Defect Description:

ENGINE

Potential Consequences:

Was going up a hill and all of the sudden the engine stopped, the truck coasted to the edge of the road. A message came on saying 'Press start to reset engine.' Doing so did nothing. The truck ended up having to be towed to a dealer. They were not able to turn the engine over by hand and ended up diagnosing the engine as a seized from a failed bearing. They ended up replacing the entire engine with a new identical one. They have not been able to tell me if the new engine is in the same engine group that I could experience the same thing a second time.

ENGINE

Potential Consequences:

While towing my boat to the Florida Keys, I encountered a series of mechanical issues on Interstate 75. The engine’s exhaust became excessively loud, causing the engine to abruptly shut off. Despite successfully maneuvering into the safety lane, I was unable to restart the engine. I promptly contacted the dealership, which dispatched a tow truck to my location. However, the tow truck driver was unable to put the vehicle in neutral gear. Subsequently, I reached out to GMC, which informed me that the tow truck required a flatbed for transportation. I waited another two hours for a flatbed truck to tow the vehicle to the dealership. A few days later, I received notification that my engine had seized, necessitating an engine replacement. The dealership informed me that the 6.2-liter engine was experiencing a national backorder. I had purchased this used vehicle less than a month prior and had not yet made my initial payment. Consequently, I find myself without a vehicle. The dealership has been unable to provide an accurate timeline for the repair to be completed.

POWER TRAIN

Potential Consequences:

My wife and I were traveling westbound on [XXX] just outside of Durkee Oregon, when while going up a hill with Cruse set to 72, the truck began to slow down drastically. When I looked down I was then going 60 and showing down fast. I was able to get to the side of the road and then the truck stopped, it shut off. At that point the truck has not be back on. It would not turn on and Onstar reported that there is an issue with the Engine and transmission. No warning lights came on until we stopped. Then the Engine light was on and the truck said that it was overheating but the oil temps were normal. I feel lucky that there was not much traffic. My wife and I were on the side of the road for 2 hours at dusk and in the dark with 65+ MPH traffic zooming by. Also had a impossible time tracking down a rental call just to continue to my wife's grandmother's funeral service. I just talked with the dealer and they will not have a diagnoses for me until late tomorrow. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE AND ENGINE COOLING

Potential Consequences:

The contact owns a 2023 GMC Sierra 1500. The contact stated while driving at various speeds, the vehicle experienced a loss of motive power. The contact shifted to neutral(N) and was able to restart the vehicle. Additionally, the contact stated that while driving 55 MPH and pulling an unloaded trailer, the vehicle suddenly stalled. A message advising the contact to shift to neutral(N) and to attempt to start the vehicle was displayed; however, the vehicle failed to restart as intended. The contact was still able to use the power brakes and the power steering, which allowed the contact to pull over in a safe area. The vehicle was towed to the dealer, where it was diagnosed that the presence of copper filings in the oil had caused the engine to run roughly. The dealer determined that the engine needed to be replaced; however, the part was not available. Additionally, the average waiting period for an engine was approximately 6 months. The vehicle was not repaired. The manufacturer was informed of the failure and a case was filed. The failure mileage was 33,000.

A message advising the contact to shift to neutral(N) and to attempt to start the vehicle was displayed; however, the vehicle failed to restart as intended. The contact was still able to use the power brakes and the power steering, which allowed the contact to pull over in a safe area. The vehicle was towed to the dealer, where it was diagnosed that the presence of copper filings in the oil had caused the engine to run roughly. The dealer determined that the engine needed to be replaced; however, the part was not available. Additionally, the average waiting period for an engine was approximately 6 months. The vehicle was not repaired. The manufacturer was informed of the failure and a case was filed. The failure mileage was 33,000.

Defect Description:

POWER TRAIN

Potential Consequences:

The system that is not working properly is the transmission. It is available for inspection upon request. The safety of the vehicle, and myself, was put at risk because the transmission (once warmed up / at least 30-60 minutes of driving takes place) downshifts hard, making a clunking noise, and has at worst given the vehicle a rough nudge/jolt forward upon downshifting particularly from 2nd to 1st gear (it is a 10 speed transmission). This issue, when it occurs, will require me (the driver) to apply extra force to the brake pedal due to the rough downshift / jolt upon shift. The issue is exacerbated when quickly stopping the vehicle causing the transmission to downshift more rapidly. The vehicle's transmission flaws, of which this happens to be one of them, were being looked into at a certified repair facility (dealership). After the vehicle was in their possession 3 days, they informed me that they could not replicated or reproduce the issue. I informed and reminded the following: (1) the vehicle has to be warm and operated for I would state at least 30-60 minutes of driving before the issue arises (2) I have recorded videos of the problematic sounds of the transmission. (3) I am willing to go for a test drive to try to replicate the issue with dealership staff, but the issue is infrequent and the vehicle must be warmed-up and/or driven more than the typical "test drive" for the issue to be observed. The vehicle component has been inspected by a certified repair facility (dealership), but not directly by a manufacturer's direct representative, police, insurance representatives, or others. The transmission is also problematic in another way (rattling at low rpm's during upshift), but pertaining to safety the downshift is most concerning as described above. There were/are no warning lamps or messages. The symptoms of the problem pertaining to the transmission began occurring around 11,800-12,000 miles in my estimation.

ENGINE

Potential Consequences:

I was driving on the interstate when my vehicle’s display indicated that I needed to press start and that is when I noticed the engine was not running. I had to quickly pull over moving three car lanes all while coasting and I came to a stop. I tried multiple times to restart but the engine would not restart. I still had electrical power and turned on my hazard lights and called for a tow truck.

POWER TRAIN

Potential Consequences:

Rear axle locked up driving down the interstate at 65mph. Had I been towing, the incident could very well have caused an accident. Truck taken to dealer and was inspected. Gave an error code of P0747. Per the dealer it was caused by a faulty valve body in the transmission. Part is on back order for months to get fixed. Truck is not drivable as it will not go out of 5th gear. Was told that the problem was found in many models from 2020-2024.

ENGINE

Potential Consequences:

Driving at night on non-marked rural road at approximately 40 mph when the motor quit. I was going slight downslope and didn’t know until the Push button to start message came up. I coasted to a stop in the road and when push button to restart the lights went out and no movement of engine. Even though the lights came back on when button was pushed again nothing seemed to respond. Emergency flashers and radio did work. Transmission selector would not go to neutral to allow movement from the road. I called wrecker service and set in the truck for about a hour waiting and nervous about someone hitting me from behind as it was a dangerous spot just around a corner. The wrecker could not get the truck in neutral after several attempts ended up dragging the truck to get it loaded. Since I was within a mile from my home and it was midnight on Saturday I had him take it to my home. Monday I called Thompson GMC and wrecker came took it in to the dealership in Springfield MO. Tuesday 8:30 am I received a text from service saying that it was going to have to have a new motor as it was completely full of metal shavings. The replacement 6.2 engines were on backorder and they didn’t know when they could expect them. I was shocked as I had not had any trouble and really liked my truck to this point. I tried to get dealership to trade for another truck but they didn’t seem to want to wait for the engine either and would not give much for trade on a 18 month old truck. Obviously, this is a frustrating position as the truck is a huge part of my life. In the last few days I have found that GM has known of the problem for some time and they don’t have a remedy for me to recover my investment in their faulty product. I saw on internet where NHTSA had more than a 1000 complaints so I decided to add mine. You can bet that their are many many more that have been repaired before the motors went on backorder that are not reported. GM needs to step up NOW!
