2022 GMC SIERRA 1500 Complaints

Upper grille flew off on interstate. Hit windshield and landed in median. I have the black grill not covered in the recall.

P2101 Reduced Engine Power Idle instabilitystruggling to idle correctly, hunting/surging slightly, and possibly going into reduced-power protection mode. While driving engine reducing power, struggles then surges forward. Ive taken it to GMC however the techs say they have to experience the situation themselves and are unable to diagnose

My 2022 GMC Sierra 1500 was subject to GM safety recall N242490120 / NHTSA 25V060 for an upper grille deflector that could detach from the vehicle. The recall repair was completed by my GM dealership in June 2025. In late August 2026, while driving normally on the highway, the same upper grille deflector detached again in the exact manner described by the recall. There was no collision, impact, or other outside damage that caused the failure. I was able to retain the detached deflector due to my attentiveness however, it was close to detaching and either busting mine or someone else’s windshield. Upon inspection, the adhesive and retainers from the previous recall repair are still clearly visible, and the bonding appears to have separated. I have photographs documenting the failed attachment points and still possess the undamaged detached component for inspection. My GM dealership inspected the vehicle after this failure and determined that the front grille assembly should be replaced. However, because the recall is shown as previously completed, GM has stated that the recall cannot be reopened. GM Customer Assistance offered only $251 toward a $1,673.82 repair, leaving me responsible for $1,422.82 to correct the same safety defect that the recall was intended to remedy. I am filing this complaint because the recall remedy appears to have failed, allowing the recalled component to detach from the vehicle again. A grille component detaching at highway speed could strike another vehicle or create a roadway hazard. I am concerned that other vehicles repaired under this recall may experience the same post-recall failure. I request that NHTSA review the effectiveness and durability of the remedy used for recall N242490120 / 25V060.

The piece in front of the hood detached and flew off while riding down the highway.

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving approximately 65 MPH, the transmission shifted to neutral(N), and the contact was unable to control the vehicle. The vehicle was coasted to the side of the road, and the transmission failed shift into park(P), reverse(R), or drive(D). The message "Conditions no Longer Exist for Driving," was displayed on the screen. The vehicle was towed to the dealer and was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The contact was informed that the nuts were welded to the engine, causing a failure with the engine overheating. The failure also occurred while driving 65 MPH, and the transmission shifted into neutral with the same message displayed on the screen. The vehicle was towed back to the dealer, and it was diagnosed with engine failure. The contact stated that the engine was replaced. The dealer informed the manufacturer of the failure. The failure mileage was approximately 34,000.

On August 22, 2026, while driving my 2022 GMC Sierra westbound on State Route 84 at highway speed, with strong westerly winds of approximately 35 knots, the front passenger-side wheel-opening molding/fender flare completely detached from the vehicle without warning. The detached molding struck the passenger-side exterior mirror and narrowly missed a motorcyclist traveling behind me. This created a serious safety risk because a substantial exterior component became a projectile at highway speed and could have struck the motorcyclist or another vehicle. There were no warning lights, messages, unusual noises, or other symptoms before the failure, and there was no known collision or impact preceding the incident. I did not initially know what had detached. After arriving home and inspecting the vehicle, I discovered the entire passenger-side front wheel-opening molding was missing. The detached component was not recovered. I reported the incident to my GMC dealer, which performs my regular service and warranty work. The vehicle was inspected on August 31, 2026. The dealer declined warranty coverage but, to my knowledge, did not determine why the component detached. Afterward, I inspected the corresponding driver's-side molding and found a substantial visible gap at its leading edge between the molding and vehicle body. Comparison with other GMC Sierra vehicles of the same model showed their moldings appeared to sit substantially more flush. The vehicle and remaining molding are available for inspection, and I have photographs documenting the condition. The cause of the failure is currently UNKNOWN. I have escalated the incident to GMC Customer Assistance under Case #109189284 and requested a product-safety review. I am concerned there may be an installation, attachment, or component-retention issue that could allow these moldings to detach while driving.

The contact owns a 2022 GMC Sierra 1500. The contact had experienced several catastrophic failures with the engine and transmission. The contact stated that while driving 40 MPH, the vehicle shut off without warning, and lost power. The vehicle was towed to a dealer for an engine replacement. On another occasion while driving 65 MPH, the vehicle shut off without warning and the wheels locked up. The vehicle was towed to GMC of Rochester (4646 E Frontage Rd, Rochester, MN 55901), where a second engine failure was diagnosed and the vehicle was repaired under an extended warranty. Upon retrieving the vehicle, the vehicle was hesitating while depressing the accelerator pedal, with the messages "Reduced Engine Power" and "Check Engine" displayed. While attempting to reverse(R) into a driveway, the vehicle became immobile. The vehicle was towed to Red Wing Chevrolet (2500 US-61, Red Wing, MN 55066), and the technician diagnosed the vehicle with total transmission failure. The contact was informed that there was heavy metal debris inside the transmission pan. The manufacturer was notified of the failure but declined to assist. The vehicle remained with the dealer. The failure mileage was 12,000.

My 2022 GMC Sierra started hesitating two weeks ago between the speeds of 17-35 mph. It also hesitates going downhill. When I try to accelerate it hesitates causing a serious safety issue for me driving. I cant trust to move when I need to move across a busy intersection with semi tractor trailers coming at me. I can trust it to tow or haul anything anymore. This is well known and documented problem General Motors has and the company deems it "Normal Operations" which is totally not normal.
