2 issues. The radio will go blank and not work regardless of the method using to listen. Example- Sirius/XM or FM/AM. The vehicle will accelerate/jerk forward/backward dramatically compared to the pressure on the pedal. Scared to let anyone else operate the vehicle to prevent accident. Scared to back up to a camper or trailer because it is unpredictable how far it will jerk. No alerts or warnings. Has been taken to the dealer shop many occasions. Accelerator pedal has been replaced. Transmission reprogrammed. The radio/electronics has been updated on multiple occasions. Still both problems exist. GM has been contacted and there is an open case; however, still not resolved. This issue began when purchased in 2023 and continues in 2026. Neither the dealer nor GM seem to have a solution.

Upper bezel of front grille blew off driving down the hwy landing in oncoming lane of traffic. This is a known problem to GMC on late produced 2022 model year and issued a safety recall #XXX to replace the bezel and reinforce mounting points. I bought my 2023 GMC XXX and it was made in [XXX] so good chance it was made in 2022 and I could of had one of the faulty grilles. If not GMC still has a problem with upper grilles detaching while driving. I have talked to my dealer and GMC customer satisfaction with no help offered. I have bought a new grille and installed it.

The contact owns a 2023 GMC Sierra 1500. The contact stated that while driving 35 MPH, the vehicle lost power steering functionality. The "Service Power Steering" message was displayed and ESP warning light was illuminated. The dealer was contacted and diagnosed the vehicle with a short circuit in the module used to control the rack-and-pinion system, which had blown the fuse. The manufacturer was contacted by phone and made aware of the failure. The failure mileage was approximately 83,000.

The contact owns a 2023 GMC Sierra 1500. The contact stated that while driving 70 MPH, the engine seized, causing the vehicle to stall and lose motive power in the middle of the interstate. The vehicle was unable to restart and was towed by OnStar service. The vehicle was towed to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was scheduled to be repaired by the dealer. The manufacturer was made aware of the failure by the dealer.

The front upper grill broke and flew off the truck at highway speeds nearly causing a wreck. Zero previous damage. Simply broke at the connecting points without cause. . Pretty unreasonable for a 75000 dollar truck to have the upper grill just dislocate itself and nearly cause a major wreck at highway speeds

On September 11, 2026, while driving my 2023 GMC Sierra 1500 Denali Ultimate at approximately 70 mph on the Buckman Bridge (US 295 S), the painted upper grille/hood molding located between the hood and the top of the grille suddenly detached from the vehicle. Before I purchased the vehicle, it had sustained damage to the front fascia during transportation/shipping. As part of the repair prior to my purchase, the upper trim piece in this area was replaced by General Motors. To my knowledge, the replacement was performed by GM as part of the pre-delivery repair. The vehicle had not been involved in a collision or impact prior to the failure while I owned it. The component detached while the vehicle was traveling at approximately 70 mph on a bridge and entered active traffic. I was unable to determine what happened to the component after it entered traffic or whether it struck another vehicle. At the time of the incident, I did not initially realize exactly which component had detached. I subsequently determined that the missing part was the painted upper grille/hood molding/front upper grille deflector. I am reporting this because I have since learned that GM issued safety recall N242490120 / NHTSA recall 25V060 for certain 2022 GMC Sierra 1500 vehicles involving the front upper grille deflector. That recall describes fracture of the attachment points and the possibility of the deflector completely detaching while the vehicle is being driven. My vehicle is a 2023 model, but the component and reported failure appear substantially similar. The failure occurred at approximately 70 mph and caused a large exterior body component to enter active traffic, creating a potential hazard to other motorists. I am requesting that NHTSA document this incident and investigate whether the defect addressed by recall 25V060 also affects 2023 GMC Sierra 1500 vehicles, including vehicles in which the upper trim piece had previously been replaced by GM.

Addendum to previous submission # 11760415. At 15,033 mileage again multiple codes present along with a rough running engine. Dealership service dept confirmed on 9/17/2026 verification of 10 active codes , 2 pending codes triggering check engine light. Onstar notification as well of engine issue. Prominently codes P0016 & P0340 lead the list. PICO testing was stated to have failed two out of 3 parameters. Officially stated now as an engine defect which is being directed to be replaced with a remanufactured , not new , motor. Very fortunate to not have experienced dramatic failure ( loss of propulsion ) at highway speeds far from home. Even though this vehicle warning's persisted prior to this ultimate conclusion it was insisted that ultimate failure was necessary before any resolution would be instituted. A safety conundrum if you will. A high probability safety risk of continued use ( based on historical data on this known engine failure risk ) to ‘ prove ‘ it would fail like many others already have. A fair assessment of my personal experience.

On several occasions this Saris Superclamp bike rack has dropped from an upright position to a tilted position when there is a bump/dip in the road. A driver following has later reported to me that the rack/bikes falling quickly startled him and led to him braking. The bikes have not fallen from the rack when it drops down but I am concerned about the possibility. I have contacted the manufacturer and they will send me parts to repair if I can provide the original sales slip which I can not find. The part is available for purchase for 200 which is nearly half the cost of the rack. I have communicated to the manufacturer that this defect is a safety hazard and they should rectify the issue at no cost. They have refused.

The upper chrome grille molding fractured at the clips and completely detached at highway speeds, creating a dangerous flying projectile. This is an identical material failure to NHTSA Campaign 25V-060. The defective part or assembly process clearly extends into the 2023 model year.

I was driving down the George W. Bush Highway in Dallas, Texas, and the front top bezel above my grill flew off and went over the top of my truck. I have no idea if it landed safely or damaged other vehicles behind me because I was in very thick traffic. This is extremely dangerous as I could injured people driving behind me potentially impaling someone as I was going 70 mph per the speed limit. Just both are being recalls on the 2022 GMC model of my truck. The dealership refused to fix this for me and quoted me over 500 to get this repaired.

Truck rear wheels locked up while going between 45 - 50 mph nearly causing accident. Driver behind me had to lock-up their breaks to avoid collision. This is happening every time I drive the truck for more than 30 minutes. It is happening multiple times a day now. I cannot drive truck - too unsafe to drive. Tried getting serviced, but local GMC dealer said they are backed up with truck transmission issues and can't get mine in until Sep 15 - 3 weeks after first reporting. No warning signs. The locking of rear wheels takes me by surprise.

Purchased above listed vehicle new in XXX. Immediately noticed a 'coolant' smell in cab. brought vehicle in for coolant smell issue on XXX and XXX. We were told that there was no issue until finally on XXX we were told the radiator needed to be replaced at OUR expense. XXX we received a letter from GMC advising the "engine coolant control valve" may fail. In XXX while driving on mountain roads (we live in [XXX]) the check engine light came on and while at 50 mph, the vehicle went into "limp mode" we lost power and speed was immediately reduced. We now know that a symptom of that valve failure is coolant smell in the cab of the car, a problem we had attempted to address with GMC from the beginning. We could have had a serious accident driving on a busy mountain road when this failure occurred. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

A GM warranty engine replacement was performed at Heyward Allen GMC in [XXX] on XXX at 70,415 miles. We purchase the vehicle on XXX with 73,904 miles and after driving for a month started having multiple malfunction indicator lights displaying, and experienced a no start condition. We took the vehicle to the Don Ledford GMC dealer in [XXX], and they performed a high level inspection. They found missing mounting brackets, loose wiring harness wires, broken and missing bolts. Issues all related to an engine replacement procedure. Deeming the vehicle unsafe to operate. The origin dealer that was paid through GMC to replace the engine is now refusing any responsibility for resolving these issues. Technicians have video evidence of the workmanship issues, documenting the sub- par repair work performed during the engine change. The vehicle now sits at the Don Ledford GMC dealer awaiting an estimated $4400 repair, before the vehicle is safe to operate on the road. The vehicle has been at the Don ledford dealer since XXX, and is still there today, XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The 6.2 engine in my truck failed while driving and it has been determine that I need a new motor. This motor was on the recall list. I brought it in for the PICO recall test in October we 2025 and it passed. They then changed the oil for a much more expensive 0w40. The engine failed in August leaving me stranded on side of the highway. It has been at the dealership since August 7th. There is no eta on when the new motor and parts will be available because I’m being told that some parts are on back order. I have looked into trading it in and the value of this truck due to the 6.2 engine recall is significantly lower that it should be. It’s half of what I paid for it 3 years ago. I incurred towing fees and Uber fees. I am no without a truck to tow with.
