ENGINE
At approximately 14,000 miles my 6.2L V8 engine had a lifter go bad on the truck. GMC covered this with warranty at the time. The truck seemed to perform well until I hit approximately 94,841 miles and then a lifter went bad again. I had an 85,000 warranty and this repair was not covered. I was quoted $6,500 to repair the truck by the dealer. I made a social media post and tagged GMC. GMC reached out to me directly and took $1,000 off of the repair and I paid $5,576.48 out of pocket to repair the lifters. GMC also offered an extended 2 year warranty on the engine at that point that is expires in September of 2025. I currently have 143,000 miles on the truck and my intent was to drive this truck for as long as humanly possible. I was told that this was designed to be a 500,000 mile truck. My engine is now burning approximately 2.5 to 3.5 quarts of oil between oil changes and I'm worried that there is something else wrong with the engine and that another lifter will go bad. I love my truck and can't afford another $6,500 to $10,000 repair. I sometimes get this car and other cars serviced for an oil change at the Mavis Auto in my neighborhood and the shop director who has been in the business has a friend who is a mechanic with GMC and he told me that his friend was given directive that if one lifter went bad 100% of the lifters, the housing and CAM shafts were to be replaced. (I'm not a mechanic so I may be missing some details here) Anyway - I've been informed about the NHTSA Investigation Into the V8 Engine in my truck which has opened my eyes to other mechanical defects associated with my truck. I'd like to make this report to protect myself and my investment. I do not want incur additional expenses related to manufacturer defects and I do not want to feel unsafe on the road with this vehicle.

ENGINE
Engine failed at 20,100 miles. Going 65 on the highway in rural area when the lifters failed and it decelerated quickly. Had it towed to Monken GMC and they stated the engine had an 11 month lead time for replacement due to the high number of I87 failures that GM is currently having. Eventually had it towed to O’ Fallon Buick GMC in the St. Louis area, where they confirmed the same thing. Engine failure, 11 month wait time. I called GM and they offered no assistance.

BACK OVER PREVENTION: WARNINGS, LANE DEPARTURE: BLIND SPOT DETECTION, FORWARD COLLISION AVOIDANCE: WARNINGS
My vehicle has software that controls the rear gate, cameras, and my safety features for blind spots—seat buzzer to warn of collisions and voice activated phone system. I recently had a safety recall involving my back wheels locking up during driving. I had the recall done by Power Chevrolet and it affected my cameras, which I noticed were longer accurate immediately after leaving the dealership. My seat buzzer kept buzzing warning me of a collision due to the cameras inaccuracy. I am unsure if it affected my blind spot warning but my car was unsafe to drive as the safety features fill in many blind spots in this big vehicle. Additionally I had been having issues with my back gate opening when it should not resulting in two stops to close it— one in Costco and one on [XXX] outside of Philomath, Oregon. These are safety issues. To get the software issues resolved, it cost an additional $210 for the updates and my back gate is still not fixed and no solution is offered. My fear is that people will be unaware their cameras or safety features are no longer properly calibrated and hit something or even worse, be unable to pay for software updates to make these features functional resulting in more crashes. I was unaware of the software updates ( I did all updates GMC pushed) needed to be done and this just continues on with more software updates to be released requiring future payments. I bought this car new and this was not disclosed or even discussed. GMC can push down updates that make other updates necessary and be an unending source of revenue for them. Oregon just passed a right to repair law but cars are exempt. This will result in unsafe vehicles on the road. My oil change cost me $350 with $210 the software updates. What were these safety related updates not done as recalls? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
The complete engine on this vehicle was replaced by GM on 04/05/2024 at 24,069 miles. This was due to the known engine failures GM is having with the 6.2L engine. This is a well known and documented safety issue that GM is refusing to properly address. Vehicles with the 6.2L L87 engine are having complete engine failures while driving at highway speeds, which is a huge safety issue. I live in north Georgia where the roads are steep with sharp blind curves. I frequently cross steep mountains with high elevations that require frequent brake usage and constant steering through the sharp curves. I also drive on the interstate in Atlanta, GA where the posted speed limit is 70MPH. An engine failure in any of my driving circumstances is life threatening. As you know, when the engine fails you're braking and steering capabilities are greatly reduced. For example, if I was to experience an engine failure while driving across the mountain I would be unable to stop or get the vehicle off the road. Without being able to move, I could be stranded in a blind curve where I could be struck by another vehicle. I do not feel safe driving this vehicle and I'm in constant fear that it will have another engine failure like so many other 6.2L owners are experiencing. I'm morally unable to sell this vehicle to someone else due to the known engine failures. GM will not take responsibility and fix the issue or buy it back. So, I'm stuck with a $90,000 SUV that is unsafe to drive. Please continue to investigate this safety issue! You are saving lives by doing so. Thank you for everything you have done and are continuing to do. Please let me know if you need additional information or I can be of assistance.

Not even 100,000 miles on it and the engine blew. Started with a lifter issue. Everyone I talk to with Yukons and GMC in general say it’s a problem. Just a search on the internet shows that they all have this issue… a well maintained car should not have this issue and it’s clearly a GMC issue and it needs to be fixed. The repair shop can’t even order me a new engine due to this being a real problem all over with GMC.

POWER TRAIN, WHEELS, FORWARD COLLISION AVOIDANCE: WARNINGS
Upon cold start vehicle rattles when idling down and growling noise when accelerating upon left or right turns. Also, has constant vibrations with sound of metal rattling at speeds above 30 mph. Forward collision light on without a significant amount of mileage on vehicle. I have taken my vehicle to dealership at least 5 times referencing the vibrations. Growling noise was heard by service advisor last visit October 2024, and he stated it probably were the tires. I advised him that brand new tires were put on vehicle, April 18th 2024, rear vibration has never stopped from time of purchase. I have asked dealership to check drivetrain as it is a know issue for 21 Yukon Denali. Vehicle has not received recall but was manufactured at Arlington plant where the parts of the drive shaft was not properly heated and differential is known for issue upon cold start. Vehicle powertrain warranty is due to expire August 2025 or 60,045 mileage. Therefore with that, the vehicle was placed in service August 2020 months before unproperly heated driveshaft recall was determined. My vehicle should be on the list for this recall as GMC noted this to have occurred on vehicle prior to 07/2021. In addition, a chirping noise comes from front of vehicle while idling and when automatic stop starts back up.There are already known recalls for two of issues noted above.

Was driving on the interstate when the engine stopped running. My screens went off and came on saying to press the start button to turn on as my car is still moving. Once pulled over couldn’t get the car to turn off or shift out of park. Engine never started since then. Mechanics looking at the Yukon have verified that my engine did seize up. My car is less than a year old.

Blown motor on 2023 Yukon (after owning the SUV exactly 1 month). 3600 miles on it. Picked it up January 9, 2023, motor blown on Feb 9th, 2023. From my dealer: Tech found perform tear down on the engine- remove lower oil pan and discovery metal inside the oil pan. perform inspect on the bottom engine and found rod bearings spun- causing internal premature engine failure. Final ticket write up included: engine appeared to be “starving for oil” cylinders #5 & 6 piston rod bearings seized. Major internal engine failure. I went through the full engine replacement at a local dealer then dealt with GM for 2 months and eventually they did fully replace this vehicle with a new 2023 GMC YUKON. Luckily expedited the build as the first one took 9 months to receive. we took deliver of new vehicle in June of 2023. Can provide the new VIN if necessary. Current 6.2L has about 30k miles on it .

ENGINE, POWER TRAIN
The motor on my 2021 Yukon completely failed while driving on a busy state road. The blown motor was replaced by a local GMC dealership, so I do not know it's status or if it'd be available to inspect. My safety was greatly put at risk. I am blessed that my wife and children were not with me, if they were, I would be even more furious. While driving on a busy state road, the tachometer dropped to zero and the truck automatically shifted into neutral. I quickly realized the engine had shutdown, and attempted a restart while coasting. The motor would not restart and I was lucky enough to coast into a nearby parking lot. Had I been in traffic, on the highway, or at a stop light, the situation could have been even more dangerous. As it was, I was stuck in below freezing temps for several hours waiting for triple A. They sent the wrong tow truck twice, and I eventually cancelled the triple A call and called a local wrecking company to come tow the car more than 24 hours later...luckily in the interim I was picked up by a family member. The issue was simply stated to me by the mechanics at the local GMC shop as the motor had "blown", they didn't know why, and they completely minimized the magnitude of the situation. To the best of my knowledge the blown engine has only been looked at by GMC employees. There were NO warning lamps or other symptoms associated with any such failure of this type - which in my opinion, makes the matter even worse and more dangerous. I am frankly furious that GMC is not doing more to address these known catastrophic issues. They have said they will not extend the powertrain warranty and I've read online that people have had their "new" motors blow the same way that the old ones did.

The engine turned off while driving TWICE with NO WARNING. The first time the engine turned off without warning doing around 60MPH but was able to be restarted and ran normally for about a week or so. The second and final time that the engine turned off without warning was about a week after the first incident. The engine would not restart, in fact, it would not even crank. The vehicle was towed to the dealership where it was determined to be a crankshaft bearing failure causing a bottom end engine failure. Metal shavings were found in the oil pan. Vehicle is only 14 months old and has 22,754 miles. All service was done by dealer at manufacturers suggested intervals.

ENGINE, SERVICE BRAKES, VEHICLE SPEED CONTROL
[XXX] while driving on [XXX] myself and my family in our 2022 yukon 6 lane highway 65 mph the engine lost power with no warning at all and left us with no power steering ,or brakes. This was in heavy traffic with other vehicles on our right and left side. I was able to put 4 way on and carefully move to the right lane and then barely to the burm. Vehicle would not restart and the sound of it was of rattle and groan. yukon was towed to the nearest dealer and we were told it was a bad engine of either bearings or rods. We were very lucky to not having an accident and harm my family or other persons on the highway. When a new engine was installed it ran for ony 15 minutes and also was defective for the same issue. Vehicle was returned to us on 12/14/24 and we were denied any additional warranty. At this point i have no confidence in the vehicle or General Motors. We took a financial loss when we traded the vehicle because of the major problems thru no fault of ours. The dealer would offer nothing as far as extending the warranty nor would GMC customer service that we filed a formal complaint # [XXX].

Passing a semi up a hill going 75 and the motor shuts off. As the Yukon slowed, the semi slowed down as well. It was difficult trying to get the Yukon to the right shoulder. There was no warnings or anything on the dash. The vehicle just quit running. Tried restarting and it was like the battery was dead. Got it towed to a dealership and they said the engine was ruined from 6 of the 8 rod bearings disintegrating. Took almost a month to replace with the problem being so common and no engines available.

ENGINE, FUEL/PROPULSION SYSTEM
My 2021 Yukon Denali has roughly 70k miles and this is now the SECOND time that my engine shut off while driving >55mph on the interstate in the past 3 months. The first time, I had the sensation that the car was running out of gas when I went to accelerate. After about 5-10 seconds, the engine turned off, but the electronics stayed on. I coasted to the side of the road and tried multiple times to start it without success. The engine sounded fine while turning over and over, but it would never start. That episode turned out to be a bad fuel pump control module, and after roughly $400 at the local Firestone auto repair shop, I was on my way (FYI, they didn't diagnose it; I learned that was the likely problem by reading online forums and basically demanded they replace the FPCM). Now, here I am about 3 months later, and it happened again, just two days after I had the vehicle serviced at the GMC dealership for a check engine light that was intermittently coming on. The technicians said I needed an update to the Engine Control Module which was completed. The main difference was that this time, I had zero warning. There was no sensation of running out of fuel or funny noises from the engine. I just went to give it gas and noticed it wasn't working. There was a warning on the dash saying push button to start the vehicle (once again, the electronics stayed on when the engine shut off). After coasting to the side of the road, the battery seemed to be good, but the engine wouldn't turn over. I had it towed to the shop and am being told I will likely need a new engine!

Was driving on highway when the engine started to labor. Without notice the car flipped into neutral. Obviously this was very dangerous going from acceleration to no engine power. I barely made it to the side of the highway by crossing two lanes to get there. When on the side of the road the car went into park and was unable to move to any other modes. Not even neutral. Again very lucky to have gotten off on the shoulder. Once the car came to a stop we were stuck for good. Had to get towed 60 miles or the nearest dealership with my wife and two young children. Took the car to a GMC dealership who said; “yeah this has been happening with the V8s”. It has now been 30 days and still no updates from GM outside of them waiting on a new engine. Also GM only gives you $44/day for a rental car which doesn’t even come close to covering a like kind vehicle. We had a 2024 Yukon Denali. I am now without a car and the only communication I am getting from GM and the GMC dealership is to wait until they receive and replace the engine, which they say should hopefully fix the problem. I am not taking the risk that this could happen again with my family in the car. Looking to get some form of a buyout and move into a different car.
