2022 GMC SIERRA 1500 Complaints

Day1: vehicle stalled resulting in warning lights related to the batter. Day2: battery was replaced. Day 3: vehicle was driven less than 30 miles and starting making noise under the hood. vehicle stalled in road and was towed to repair shop/dealership. I then received notice the stater needed to be replace to start the vehicle to diagnose. The vehicle started and it was determined the engine was blown and needed to be replaced.

Started using oil and dealer said GMC says it can use 2 qts in between oil changes and few months later driving on interstate and quit running got it home and clinging and wouldn’t start got it to dealer said the engine seized up bearing spun. Took 2 months to get truck back and now afraid it will happen again. GMC should offer a buy back or different year of truck at no cost.

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.

Engine seized up. This is the second 6.2L engine that this happened to. The first one was a lifter failure and 2000 miles After replacement engine locked up. Brand new engine at 26000 miles. Now at 68000 the new engine seized up with no warning

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.

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.

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.

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!

On 9/23 truck just shut off while driving to work no warning just shut off costed to side of interstate got towed in at 2:30 am and was later called had engine failure. Got back out of shop on 10/16 with 86581 miles on it On 10/28 driving on interstate to ball game truck shut off again no warning costed to side got towed in again. Get call later engine failure AGAIN with 86568 miles on it. So I had the truck back less than a month with 78 miles on it with the 2nd engine failure . During all this had to purchase a new car to drive to work which is a hour each way. Now truck is fixed and we’re scared to even drive it out of town now. It really sucks they can get away with this!!!

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.
