Suspension Problems of GMC Yukon - part 1

Vehicle shifted into neutral while driving down the highway, extremely dangerous. Would not shift into gear and could not accelerate. Was able to pull over and the vehicle would not restart. Had to have the vehicle towed to a dealership. Dealership found a blown fuse, problem happened again twice and the dealer could not find the problem. This was July 28th, 2026. On August 20th, while in cruise control, slight ringing noise began, then a loud thump, then a loss of oil pressure. Unable to do anything other than pull over on an interstate with my family. Again, very dangerous. The vehicle would not restart and could not be shifted out of park. Had to have the vehicle towed again. Have also had at least 8 recalls on the vehicle. Unbelievably dangerous situations with my family, aside from inconvenient and expensive.

We took in our Yukon for the recall letters we’ve received in the mail and to check a suspension light the popped up. Our Yukon was given back to us with the ac not working properly anymore and it started to turn off on us out of nowhere. Now we need an engine replacement. What’s more aggravating is that the Yukon was checked out the week of july27 -31 according to service advisor the engine was good and the only thing needing to be replaced was the module for the suspension light that popped up. Now it turns out that it doesn’t even need a module replacement and the suspension issue is something else. Super frustrating it’s our only family vehicle and it so upsetting that we were given the Yukon back in the condition it was in. Thank goodness the Yukon shut off at a drive thru and not a freeway or my husband would’ve got into an accident.

My 2023 GMC Yukon denali xl, used as a commercial vehicle for my business, experienced sudden and complete engine failure at approximately 70,000 miles with no prior warning. No check engine light, no unusual noise, and no other symptoms. The vehicle had previously been inspected/serviced under gm safety recall 25v-274 (l87 engine loss of propulsion) and had been deemed safe prior to this failure. The failure occurred while driving on a two-lane road in durango, CO. The vehicle lost all propulsion and came to a stop in the roadway, blocking the lane of travel and forcing other vehicles to cross into the oncoming traffic lane to go around the disabled vehicle. This created a serious and immediate hazard to myself and to oncoming traffic. The vehicle was not driveable and had to be towed. The dealer confirmed catastrophic engine failure requiring a complete engine replacement. After the engine replacement, the morehart murphy GMC dealership in durango also failed to properly recalibrate vehicle sensors. They did not reinstall certain suspension components that had been removed for the engine replacement, requiring multiple additional dealership visits to resolve along with recalibration of the air ride suspension. After the replacement I was getting messages that the vehicle was "too low to drive with caution" and "reduced acceleration drive with care. " this vehicle failure occurred during our peak season (June 10-July 2). The vehicle being out of service, I was required to rent a replacement vehicle at my own expense because gm did not provide a loaner vehicle. I estimate loss revenue at $1k/day. When I attempted to raise this issue with gm directly, their response was to submit letter to a p. O. Box, with no other means of resolution or contact offered. Given that this vehicle had already undergone the recall remedy and was represented as safe, this incident is relevant to NHTSA's ongoing investigation into post-recall l87 engine failures (recall query rq26001).

The vehicle has experienced recurring suspension, drivability, and pulling issues associated with the 4-corner air ride leveling suspension system since early ownership. The first major incident occurred at approximately 4,600 miles when the vehicle displayed suspension warnings and would not accelerate properly past highway speeds. Since that time, the vehicle has repeatedly experienced pulling during acceleration, unstable ride behavior, suspension/leveling concerns, alignment-related issues, and drivability instability. The problem has been reproduced multiple times and documented through approximately 16 repair visits and roughly 74 cumulative days out of service. Dealership service records include repeated suspension inspections, drivability evaluations, wheel alignments, and related repair attempts. The issue remains unresolved and the vehicle is currently back in service again for the same concern. The recurring pulling and instability create safety concerns because the vehicle does not consistently track properly during acceleration and normal driving conditions. Suspension warning messages and drivability symptoms first appeared early in ownership while the vehicle was still under factory warranty. I have also found many similar owner complaints online involving the same suspension system in comparable gm full-size SUV models.

The suspension service lights repeatedly coming on.

Air bag suspension does not work in sub freezing temperatures. Vehicle bounces up and down excessively and is extremely unstable and unsafe to drive at any speed. Vehicle speed was limited to 56 mph. Dealer stated that this is a known flaw but not recall has been issued. This is a design flaw that GMC should be responsible to correct.

In 2024, while the vehicle was still under warranty, we brought it to our gm dealer due to an air suspension fault. The problem typically occurs in extreme cold weather, and following that visit, we did not experience further issues during the remainder of that winter as it was never that cold again. However, the following winter the same issue returned and was diagnosed yet again, and this year we are again experiencing the identical problem with the same diagnostic code which has been diagnosed by 2 dealers and a private mechanic in the last week. It has since become clear that the underlying issue was never properly repaired during the 2024 warranty visit. We recently learned that approximately 3. 5 weeks after our 2024 service appointment, gm released a service bulletin outlining the correct repair procedure for this exact issue. We were not notified of this bulletin by the original servicing dealer. This information only came to our attention when we brought the vehicle to a gm dealer last week, where the issue was properly diagnosed and now they are refusing to fix it without us paying $4300 even though it was brought to their attention in 2024 while under warranty. A failed air suspension presents a safety concern, not merely a ride-comfort issue. When the system fails, the vehicle may sit unevenly or at an incorrect ride height, which can affect vehicle stability, steering response, braking geometry, and traction—particularly in cold weather and at highway speeds. Because the failure is intermittent and temperature-related, it is unpredictable and increases the risk of loss of control. The vehicle is not operating as designed when the air suspension is compromised. Gm knows about this issue as they did indeed issue a bulletin that covers our vehicle and this was done when my car was still under warranty, but it was not brought to our attention that it existed until this year after the car's warranty was up. 2 seal kits, air springs and the struts!.

When driving at slow speed and wheels turning right or left you can hear a humming coming from the suspension. Unable to identify the issue. When wheels get straight the humming goes away.

As of [xxx] , I witnessed a squealing sound coming from the rear end of my 2018 denali Yukon xl truck. And it's affecting my braking. And it jerked when I changed my gears on my truck . And there are lights on in my dashboard on my truck. The engine light was blinking on and off and the traction control light was blinking on and off also. But the back driver side of the truck was squealing also. Please help me to resolve this situation. In the name of jesus. Thanks again [xxx] and [xxx] .

12/16/25 (evening): warnings began cycling across the screen: 1) service esc, 2) vehicle leveling for stability, 3) rear axel system off, 4) engine symbol began flashing, and 5) service traction control. I felt vibration/bouncing while driving as well. 12/17/25 9 took 2021 GMC Yukon denali to GMC dealership. They ran a computer scan and reported a misfire, but nothing else appeared to be wrong. They told me that sometimes a low battery can cause the warning lights and messages to cycle. They recommended that I keep driving it and return if the warnings appeared again. 12/17/25 9:18 I left the dealership. I drove 4. 5 miles, and all the same warning lights came back on. When I pulled into a parking lot, it smelled like my engine was on fire, and dark smoke was coming from my rear exhaust pipe. I called a flatbed tow truck and had the car returned to the dealership. Mileage: 52,285 GMC 2021yukon denali xl 6. 2l v8 engine well-maintained with regular oil changes. The dealership told me there was a lifter failure and that the engine could be damaged and would need to be replaced if the cam, pushrods, etc. , were damaged. They also told me I was out of warranty by less than 60 days. The dealership said my warranty expired in October 2025, even though my vehicle is a 2021 with only 52,285 miles. They just informed me that the left lifter was replaced at 6,000 miles and that they will replace the right lifter. I am concerned about further damage down the road, given the recalls on the GMC 6. 2l engines.

I am filing this complaint regarding a serious and ongoing safety issue with my GMC Yukon denali that began with a complete engine failure while driving on the highway with my entire family in the vehicle. While driving at highway speed (about 60–70 mph), the vehicle suddenly lost power and shifted into neutral on its own. While still moving, I tried multiple times to shift back into drive so I could safely get off the road, but it would not engage. I was only able to coast partially onto the shoulder before the vehicle came to a complete stop, still partly exposed to traffic. The engine shut off and would not restart at all. It would not go into drive or neutral, and the vehicle was completely dead. And it had to be towed. The dealer later told me the engine had failed and that a new engine was installed. About a week later, I picked the vehicle up. Less than 20 minutes after leaving the dealership and getting back on the highway, smoke started coming from the vehicle and warnings appeared, messages that the engine was overheating and that I needed to stop the engine immediately. The vehicle was not drivable again and had to be towed back. I again had to arrange transportation home. A few days later, I picked the vehicle up again. Since then, I have had serious four-wheel-drive and drivetrain issues. The vehicle became stuck in 4 low and I could not get it out for over a day. When it finally came out, the drive mode buttons stopped working correctly. Selecting 2 high sometimes puts it into 4 high, selecting auto puts it into 2 high, and auto mode no longer appears. Even when it shows 4 high, the steering is restricted cannot steer 100% to the right or left and the vehicle binds, pops, and jumps when turning. I believe this vehicle is unsafe and poses a serious risk.

Air conditioner condenser faulty and had to repaired. Premium ride shocks faulty and had to be repaired. Lifters and bent pushrod faulty and had to be repaired. Vehicle currently has approximately 70,000 miles. These are all known issues by gm and very expensive to fix and no recalls.

This is a follow-up to two previous complaints. The first complaint was filed around 5/22/25, and the second complaint was filed around 7/08/25. The complaint is related to a 2022 GMC Yukon that we purchased new. As reported in the previous complaints, we experienced several problems with the suspension and steering of the vehicle. The SUV continues to have a knocking, cracking, snapping noise coming from the front suspension when making a right or left turn, or u-turn. The dealer has made several attempts to fix it, but continues to occur. The warning lights continue to be set on and off, but not as often. The infoentertainment system as well. One of the other reported issues was the low oil warning light coming up and thus oil consumption. The SUV was taken to the dealer on 9/11/25, and the GMC service staff reported the SUV, during the summer hot days, was 1. 9, almost two quarts. They asked to drive the SUV for an additional 2000 miles, and it was short by . 9 quart. GMC claimed it is normal, but per their recommendations on oil changes, the vehicle would be 7 quarts between oil changes unless the driver checks the level every 1500 to 2000 miles. Not only was the information misleading as they denied to perform any services, but also is a safety concern for the damages it can cause to the vehicle, especially if it goes on safety mode. Around 7/24/25, we submitted a request for a buy-back to gm, which they approved 30 days later; however, they still have not made good on the promise, and the vehicle remains with these safety, operational, and mechanical issues.

The contact owns a 2011 GMC Yukon xl. The contact stated that while attempting to refuel the vehicle at the gas station, fuel was leaking out of the fuel tank. The vehicle was towed to an independent mechanic, where the vehicle was lifted. The mechanic then informed the contact that the fuel pump was rusted and that the frame were severely rusted. The contact was informed that the frame was fractured and had holes and was being held up by the body. Additionally, the mechanic informed the contact that the alignment had failed due to the failure. The vehicle was not repaired. The used car dealer where the vehicle was purchased was notified of the failure, but no assistance was provided. The manufacturer was not notified of the failure. The failure mileage was approximately 271,000.

So the shock strut system up front has a grommet that holds it in. The repair order said they put a shock simulator in the car and it gave false reading saying it was good and it came out broke break line and caused me to jump a curve to stop the vehicle. Also now the the tail light is out and no way to repair it no one has the light. Also this car is on its third transmission.

I had a sudden catastrophic engine failure 3/13/25. I previously filled out an NHTSA report, but I would like to add to my case. My engine was towed to the dealership and replaced. 4/25/25 the check engine light started coming on intermittently again. The service suspension notification, replace the battery in your key fob notification (which was replaced in February), and the check engine light have been coming on intermittently since then. All of these things occurred prior to engine failure the first time. The dealership would not look at our vehicle again until our VIN was called for the recall. 6/22/25 the suspension sensor was replaced and the recall “test” was done. 6/27/25 the service suspension light was back flashing and gm was unable to find any codes. 6/29/25 the check engine light was flashing again. I believe my vehicle is going to have another engine failure. Gm did a multi-point “inspection” and says it is safe to drive.

On 5/22/2025, I filed a complaint with NHTSA, complaint number 11662650. In the complaint, I reported issues regarding safety concerns that began around October 2023 and were shortly after reported to GMC. Some of the reported issues were concerns with oil consumption due to warning lights coming on; parking warning sensors intermittently coming on; and what appears to be suspension issues as there continues to be a knocking, cracking, and snapping noise coming from the front suspension when making a left or right turn, along with a bumping when in motion, among other issues such as infotertainment that continues to be an issue. Recently, we took our SUV to a GMC authorized dealer since it was still under warranty and these issues continued to persist and it is getting worse. The vehicle was left around 5/28/25 and picked up on 6/17/25. However, less than a couple of weeks after, we started experiencing the same issues with the suspension as the knocking, cracking, snapping, and bumping is getting more obvious and worse, and it appears is affecting the steering and alignment of the SUV. Please update this information as there is a major concern with safety of the vehicle. Attached are some of the service records related to these issues. Should you need any additional information, please advise. Thank you.

My wife and I purchased a new 2022 Yukon around July 4, 2022. The vehicle came with a 36k or 3 years warranty. Around October 2023, we experienced several safety concern issues with the SUV and around 11/01/23, we reported these issues to a GMC dealer. Around 11/01/23, we took our SUV for service at an approved GMC dealer and reported issues with the steering suspension such as a knocking, snapping, and cracking sound when making a turn, and a bumping when making a u-turn or left turn into a parking spot. We also reported issues with the parking and key sensors. We were informed the issue was fixed and that some suspension bolts were loosed and needed to be torqued. On 1/29/24, we took the SUV back for some of these same reasons after other dealers declined to take our SUV under warranty. Once more, the issue was temporarily fixed. We have now scheduled another appointment for these same reasons of knocking, cracking, and bumping when coming from the front suspension and when making a turn or u-turn. In addition, we are now experiencing oil warning lights for a second time as oil comsumption. We believe these are serious safety issues, especially with any potential failure of the suspension under rain, fog conditions, and the lack of resolution and wonder if other similar issues have been reported or experienced by similar drivers of these vehicles. Attached find copies of the work orders. Should you need any additional information, please advise. Thank you.

Magneride defect - struts leaking !!! 85,000 miles this is unacceptable- car is dangerous- bouncing - rough ride- shaky- jerking should be a recalll! look it up online- many many complaints!.

According to dealership front and back suspension - shock &/or struts - according to all complaints online it could be the magnetic ride control- car is a danger!!!!!! this car bounces all over the place - rides rough and bumpy!!! this should not be happening at 84k miles!.

The contact owns a 2021 GMC Yukon. The contact stated that the service suspension and low oil warning lights were illuminated. The contact stated that the engine oil had leaked out of the vehicle. The contact received notification of NHTSA campaign number: 25v274000 (engine and engine cooling); however, the part to do the recall repair was not yet available. The local dealer was contacted. The vehicle was not diagnosed or repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was approximately 83,000. VIN tool confirms parts not available.

Subject: formal complaint – engine failure in 2021 GMC Yukon denali xl VIN: 1gksjkl2mr242441 defect number (gm): 11662402 gm case numbers: 9-12578008672 / 53598259 / 54106961 dear NHTSA office of defects investigation, I am writing to formally report a critical mechanical failure in my 2021 GMC Yukon denali xl, which resulted in a complete engine failure, rendering the vehicle inoperable and exposing my family to significant safety and financial risks. Despite following the recommended maintenance schedule and driving under normal conditions, the engine failed prematurely. The vehicle has been out of service for over four months, and I have yet to receive a definitive resolution or timeline from general motors. I have incurred over $13,000 in out-of-pocket costs, including towing, repair estimates, rental vehicles, and continued loan payments on a non-functional vehicle. Key details: vehicle: 2021 GMC Yukon denali xl VIN: 1gksjkl2mr242441 failure type: total engine failure requiring full rebuild or replacement time out of service: 4+ months and ongoing financial impact: $13,335. 58 in documented costs gm defect number: 11662402 (noted internally by gm) dealer(s) involved: midas auto service, beaman GMC (nashville, TN) I have made repeated efforts to escalate this through gm’s case advisors and executive team, but have received no meaningful resolution or written acknowledgment of my request for either reimbursement or a good faith vehicle buyback. Given the safety implications of such a catastrophic failure in a relatively new vehicle, I believe this may represent a broader manufacturing defect or quality control issue and warrants NHTSA investigation. I respectfully request that NHTSA: log this complaint into your safety database investigate whether similar failures have occurred in other 2021 Yukon denali xl vehicles contact gm for further information regarding this defect and associated safety risk thank you for your attention to this matter.

The rear shocks in my GMC Yukon at4 failed and began leaking and had to be replaced. This supposed to be an off-road durable suspension and the shocks are failing?.

Transmission failed on the freeway with no signs signaling issue before hand at 109,000 miles. Also lane departure does not work often. And suspension gave out at 60,000 miles.

GMC currently has bulletin out on the issue and how to fix it. Unfortunately this doesn't not fix it and I am going to have to replace my whole rear differential at only 60,500 miles. GMC is well aware of the situation and has not done a recall. The fix the bulletin proposes would not work and there was over and inch of metal shaving found. This is a huge issue in the specific vehicle and the part to replace the rear differential isn't even available (national backorder with no eta) leaving customers without a vehicle or solution for their faulty issues. GMC should be liable for their negligence and putting customers in potential harm if the vehicle is continued to be driven with a failing rear differential. The vehicle did not prompt any warning messages but the grinding sound was very loud. Bulletin no. : 21-na-028 date: January, 2023.

Noting that prior to this we only had one issue with transmission and we did the flush and it did fine for several thousand of miles. Fast forward to a few days ago. As I was driving down the highway I came to a stop at the red light. Once it was green and I pressed on the accelerator with my foot per usual. And it did not move it pushed the gas peddle and nothing at all happened. I was stuck in the highway could not move until I’m assuming the transmission finally shifted jarring my entire car and it allowed me to get to a safe place at 20 miles an hour max. Keep in mind I was in the middle of the highway not knowing what was happening. With my precious babies in the car. Thanking god we were not injured. This problem is so common and notorious among GMC Yukons 2017 year models. It’s saddening that now I have a car note on a car that will not go. Transmissions are back ordered who knows when I can have my car back this economy is horrible trying to stay afloat. And now we have a vehicle that won’t drive and no time forks of when it can drive. This needs to be addressed ASAP. Other people are dealing with the same things and GMC need to make this safety concern a thing of the past. Make a recall.

We just purchased this vehicle from winegardner GMC in prince frederick, MD. On [xxx} on our drive home from the dealership, we kept hearing a terrible screeching/ clucking noise coming from the rear when we were braking or applying any pressure to the brake pedal. We instantly contacted the dealership and they had us bring the vehicle back the next morning for them to look at and to make the repairs but unfortunate for us. They do not have the parts in stock, so we have to take it back Tuesday, October 8 , 2024 at 8am and leave it for the day. Hoping it is repaired correctly with the new parts “both rear calipers” as I left the dealership, I was approximately 10 miles away and out of no where my dash displayed “service, trailer, brakes”, constantly along with a loud dinging noise for the rest of the drive home. I contacted the dealership and spoke with the service manager and informed him of the situation. He told me it has been an ongoing issue with gm for years and it’s electrical and because we purchased a used vehicle. It’s not covered to be repaired. We would have to pay out-of-pocket for it to be fixed. This is very upsetting because we just spent $40,000 on a used low mileage Yukon denali for our family to travel in, but it’s unsafe, because it affects the traction control, and abs brake system. I would also like to note that I did not have a trailer hooked to the vehicle, so I do not understand how that service indicator would appear unless it was cleared by the dealership during maryland state inspection. We have asked them several times for a copy of the maryland state inspection they performed, and we are getting the runaround. As the purchaser of a vehicle, it is all right to have that document, showing what past and what failed maryland inspection before being resold to us.

I have a service suspension light that continues to pop up on dashboard the most important issue that needs to be addressed is the brake lights. I have previously had the passenger side brake light stop working. In order to repair this you have to order a whole new taillight. My vehicle was approximatly 6 years old when this started happening. First incident (2022 with approximately 65000 miles) yesterday, I was pulled over by a policeman and both of my brake lights are not working. We found a way to sauder (I know this is incorrect spelling) the broken metal piece back together in the taillight; however, this is not the correct way to fix the underlying problem and clearly it is only a temporary fix because the passenger side broke again in a new spot.

1. )rear brakes are not functioning properly. They still have pads but when you press down to pump the brake it fails. I was told by a mechanic that they other GMC vehicles have had recalls on this, but mine is not showing one. 2. )the suspension on this vehicle has never worked properly. It rides extremely rough. It has some special suspension in it from a shock perspective, but it feels as if it often fails. 3. ) I had to replace the torque converter in this vehicle last year, and the fluid that runs through it. Apparently this is a known issue with no recall. 4. ) the transmission slips when the vehicle shifts gears. It shifts hard. Also a known issue with no recall.

2018 Yukon denali engine failed June 2024 due to the lifter being bent. The dealership richey Cadillac in daytona beach estimated the repairs at $18,862 and were going to have my vehicle for months. I took it to my mechanic who rebuilt the engine for $7181 in 30 days. My safety was placed at risk because while driving I had to pull over since I had no control with the engine failure. There were no messages prior to the failure.

Upper arm control screw loosened up. Drilled hole on axle.

See all problems of the 2015 GMC Yukon 🔎.

Rear lower control mounts completely rusted out allowing the rear to move back and the driveshaft to come out of the transmission. Fortunately, this happened 1 block from home at a stop sign, if it occurred on a highway, it would have caused a major accident and likely injuries. Complete frame is rusted to the point of failure, heard from others that this has happened to other makes of gm products, tahoe, chevy pickup trucks. They likely all share the same frame.

I own a 2018 GMC denali, Yukon xl SUV, with 67k miles. While towing our 24’ airstream (weight 4400 lbs) the vehicle excessively bounced in the air several times on a flat pull on I-80 in northern CA. I took it to three mechanics who told me that the front magnetic and rear air shocks had all failed and were leaking oil. The best price that we could secure for replacement is $2500. Each mechanic commented about the frequency of this type of failure with GMC and stated that this should be a recall because of the risk of trailer detachment/failure. I’ve owned dozens of vehicles in my lifetime (age 57 now) and have never replaced a set of shocks before.
