Авто/Мото
I sold my 2018 with 26,000 when I started to notice some vibrations. The cadillac dealers told me it was nothing. I decided it was too stressful and reading all the issues and watching all the videos showing all the Escalade issues I just took the loss and moved on. It's a real shame because it's a beautiful truck. Every now and then I think I want another one and then I come across a video like this one and I reinforces the fact that GM can't be trusted. I want a reliable vehicle if it's gorgeous that's icing on the cake, but the Cadillac Escalade is not reliable. Check out how many are always available for sale even with low mileage, that should give you the answer. If they are so great why are people dumping them under 30,000 miles? Lifter failures and transmission issues are common amongst other things. Lack of response from GM and Cadillac dealers are another huge issue.
Have you found any competent contemporaries? i refuse to get the ugly ass Navigator of the same year. I was HEAVILY considering it because it fits all my needs of what i require in a rideshare/transportation vehicle but nevermind i'll take a hard pass hahaha
@@michaelwalker8870I’m in the same boat as you buddy. One of my 2017s has a knock issue in the first few shifts of the day between the 1st and 2nd gears. On forums, it says the recommend fix is adding Lubegard Platinum and Shudderfix but I doubt that’ll solve the root problem. As for the navigators, well they look like Honda Odysseys from the back. Your best bet from the 4th gen Escalade are the 2018-2020 models. The 5th gen (2021+) look ugly in my opinion.
@@michaelwalker8870just buy a sequioa and you'll have peace in your life
@@invisisense5464 friend, were you able to solve the problem with the lubegard platinum fluid, I have the same problem with my 2016 cadillac escalade, it has 56,000 miles and it has sudden shifts, please let me know.
@@monchoalamillo9404 Haven’t tried it yet so far, cars at 122K and I have the get it done soon. When I do it I will update you. By the way I read in forums online that said that it worked. It takes somewhere around a month for the lubegard to take full effect. Read on forums to check the exact process. I also believe another way of fixing the issue is to go to GM and get them to change the ATF, as they changed it in 2019: this solved the problem for a lot of people.
Oh crap. Just bought a ‘16 ESV platinum. No shudder on test drive. On my drive home from dealer, crazy shudder. Took it back to get tranny flushed. Runs like new now.😊
I have the same issue with my 2015 Escalade. Also broke my engine mounts which is also an expensive fix. Started around 25,000 miles. Have 105,000 miles now. Took it in 5 times under warranty and the dealer tried all the “fixes” but nothing worked. As soon as the warranty expired, the dealer said I need a new transmission.
I would have got rid of it right before the warranty expired
I had all these problems less than 30k miles. Unfortunately it has no warranty because it’s 2017. I had the transmission issue started when it was under warranty but the dealership said it doesn’t have any fault code and they keep my vehicle there for 2 weeks and I had to take it back. I should have bought a Lexus or any other Japenes car. I will never buy any America car ever again. I have 2010 Acura MDX with 150k miles still runs like brand new
torque converter from 2015 to the middle of 2018 8 speed trans have a problem. This is the reason of vibration when driving at a certain speed.
As for that kick when you stop..
Transmission oil must change every 50k mile.
As for me they change the torque converter with a modified one from the factory free of defects.
As for the kick clean throttle body and add catch oil can... Keep it clean always.
No one should have to worry about all this hassle for what these cars cost. But thank you for heads up.
Is using ATF lubes like Lubegard Platinum going to solve the issue? Or do I have to do something about the torque converter?
Excellent honest feedback! Thank you!
I had a 20016 Yukon Denali with the same problems. I just traded it in for a 2019 Escalade with the 10 speed transmission no problems so far
I got a 2015 but mine has the old 6speed. I love it. I know they're bullet proof. I put 240k miles on my yukon xl denali with the same transmission so it should hold up
How do you know you have the old transmission?
@@edwardcm9175 the 2015s with the og cadillac symbol have the 6speeds in them. They don't have a low range on the selector switch
I had a 2017 and it was a nightmare. Got rid of it and bought a 2020. I have 100K miles on my 2020 with zero issues.
I just picked up a 2024 esv. Shudder problems at low speed. I just dropped at dealer today. 😭
I think if you do a transmission software programming it will solve the issue. One of the solutions I got a feedback from people GM owners they fixed the issue through transmission programming. You only need to find a good professional guy who can do it for you
Had a 2016 Camaro SS with the 8 speed auto. New torque converter at 10 k because of the shutter. Traded it in on another 16 SS when I felt the shutter come back one time. This one with the 6 speed manual. Never had transmission problems again.
Wow!!! I brought mines used with57000 on it. It’s doing everything that is mentioned. Didn’t know about the 47000 miles transmission oil change; getting it done tomorrow…$400…smdh! Also, when I take it though the car wash with the underwash, the check engine light comes on.
My 2015 Denali is at 107k… The only major issue I have to do is replace the fuel injector. Every since then I have no big major problems so far. Love it ❤. Will see how long it’ll last. 🤞🤞🤞
What where you're symptoms with the full injectors?
@@johnmcclindon2657 my injector were clogged n dirty. It’s only one, but I replaced three of them. Still have no issues since. 😀
I agree with everything your saying I am 2016 same issues I have check engine light on even GM can’t fix it one problem fix there is another one as much as I love this vehicle I hate it
My 16' Escalade started with the shudder last September at about a 100,000 miles, a friend of mine who works at a Chevy dealership did the triple flush which instantly fixed the shudder but there was some slippage between 3rd and 5th, which he said it would take a little while for the new fluid to work through the tranny. After about a month 90% of the slippage was gone, after a couple months I didn't notice any slippage at all until this spring, which started almost immediately after having him change the fuel injectors and the slippage was worse than ever. Took it to a transmission shop who said they didn't feel any issues when they drove it (which I could believe because its non stop) but did another flush and said it was all set, which it isn't, it's worse than ever. Don't know if its just sheer coincidence that it started acting up again right after the injector change or if it could somehow have something to do with it, which I can't fathom how it could but it's awful funny after being good for 6 months it started slipping again right after.

I've dealt with every last bit of this with my 2015 Escalade ESV that's now at 150,000. I had a new transmission installed at 113,000 curtesy of General Motors - and yes, my driver's side engine mount is currently broken as well.
Mine went our approximately around 115k miles if I’m not mistaking
I have 194k and the trans shifts good
Yep... It's a shame... I just bought a 2018 GMC Denali with 8l90 trans...brought it back....banged and clunked and shuttered terribly. You spent a lot of money sorry for all your trouble.... GM should own up to this.
I know but they don’t even acknowledge the problem. They say all the issues are fixed with those trans
Have a 2015 escalade, 151627 miles. Hard 1-2, and occasionally when stopping the 2-1 is alittle hard, don't really have much issues with mine, going to keep praying and taking care of it
How long have you had it? I bought my 2015 Yukon XL Denali about a month ago and after a few days it started hard shifting. It's really bad the first few times after driving it without warming it up, although warming it up seems to help a bit. I ended up having a mechanic change out the transmission fluid to the new fluid they recommend by Mobile 1 hoping it would help and it doesn't. When I took it to another shop that deals with only transmissions, he thought it was going to be really bad but when he tested it with his meter, it turns out it's because of a bad transmission fluid temperature sensor. I am honestly going to try to install it myself because the transmission shop wants 900 freakin' dollars. For half that I'm getting the part, a new torque wrench, 2 6-pack cases of fluid, two fluid pumps, 4 heavy-duty jack stacks so I can get it up higher and also level it to get the proper fluid level in the transmission, as well as the wire harness and sensor replacement. Yeah, I'm going to be doing it myself and nervous to do this kind of repair as I've never done it before, but it looks pretty straight forward, and all I have to do is drop the oil pan for the transmission. But so far that seems to be the cause for the hard shifting, so if you have an OBD scanner, or can take it to a shop and have them scan it, they will be able to tell you what the issue is. I hate that I still have to drive the damn thing a few more times before I get all the parts, though.
@ltsallwood do you have the 6speed or 8 speed in your 2015? Any updates after you made this repair? Better? Worse?
I have the 8speed,
In the time frame the Lifters went out had it rebuilt, 7800 bucks
But I only have hard 1-2 during initial start up, once I reach around 120-180 it runs butter smooth, little bit of slip but I'm currently trying at 170k miles
Great video man
This is wild mines is doing the same thing right now 92k miles on it and it seems to happen when when you a little heavy on the rpm’s and let off the peddle to fast
Decided to dump mine what a beautiful suv ..unreal that gm just do it for the money and not realiability
Thankfully this happened while under warranty.
I have a 17 Sierra Denali 6.2. Had shudder back at 20K. Warranty changed the fluid. It ran well until 50K when the shudder came back and was worse. Warranty changed the torque converter. A couple of thousand miles later another issue arose and warranty changed the internal wiring harness. Haven’t had any problems since, other than an rare hard shift from 1 to 2 at low speed.
That hard shifting is gonna get worst and worst until transmission give up
Same problem on my 2017 Escalades 1-2 and 2-1
You just saved me ninety thousand
Had cue screen placed on my 16 esv ,also trans flushed with updated fluid because of shutter , plus ac condenser replaced, all done under drivetrain warranty before I hit 70k miles , man if I was out of drivetrain warranty, these known issues would of cost me big , I feel your pain
What's the updated fluid? I'm about to get my transmission flushed and changed.
@@terryhammer9493 Mobil 1 Synthetic LV ATF HP fluid. , this is the fluid upgrade , if your still under drivetrain warranty, it’s a free change, but outside of warranty, Cadillac charges $600
Just did my AC and reset my screen. Have done multiple Transmission Flushes. All, of course, out of Warranty. I’ve had three Escalades, they all have issues. My last two had the power mirrors quit. No coverage and big money to replace. Maybe time for a Benz!
Our shop had a 2018 Z71 with the same problem. They had a new transmission installed and traded the truck in a year later
Thank you for your video
Needs to be a lawsuit on the 6 speed transmissions too
I've had a few of the escalade 2016-17 with the 8 sp trans, not a great trans, I now have a 19 escalade with the 10 sp trans, it's much better
That's what I want to hear. They all can't be that bad.
I have to join this unfortunate club as well. 2019 Escalade. Catastrophic transmission failure. 100,000 miles. Never towed anything. $8,000 to fix at GMC dealer. Disappointing to say the least. Replaced front shocks a week later. $2,500. No, the don’t cater to the budget minded.
I have a 2016 and mine is doing the something! I purchased extended warranty when I bought it. Time to give them a call smh
Check the codes in computer. See if you have a code for a internal checksum error in the Bose Amplifier. I have these same issues and have that error in the amplifier. I unplugged the amp from the network and the shifting immediately got better. For some genius reason the amplifier is a relay and seems to cause network problems.
How do you check that on the scan tool, like which menu?
@@rideshareg7608 you have to read the codes of the amplifier module. A basic scanner might not do it
I filed a claim against GM and got 12k back for lemon law.
How did you go about filing a complaint
Please let us know how you did this. I just had to take my Escalade into gm because the transmission went to crap on my wife and kid. Not happy.
Please share
Sorry for the late response. I got a lemon law attorney and provided dealer records to show I took it in over 3 times and haven't been resolved
3 transmissions now in my 2017 344.000 miles now slipping again
My car was under warranty, it was that model year when it started to have issues. In less than a year, I took my cadillac 3 times for transmission issues & software. Also, it was unsafe to drive. For sure, my next car won't be from gm
I have a 2015 Escalade with 115K miles and the transmission just stopped working, broke down on the highway. A few years back, I brought it to the dealer with a 'shuttering' or 'shaking' when it was under warranty. The dealer said they changed transmission fluid and that would fix it, when they did that, the transmission took a few seconds to go into "drive" when starting the truck. So, i ended bringing it back. They adjusted the transmission and said everything is good. But, i realized that it was just a bandaide, the truck never drove properly, the transmission would not shift properly and always seemed off. Now, i'm stuck with a bad tranny looking for a shop to replace it... GM\Cadillac repair shops will charge way too much to fix it. I don't think I would buy another one.
This is exactly what happened to my truck
Mine also stopped in a highway when I tried to floor it to pass a semi
Exactly at 115k miles
Just found out the transmission on my 2017 Chevy Suburban LT needs replacing, only 76,000 miles it. I bought the vehicle with 72,000 miles on it, & was about to get the transmission fluid changed in a week or so from now. I noticed an annoying vibration last week, when driving & when the vehicle is in park. Took the Suburban to the dealership to have it checked out & was told it’s no good. Not sure the reason why it failed, hopefully I’ll get some answers on that. Thankfully my warranty covered the cost of a new one.
There is nothing to find out since they are going to replace it. They are shitty transmissions and just go bad.
@critter9773 I just fixed my horrible hard shifts in my 17' yukon xl denali. I drove the car 3 years with horrible shifting issues and thought it would never be fixed. I finally decided to throw some money into it before completely giving up. Long story short, this is what I did:
1.Replaced the transmission temperature sensor. (I had no CEL but it was malfunctioning. The code was always pending but never caused the CEL)
2.Added 20 oz of Lubegard Platinum Trans Additive and new trans fluid.
Those first two steps made a great improvements to the trans but it still had an occasional bad shift.
3. I got a tune from Trifecta Performance. (This made the car shift 99% perfectly) this was a HUGE improvement! It's not 100% but I'm telling you it's 99% better and I'm no longer depressed getting into my car everyday.
I have an 02 Ford excursion that has had a few issues over the years but when it’s broken, it still runs. I was thinking about getting rid of it and getting one of those but everybody says they are garbage. I don’t think there’s any modern used car for under $20,000 that is decent. The new Ford SUVs are ugly, the GM’s are not Reliable, and Chrysler is just garbage. And then, of course, the European stuff, no way.
Land Cruiser is the way to go. That will be my next truck
I have the same problem, taking it in tomorrow morning, GM should be embarrassed. I've owned 5 Tahoes, and now this Yukon. I will never buy GM again. It will be Japanese...will have to suffer through the bad designs but at least they know reliability.
Ford Never used that Transmission they went from 6speed to 10-speed.
The problem with the Cadillac Escalade transmission is the internal wiring harness inside the transmission it shorts out ‼️it’s not the transmission you have to change the wiring harness so it doesn’t short out the electronic shifting so it doesn’t function properly with bad wiring harness in the transmission fluid!
I have 2014 cadillac ats and. My gear shift is stuck in reverse won't come out of gear they replaced the gear shift cable it did it again
@@bradbrown7273 the wiring harness short out in the transmission oil which makes it shift hard or malfunction but maybe the cable is installed improperly if the check engine light comes on then off then it’s the wiring harness usually.
@@craigmartin6826 ok thank you they fixed it Saturday morning it was working fine then it just did to me again
I have a 2017 Cadillac Escalade. I am actually having the same issues that you are. I keep bringing it back to the Cadillac dealership they keep telling me that nothings wrong it’s fine it supposed to do that I think I’ve been there six times recently it’s been getting worse. I actually had one of the tech guys ride with me and I showed him I do have a warrantee I don’t understand why they’re not just fixing the transmission they just keep pushing me off. I am at 75,000 miles. It’s been doing it since I bought it for years ago.
The second the warranty runs out, they ll tell you it’s a problem. It’s a shoddy game dealers play to prevent using the warranty because somehow they lose money on warranty work if they can’t cross every t and dot every i in proving to the manufacturer that there’s a problem.
I have 2016 escalade esv and I did transmission cooler line thermostat bypass and tuned with hp tuners 100k miles no problems
You need amsoil transmission fluid and transmission fluid need to be changed every 30k miles
You definitely need to bypass transmission cooler line thermostat. This is number one why this transmission goes bad.fluid doesn't cool down
But I monitor my trans fluid temp it’s always between 175 and 190
@Critter there also tuning you can do to prevent torque converter cluch from wear do much.if you have hp tuners I can send you link video mechanic doing this on bad transmission and basically fixing shuttering.i did this when my escalade have 30k miles never have any problems

I feel that sometimes Cadillac manufacturing plant gets it right and other times the specs are off but they dont QC it. They just keep pushing it out there
Cadillac cue screen you can buy for 100$ and replaced yourself I just did and works perfectly
Thanks I was actually thinking about ordering one this week and do it myself
Same here , I just did mine
I've done 2 cue screens ebay screen is $30 not a hard job
I have 2015 bought brand new . Same brolem take to dealer to fix too many time
But it was the same
Now the car 71,000 mile
my friend all this problem in a transits from the old fluid and filter i had the same problem in my car i went to the dealer and he ask me for 800 hundred change theme and program i went to my frend mechanic he change me the filter and fluid ang cover gasget for 300 and no more trmbling and the car is great now
every 20.000 change the transmision filter and fluid dont go to dealer
I just purchased a 2015 with only 50k miles and I get the kick when coming to a stop and then taking off in 1st. It also clunks (without going into a neutral for a brief moment like when coming and going from a stop) when the car shifts on its own going down hill with no gas. Now I can't tell if its mental, but I always feel like the car is struggling to shift. Its almost like the car can't decide which gear to go into. I just bought the car and have no evidence if the 50k flush was done! Any insights? Great video BTW.
Same thing here , I have the same problem 1st and 2nd gear upshifting and downshifting harsh. I changed the fluid twice to the upgrade Mobil 1 blue label and still same. I’m thinking about changing torque converter
I have a 2015 Escalade and found it’s a known fact the Torque Converters go. I was told you can’t replace the Torque Converter without tearing the entire Transmission apart… Ultimately having to put a new or rebuilt Transmission in it. Check Engine Light goes on. Throws code. Have flushed Transmission Fluid multiple times. Real headache. My display screen does the same and the Compressor on the AC goes, too!! I’ve had three Escalades. Want a newer one, but am hearing all kinds of bad news about the Motors being junk! Shame because it looks so nice and is the vehicle I have loved having the most.
The screen issue is a very common issue I fix them for a living.
I can help you!

Hey replaced a transmission. Bought a new one from GM BECAUSE I knew any used grant will have the same issue
Thermostat delete boys GM made those transmissions to run to hot air frying up all the stuff
I thought they switched to 10spd in 2019?
In 2018 I think
I have an Cadillac Escalade the transmission and the Coolen for the transmission burn. A car that cause almost 120,000 new and it is not worth it. I was told by the dealership this is a common problem. 8,000 just to fix this shit car. I will never buy a Cadillac Escalade.
my chevy suburban had a misfire and they replaced the engine, and at 176k miles the transmission died, i hate chevy

For 37k I should got a MB nice one but I like the cadi looks way better
Plot twist. He’s driven his truck in tow mode for 115K miles and that’s why it’s broken.
@Petar V
Plot twist...he got so fed up and traded it for a Toyota Land Cruiser
even if he drove it in tow mode for 100K miles it still would not break
