212,000 hard miles off road and street the whole way and my air struts are still good.
What saves it from going bad?
Any updates to your experience?
Well said sir. As an engineer your narrative is spot on. I believe that the system is great and like any great systems it will depend on user and people don’t usually tell the truth because we are mostly trained to be embarrassed of failure versus learning from them and being honest with ourselves. You’ve made every point. Best spoke person regarding air suspension.
I have a question for an engineer 😅
Will there be an air suspension lift with new links bad for the air suspension? My thoughts are that the air suspension in offroad 2 will be too high, out of the max what they can normally go. Or can the suspension more that Jeep let us use?
I think about installing new links for offroad because I have a summit, and i want more ground clearance without removing something from my front pumper ..
Greetings from Germany😁
Unlike many inferior systems, Jeep/Ram's air suspension system is quite robust. It is a "closed loop" system that does not allow moisture to intrude and cause havoc. The bags are three-layer, very hard to tear and making them perfect for offroading. The compressor got an upgrade for '14-current to deal with the "service air suspension" warnings in super cold temps. And yes, it is a nitrogen based system, which can handle swings in temperatures better than other systems. The big failures occurred on early GC on the seals of the shock tower, which is a really easy fix(multiple RUclips vids out there). It is a really good system.
Thanks for the feedback!
I put 280,000 miles on a 2006 Overland QDII Hemi, just bought a 2013 Overland DQII Hemi, looking forward to piling up some heavy highway miles & hit up Southwest Colorado
2017 Trailhawk, zero issues of any kind with the entire vehicle. It's been cross country 4 times, twice towing one ton trailers, and in temps from -10 (in the Badlands National Park in December) to over 100 (here in my home state of Virginia). No issues with the suspension or anything else. It's been out in Moab, been off-roading in Idaho, and been mudding here in Virginia, no issues at all. Oh, wait, let me correct that. We did have one issue early on, a whistle from a gasket in the sunroof that got folded and pinched when it was built. Dealer replaced the entire sunroof in about 2 hours, while I waited, no charge.
I have the same year trailhawk with 44k miles and really don’t want to fork out $3300 for mopars extended warranty. I have another month to make a decision. How many miles does your trailhawk have?
@@Spare_Ribs Only about 28K right now. I'm retired and my wife works from home so we're not putting much mileage on it.
I've got an overland summit with 60k miles. Noticed the front end lowered than the rear after sitting a few days. The local shop estimated the repair around $1200. I researched a few forums. Troubleshooting at home to determine it was the front QL air strut connectors that were leaking. Purchased 2 of them from RMT in FL.for $70 few days later installed the parts and problems is solved. While I was researching I found the front leveling kit at Airlinks suspension via ebay $60. Solved that problem too. Currently running 275 55 20 wildpeak AT3 tires. No rubbing at all. Overall I'm happy with the air ride suspension on & off road. It's a Jeep thing and it's in our Blood. ✌️
How have things been since this post? Any updates?
We purchased a used 2012 Overland last year (2022) that has the quadra-lift system. We love this feature! While we haven't been off-roading with it yet (still learning how it works) the system is flawless. There's 130K on the odometer and I've even wiggled the lines (front shocks) to test to see if the o-ring is deteriorated. But there are no leaks and it is solid. So far, really enjoying this Jeep. It's our 6th Cherokee/Grand Cherokee so far!
This is awesome. I just purchased the same! Really looking forward to it.
Do you know the max tire size we can go with?
@@cape2costa I just went with the stock 20"s Walmart had the Pirelli Scorpions for cheap, so I jumped on those.
have wk2 4wd overland since 2014. 8 years no problems, moved to cold climate and have issues every year when temperature drops below 10 Celsius
I work for FCA Parts & Service for a living and I can tell you this, the QuadraLift System doesn’t have enough common issues to be a Recall, but it is definitely common enough that they shouldn’t be charging as much as they do for replacement parts.
Great post from an EXPERT.
Thanks for this, this was a really, really helpful video. The second of yours that I've seen that impressed me. Good stuff
I had a problem just after I got mine in the winter. Blew an air compressor fuse. I replaced it and have no other suspension issues. Random issue with the keyless start system not recognize key. I replaced all my remote batteries and still have occasional issue but can follow instructions on screen to use remote fob and press directly on start switch and works everytime. I think it's a great vehicle that does many things very well.
I have the same problem the car won't start with remote start. The dealer told me it needs a strong car battery, over a quarter tank of gas and the doors must be locked before trying to remote start. I've done all those things and it still won't start. The owner's manual doesn't mention any of those things so not sure if the dealership's mechanic knows what the heck he's doing.
Mine is a 2020 North edition wk2 equipped with qt2, skid plates, tow package and off road pages among other options. After much research I decided against the air suspension because it would add about five grand to the purchase price as bundled. My choice was to install the Rough Country 2.5” lift combined with 32 inch tires on the stock 8”x18” wheels. These easy modifications increased the static ride height by 3.25 inches for a ground clearance measurement of 11.75 inches. After the required four wheel alignment, driving dynamics were NOT noticeably changed. There was no degradation in ride quality, suspension compliance or wheel travel. However, i have experienced a ten percent reduction in highway fuel economy. As a long term owner, one, I saved substantially on the purchase price and two, Ive avoided potential expensive repairs in the future.
Thanks for the information!
Cold air condenses, seals also shrink in colder temps. This is why they use nitrogen as the main fill gas, as it doesn’t fluctuate as much under temperature changes. The pump is majorly for moving the gas around the system and then filling potential lost volume that escapes during temp fluctuations and heavy bumps. I have a 2012 and have only needed to replace seals on the front towers.
Have 225k miles on my 15. We had a 50 degree temp change in 1 day and I just got my first code.
The main reason they use nitrogen is because it contains no moisture. Air has lots of moisture. And moisture freezes in cold temps, causing the compressor to freeze up.
Good overview Brad. I have a 2018 Overland Quadradrive and its excellent for towing and offroad. But most of us spend our time on the road as a daily driver. Thus the air suspension is ideal to provide an excellent lift when off road. I wouldn't want to drive daily on the highway with a permanent 2.5" lift. It would drastically change the enjoyment of the JGC vehicle. That's the benefit of the air suspension. Thanks.
Thanks for watching and for the comments
157k miles on a used Overland Edition with air suspension, mainly highway miles for work, but when I take it on trails that are more about inclines and declines than rocks, it handles great, haven’t taken it on a rocky trail yet! It also works great with towing, and no issues yet.
I think that after using 1 jeep with ql and 1 jeep without ql for a few years, I see its benefit for the grand cherokee. I think i wouldnt want to daily drive it as a lifted vehicle and compromise the handling of this very luxurious jeep, but a lift sure is nice to have sometimes. A stiff ride is worth putting up with in these cases for me. It adds to the swiss army knife appeal that drew me to the vehicle. My biggest complaint is perhaps my own fault: that I added some really stiff tires to my wk2 (2013 overland with ql). They are light truck tires. LT275/55R20. I have found that the combination of a stiff tire with my ql is really not good on the road in normal ride height. The suspension is really soft while the tires are stiff so when i hit asphalt bumps on some corners i have seen really dangerous behavior from the jeep. It will completely change direction without input. Same dangerous behaviors on loamy backroads or potholes in gravel. For this reason i run gravel roads in offroad level 1 which makes most of this behavior more tolerable. Im hoping it doesnt put me in a ditch one day on the asphalt. I am definitely changing my tire selection for the next set. I also saw a safety test of the early wk2 (stock) which it failed horribly (moose test) and the later jeeps handled it better, so this could be a natural characteristic of my jeep coming out due to the stiff tires. My wifes jeep has none of these behaviors (spring suspension 2014 wk2 limited with xl rated stock size nitto tg g2s). My review of quality is maybe surprising. No issues with the ql at all in 75k miles on the overland, however we did have bushings fail and started to hear a noticeable clunk in the front of the limited jeep with standard suspension at 80k which in my opinion seems premature. As an engineer, I think 10% is an alarming and unacceptable failure rate for the ql system... hoping mine holds up for the long run.
Thanks for the feedback! It seems like there may be a new airlift system in the new Grand Cherokee
I find myself in OR1 most of the time off road, until encountering rocky outcrops and then I go to OR2 .... after 4 years and 55K miles, no issues with Quadra Lift suspension, despite hauling a dirt bike on a hitch hydraulic hauler. Great video and thanks for sharing!
Good thought! Was always wondering this between OR1 and OR2.
Thanks for sharing!
212000Km with very limited off road use and air compressor overheating. Rather than handing over almost AUD$6000 to dealer to replace the compressor will definitely have spring conversion, with 2inch lift kit plus air assist rear, for AUD$5500 and not have to worry about it in future. I may not do a lot of off road, but when I do I want to be sure no issues when out there enjoying myself. Thanks for great summary Brad!
I have the air suspension system on a 17 overland absolutely love it no issues thus far, I do tow a 22 footer center console and it plays with it.
Great video Brad as always...
2018 TH v8. Had a problem with air suspension couple months into ownership. Coincidentally it also happened to me under cold weather. Compressor replaced under Warrenty. No issues since. I’m using it off-road and like others mentioned OR1 is the preferred setting until OR2 is a must. It’s definitely more stiff but not unbearable. Love the TH and always impressed how after a long off-road trail you get on the highway and just cruise away...
Thanks for the feedback!
2011 Overland GC. Got it used about 7 years ago. Lift system got a hole in an airline right after I bought it. Lots of issues since then. Warranty covered around $8000 in repairs. Ended up being a $15 relay. Trouble free for the last 5 years. 180,000+ miles currently and lots of problems again. Replaced 1 air shock with a remanufactured unit. Spent about $500 with install. That wasn't the problem. O rings were leaking. Cheap and easy diy fix. Probably need to replace rear air shocks next. Aftermarket is cheap for these and the rear units are easy to replace yourself. Love my GC even though it's been in the shop every 2 months. Now cylinder deactivation has rounded the cam and I am going to have to put in a rebuilt engine. Got a Diablo chip and deactivated the cylinder deactivation. Wish I had known about that a couple years ago. Would have saved my engine.
Thanks for the advice. I'm trying to decide between a Loredo build vs buying a Trail hawk. I've heard personal issues of friends that got moisture in the lines, and it cost $3k to fix so I have my concerns. A $3k cost to fix is a good coilover/ reservoir system.
Excellent video, Brad. I don't do Facebook, and so I'll comment here, and also ask you a few questions. My 2015 GC 4x4 Overland Diesel w/ QuadraDrive II and Quadralift has only about 57K miles on it. Quadralift has been occasionally quirky, mostly in extremely cold temperatures. It is regularly taken off road on demanding trails in northern Michigan near our Cabin on the Manistee River. A couple of buddies and I managed to get severely stuck last Saturday (in 4-Lo and Offroad 2 height), and so we had to use my shovel, all 4 recovery boards, a come-a-long wire rope winch, hi-lift jack, and heavy tow chain to get out. An electric winch would have been nice, but probably would not have been usable on the front end of the WK2 in the spot where we got stuck. (A winch that could be portably installed into a front "tow hitch style receiver" and also wired to be usable in the rear tow hitch receiver would be ideal in my book, as I am usually traveling solo offroad.) I like the versatility on-road and off-road that you describe in this Quadralift video -- I have had very similar experiences. Our place in northern MIchigan is about a 2-1/2 hour mostly expressway drive from our home in Southwestern Michigan, and the benefits of driving at 80+ mph on the more remote northern sections of expressway are felt very clearly in my "luxury" WK2. When I had to take my GC in for an EGR recall last week, the dealer lent me a new Gladiator. Despite the longer wheelbase, the ride in the Gladiator felt like I was driving a beachball down the expressway, and I had to constantly correct the steering while doing about 75 mph (with a 20 mph crosswind). That would start to become fatiguing on any ride longer than an hour, and this does NOT happen in my WK2 with the Quadralift suspension. I have also researched the Rocky Road/Old Man Emu conventional spring replacement system (for when my Quadralift eventually goes out). I find that with all my additional bash plates (factory skid plates, Mopar Rocksliders, Chief Products Sump Protection Plate and Lower Front Guard, slightly larger/heavier than factory 31-1/2" Goodyear Wrangler Duratrac tires, the possible addition of a winch plate and the winch itself, plus a few other protective bits and pieces) all of that extra weight will be a huge factor when trying to dial in appropriate spring rates, lift height, etc. once a replacement is in order. I am presently considering adding the Chief Products hidden winch mounting plate system along with a 10,000 lb Warn Zeon synthetic rope winch, but I am very concerned about the added weight this will incur on what has already become a rather heavy vehicle. I would be interested to find out anyone's experience with replacing Quadralift with conventional-style metal springs on a very heavy WK2 build, e.g., Diesel, with lots of extra stuff that adds a lot of weight. Also, whether the Rocky Road/Old Man Emu metal spring system would be compatible with all of the aforementioned Chief Products items. (Sorry for this waaaay too long comment, but I wanted to get it all in, rather than send it to you piecemeal.)
Thanks for the comments. I personally haven’t dug into the conversion specs too much. I think it’s on my “cross that bridge when we get to it list”. Sounds like a proper winch would be helpful. The woods of Michigan are what prompted me to get ours.
Excellent stuff here! Great survey results.
Thank you so much for this information. I just found your channel yesterday and have watched a ton of them so far.
Just bought a 2021 WK2 Overland. It didn't come with skid plates like a trailhawk does. Any suggestions on where I should start looking? And what else I should consider? I should probably mention that I've never actually done any off roading yet. But I'd like to make sure that when I take my jeep out, I dont wreck it on my first trip.
Come out with us! We have mostly Chief Products as our skid plates. They have done great. Also six monkeys makes good gear.
@@ProdigalOverland Oh I'd love to! I just have to convince my wife that we want to use our vacation time driving down from Vancouver Island, Canada.
I have a 2013 Grand Cherokee Trailhawk with 146,000 and no problems with the air suspension at all. I don’t do any off roading but have used it for hunting and ice fishing out in the Berkshire’s of Massachusetts where the roads are pretty rough. I live on Cape Cod now and tow my boat to Cape Cod Bay and have done some off road beach/sand driving. No problems so far.
My 2017 GCTH has 38,756 miles and no problems with air suspension. Ride is still at level two. Good video. Thx
Thank you so much for posting this! I’m moving from South Florida to Michigan this fall and have been considering a few SUV’s over the past few months. The Jeep Grand Cherokee honestly seems like the best overall bang for your buck and now over the past month I’ve just been trying to figure out what trim level is best for me. I ultimately think I’ve decided on buying a used Overland but knew in the back of my mind that I’d most likely need to buy an extended warranty due to the air bags. This was a very cohesive well put together video that highlighted all areas of possible concern and also reassured me that this system is VERY reliable and that I’m making the right choice here. Cheers!
Thanks for the feedback. I’m glad it was helpful!
How did things go?
I would agree with the idea of replacing the system with an after market coil system if mine was to fail after warranty. I've dealt with Rocky Road Outfitters in the past for rock rails and roof rack, they are good guys and make a quality product, I'd trust them with the suspension.
2016 WK2 Summit Diesel, 80,000 miles, Colorado off-roading 50-100 hours per year, Maxxis 275/55 R20 Razr AT tires. No issues with air suspension. Rear shocks replaced under warranty at 60,000.
I have a 2015 Summit Ecodiesel. No suspension problems ever, but I was wondering if you have issues with the DPF wanting to regenerate while off the beaten path? I'd like to get skid plates and rock rails on mine and use it off road, but I'm worried the DPF wanting to happen when I'm in BFE.
I have a 2014 Jeep Grand Cherokee overland only problem I had Was when the temperature went below 0 a warning message came up saying service air suspension but when it warmed up everything is fine other than that love the quadro system
I'm the owner of a 2011 jeep Grand Cherokee Overland. I don't do any off roading. Now if you have one still under warranty or if you got an extended warranty. Then you won't have to come out of pocket for repairs. Regarding air suspension related issues. However if you don't. Be prepared to spend a lot on repairs. In the last 5 years. I've had compressor issues and strut issues. My Solution to these issues. Were to just take out the air struts and put on. Regular standard shocks and struts.
I had problems with my air suspension, three days after purchasing my used Jeep Grand Cherokee Overland. It cost a few hundred dollars to repair.I have a spare pump from a wrecker for future use. Right now, it leaks
FRom the front, and I have to get it fixed. I wanted to mention that the JGC HAS 10.5 IN. of air travel. Highest in its class. It certainly makes a
difference, and I don't Want to be without it...
Great videos! Thinking of getting an overland what's the max tire size you can run without rubbing on quadralift?
have wk2 4wd overland since 2014. 8 years no problems, moved to cold climate and have issues every year when temperature drops below 10 Celsius
2018 Trailhawk GC. Current mileage 94km / 59M Air suspension problems started early… 2 compressors, 1 module, replaced lines… today blew out an air bag… at a loss of which direction to go… repair again? Or convert… (warranty ended 3 mths ago)
When it does work… it is awesome. Ugh
I have owned my 2013 Trailhawk for 8 years and have only had to replace the two rear airbags. I also live in Minnesota and the cold never affected it.
Only one bag was bad. It was leaking. Replaced them myself in like an hour and half. $400
Pro: setting it to offroad II makes it trivial to work under your jeep. Try changing an O2 sensor on normal mode vs offroad II.
Con: if you have a slow leak in a tire then the air will run 24x to compensate that section and eventually your compressor will crap out. Do i need to remount the tire with some tire bead? Do i need a new blutooth tire stem? Wish i woulda fixed that instead of "ill just put some air in my tire every month". Now i have a compressor thats almost worn out at 165k. Also dealers dont really like working on quadralifts so they just go right to the last option and say to replace the pump for $4k. When maybe all i need is a new valve on a rear bag and maybe a nitro recharge.
But take it from me, you will love your quadralift until the day that you see your jeep sink. And then its a $$$$ nightmare and you'll try to unload your lemon. When your computer starts seeing the problems,it kicks on the stability light, and then you cant shift into reverse or drive. But you do have 2 secs at startup before that light comes on so its a race to throw it into reverse so you can go to work.
My fav pro, I put it in park mode, back up to my trailer, then put it in off-road 2 and watch it lift the trailer up. Don’t even have to crank the trailer jack.
I bought a used 2018 trailhawk (80,000km or 50,000miles) 1 yr ago and the air ride compressor failed within the first month of ownership but was covered and replaced by the dealer at no cost to myself. I live in Toronto, Canada and have had zero issues with the air ride this past winter. Have not had any other issues with the Jeep knock on wood.
Ooo first to comment! Great video! You produce really good content. How is a guy going to blame the air suspension for a deer impact?? That's pretty derp...
On 2019, bought a pristine 2012 GC Overland Summit at 52K miles for a great price, but did not buy an extended warranty at the time. 2 weeks later suspension was "low-rider". Took to dealership and was charged $1750 for leaking front left strut and $3300 for compressor that burned out trying to compensate for leak (I wish they had better visual warnings about compressor overuse!!)
Now at 123K still working, but getting intermittent "service air suspension" lights, which I suspect are an electrical issue, HOPEFULLY.
All I’ve seen on my 2017 summit is if you raise and lower too much in a short period it will give you a message saying the system is too hot and needs to cool down. Gave it a few mins and worked fine
Have a 2021 Overland WK2 that I will replace with coil overs once we have problems with the Quadralift system.
I'm not on FB so didn't see the surveys but I have about 160K on a 2015 Overland with the air suspension and live in North Idaho where we deal with cold winters and snow. I haven't had any issues with my suspension. Fingers crossed.
Thanks for the feedback!
Michigan here. so far 66k miles and no problems. I also have 20" off road tires Nittos Grapper 2
I owned a 2014 Overland for 4 years that I did take off road about 10 times and also used when I serviced accounts way out in the country and did a lot of driving along gravel and dirt roads. I did have a few little issues with it acting up and becoming unlevel from front to back or not responding to the selecter. But usually just shutting off the Jeep and restarting it would reset that. I didn't have any mechanical failure in about 65,000 miles of driving.
During general on road or gravel road driving it wasn't a bad system and road fairly smoothly. I liked that I could lower it for people who had problems getting into a higher height seat. However, going at speed if I'd hit a big dip that would cause full rebound, it would have a very hard stop to the suspension droop, much harsher than other vehicles. I don't think it was really damaging anything, but it certainly felt like it was much harder than it should have been and should be a little more cushioned.
My biggest gripe about the system is when you put it in one of the raised positions. Even off-road 1. The suspension really behaves opposite what it should do for its height goals. When you're on the road, and especially at higher speeds when it drops another half inch, you want a car with a little stiffer suspension for better handling. When your off-road, you want a soft compliant suspension so it can conform to the train and keep traction and not beat the crap out of you. The QL unfortunately does the opposite. The lower you put it, the softer it becomes, and the higher you put it, the harder it becomes (nature of air bags) to the point where it's so stiff there's practically no compliance and it's both a very harsh uncomfortable ride, and any uneven terrain at all and at least one wheel is lifting off the ground. Honestly, I hated the system for off-roading.
This is why it make me so mad that they only offer that QL system for the Trailhawk. I'm currently looking at getting another smaller or midsize SUV that I can go off-roading with, and that knocks Grand Cherokee out of my list because I don't want that system. Even if I get another Overland, that's the only suspension offered for it. But I want the amenities like the adaptive cruise control and ventilated seats, but I can't get those options in the lower trim levels that don't have the QL suspension. So I'm considering a regular Cherokee Trailhawk that can be loaded with all the amenities. And it has a raised, more off-road worthy suspension and a true, mechanical locking rear diff. I think it was a really bad idea for Jeep to come out with a trail focused Grand Cherokee and then put the QL suspension in it. They should have stayed with a more traditional but lifted and more rugged suspension.
Overall I'd say it's a great system for just on road or light off-road trails. But if you're looking to do anything more rugged, then maybe consider other options.
This is precisely the issue i've been so badly disappointed with my JGC EcoDiesel with QL.. I thought it would be an especially off road capable machine. However this past weekend I took it out on a local trail only to find it is quite the opposite due to the QL system. As soon as I traveled at speeds over 5mph, the suspension would bottom out extremely hard.. so much so that my passengers were not having a good time. Such a bummer!
I love mine and I don’t buy it to off road I use it as a daily and I have it lowered and tuned up for power that’s why the only motor I buy is the hemi
I have had zero problems and I live where summers are above 100 and winters are well below 10 degrees F no issues here
I’m in the UK and have an Overland WK2 with air suspension. 70 thousand miles and totally trouble free mainly on road driving with some off road trail driving.
Hi, Thanks for the video. Generally, the air suspension systems are very reliable and have been used in trucks forever. I had the same problem as you when I was out in the trail, the front lowered, and the back did not lower to normal ride height. I had to limp all the way home. When I brought it to the dealer he set re-set the system and things have ok now. So, same as you I have this thing in the back of my mind. But, as long as you know how to re-set you should be able to fix any issues with the sensors.
So how do you reset ?
So disconnect battery to reset?
I know this is a old video,, but SO far with my 2013 jeep Grand Cherokee Overland Cycle the air system a couple times a month all the way up all the way down I have not had any problems. Maybe some of the problems are from not using the air system, Leave it set in one setting to long it might get stuck from not being used?
My question is does it have a valve to empty water from the system? Most air systems that use compressed air have water build up in the system and needs to be drained.
I don't think I voted on either of the groups (45th not trailhawk, so only one possible anyway.)
I bought my 16 used. Drove a ton of miles for work, like 1k/wk+. Nice to have the variability. Went camping etc, never babied it. No issues.
If it goes I'll replace it with oem or equivalent bags because it's a major reason I got the wk2
This was soooo helpful. Thank you
Hello Prodigal Overland, great content with first hand experience knowledge. You mentioned converting a Quadra Lift suspension system to a traditional coil suspension system, so can you explain this further in detail. For example, the pros and cons, Quadra Lift vs. Coil Lift cost to replace, including coil suspension system brand recommendations for a Jeep Grand Cherokee Overland.
Keep on Off-Roading,
Dan
Works great for me, Use it every summer for fire watch in Oregon.. 48,500 miles
Just got an ‘18 Trailhawk with the 5.7. Do you have a video of how you would prioritize after market accessories, and why you chose the brands you did?
ruclips.net/video/v-6wdwVbH8w/видео.html. This video talks about what kind of upgrades to get after a good set of tires.
Thank you!
Is there any other benefits besides lifting and lowering? Ride quality? Active suspension in corners(preventing body roll), changeable suspension modes (softer in comfort mode stiffer in sport mode), ride leveling when loaded down with cargo/tongue weight towing a trailer. And the biggest one is Land Rover people say something “cross lock” so it can’t least attempt to behave like a solid axle and try to articulate better
Hi Brad, I'm in New Zealand with and Grand Cherokee limited S 2013 that's an inport from the UK and it has 87000km and the Quadra lift works great not issues.
Awesome. Thanks for the info
Subbed - thanks for solid information
I have a 2014 grand Cherokee summit. Bought it use with a 160,000 high way miles. We live about five miles off the highway so it now sees a fare amount of gravel road. One month after buying it we blew a rear bag in our drive way so I backed it into our shop and bought a 120 dollar after market air spring and replaced it. Another month goes by and blow the other air spring. Took it to our dealer. They told me I needed to replace both rear air springs and one air line. Cost to do this 2,900.00. I now trailer my jeep home and bought 2 rear air springs for 450 bucks. Hoping I can install them and bring it back to recharge the nitrogen. Let the headaches began.
Shhh. Nobody cares Tony.
How did it end up working out. Did you have them refill with nitrogen?
my only issue is the lack of flex with the air suspension offroading, and the compressor is loud at times
What’s the biggest tire you can run with this air suspension
I know QuadraLink will be offered on the new Grand Cherokee L - what package triggers the addition of it on the Limited? From what I have heard it will come standard on the Overland and Summit but will be an option on the Limited.
The only thing I don’t like is the inability to override auto settings. Example, in Sand mode it self adjusts the lift to normal ride height. At the beach, with deep ruts and soft sand, I would prefer to fine tune the height a bit up to avoid the bottom scooping up sand. I understand it may be for dune running and you want to have some stability when going fast but not everyone has dunes to blaze through. Other than that, it is very well executed.
Do you have a link to the conversion?
Only issue we have had was a rear bag bust.
Got an aftermarket one off Amazon and replaced myself, easy to do.
We have had to replace the fittings on top of both front struts as they were leaking at 100k. Am replacing a rear bag at this moment, 133,000mi.
My Sweetie loves the air suspension as she is height challenged. But it rides terribly harsh off road.
As always, Brad, very informative video. One comment from me: you and I have discussed situations where and when the Quadralift air suspension gets "quirky"; e.g. either will not immediately -key word- raise or lower but does so/responds after a certain, usually very short, period of time. In other words, it fixes itself.
For example, after my flat tire on my JGCTH's first off-roading trip to Rausch Creek in PA, and the change with the spare tire, it would not lower...but it did so after about twenty minutes or so. You added your own similar experience(s).
Yes it does at times! Enjoy that new grand baby!
Prodigal Overland thanks, Brad! I hope to go see her tomorrow.
On another subject, I need to put 1000 miles on my Trailhawk so that the dealership's mechanics can figure out where an oil leak originates; they put an "oil leak kit" with dye in to detect the cause of the problem. I now need to race against time as I am leaving for Greece at the end of the month! 😂
@@MrKozanitis more driving!
Prodigal Overland indeed! :-)
Do all 2015 over lands have the Quadra lift?
Hey, i just wanted to say i really like your show!
You have a great way of explaining things and breaking things down for beginers.
My name is ryan j. I have a 2016 cherokee limited, but man i wish i would have had the cash for a grand cherokee. Ive owened 4 older grands back to back. All with the straight six engine. (I miss those 😃)
Do you have any videos with cherokees on the trail??
I saw one video where a guy had a "jurassic park" cherokee stock. He said he made the trail with no damage, but there was no footage of him on the trail. Did he do the same lines as the grands? How do you think cherokees do out on the trail vs. A grand?
Also if you have any pointers on the first upgrade to do to my jeep. I have good all terrain tires.
I was thinking either a deer catcher or a light bar to start(im a chef and live in wisconsin so...)
Any ideas are appreciated.
Keep making great videos!!
Take care friend,
Ryan Johnson
Thanks for watching I’m glad you found us! We have only been a couple of times out on the trails with Cherokees. The biggest limitation so far has been the lower ground clearance. If you’re looking to be more off road capable, looking into a lift might help. Have a great day!
Hi, do you know of any good conversion kits (from air suspension to regular suspension)
I have a 2017 Trailhawk with 93,000 miles and in the past couple weeks have had the air suspension system fail to operate at times. It is intermittent failure to return to normal ride hight. The dealer says codes indicate overheating in the compressor. The dealer indicated parts cost of around $3,900 plus labor. I am undecided as to whether to have it fixed.
So what have you done afterall?
@@akov595 I got the dealer to replace the compressor. All has been perfectly fine since then. It was cheaper than a new car.
I should add that in the end, I think the problem was at least exacerbated, if not caused, by me towing a trailer of around 10,000 pounds over a road with some dips.
I don't think the air suspension system is even available anymore on the new 2024 Grand Cherokee. I also didn't see that the Trailhawk or the SRT are available anymore. Also, the only engine available is the V6. I have a feeling they are going to faze out the Grand Cherokee altogether in the near future!
What is the best lift mode to keep the Jeep in when not going off road? Is it harmful to keep it in the 1st lift mode at all times?
The air suspension will automatically lower out of off road 1 or 2 settings once you go over 35-40 miles an hour.
Have a 2019 overland with OR2 and air suspension I got the extended warranty no issues as of yet
Great info... love the fact that you did surveys! 2021 “Trail Rated” JGC with Quadra Lift towing a pop up... self-leveling is nice! No extended warranty... like the 80-90% with “no problems”.. limited off-road, it’s GREAT to drive... 🤞🤞
I just bought a 2011 WK2 Overland with the QuadraLift system and tonight it started giving me errors and overheating codes. Which is why I've been digging through your old videos trying to learn the most I can about the system. I love the ability to change ride height, something I needed with my lifted WK that nearly took out my tiny garage. I do know that if I cannot fix the system I will have to skip to lifting it and adding 33's like the WK has.
If it's overheating, it could mean that there's a leak in the lines. The compressor is continuously running trying to keep the shocks pumped up but can't because of a leak. This is very common due to the o-rings sealing on the air lines deteriorating. You can get replacement fittings with new o-rings in them on Amazon for under $60 a pair. Replacing them is a super simple process and just needs to wrenches. There's plenty of people on RUclips showing how they replaced it. Once the airlines are sealed, the compressor will stop running when the shocks are at the set height.
@@ekummel thank you, the might be some stress to it. But I actually discovered the problem, and another at the same time. My lift wasn't working because I checked the wrong fuse "don't have a friend read you the diagram" and the sound I thought was the pump running was the front fan rubbing against the cover to the radiator hose as the clip broke that was holding it barely between the fan and pulley system. It whined like I thought a mini compressor would if it were overloaded.
Had an issue with my ‘15 overland quadralift. Covered under extended warranty thankfully. It was being really buggy but 3 separate over night stays at the dealership and $5000 in repairs took care of it. Ended up being the valves on the front air bags. Got a new compressor out of the deal so wasn’t all bad! Love the system but I do worry about it a lot since warranty is done now.
You have had it for 5 years,and then paid 5000$.. not bad i think because all those 5 years you were enjoying with your grand cherokee:)
@@volodymyrprosov6134 Agreed!
Bought a 2022 Jeep Grand Cherokee, Summit Reserve (redesigned JGC) and the Quadra Lift system (front suspension) failed at the 3,950 mile mark after 7 months of ownership. Prior to the Quadra Lift suspension failing, the infotainment system had to be replaced due to faulty operation and the Quadra Drive II system threw warning lights that mechanics could not later discern. I DO NOT DRIVE OFF ROAD, and only drive about 600 miles a month. Thank God I bought an extended warranty. IF YOU ARE IN THE MARKET - DO NOT BUY !!!
109,000 miles. Popped a rear air spring yesterday. $109 to replace and took about 15-30 minutes
Rear i am guessing? And can you just replace a air bag and not refill nitrogen?
Okay extended warranty costs like 6000$ and it covers for 5 years. Airlift suspension like works 5 years in 80-90% flawlessly. Who didn’t buy extended warranty,maximum they are going to spend on air suspension around 6000$ in 5 years or even spend nothing. The only big pros of extended warranty that it covers another problems too. I think like both ways are fair. Love my grand cherokee trailhawk 5.7.
Airlift suspension works well,and i am happy)
Thank you for your video!
P.S. after your 5-7years just trade in your grand cherokee to the next generation)😅
And save money for any expensive conversation for coil springs with added 2-3 inches height and get disappointed on highway? Not good as for me) also probably it will cost up to 6000$ for everything including labor fee tires upgrades etc
Probably will be better to trade in for next generation short base trailhawk and pay that 6000$ for the extended warranty and just enjoy and be happy with all your 32 teeth :)
When we bought our 2017 we went with the lifetime warranty for an additional $3,500. We tend to keep our vehicles a long time (just sold my '99 GMC and our other vehicle is a '97 Dakota 4x4 my wife bought new) so we figured it just made good economic sense given the expense of repairs on today's vehicles. The only things not covered are wear items like brake pads and wiper blades and there's a $200 deductible.
@@life_with_bernie it’s so cool!!!
@@life_with_bernie the only option I might get it was 6000$ for 5 years/100.000 miles
@@life_with_bernie I got the same deal on my 2015, no way I would buy a 4x4 rolling computer that rides on air without a lifetime warranty. One electrical problem could cost $3500 easy.
What is the name of the modules under driver seat for air suspension 2013
I have 2012 wk2 with 156000miles and still going and only problem I have with air suspension is when temperature drop below freezing. Do to the age of car unfortunately I have only air in the system as such when it get cold it freeze air pump and fixings. Apart that nice car which live his own life like I said before lol. Thinking now about wrangler rubicon because you can do more with it and go further. Problem with good off road car is that every time you got better one you need walk further to farmer to ask for tractor lol
Nice!
I just bought one. 3k miles and no issues.
I bought the extended warranty also, just incase
Good move
Anyone else have a knocking issue on all four corners with their QL on wk2 JGC? I have to keep mine at low speeds of around 5mph when going through any dirt road which is not perfectly smooth, otherwise the air suspension makes tons loud banging noises such as though i'm slamming into a bump stop.. I've had plenty of Jeeps over the years and this is the only time i've been disappointed off road by one.
the WK2 quintessential channel.
I got air suspension but ride height not working everything else works fine
Doesn't look like a plow or any sort of cultivator, maybe a planter?
When I am in level 2 it seems like it hits the rear bump stops. Has anyone else had this happened?
Yes, it's very hard. Not good for offroading.
2017 Trailhawk no suspension problems 120,000 miles
my passenger rear airbag blew up at 119,000 k miles, I Own a 2014 wk2 overland with ecodiesel
it cost me 100 bucks on ebay for 2 air bags, then anther 800 when it was said and done to Get my mechanic to install their bags they're bags and also bring to dealership to recalibrate their bags
Do you always have a humming sound on your air suspension when the engine is running
Never
No not a humming sign. But you can hear the air compressor from time to time.
Any thoughts on a 2014 Overland with a diesel for towing (not necessarily off-roading)?
Diesels to tow, uh yes 👍🏻 😁
@@ProdigalOverland ...it’s got 236,000 miles on it. What do you think now? Buy or pass?
Would like to see a similar poll and video on the WK2 diesels. I would really like to to have one for towing in the weekends and daily driver during the week. I seem to only hear the horror stories. It’s hard to tell if that’s an accurate representation of them.
You guys are lucky. Extended warranty here in Saudi doesn't cover air suspension. It's really shame.
Sallam Fahd... I am planning to get a used JGC Summit... But I am bit afraid of the air suspension... So my question is it worth it getting and maintaining an air suspension here in the GCC?.... Happy Ramadan
@@kareemhaddad6741 what year? What is the mileage?
@@fahdabdulaziz5067 2016....around 80,000 Kilometers..but no warranty
@@kareemhaddad6741 well i would say it depends. If the air suspension fails, it would cos you alot of money to repair and not alot of people know how to fix it outside the dealership. The air suspension is great when works but when it fails, it's a nightmare. If you can afford the cost of fixing air suspension i would say go for it. The car is great and at least in my experience, i haven't faced any real problems so far.
@@fahdabdulaziz5067 thanks my friend for the reply... To be honest I am willing to take the risk for the comfort...
My compressor and valve block needed replaced costed 2300,
I’ll be deleting QL in a future video replacing it with King coilovers & I’ll explain why it’s the worst option for OFF-ROAD.
I'd definitely love to watch that!
I agree, hated QL for offroad.
My jeep doesn't quadralift and I prefer that as I can buy an 2.5 inch lift and keep the ride quality
i would say it could just been the condensation that builds up
There are already many very good quality replacements for air suspension on the market, so you no longer have to pay thousands of dollars for repair
Is there going to be a 2022 Jeep Grand Cherokee Trailhawk?
I sure hope so.
When your next trip to rausch. I would to test out my 2018 trailhawk out.
