2022 GMC SIERRA 1500 Complaints

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.

The engine seized up at approximately 20,000 miles while exiting the highway. I took the vehicle to GM and they needed to replace the entire engine. I was told it was a common problem with the 6.2 engine by the service manager.

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.

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.

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!

6.2L Engine burning excessive oil, so dealer per GM started an Oil Consumption test at 34,457 miles went through the process until 45,145 miles and dealer took it in at 45,468 to tear down engine, I contacted GM Aftersales and Customer Service VP and he had a representative start working the case, Engine was found to have scored cylinders on the driver's bank decision was made to replace engine. Engine was replaced and picked up vehicle and was told to bring it back in 5k miles for an oil change. I brought it back in 1k miles and retained the filter and used a filter cutter and inspected the filter. Filter had a significant amount of Metal and Metillac pieces imbedded in the filter (I have the filter still) I reported this to the Dealer and GM Aftersales and Customer Service, They noted this a normal! I then had the filter only changed at 500 more miles and still contained some debris, this is the second truck that I have owned the first was a 21 same issue first replacement failed in 25 miles, 2nd motor failed at start up and then I traded into this 22' and took a major financial hit on trade in, then a 3rd motor in the 21' and it made it so the truck could be wholesaled or sold, by this time I had bought this truck that has just had the motor replaced and currently have 7k on the new motor which was replaced under warranty. I feel confident that the metal debris that was in this engine is a contributing factor if not the factor that is causing the engine failures and suspect this engine will have the same demise. I welcome you to take possession of the filter and inspect it yourself. I have a video of the filter that I would be glad to share. These engine failures have cost me $25,000 in trade in loss.

Rod and bearing failure at 80k miles. I was driving down the road and the vehicle turned off leaving me stranded on the road.there was no warning

6.2L motor shut off with no warning with message on dash to shift to neutral and press start, nothing happened. Was able to restart and drive to dealership. Truck was diagnosed with blown motor (lower bearing failure) and new motor ordered.

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.

My engine locked up on me 3 times without notice or warning at all while driving 75-80mph down the highway. All the times myself and my family were put in danger of being hit by traffic and the locations were the vehicle stopped was around a curve where other drivers wouldn’t notice until it was too late. Freezing cold and could stay in the vehicle scared we might get hit while inside. Second time it stopped at around 10:30om in the middle of nowhere in [XXX]. Even the cops couldn’t get us tow. Finally 6 hours later a friend had to come get us. I reached out to the GM CEO per email and no reply. I tried to get them to take the vehicle back and after supposedly fixing the engine after having it for 3 months I got it back with no loaner to use during this time. The engine failed again a month later. Again after supposedly fixing the engine it failed a third time. If failed the first time in January 2024 and the second time in May 2024 and then the third time in July 2024. I have anxiety and now taking medication from even driving this vehicle afraid it will stop again. Replacing the engine isn’t acceptable to me. Please help. The first place to to rebuild the engine Crossville, TN (Dave Kirk Chevrolet GMC), then it to Parks Buick GMC-Greenville: 2640 Laurens Rd, Greenville, SC 29607. and then to Loves Buick GMC, 736 Saturn Pkwy, Columbia, SC 29212. I have all the email sent to GM leaders and their executive leadership team. My vehicle had only 22,000 miles on it and I guess doesn’t fall under the lemon law in SC so they didn’t want to take it back. I feel helpless in this situation. Even getting a lawyer isn’t guaranteed a win and then I’ll be out of more money. Being a [XXX] this really sucks to be treated like my life and family life doesn’t matter. I bought the vehicle brand new from Jim Buick, GMC, Cadillac in Columbia, SC. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
