ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
Start transmission was replaced by dealer at 75 miles. 2nd transmission was replaced at 175 miles transmission was humming and slipped at around 30 to35 mph this was around April of 2024 August 1 2025 while driving at 45 dash board lit up went flashing and suv slowed dramatically down to 30 mph Got to dealership and they kept the vehicle for about a week and returned it with it being supposedly fixed. About mid October while driving at 60 mph it shut down again almost causing a wreck went to 30 miles per hour again. Hurt my wife’s neck when it reduced speed so quickly. Took back to dealership and I told them this car is dangerous this was with about 20 k miles Been in shop was told it is scanning with 22 repair codes we have not had the car for 5 weeks and are trying to work with gm and dealer to get us out of it. But as of this report no progress. On interstate in city traffic this car will hurt or kill many people. I’m refusing to let my family or myself drive it. There is no warning when it will flash lights in dash and reduce speed. Also the front crash sensors went out and are currently not working we have all service records and paperwork that has been done including maintenance records We were given vehicle back with no warnings. I went to Nita’s and ran vin and it still shows issues. We are still making payments but driving a loaner car. The car is dangerous. I advised the dealer the first time it happened. I didn’t want it back. My wife went and got it and it sis it the second time and now she agrees it is dangerous contacted GM and they want to fix it but dealer implies they can’t ?..

ENGINE, FUEL/PROPULSION SYSTEM
On November 14,2025 my engine failed on the highway going 80 mph to 0 mph in the passing lane. Almost caused a major accident on US23. I’ve asked my dealership Bowman Chevrolet repeatedly to inspect my engine for the recall and have been denied every time. Most recent was October when I had my oil changed and I was told it wasn’t my turn and the recall for my vehicle was pending. I had my vehicle flatbed towed to the dealership where it sits dead in their parking lot. Thank God we didn’t die on the freeway that night. It was a horrible experience.

ENGINE
On November 5, 2025, this 2025 diesel GMC Yukon Denali brand new vehicle went into "limp mode" 75 days after purchase with 3,957 miles on the odometer. Vehicle began to decelerate on a busy road. Warning lights went on to indicate that accelerating was no longer possible. Other fast-moving vehicles on the road came very near to the Yukon and quickly passed it/weaved around it, jeopardizing the lives of this Yukon's driver and occupants. At times, the Yukon diesel vehicle would only reach 15 MPH. Vehicle eventually driven to nearest GM dealership. The GM dealership service center reported a P06D code and reported that the engine experienced catastrophic engine failure. A new diesel engine has been ordered but is not yet available to the dealership for installation. (The dealership also reports that two other new GM diesel SUVs are waiting on new engines due to catastrophic engine failure.)

SERVICE BRAKES
8/26/2025 I purchased the vehicle from Maguire in Syracuse, NY with open recalls. It is my understanding a dealership is required to have these fixed prior to selling a vehicle. I now have to drive 45 mins each way to get them fixed and miss additional 2 hours for wait time from work. Brakes could fail causing an accident.

ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS
While driving vehicle on 11/08/2025, vehicle made a popping noise and loss power. We were out of town and had to pay out of pocket to have vehicle towed to a dealership and hour away from our home. Dealership diagnosed issue with engine failure due to lifter fell and caused damage to cam shaft and bore. I will be without a vehicle for an additional 2 to 4 weeks waiting on a back ordered engine from GM, and continue making payments on vehicle as well. This issue seems to be an ongoing problem that GM is ignoring…….GM should compensate towing, car rental, and repair/ replacement charges due to failure.

ENGINE, SUSPENSION, STEERING
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.

ENGINE
On October 21, 2025, with only 4,197 miles on my Yukon, the vehicle suddenly died while in drive in a parking lot. The vehicle would not restart or shift into neutral. I contacted OnStar, who arranged for the vehicle to be towed to the nearest GMC dealership. Since that date, the vehicle has remained at the dealership and has been diagnosed as needing a complete engine replacement due to metal shavings found in the engine. There were no warning lights, messages, or performance issues prior to the failure. This incident was both unsafe and alarming, as the vehicle shut down unexpectedly without any warning while I was driving. I would like to understand how such a major failure could occur on a brand-new vehicle with so few miles.

ENGINE
The vehicle engine experienced a failure on the highway at very high speeds with no warnings leading up to this occurrence, same as many of the experiences of the customers with the 6.2L engines, which have been recalled for these defects. This GMC Yukon has the 5.3L engine, however, has the same defects as the 6.2L engine, excessive oil consumption and eventually engine failure. I am without a vehicle, with an extremely high car loan, and have to replace an engine in a two year old $75,000 vehicle. This should be covered by GM as it was a known issue and continues to be sold to unknowing customers. Furthermore, I am paying even more money to put another engine in this vehicle with the potential of having the same issues as the problem has not been corrected. This is deceptive and theft by GM in my opinion, and not safe to have engines failing in the highway with no warnings at all.

SEATS
After GMC completed 4 recalls recently, my drivers side seat lumbar support started automatically inflating to the highest setting, as well as the shoulder support. I could not deflate the shoulder support at all, but could deflate the lumbar support, but had to do it every single time I got in the vehicle. After they did additional recalls about 30 days later, the issue got worse and often times I'm unable to deflate the lumbar support at all, making driving extremely uncomfortable and what I would deem slightly unsafe given how inflated the seat is. The fact that the 2nd set of recalls made this situation worse makes me suspect it's related to module updates as opposed to my particular seat. Now I am on the hook for a $1200 fix. 2 different GMC locations did the recalls.....I do not blame either of them, I believe this is a defect GMC should look into asap given they have had similar seat issues in the past.

ENGINE
I was driving down 85 South bound at mile marker 16 the engine started messing up causing me and my family to be pushed over to the median. Once I was able to fight it over to the median it started smoking and i was afraid it was going to catch fire, so me and my family had to get out on the side of the interstate until help showed up and said it was safe to get back into the car. I had to use OnStar to get a tow truck, after the tow truck got there and i made it to the closest dealership to find out that the so called recall that the GM dealership fixed did not help the fact that the engine was messed up. So i tried to get a loaner or rental car for my family of 6 and they rented me a small SUV that I can not get all my kids into, I was told they did not have anything that bigger so now I am having to make multiple trips getting my kids to school. Plus they are saying it is going to be months before I can get my car back because the engine is on back order.

ENGINE, ELECTRICAL SYSTEM, STEERING
I’m not happy with just a change in oil viscosity because the car has already been on the road for 70000 miles before we were aware of the recall on the engine. Changing the oil viscosity doesn’t help when there is a underlying engine problem it should be replaced not just change your oil and send you on your way because now I’m always wondering and worried if the engine will still fail when my kids and wife are in the car. Furthermore I just had it inspected and the oil changed to new viscosity a week ago and the oil level is already half way on the dipstick so I’m taking back to the dealership to express my concern. If I would have known this was going to be an issue with this suv I would have purchased something else. I’d just like the engine replaced so that I don’t have to worry every time I pull out of the driveway with my family. My power steering assist still whines and there is no open recall on it. I think GMC should be responsible for replacing engines and power steering assembly and power steering motors on 2021 GMC YUKON DENALIS because of the wear and tear they have endured before the recall was taken care of by adding a different viscosity oil because the damage has already been done.

ELECTRICAL SYSTEM
I'm reaching out because I've encountered a really concerning issue with my 2025 GMC Yukon AT4 Ultimate. There's a really loud popping noise randomly coming from the speakers that's honestly quite startling and dangerous while driving. Most recently, it scared me so much that I swerved off the road and nearly crashed. If you review online forums, you will find that this has been experienced by other owners as well. I've tried to resolve this through your usual service channels, but my concerns have been dismissed without any recommended action to ensure my family's safety. After scheduling with my local GMC dealership they couldn't replicate the noise and sent me on my way. I also brought it up with GMC Customer Care, and they suggested I try to record the sound, or keep bringing it in for service if it happens again. The problem is if I tell them it keeps happening again, what good will it do? It's a loud pop coming from the back speaker area. Even if they had 7 technicians hearing it at the same time, how will that make a difference. I need them to start testing components and replacing them one by one until its resolved.

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
Driving through the intersection of N. Scottsdale Road and E. Bell Road in Scottsdale AZ my collision warning red light flashed on the screen and the engine turned off. This caused me to lose forward propulsion and forced me to navigate to the side of the road to avoid being hit by another car. At Van’s GMC, the service manager told me that we experienced a catastrophic engine failure and that the engine seized. Vehicle has been inspected, but I have not received an official diagnostic even though I have requested. There were no warnings or indications that the vehicle was compromised prior to the engine turning off.
