2023 GMC Sierra 1500 Body & structure Problems

The bezel that attaches to the top of the grill flew off while I drove down the interstate. It went over my truck and almost hit the car behind me and in the lane next to me. The mounting points failed and most of them as still connected to the grill. The grill has some broken plastic mounting and several cracks in the grill around the connection points. I took the truck to the GMC dealership and they looked at it then told me to contact GMC. I have dashcam video (front and rear) of the part detaching and traveling back into traffic behind me.

While driving at highway speeds the upper front grill part of my gmc sierra truck simply flew off. It went airborne and flew behind me causing traffic directly behind me to swerve out of the way into other traffic lanes to avoid missing the grill piece from hitting them. There was no indication of the part being loose or rattling or any warning. It simply just flew off. This could have easily caused an accident or flew into my windshield and cracked it as well. This needs to be investigated. This is a common gmc sierra 2022+ body style issue as I have heard from other owners experienced the same thing.

Upper grille deflector flew off going down the highway and hit the windshield and cracked it. Truck is a 2023 and warranty or dealership will not cover the repairs. Its a $85k truck and I don't think pieces of it should just fly off going down the highway. What if it hit somebody walking or riding a motorcycle.

Front grill deflector flew off on the highway causing visibility issues and damaging paint on the truck. The clips broke and the piece shattered when it hit the roadway. Theres a recall on the 2022 and my 2023 is the exact same design with the exact same part. Gmc doesn't want to recall more trucks and has neglected this problem.

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.

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.

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 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.

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.

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)

while driving my 2023 GMC Sierra AT4 at highway speed, the front grille piece (GM part 84957848, roughly 3 feet or longer) detached from the vehicle without warning and flew off into the roadway. The piece landed on the shoulder rather than in a travel lane, but given its size, it could easily have struck another vehicle or caused a serious accident if it had landed differently. I was then forced to stop on the highway shoulder to retrieve the part, which put me in an unsafe roadside situation with traffic passing at highway speed. This part had all its retaining clips still intact, indicating a failure of the part/mounting itself rather than a missing clip or improper installation. part number 86274905
