ENGINE
i was with my entire family 3 hours from home on a ski trip loaded with gear and the motor decided to go. i had to pull into an abandoned lot, leave my family in a car with no heat, walk 6 miles up a mountain to get another vehicle and pick up the family. Then i had to call a local tow company to drive out pick up the vehicle and myself and drive 3 hours home drop the vehicle at the dealer and then myself at home. The vehicle was not even pulled in for 2 weeks to be looked at (no other vehicle was available) and then they told us the motor was shot - lifters cam and other things and that the head gasket was on back order indefinitly. This happened the beginning of February its now March 6, the vehicle is in pieces at the dealer with no time frame of when we can get it back. Meanwhile its costing me 1670$/ mo plus insurance. For a 100k$ vehicle to go with 30k miles is wildly unacceptable. I have had no luck getting a return call from a representative with GM which is why i am filing this complaint now.

ENGINE, UNKNOWN OR OTHER
My vehicle started making a terrible noise. I had it towed to the nearest GM service center. It was determined that the vehicle, a 2023 Yukon Denali (less than 26000 miles) needed a new engine due to thrust bearing failure causing the engine block to be scored and contamination of debris internally.

The contact owns a 2023 GMC Yukon. The contact stated while her husband was driving at 75 MPH, the vehicle independently accelerated without depressing the accelerator pedal. The check engine warning light was illuminated. The contact stated that the transmission started to downshift, and the vehicle started losing motive power. The contact's husband merged to the side of the road and turned off the vehicle. While the vehicle was off, the message to press enter to start the vehicle was displayed; however, the vehicle failed to restart. The vehicle was then towed to a dealer and diagnosed with total engine failure. The local dealer was contacted; however, the vehicle was not repaired because the vehicle was not under recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 34,000.

On Friday 2/21/25, while driving on the Interstate at Highway speeds, the dashboard said to idle the engine. The engine then stalled and thankfully I had enough speed and there was a shoulder available to pull off on. The dashboard then gave many messages including voltage, overheating, high oil temperature, idle engine, etc... I was unable to restart the vehicle on the side of the interstate. I was towed to the dealer who advised the engine would have to be replaced. This vehicle has a 6.2L gas engine with 39,223 (approx) miles.

I was driving home from work at around 60 mph. Very sunddly their was a rattling metal sounds and then vehicle struggled to maintain speed. Before pulling off the highway at the next exit. On the exit ramp the engine turned off and would not turn back on. The vehicle was also stuck in neutral and not able to shift out of neutral for towing. There was no worning lamps or messages even after the noise and reduced power. Vehicle was towed to local dealership on Tuesday evening, as this was not scheduled it took them to diagnosis the issue as engine failure and recommending to replace the engine. The vehicle is a 6.2L GMC Yukon Denali with 23k miles. All service has been done at the dealer with no outstanding work prior to the engine failure. Where it gets more disappointing is the lack of information for time to fix. The replacement engine was ordered by the dealer on February 14th. As of February 28th they did not have any information....So i called GMC on that 1800 number listed on GM Document DCS6866 referencing customer satisfaction program N232413430. The first agent disconnected without filing a case. The second agent had to restart the process and was told that there was nothing they would do for 14 days after the case was opened before it would be elevated. When talking to the agent they denied any information related to the GM Customer Satisfaction Program or any knowledge of what seems to be a wide spread defect on 6.2L engines. The service and support for a $90k vehicle from, in fairness they have provided access to rental vehicle from a local auto shop. The vehicle is far smaller and different from our vehicle we purchased. The vehicle is still sitting at the dealership service center and is not functional until the engine is repalced.

While we were driving at a high speed all control of the vehicle shut down. There was absolutely no warning that this was going to happen to that anything in the vehicle was breaking down. We were able to get to the side of the road and the vehicle locked into N. From that point on the car did not work. After being looked at my GMC, they decided that it needs a new engine. It only has under 15K miles. We were told that some somehow pieces of metal were in the engine. Engines are currently on a national backorder and we have been without our vehicle for over 4 weeks. They have no expected date that this will be fixed.

On [XXX], at approximately [XXX]., I was driving down a highway and my vehicle engine just stopped. The dash went blank, I lost power and steering and there was no warning. I had enough momentum to partially stop on the shoulder of the highway but part of the vehicle was still in the flow of traffic. It was a dangerous situation for sure, especially since I had my [XXX] son in the car with me. I had the vehicle towed to the dealership where I purchased it, they said it was a connecting rod failure and I would need a new engine. This was on [XXX] and I still do not have my vehicle, they said the engine was on backorder. I have been in regular contact with GMC customer service and they have been largely unhelpful and unwilling to explore any other option that me just waiting for an engine to come it. I am now in my 9th week without my vehicle. The way they have treated me is unacceptable and they have not even acknowledged the danger that this defect put me and my son.

On Jan. 19, 2025, while driving home, I started hearing a loud knocking noise from my engine. Lucky I was still on residential streets so I was able to safely pull over to a parking lot. I was planning to drive the 40 miles home on the freeway when my wife said it might not be safe. That was when I decided to drive to my sister's house. Only when I pulled into the drive way the check engine light finally came on. The next day, I had the vehicle towed to the dealership and they diagnosed that I needed a new engine. They did not go into specifics as to why I will need a whole new engine but they did tell me that this was common and that they had other vehicles waiting for an engine also. My vehicle has been sitting there since.

Traveling at 65 MPH on highway when electronic dash went completely blank, audio on car stopped as did the engine! Steering of vehicle remained in tact so I was fortunate to be able to "coast" to the side of the highway. GMC Dealer has confirmed a total engine failure and stated they will need to replace the entire engine. There were no prior warnings, symptoms or problems with my vehicle prior to this incident.

Our Yukon Denali at around 34k miles lost power while in motion, it automatically put it in neutral and said try to restart. Rolled to a stop in a turn lane and when we tried to start ignition…nothing happened. On star was called and ran diagnostic, showing no issue. Towed vehicle to dealership and the engine seized up. 4 piston rods had broke and the engine needed to be rebuilt.

My vehicle was being driven by my Nanny and had my children in the car, the engine started making a strange noise so she was required to pull over on a busy highway bridge in Tulsa, OK. There was no warning of any issues with the vehicle before this incident. It then would not start and had to be towed to a GMC Dealership in Broken Arrow, OK. They informed me the entire engine is locked up and has to be rebuilt.
