    Driving vehicle at approximately 70 mph when a semi truck passed me going the opposite direction. The upper grille deflector / molding section of my front end grille blew off and landed into on coming traffic. I understand a recall was issued for the same problem on the 2022 models, but not the 2023 model.

    600 miles and 3 months out of warranty the dash completely disappeared. Dealership says the costs is in excess of $1600 to fix the issue. I have researched this and it is a common problem with these trucks and it needs an instrument cluster. Given the fact that GMC controls the panels to these trucks I feel certain that this is actually caused by them and should be fixed under a recall. We have owned the truck 6 months. We are not able to see the speed limit, gas limits or anything on the dash any longer.

    While driving my 2023 GMC Sierra 1500 AT4 at highway/interstate speed, the front upper grille molding/deflector unexpectedly detached from the vehicle. There was no collision or known impact immediately preceding the failure. I recovered the detached molding and inspected the vehicle afterward. Multiple molded attachment points on the back of the upper grille molding are fractured/broken. Several of the attachment retainers and mounting hardware remain attached to the vehicle. Photographs were taken of the detached molding, broken attachment points, mounting locations, and the vehicle after the incident. I have retained the failed part. I am aware of NHTSA Recall 25V060 / GM Safety Recall N242490120 concerning certain 2022 GMC Sierra 1500 vehicles in which front upper grille deflector attachment points may fracture over time, potentially allowing the deflector to detach from the vehicle and become a road hazard. My vehicle is a 2023 model and is not currently included in that recall, but the failure I experienced appears similar to the failure described in that campaign. I am reporting this incident because the component detached while the vehicle was traveling at highway speed and could have struck another vehicle or created a roadway hazard. I request that NHTSA document and evaluate this failure and determine whether similar failures are occurring in 2023 GMC Sierra 1500 vehicles. The vehicle has not yet been inspected by a dealer or manufacturer. There were no warning lights, messages, looseness, or other symptoms noticed before the molding detached. The failure occurred suddenly while the vehicle was in motion and created a potential road hazard for following motorists. The failed molding remains in my possession and is available for inspection. My vehicle is a 2023 model and is not currently included in Recall 25V060 / GM N242490120, but the observed attachment-point fractures appear similar to the failure described in that recall.

    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 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

  14. Filed Sep 19, 2026Failure Sep 11, 2026Fleming Island, FLBody

    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.
