POWER TRAIN
On April 30, 2025, my 2023 GMC Yukon with 68,000 miles on it (8,000 miles outside of the warranty and that I had purchased on 4/27/2024) randomly downshifted as I was turning into a parking lot and gave me a computer notification stating "Service transmission now, unable to shift soon." I immediately put my car in park and called OnStar for her to read me the computer code. She said it came up with two codes so we brought it to Wyatt Johnson GMC in Clarksville Tennessee. They plugged in their computer reader and that's when the service provider informed me that my car was un-drivable because it was unsafe. We left it there for them to do a diagnostic test on it to see exactly what is wrong with it. A few days later they contacted us and informed us that it was a malfunction in the transmission valve body. The dealership informed us that it would cost $2754.25 to fix but the issue is the part is on back order and they don't know when it will be available. We have been in contact with the dealership and with General Motors customer service almost weekly trying to find out, when the part will be available and where I am on "the list" and no one has an answer. With the personal research that I have done, I have seen that people have been waiting for over a year. I also know that there are current class-action lawsuits for GM's Yukons for years a little older than mine and currently multiple complaints for the newer Yukons for the same transmission valve body issues. The dealership does not give out loaners anymore after Covid. I have asked, general motors. Customer service has informed me that it's up to the dealership if they will give me one General Motors said they would look into a possible reimbursement program if I have to purchase a rental, but they will only cover a car that cost $44 a day and that is not including taxes and extra fees, but I can't afford to rent anything and I'm missing work.

POWER TRAIN
The transmission failed at 59,700 miles. The transmission will shift up and down by itself. The transmission is revving up when trying to pass and the vehicle will go limp for a few seconds and then the gear with kick in really hard. In stop and go traffic the transmission slips constantly and could cause an accident due to the limp mode.

POWER TRAIN, UNKNOWN OR OTHER
The engine and transmission shakes and they say all this normal. Vibration occurs throughout vehicle at idle or driving at any speed. Also, rpm hand slightly moves up and down while idling in park. The vibration is more prominent in 2 and 3 row seats. I have taken it in about 7 or 8 times for the same issue to 4 different dealerships. Only one has actually felt the issue and visually saw the vibration/hop in rear of vehicle. The technician could not determine the problem as GM only allowed a visual inspection. He was not allowed to take anything apart so I am still left with the issue and it is getting worse. In addition, vehicle taken to collision shop to inspect frame, vehicle was within spec. Vehicle is now back at another dealership to address the issue. The only thing that all the dealerships have done is road force balance tires, alignment, and changed out driveshaft axle from a prior recall. I paid to have to have a differential fluid change still has vibration. At this point, it is concerning because as I stated the problem is getting worse. Also, dealers are looking for a computerized answer and I dont think a powertrain issue will be diagnosed this way. My truck should be under recalls but none has applied to it.

The information screen on the gauge cluster sometimes will stop working. This is dangerous as It is the only part that shows if the vehicle is in Park, Reverse, Nuetral, or drive. It also is the only part that shows the vehicles fuel level, blinker, cruise control, temperature and other warnings and controls. This is a common problem for the 2015- xxxx Yukon and Tahoe.

ENGINE, UNKNOWN OR OTHER
On 05.29.25 my 2021 GMC Yukon Denali with 24,000 experienced engine issues and ultimately a total failure. While driving at 65 miles an hour the engine light began blinking and a thumping/knocking noise began on the front passenger side of the vehicle. I was 1 mile away from the GM dealership and went there immediately. They called me two hours later confirming the engine failure and that it would have to be replaced. They stated, however, the engine is experiencing a national backorder. No timeline has been provided for the engine to be received or replaced. I am curious to know if the new engine will come from the same engine group that is currently having issues, and if this can happen again.

I am filing a complaint regarding my 2023 GMC Yukon Denali Ultimate, equipped with the 6.2L L87 V8 engine, which is currently under NHTSA Recall 24V-266 for a potential engine failure due to defective bottom-end components. I received the official recall notice indicating that the issue poses a serious safety risk, including possible loss of propulsion and engine failure without warning. However, despite this being a mandatory safety recall, I’ve been informed by my dealership that no remedy is currently available, and I have been provided no timeline for repair or inspection. This effectively renders my $115,000 vehicle unsafe for normal use, yet I am left with no clear recourse, no loaner vehicle, and no repair timeline. I am now forced to restrict my driving to short errands only to reduce risk—completely unacceptable for a vehicle of this cost, class, and usage expectation. I am requesting that NHTSA formally investigate the timeliness and adequacy of GM's response to this recall and consider enforcing provisions of the Motor Vehicle Safety Act that require manufacturers to remedy defects within a reasonable timeframe. Thousands of affected owners are currently left without a fix for a potentially dangerous engine flaw. Vehicle: 2023 GMC Yukon Denali Ultimate Mileage: ~28,000 miles VIN: [XXX] Recall #: 24V-266 (GM internal reference N232414720) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The #3 lifter on my cars engine failed with 80101 miles on it. The engine started to run weak by shuttering. My wife was driving and the car was shaking at a stop and vibrated upon acceleration. I took the car to the dealer and they said the #3 lifter collapsed and could have caused engine failure. The dealer replaced the lifters on that side of the engine.
