keep up the great work! Thank you 💯 😃
The video he referenced on my channel will get you all set till he commits to doing the replacement himself. The link is in his descriptions and It’s super easy!
Couple honorable mentions: 1 - Driver seat squeak/creak. Thankfully the radio is loud to mask this. The squeaky seat makes me insane. Of course the recommended fix is a new seat. Not happening with an out of warranty car. There are internal memos concerning this complaint but no real solutions to my knowledge. 2 - Wheel speed/ABS sensor failure. This one is fun because it causes a bunch of errors to pop up. When one of these go, the ABS isn't functional, the AWD/traction control goes bye bye and you're back to RWD only. The errors are for AWD System, ABS and Chassis Control. Car still runs and drives fine but without the traction control and my heavy right foot, I'm squealing tires like a 16 year old kid. Getting this fixed in a couple days.
I agree, my 370 has a warped stock rotor. It also just lost the fuel sending unit at 64K. So I am guessing till next month. I ain't working on it until the holiday is over. I need all new rotors and pads, lines. it is a 2010 model, so all the electronics are showing the bad Nissan years. You know which parts the gaijin approved.
@@theglassarrow_ I am going to go with the stop tech calipers and EBC rotors carbon ceramic pads. Metal lines. it is a base model Z so it needs the full gambit.
2014 q50 premiums hybrid all wheel drive 75k around 55k dealer did back suspension subframe. I had extended warranty so didn’t pay or this. Nothing else done bullet proof . Off-course oil filters tires. My wife car she says is too old now 😂 to many miles 🤣🤣. I am on the fence to let it go as a trade in.
Hey Maybe you can help me out. I have the exact same car...im getting a pulsing in the breaks that feels like the abs is kicking in for no reason. happens about 45% of the time i'm coming to a stop. Also getting really sensitive breaking sometimes. most of the time its good but then maybe 15% of the time it comes to an aggressive halt with the slightest touch of the break.....very intermittent. Any thoughts?
@@koreehaye6839 I haven't had that exact problem. However, I recently had body work done on the car, and they replaced the front bumper cover. Since then I've had a number of weird issues that I have to assume are related to the body shop having removed and re-installed electronic parts like the front radar sensor, park sensors, etc. The steering intermittently pulls to the left or right (very obviously, it's not subtle) and yesterday I experienced a strange front-end vibration that felt like a computer-induced vibration to get driver attention. I wasn't braking at the time. The body shop (Caliber Collision) has an entire team that specializes in calibrating electronic systems on modern vehicles; it appears they didn't do a great job on mine. I'll probably end up taking it to Nissan or Infiniti to get the system inspected, because I don't feel confident the body shop people can handle it.
Currently Diagnosing my 15 Q50. Misfire on cylinder 4, Mass Air Flow 1 & 2 Low circuit voltage and random multiple misfires. Changed the plugs and noticed a tad bit of oil on a few so now going to replace the injectors and valve cover gasket. Fun.
I don’t think the steering issue is as prevalent as the issues mentioned. I’ve heard some complains over the last several years, but not near as many as other issues.
I have a Q50a with 155k, and all I have ever done is brakes anti freeze and oil change. As a turbo guy, the problem of turbo failure is using dyno oil. Only use synthetic oil. Turbo failure is high in EVERY turbocharged car. Now my blemd doir is acting up and the tranny valve body. Both of these parts I can get for a little over 1500.00. This is a big bill, but it is a small thing if I can get more mileage before I buy the next vehicle.
@@SpeedCultureStudios yeah, covered under warranty. I had to take it to 2 different dealerships, but I finally won the argument. And of course the turbos are on backorder.
Please share this info bro... i have an 18 redsport also still in warranty. I get a slightly oil smell normal driving.. no oil loss that i can see anywhere...
@@_mathtutor3334 I got a 2018 redsport also my passenger side turbo got replaced under warranty and the tensioner pull with a belt. My driver side turbo sounds like the turbo turbine is rubbing against the housing I took it back to them they said they can't hear the sound and just to keep an eye on the noise.
So same with my q40- I have changed my valve body, my diff is leaking as well. My rotors warped at around 50k miles. My door actuator failed as well 🤣. I have changed all these so I’m not worried anymore
Definitely had the deck lid struts, front & back rotors and A/C actuator go belly up. I've got 65k on my 2015 so I'll start watching for the other things. Great video!!
@@ryanharvey9800 damn sorry to hear that bro, i’m at 125k rn and no major issues other than a radiator going out, suspension on all 4 sides, trunk and hood struts, and my oem battery just went out a few weeks ago, i also have a 2014 but still going strong !
Im just now experiencing issues with my 3.7. I’m at like 75000 miles and I feel it jerking a little bit at times even when I’m going slow and straight. Any update on your car?
Kind of late but I recently had to replace the heater hose connector. Little tiny piece of plastic that is destined to go out. Infiniti says they replace those very often
How much they charge you? It’s an inexpensive fix if you do it alone part is only 10-15 bux. They where charging me a couple hundred like 500-700 on my GTI until I saw many videos on how to do it. It was a bitch getting through all the stuff and firewall and took me an hour or so even though I think it would of been less if I had more experience, but it was well worth it
Thank u so much for the video. I recently bought a Q50 2.0 2015 model and sometimes when I accelerate it seems that the power does not go to the right gear. RPM goes high quickly to 4000-5000 but vehicle does not move fast as it suppose to be. Can u pls tell me what could be the problem?
I had the belt fail it didn’t shred but it was squeaking and I replaced it at 20,000 miles on a 2016 red sport. I now have 47,000 trouble free miles on my Infiniti so far, Minus the belt of course. I change my oil between 3-5k. Change my air filters every other oil change as well. I want this thing to last forever. You definitely left out the shitty run flat tires that come with it ,the Dunlops are terrible. They have terrible grip and they are noisy as any tire I’ve ever had. They are probably as noisy as the all-terrain‘s on my super duty.
Rotors came first for me at 80,000 and I’m worried about the rear differential…damn but the rest is chillin cause I’ve actually modified quite a bit, my struts are not stock and I did this because the car is heavy AF let’s be honest the whole deal with the stock struts is probably because it’s a heavy yacht of a sedan with cheap struts. Also my injectors are not stock did that cause figured they didn’t ratio properly or use the right injectors for a big engine like a 3.7 as most other car companies have as well failed to improve on, and I upgraded my oil pan, got an oil cooler, heat exchange, carbon fiber hood to lessen the weight of the car a bit, upgraded sway bar, and lastly with the rotors I did not use the stock rotors I upgraded those and the break caliper as well.
I'm curious about this transmission failure. Never heard about it before. My sister had Ex35 for 8 years, did 180k miles, no problem with AT. I know that we have AT7, but is it that much worse? How about transmission from 3,0TT, IT is also 7AT, but I heard, that it can handle much more torque. Does it mean, that it doesn't have the same issue as 3.7 ? Are gears the same lenght in 3.0 and 3.7 :-) ? And finally - those doors blends, or how you called them. This a common issues in some french cars. I found, that, while, you change direction of flow, when fan is spinning fast it is more common to have this failure - maybe the same concerns Q50. For now I have 55k miles, and no problems with transmission or air door blend :) Greets from Poland.
@@antsy602 well now that’s not true lol. And it’s a pretty broad statement. The 7spd auto isn’t too bad overall and is actually pretty good in the newer Q. The cvt they use in other vehicles is garbage but that’s just because it’s a cvt. There are a lot of cars out there with poor transmissions with far more issues, I am sure.
Does this seem like a bad car to buy as a new college student? Any opinions please, it has everything I could want in a car and I think it’s worth my time and money. I found a 19’ with 60k miles going for 19k.
Great video 👍 I'm living in New Zealand and I got a q50s Hybrid AWD. In her very hard to find spare parts and now I'm looking buy the front shock absorber. Would you be able to give an online store? Thanks
I have a 2014 hybrid and I was told that the hybrid battery is going out and that cost over $10,000 I'm looking to buy a rebuild one so far the car is running good still with no problems it causes the check engine lights to come on time to time other than that the car has been faithful to me but I'm decided if I want to fix it or sell it 🫢🫣🤞🤞🤞
My valve body just completely failed on me out of the blue. 2015 q50 with 53,000 miles. Thank god I got the extended warranty because that would have been 4,000 dollars out of pocket otherwise
2017 Q50T Literally started hearing the "chirping" sound especially when it's warm or after getting the car washed with undercarriage spray! Everything else mentioned, slow windows, heavy trunk.. hell I think you were talking about my car overall! 🤣 BTW I had to replace my blend door Actuator!
2017 q50 RS here. Got a check engine light a few days back, car ran fine until I noticed revs were hanging on longer around 3k. Took it to Infiniti and unfortunately my valve body is no bueno. I was told that the parts and labor would cost me over 3k but luckily my car has 47k miles on it and that it was still covered under warranty!
Im having tranny issues also, first it was a bad tcm, now im throwing the same code and its in limp mode again, luckily i have 47k also on my 2016 q50 rs so my warranty is close but its still there so im getting it fixed this week
Apparently the alternator is a common failure on rhe 3.7. Mine failed at 73k, the warranty replacement failed in a month and the third replacement is now putting out 18 volts so I'm sure it's dying.

For the belt failure you need to loosen the the a/c compressor and push it back and tighten it that’s why the belts would fail when you do that if you catch it early enough you won’t have to change the belt but if you still hear chirping then replace the belt (I’m an Infiniti tech and I own a 17 Q50s)

I personally purchased a universal 10 row single pass fluid cooler from Mishimoto and used -6AN hoses to cool the ATF in my 16' 3.0t Red Sport 400 awd, currently odometer is showing 93,346 miles and it was one of the best mods I've ever done. The cooler does the job perfectly, by matching up the hoses to the oem hoses i don't see much pressure loss or increase of pressure in the valvebody, it's not cooling the ATF too much or not enough. I can beat on here and drive it hard, or be sitting in traffic in the summer and it's working perfectly. I monitor my ATF temps just to be sure. My next upgrade will more than likely be another Mishimoto universal fluid cooler to replace the OEM oil cooler, but I'm monitering oil temps, just to be sure, since the red sport models have a thermostatically controlled oil cooler, guess we'll see in the next month or so.
IS it still going problem free?
In my view, your videos need to be required viewing for any Q50 owner. Your videos have saved time and money. Most recently I changed the blend door actuator and I am now ready to change the trunk struts and later serpentine belt. Thank you!
I appreciate that, Frank. I try to bring as much value as possible as I go through some of these things myself. I'm glad you've found them useful!
Hey I’m from NC and am an Infiniti tech. Yeah turbo failure and also engine failure is very common on the OLDER VR30, think they fixed it 2018 and afterwards. Mostly an oil starvation issue similar to what the RB motors had from what I’ve heard, very rare issue is having a porous engine block that allows coolant to leak.
The blend door motor is a bitch to get too, just a tight space.
The slow window issue is most likely a window run needing replacement, easy to do.
And as you said lots of valve body’s but I don’t see it as often. Great video as always!!
Thanks for the input!!
@@maxziplock possibly yes a smell. Best way to tell is by pressure testing it and lifting the vehicle up. If you see coolant seeping through the block then it’s porous. I’d start by checking all hose connections first tho and seeing if I can find a trail of dried coolant
Thanks for posting on here.. i have a 2018 q50 redsport and i have an oil smell in the car when driving. Not driving hard at all but just oil smell inside the car... i had Infiniti come pick up the car but they could not find anything wrong.. does not use any oil but i have also noticed quite a bit of black oil gunk on the tail pipes.. i have a catch can and check it regularly but want to get ideas on where this oil smell is coming from because its not normal.. Oh im a long time g35, g37 and q50 owner. Its still under warranty and i am in alabama so my closest dealer is 4 hours away... any thoughts on things to keep an eye on? I think its injector or turbo related..
@@_mathtutor3334 if it’s a vr30 chances are probably turbos
slow window .. how is that fixed ? i am having that issue on driver side

-Cam and crankshaft sensors
-power steering pump
-front end links (especially if you have aftermarket rims)
-valve body/speed sensor (especially if you have aftermarket rims)
I got hit with the valve body 🤦♂️ $1,500. The dealer gave me good warranty doing it with them.
Power steering pump 🙋🏽♂️
What's the relationship to the valve body/speed sensor and aftermarket wheels?
@@Chris-ww9uo different size. Creates different outpit
@@tristanoliver2911 oh ok your referring more to different over all diameters.
@Speed Culture Studios Thanks for the info! I'm preparing for the valve body. Local Nissan dealer just quoted me ~ $2,500 out the door for replacement. Coming from Audi and BMW, this is a small price to pay. Love my Q50 Sport!
Is there anything preventative you can do for this?
This is a pretty spot on list but I will say the injector/fuel rail issues seems to be more common to those running ethanol blends especially those going up to E85….91,93 guys have been pretty safe from this issue . This a pretty short list compared to bmw,Audi, and Mercedes so your so right on just keeping an eye on things ….great video 💯
Your statement about the German manufacturers is 100% correct lol
one I've experienced on the VQ37 and I've seen others having this issue as well is the plastic coupler for the heater hose. It gets brittle and can leak or full on fail causing coolant to leak every where. I replaced mine with a metal one to avoid this "ticking time bomb".
Happened to me 3 weeks ago
You have a link for a good metal one?
@@Trent_Moorman look up “Dorman - Help Heater Hose Connectors - 3/4 In. X 3/4 In. Connector - Metal” on advance auto part.
Happening to me right now. It sucks cause i kept buying coolant just for it to leak back out. Even changed the thermostat and radiator cap. Came down to that damn connector thing.
@@The_sTress yea is a common issue but no worries you’ll be good man once changed
I was trying to figure out why my A/C was doing that, glad you listed that actuator in this video I can finally fix the problem.
Yup, my 2017 q50 has a blend door problem on the driver's side. To fix it I have to turn the temp all the way high and then all the way cold. Then it works.
I will try that , thanks
Im a 2018 q50'er, 3 sensors out so far, cam shaft sensor (lower right), speed sensor and windshield fluid sensor. 125k miles.
My valve body is beginning to show signs of failure. Luckily. We can upgrade our transmission to a vr30 trans relatively easily. And that’s what I plan to do
Might as well right!
What year is your Q ? And how much would the upgrade be? Thank you
Every single one of these I’ve had to get replaced except rear diff but maybe I need to check that too 😂
Hit you hard 😂
can't believe that I just watched this video couple days ago, and today my q50 blend door actuator get failed~ thanks for the info, so I can save the money for bring the car to the dealer.
Mine is out now too!
2015 q50 3.7 sport (motordyne exhaust motordyne Advanced Resonance Tuning Test Pipes k&n cold air intake) Ecutek n dyno tune at around 40k. Haven’t had a single maintenance issue running smooth @110,000 only thing I’ve done for preventative maint is changed rotors brake pads spark plugs and serpentine belt and change the oil every 4,500 miles🤞any recommendations?
Lollll i’m scared asl. You mentioned the valve body which I see A LOT of in the Q50/Q60 group. I’m between that 65k-75k miles. I’m sitting a 77k miles, out of warranty margin. Fingers crossed for my baby. My hood struts also failed… Fell on my head. And the chrome trim on cupholder peeling.
I’d like to add one though. The heater hose coupler. The plastic piece inside the hose becomes brittle and fails causing a small coolant leak. If this happens, i recommend the Z1 coolant bleeder port. Way better than a piece of plastic.
Good addition
My Q50 has the same exact problem, the rear heater hose is leaking a little bit of coolant. I'm scheduled to bring my car into the dealership next week Thursday to replace it. Did you fix yours yourself ???
Valve body failed at 71k on my 370z.. sad lyfe
I just purchased a 3-year old q50 and read they were very reliable. Had 2 g37’s before this and never had a problem. Of course I had to replace the rotors after 10 years but that’s expected. I just hope the q50 lives up to the g37 reputation.
They are great cars!
2014 q hybrid. Yup, had several these. My passenger occupant sensor also failed. The mat sensor, not the controller. It’s a simple strain gauge, no moving parts. But it failed. See q50 forum for repair details.
wow my old q50 3,7 had the trans value body and ac blend actuator go out within the first 2 months but luckily the warranty covered both
What were your symptoms with the trans? Mines acting funny. Shifting hard and feels like it’s drag in the transmission. Seems like the torque converter is always in play
Love how the most replayed is the part about serpentine belt. For good reason too lmao, he is NOT lying about that shit either, it will shred, just a matter of time. Get a Gate®️ replacement belt, pretty sure they’re cheaper. Back in December 2023 mine shredded while I was driving on the highway, not fun.
I have a 14 Q50 and I have 168,000 miles on it. I’ve had relatively no issues except for the air conditioning, actuator driver side and the hood shocks already went out and also both of my mass flow sensors went out, other than that I still love my car
I put a set of Drilled Rotors on my QX50 man made a big difference
It’s a good upgrade!
I have a 2010 Altima with the slow window issue. 12 years and 200k miles later, they haven't stopped but they're still slow.
Lol, as long as they’re still working!
They must have fixed most of them. Only problem I have had in a 125k is the ac Actuator and brake rotors
I have a 15' q50s 3.7 awd and it has 150k miles on it and here is whats broke so far: power steering high pressure line leak, front tie rods, front shocks slowly starting go, steering lock (i just disabled it). That's it asides from maintenance. I track it and drive it spiritedly quite alot. Car is stock tho asides from exhaust. Otherwise it still runs and drives great and transmission running great too
Very good!
I got a 3.7 2015 q50s.
The suspension is trash as fuck , it’s super common to have that issue . Lookin to replace mines .
The chrome peeling inside is true . Mines is peeling.
Factory rotors are true on my sport , got them resurfaced and once they ruined I’m have to replace them.
Transmission is still good at 85k.
But he’s right with the common issues. I got a backup 3.7 belt in case it shreds.
I bought my 15' Q50 with 70K at 81K my Valve body failed, When I opened the tranny up the fluid Looked like TAR, Infiniti says tranny is maint free for 100K BS!!! CHANGE YOUR FLUID REGULARLY , I swapped the entire trans from a salvage Car 30K. Good Video!!!! Keep em coming!
My car 2015 q50 AWD has 42k. And it’s showing symptoms of failing what should I do? Would changing the fluid help or do I need a whole new valve body. I’ve seen people swap it out for a 3.0 trans
Dang shoulda watched this before i bought my 2019 q50..., its warranty is till 110k for all mechanical and electrical, yeah i paid a bunch extra, im glad i did...
My valve body just went out all of a sudden yesterday... Was leaving the supermarket and got some really hard shifts and now it's stuck in 1st gear
I bought a 2014 with 1 year warranty left. For that 1st year it was a good daily while warrantied. Within a week or 2 past warranty, that car fell apart on me like it was on a stop-watch. Will never touch Infinity crap again. Acura reliability for the win, every time.
This video is on point I am from Jamaica and I have had some of these issues with my 2015 Q50, most I have fixed
* Break Rotator
* AC
* Noisy Widow When Wet
* Shocks
* Interior Trim Issues
* Deck Lid Struts (trunk)
* * * Maybe Valve body Failure trying figure this out.

thank you sir have a 15’ awd limited 3.7 in black with 120k miles 2 tone 19 inch wheels , just bought it. picked it up for 9800 cash its had the differential fluids changed / trans so far and spark plugs. It’ll be a fun project. starting with coolant flush. Pretty fun. Been taking it easy, shifts smooth. Still daily my 400 hp taurus it just feels like a cross over to drive and sits higher and it’s a little more convenient. i don’t like how heavy the pedal is in the q50. My g35 was reliable and I had a g37 for a short time and was missing that VQ. Very happy with the q50’s sound system and interior capabilities. Sounds good on cold start ! Probably going to just replace the rear dif bushing when i go in for rotors here soon. Having a slight strut-pop kinda noise from the rear when I launch, but 5 seconds to 60 and gets great fuel mileage around 75 compared to my taurus.
Rear abs sensors I see pretty common also. I’m nearing 70k and so far so good with the trans, keeping my fingers crossed haha
I’m with ya!

Our Q50 the left driver window started going down slow a month ago. We took it into Infiniti service when we got an oil change and they fixed it no charge, but didn't explain what they did to fix it. Thinking still either it just needed to be lubricated or leaves got stuck down there or dirt buildup not sure.
Very true..... just don't go to the dealership for parts...... please, it's getting up there with Merc parts.... 🤯🤦♂️
my 2014 qx50 journey awd was made in Japan, 3.7l , 7spd. they have not been made in Japan in a long while, Mexico is my understanding now, im hoping this fact makes a difference in longevity and reliablity.

The comment that chrome flashing on the dashboard trim will eventually flake reminds me how bad the plastic parts in automobiles was 50 years ago. I had a 1975 Chrysler Cordoba that I purchased new. Pretty soon, and well out of warranty period, which was much shorter back then, the plastic shelf on the top of the dashboard developed a large crack. Later one of the tail light lens assemblies fell off. At least that occurred sitting in the driveway, and I was able to glue it back together. Cars were much simpler back then and thus more reliable but the cosmetic plastic used in those cars was much inferior. I may be somewhat biased now that I am able to keep my cars sheltered in the garage and out of the sun most of the time. These days we are accustomed to drive trains lasting hundreds of thousands of miles with only routine maintenance while the engines and transmissions are much more complex than what we had then.
great perspective!
I bought a 2014 Q50 Hybrid sport which I still have…. I haven’t had a single issue, just regular maintenance and 135,000 miles later….still not even a warning light
I just changed my rear diferential fluid and noticed a stained diferential and the bushing is cracked, dried out. At this point I'm just leaving it alone. Car drives just fine
Thanks, man. Important stuff. Btw, at about 40k miles, my deck-lid struts also failed. I tried aftermarket replacements, but ultimately had to get pricey OEM parts.
One of the first things I had to replace!
Knocking on wood as I type this, but nearly 200k miles on my 2015 Sport Hybrid RWD, and so far the only things I have had repaired were the transmission replaced for a cracked bell housing at 63k miles(they replaced with a different part number, transmission from 2016+ maybe? Happened in March 2019), and I had a rear sway bar replacement when I ran over some debris on the highway and it somehow snapped one end of the sway bar loose without breaking anything else. Both were done under warranty(I had the 8 year unlimited mile bumper to bumper up until a month ago).
Do get the slow driver window occasionally, but just hit it with lubricant once or twice a year.
Great run!
1. Definitely true I have a Q50S and just ordered some drilled and slotted rotors because of the vibration from the factory rotors.
Yea bro same problem here
what was costs??
Thanks for this video! Have you needed to replace the transmission valve body yet? How much would that typically cost?
No I haven’t. It’s quite expensive and doesn’t necessarily mean it won’t happen again. Many people are simply upgrading to the vr30 trans
U nailed it with this video! Blend door actuator was about to be replaced on our 17 q50 Signature with 49k miles the other day. Dealer quote was around $518. Please post a video on how to replace that, I would greatly appreciate it. Already replaced belt once & rotors resurfaced too. Dealer couldn’t confirm my suspension concern so, I’ll keep an eye out on that next 😧
Keep up the great work! Thank you 💯 😃
The video he referenced on my channel will get you all set till he commits to doing the replacement himself. The link is in his descriptions and It’s super easy!
Couple honorable mentions: 1 - Driver seat squeak/creak. Thankfully the radio is loud to mask this. The squeaky seat makes me insane. Of course the recommended fix is a new seat. Not happening with an out of warranty car. There are internal memos concerning this complaint but no real solutions to my knowledge. 2 - Wheel speed/ABS sensor failure. This one is fun because it causes a bunch of errors to pop up. When one of these go, the ABS isn't functional, the AWD/traction control goes bye bye and you're back to RWD only. The errors are for AWD System, ABS and Chassis Control. Car still runs and drives fine but without the traction control and my heavy right foot, I'm squealing tires like a 16 year old kid. Getting this fixed in a couple days.
@ 91,000 miles on my 3.7 I'm receiving abs warnings and AWD high temp warnings. Apparently bad speed sensors are common with this platform as well.
@zolotovasoulmate7807my g35 kept doing that
i have a q50 base model. had the rotor problem also.
I agree, my 370 has a warped stock rotor. It also just lost the fuel sending unit at 64K. So I am guessing till next month. I ain't working on it until the holiday is over. I need all new rotors and pads, lines. it is a 2010 model, so all the electronics are showing the bad Nissan years. You know which parts the gaijin approved.

My rear struts were done by 30k miles, replaced them with new ones but preferred the broken ones because it was much easier to close.
Hey Maybe you can help me out. I have the exact same car...im getting a pulsing in the breaks that feels like the abs is kicking in for no reason. happens about 45% of the time i'm coming to a stop. Also getting really sensitive breaking sometimes. most of the time its good but then maybe 15% of the time it comes to an aggressive halt with the slightest touch of the break.....very intermittent. Any thoughts?
@@koreehaye6839 I haven't had that exact problem. However, I recently had body work done on the car, and they replaced the front bumper cover. Since then I've had a number of weird issues that I have to assume are related to the body shop having removed and re-installed electronic parts like the front radar sensor, park sensors, etc. The steering intermittently pulls to the left or right (very obviously, it's not subtle) and yesterday I experienced a strange front-end vibration that felt like a computer-induced vibration to get driver attention. I wasn't braking at the time.
The body shop (Caliber Collision) has an entire team that specializes in calibrating electronic systems on modern vehicles; it appears they didn't do a great job on mine. I'll probably end up taking it to Nissan or Infiniti to get the system inspected, because I don't feel confident the body shop people can handle it.
Currently Diagnosing my 15 Q50. Misfire on cylinder 4, Mass Air Flow 1 & 2 Low circuit voltage and random multiple misfires. Changed the plugs and noticed a tad bit of oil on a few so now going to replace the injectors and valve cover gasket. Fun.
I'm having multiple misfires on cylinder 1, replaced the plugs. Running ok at the moment
Surprised the Steering rack wasn’t mentioned but overall very good information to note.
I don’t think the steering issue is as prevalent as the issues mentioned. I’ve heard some complains over the last several years, but not near as many as other issues.

2017 Q50S 113.000 km and only fluids and brake replacement ;)
I have a Q50a with 155k, and all I have ever done is brakes anti freeze and oil change.
As a turbo guy, the problem of turbo failure is using dyno oil. Only use synthetic oil. Turbo failure is high in EVERY turbocharged car.
Now my blemd doir is acting up and the tranny valve body. Both of these parts I can get for a little over 1500.00. This is a big bill, but it is a small thing if I can get more mileage before I buy the next vehicle.

Kind of late but I recently had to replace the heater hose connector. Little tiny piece of plastic that is destined to go out. Infiniti says they replace those very often
How much they charge you? It’s an inexpensive fix if you do it alone part is only 10-15 bux. They where charging me a couple hundred like 500-700 on my GTI until I saw many videos on how to do it. It was a bitch getting through all the stuff and firewall and took me an hour or so even though I think it would of been less if I had more experience, but it was well worth it
Thank u so much for the video. I recently bought a Q50 2.0 2015 model and sometimes when I accelerate it seems that the power does not go to the right gear. RPM goes high quickly to 4000-5000 but vehicle does not move fast as it suppose to be. Can u pls tell me what could be the problem?
Sounds like the valve body issue mentioned in this video
I had the belt fail it didn’t shred but it was squeaking and I replaced it at 20,000 miles on a 2016 red sport. I now have 47,000 trouble free miles on my Infiniti so far, Minus the belt of course. I change my oil between 3-5k. Change my air filters every other oil change as well. I want this thing to last forever. You definitely left out the shitty run flat tires that come with it ,the Dunlops are terrible. They have terrible grip and they are noisy as any tire I’ve ever had. They are probably as noisy as the all-terrain‘s on my super duty.
Well, the run flats won't necessarily "fail" so I wouldn't include them, but they do suck! As do all run flats for the most part.
What did you replace then with?
Yah my 3.7 2015 q50 my trans blew everything u said I pretty much I encountered But I just can’t let go I love my car
They are great cars!
Rotors came first for me at 80,000 and I’m worried about the rear differential…damn but the rest is chillin cause I’ve actually modified quite a bit, my struts are not stock and I did this because the car is heavy AF let’s be honest the whole deal with the stock struts is probably because it’s a heavy yacht of a sedan with cheap struts. Also my injectors are not stock did that cause figured they didn’t ratio properly or use the right injectors for a big engine like a 3.7 as most other car companies have as well failed to improve on, and I upgraded my oil pan, got an oil cooler, heat exchange, carbon fiber hood to lessen the weight of the car a bit, upgraded sway bar, and lastly with the rotors I did not use the stock rotors I upgraded those and the break caliper as well.
Sounds like you have a nice platform you're working with. It's a solid car over all. Just like any car, they are bound to have their quirks.
Listen to him the belt is highly recommended and rotors just all the way right
I'm curious about this transmission failure. Never heard about it before. My sister had Ex35 for 8 years, did 180k miles, no problem with AT. I know that we have AT7, but is it that much worse?
How about transmission from 3,0TT, IT is also 7AT, but I heard, that it can handle much more torque. Does it mean, that it doesn't have the same issue as 3.7 ?
Are gears the same lenght in 3.0 and 3.7 :-) ?
And finally - those doors blends, or how you called them. This a common issues in some french cars. I found, that, while, you change direction of flow, when fan is spinning fast it is more common to have this failure - maybe the same concerns Q50. For now I have 55k miles, and no problems with transmission or air door blend :)
Greets from Poland.
It’s a very common problem in the 2014-2015 q50.
Thank you for the comment and for watching!!
Nissan has the worst transmission, almost hands down.
@@antsy602 well now that’s not true lol. And it’s a pretty broad statement. The 7spd auto isn’t too bad overall and is actually pretty good in the newer Q. The cvt they use in other vehicles is garbage but that’s just because it’s a cvt. There are a lot of cars out there with poor transmissions with far more issues, I am sure.
@@SpeedCultureStudios My bad... Yes, the CVT transmission is exactly what I'm referring to. Trash...
Does this seem like a bad car to buy as a new college student? Any opinions please, it has everything I could want in a car and I think it’s worth my time and money. I found a 19’ with 60k miles going for 19k.
If you stay on top of maintenance and you can afford the 19k while in college, then it should treat you well.

I’m sure it’s the same subframe used, unfortunately
I just got a 2019 red sport with 17k miles but after watching this video I feel like going back to my accord
lol you should be fine if you keep up with maintenance! And that car has a ton of potential!
Rear wheel speed sensors. Also any updates on diff bushing???
No updates yet on the bushing that I have heard-other than “soon.”
Great video 👍
I'm living in New Zealand and I got a q50s Hybrid AWD. In her very hard to find spare parts and now I'm looking buy the front shock absorber. Would you be able to give an online store?
Thanks
Thank you for watching! I'm not sure of sites that ship international, but you could try infinitipartsdeal.com or check out moog's website.
@@SpeedCultureStudios thank you so much, I'll try....👍
I have a 2014 hybrid and I was told that the hybrid battery is going out and that cost over $10,000 I'm looking to buy a rebuild one so far the car is running good still with no problems it causes the check engine lights to come on time to time other than that the car has been faithful to me but I'm decided if I want to fix it or sell it 🫢🫣🤞🤞🤞
Hmmm....70000 miles and no issues you listed
Nice! Check your diff bushing though-chances are pretty good it’s done
My valve body just completely failed on me out of the blue. 2015 q50 with 53,000 miles. Thank god I got the extended warranty because that would have been 4,000 dollars out of pocket otherwise
New subbie when you said ac cold on one side... I'm experiencing that now!!! I'm waiting to see if you mention speed sensor...
I’ve heard a couple people mention speed sensor lately!
Hey when you mentioned fuel injector failure for the 3.0t do you know if same thing goes for the 3.7?
No known issues with injector failure on the 3.7
@@SpeedCultureStudios cool 👍
I also suspect my valve body. First to second is rough until the trans warms up, and sometimes revs flare in a shift.
Yea mine went out dealer want like 2200 for a valve body lol
@@Gtyoungin21 same here, infiniti Q40 3.7, valve body had to be replaced because the acceleration was jerky.
2017 Q50T
Literally started hearing the "chirping" sound especially when it's warm or after getting the car washed with undercarriage spray! Everything else mentioned, slow windows, heavy trunk.. hell I think you were talking about my car overall! 🤣 BTW I had to replace my blend door Actuator!
lol such common things!
Where did you get that camera that showed underneath the car? Also what is it called ?
It’s a GoPro mounted to the underside
2017 q50 RS here. Got a check engine light a few days back, car ran fine until I noticed revs were hanging on longer around 3k. Took it to Infiniti and unfortunately my valve body is no bueno. I was told that the parts and labor would cost me over 3k but luckily my car has 47k miles on it and that it was still covered under warranty!
Dang! Don’t hear about valve body issues much with the vr30 trans.
@@SpeedCultureStudios happened out of the blue! Just a normal commute to work one morning and the check engine light nonchalantly popped up...
Im having tranny issues also, first it was a bad tcm, now im throwing the same code and its in limp mode again, luckily i have 47k also on my 2016 q50 rs so my warranty is close but its still there so im getting it fixed this week
My shifts are a bit boggy while going slow around 1-2.5k rpm’s I wonder if my trans is starting to fail.. 2016 rs
Has most of these issues been fixed by the 2020 model??
Apparently the alternator is a common failure on rhe 3.7. Mine failed at 73k, the warranty replacement failed in a month and the third replacement is now putting out 18 volts so I'm sure it's dying.
That's strange. I hadn't heard that. I did replace the battery at about 50k miles, but no alternator issues.
@@SpeedCultureStudios the dealer said with the design of the grill, they were bad to get debris or rain on them while you drove.
Hello sir! how do you feel about the rear mounted turbo kit made for the q50 3.7? Worth it?
It’s awesome!
Where do you get that?
Did the Rear dif bushing come out yet?
Yes. It’s been out awhile. Check out my install video!
