ENGINE
While traveling on the highway the engine shut off. No warning, noises or lights where on before. Check engine light came on when the engine shut off. Was able to get off the road on to the shoulder. This was an huge safety concern as I had no way to move the truck. After getting the vehicle to the dealer it was a spun rod bearing. Had 7000 miles on it at the time. Dealer replaced the the parts and had the truck back after three weeks. Metal is oil pan. 1, 2 and 8 rod bearing spun scoring on main bearing and crankshaft. There was no issues with the truck prior. I bought it new.

ENGINE
I was on a hunting trip when my almost brand-new GMC Sierra 6.2L broke down, approximately 20,000 miles on it. The vehicle started making a ticking noise while I was driving out of state, en route to our lodge. Early the next morning the engine light came out and the vehicle came to rest close to a stop sign. I was very fortunate someone was following me in a different vehicle. The vehicle would not start afterward and had to be towed to the closest dealership. Being a new GMC owner and nearly 7 hours away from home and in an unknown area was extremely stressful. The dealership service department was closed on Saturday (the date of the incident) and Sunday. The dealership was less than helpful and did not return my phone calls on an already stressful day. My trip ended on Sunday and I was forced to rent a car at Enterprise. Unfortunately, the Enterprise I contacted did not have a truck and GMC told me that the dealership could not provide a loaner truck. I’ve needed a truck several times this month, which has caused difficulties for me and others. The vehicle has since been inspected and the service department stated the vehicle needed a new engine. This occurred 21 days ago and there is no end in sight. The service department could not tell me an exact date on when the engine would be shipped to their store.

bought vehicle in may 2022. had engine suddenly ‘lock up’ while driving on the highway to work in november 2022. towed and repaired at gym dealer through december 2022 for ‘spun bearing’. had ‘fuel sensor’ replaced in 10/23 when it failed the day before our planned fall break, towing our camper… then mid-december 2023 had camshaft part replacement when it ‘locked up’ again. got it back for 9 days when it once again ‘locked up’ (not driving this time…) and had engine completely replaced. on the first two occasions i was traveling at highway speed when all of a sudden- i lost power to the engine. thankfully i was on the shoulder side not towing anything either time!

ENGINE
While driving, I was starting to move following being stopped at a stop light and the truck experienced a complete engine seizure. I had it towed to the dealership I purchased the vehicle at and after a day or two, they indicated that GM's recommended fix to this particular issue was a complete engine replacement. The engine replacement couldn't be scheduled in a reasonable time. Grant it that the repair would have been covered under warranty and they would provide me a rental until such time it could be fixed, I decided to trade the vehicle in on an equivalent 2024 model (same truck 2 years newer) after being assured that it was an isolated incident and not part of a systemic problem. I only am writing this since I read an article the other day indicating that the NHTSA was launching a potential investigation into the same issue based on 39 complaints, at that time, regarding the GMC's 6.2L V8 small block engine. I wanted to let your organization know of my issue as well since I would assume that there are far more than 39 people/owners that had experience this problem. At a minimum, I make 40. In addition, I am now concerned about my 2024 GMC since it has the same motor in it. The article mentioned that there has not been injuries associated with the engine seizure. This is not surprising to me. It actually happened twice in my 2022; the first time in my driveway and another on the road. Note, after sitting for a couple of days in my driveway, it had started right up. I went for a ride to test it out and that is when the final instance happened. Both instances occurred when the auto off feature was engaged and only seized when trying to move from the auto "off" position back onto the "on" (engine running) position so I was not moving in either instance. Again, I am not concerned that this issue will arise in my new vehicle.

I am on my third 6.2L engine at 80k miles due to engine failure. It is absolutely ridiculous and is a safety issue for sure. It has left me stranded twice. And now GM is giving me a hard time about not wanting to cover it under warranty.

ENGINE
My 2022 6.2l V8 GMC Sierra 1500 Denali Ultimate engine failed while driving 50mph on the highway. It had 18,000 miles on the odometer. The transmission locked itself in neutral while vehicle was in motion. There were no warning lights on the dash. When the vehicle came to a complete stop, the transmission locked itself in park. When I tried to shift into drive, the dash stated, "Conditions Not Correct For Shift" and stayed in park. I was stuck in the fast lane during rush hour with no options other than to wait for a tow and hope another vehicle does not ram into me from behind. My truck was towed to a local dealership and they found metal shards in the oil and said I require an engine replacement. This happened on 12/18/2024. On 1/22/2025 the vehicle is still at the dealership waiting for a new engine.

I was pulling a trailer loaded with my UTV when I suddenly lost power going up a hill. I pulled off to the side of the road and turned off the truck. When I attempted to restart it the truck wouldn’t do anything so it needed to be towed. Upon the dealer looking at it they said the crankshaft bearing broke which is a common problem with the 6.2 motor and it needs to be replaced. The truck has just over 16,000 miles on it.

POWER TRAIN
Used my truck to back out of the driveway and wouldn't go into reverse at all. Towed to dealership and said problem was transmission valve body went bad. Dealership said TVB fail all the time in these trucks. They told me that this part is on back order and could be 2 or 3 months to get part in. GM has and known transmission issues . This truck is little over 2 years old and only has 40k on it. I'm hearing that TVB are failing while driving and creating dangerous situations and GM isn't doing anything about . Truck is under PT warranty. I asked what can't GM just put a new transmission in? They say it's not cost effective. So cost is over safety i said!

Engine suddenly started knocking and loss of power while driving on the highway. If engine had stopped or locked up it could have caused an accident. Took it straight to my dealer on Dec. 30, they said to leave it that the knocking was coming from lower part of engine. Couple weeks later they called and told me it was crank bearings. Very disappointed I only have 11000 miles on it.There was no prior warning lamps or symptoms. They have a new engine on order but said there is a nation wide back order, so no way to know how long it will take to find one.

UNKNOWN OR OTHER
The gmc trailering app will not read trailer tire pressure above 100psi. When trailer tires carry a safe psi amount above 100psi the trailering app will not be able to confirm if the trailer tire is low in pressure which could cause a massive wreck if driver did not know the trailer tire was going bad. Truck was taken to dealer, they tried to follow bulletin 22-NA-172 to have the pressure to read above 100psi. But they could not get it to work, I was told it was a trailering app issue and nothing they can do until GM takes the steps to fix the trailering app.

When traveling on the interstate at 75 MPH the trim at the top of the grill broke free, hit the windshield and blew over the vehicle. The front of the grill you can visibly see where the metal clips fail and were completely sheered off. GM Authority has a bulletin published on 11/1/2024 citing other incidents of 2022 GMC Sierra AT4 owners who have had the same situation happen to them.

STRUCTURE:BODY
Driving at highway speeds 60 mph. The upper grille (as GMC calls it) came off of the truck, hit my windshield and the car behind me also hit it. This is a known GM problem and they are not issuing a recall on this. We are lucky the car behind me didn't suffer any damage nor swerve to miss the flying piece of my vehicle. This is a huge safety concern that needs to be addressed. A quick google search will reveal many other people having this same issue. Some stating damage to their vehicle as a result.
