2022 GMC SIERRA 1500 Complaints

Was driving down the road at 35 mph and the truck started to shake and the the transmission shifted really hard check engine light came on. Pulled over truck wouldn’t go into reverse and wouldn’t shift correctly. Had my truck towed home called the dealership they said I will need to have it towed in. Several days later the check engine light was off I took the truck around the block it was running okay. Drove it the next day it did the same thing shook really bad shifted hard and wouldn’t shift correctly my go I took reverse. Had it towed to the dealership. The dealership said it was the same problem they are having on other trucks with this same transmission truck is out of warranty and GM will not cover the cost to fix it.

The Telematics Control Module failed - it no longer functions. This affects the ability to use OnStar services, such as navigation assistance, but especially OnStar emergency services which would be needed in case of a vehicle crash or other emergency. OnStar no longer works due to the module failure. There is a backlog of at least several months, or longer, before a new module is available. Many people complain that the replacement module often fails within a few months,

On November 20, 2025, my 2022 GMC Sierra 1500 AT4 equipped with the 3.0L Duramax diesel engine began experiencing intermittent engine overheating conditions. Concerned about a potential safety issue, I contacted a GMC dealership and was advised that because no diagnostic trouble codes were present, there was nothing to diagnose or repair and that I should continue driving the vehicle. Over the following months, the overheating condition continued intermittently. On May 24, 2026, while driving on the highway, the vehicle suddenly overheated, displayed fault code P1098, and entered reduced power ("limp mode"). The vehicle lost normal performance and acceleration while traveling in traffic. This created a significant safety hazard because the vehicle was unable to maintain normal highway speeds, increasing the risk of a rear-end collision or other traffic accident. The loss of power occurred while driving and without sufficient warning, leaving the vehicle unable to safely perform as expected in highway traffic. After researching this issue, I found numerous reports from other GMC and Chevrolet owners describing similar overheating, coolant control valve, thermal management system, and P1098-related failures. Many owners report symptoms involving engine overheating, reduced engine power, and limp mode operation while driving. I am concerned that this may indicate a broader defect involving the vehicle's cooling system and thermal management components. The vehicle exhibited overheating symptoms for approximately six months before the final failure occurred. Additionally, I understand that certain GM vehicles have been subject to service actions involving coolant control valves and thermal management system components. Given the similarity of symptoms, I am concerned that the overheating condition reported in November 2025 may be related to the same type of failure mechanism, yet my vehicle has not been included in any recall or special coverage program.

On June 1, 2026 driving eastbound on I-64 in Louisville, KY. Engine shut-off warning popped up and engine immediately shut off. There were no prior warnings or unusual engine or noises. 3 passengers in car. Had to change 2 lanes and then onto shoulder while coasting and slowing down. Car was incapacitated and gave battery and 0% oil read. Oil is changed regularly and engine recall work had been performed on truck several months prior. Car at dealership, not analyzed or repaired yet.

The contact owns a 2022 GMC Sierra 1500. The contact stated upon shifting to park(P) and attempting to turn off the vehicle, the message "Shift to Park" was displayed. The contact waited and attempted to park and turn off the vehicle again, and the vehicle responded after several attempts. The vehicle was taken to the dealer, where it was diagnosed that the shifter assembly needed to be replaced due to internal short to the solenoid not allowing the vehicle to detect that it was in park(P). The vehicle was being repaired. The manufacturer was notified of the failure and a complaint filed. The contact was referred to the NHTSA Hotline to report the failure. The failure mileage was approximately 24,000.

On 05/30/26, During normal operation of my vehicle (2022 GMC Sierra Elevation) at about 50MPH the Upper Grille Molding became detached while on the Highway. The safety of other cars or motorcycles was placed at risk because the part could have impaled or impacted myself through a windshield or someone driving behind me. The problem has been known to exist in other similar models and an existing recall does exist for those models (N242490120 Chrome Grille Deflector May Detach). On 06/01/26 the vehicle was taken to a Kelly Buick GMC, INC where it was assessed. According to the representative, even though I have not been the only one to report the problem with a different model than that specified on the recall number, they refused to cover the cost of repairs because my VIN does not fall into the recall specifications. Absolutely no other symptoms were noted prior to the part failure no rattling, whistling or any visible signs.

The transmission on the vehicle failed, it is currently sitting at a GMC dealership awaiting repair. However the valve body is on back order and there is no time table for repair to occur. My family and my safety was put at risk not knowing that the 10 speed transmission could result in rear tire lockup while on the highway, also the inability to put the truck in reverse to back away from any potential hazard. The problem was confirmed by GMC of Attleboro Mass. The vehicle was inspected by technicians at said dealership. There were no prior warnings, however the truck did feel hesitant to shift on the highway a week or two prior to failure.

The contact owns a 2022 GMC Sierra 1500. The contact stated while driving, the vehicle decelerated unintendedly and failed to exceed 50 MPH on several occasions.

The vehicle was taken back to the dealer, who retrieved DTCs: P0747, indicating a pressure control solenoid A stuck on failure, and P0700, indicating a transmission control module failure. The dealer determined that the failure was related to GM Special Coverage Number: N242454441 (Momentary Rear Wheel Lock-Up); however, the VIN was not included. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance in adding the VIN to the Special Coverage. The failure mileage was approximately 95,000.

I was driving, my front grill protector that was fixed with recall flew off again. This needs to be fixed. The part flew off hit my window and almost hit two cars that were behind me. This could of resulted in a bad accident. No warnings, it just happened.

Multiple times now my vehicle has had its engine locked up while driving at highway and regular uphill driving. Along with towing aswell. I have had it repaired multiple times and last time dealer wouldn’t tell me what happened because GM wouldn’t let them figure out what happened. Along with multiple attempts at fixing the transmission and brakes that are still on going issue. Same with the engine.
