2024 GMC Sierra structure problems

“Subject: Complaint — 2024 GMC Sierra 1500 Denali, Upper Grille Deflector Detached at Highway Speed. To the Office of Defects Investigation, I’m filing this complaint regarding my 2024 GMC Sierra 1500 Denali. While driving on the freeway at approximately highway speed this afternoon, xxx, the upper grille trim piece located above the grille and in front of the hood spontaneously detached from the vehicle with no warning and no prior impact. It created a road hazard for other motorists. This matches the failure pattern described in Recall Query RQ26003, opened xxx, covering 2022 through 2024 Sierra 1500s. My truck is a 2024 and is not covered by Recall 25V-060, which only addressed certain 2022 models. I’m concerned the defect is not limited to the originally recalled population, and that the 2025 remedy may not have resolved the underlying attachment-point failure. I request that NHTSA include my vehicle and all similarly affected 2024 trucks in any expanded recall or investigation, and that GM be required to provide a free repair. Vehicle: 2024 GMC Sierra 1500 Denali. VIN:xxxxxxxx. Mileage: 64,952. Date of failure: xxx. Location: [XXX]. Thank you.”

“The upper front grille deflector (or chrome hood molding) on 2024 GMC Sierra 1500 AT4 with 38k miles broke off at 65 mph and hit the windshield. It could have cracked or hit a person or another car. No warning or prior issue at all. The plastic clips must have broke”

“I was driving 65 MPH on a one lane highway, right when someone went by in the other lane. My front hood moulding (hood trim piece) flew off and hit my windshield. Then drug across the cab of the truck before landing in the road. This debris was now in the road causing other people to have to swerve to miss it. I turned around and put my hazards on and grabbed it from the middle of the road. This caused other motorists to stop in the roadway for me or go into the oncoming lane of traffic to go around me. The service center from the dealership I bought it at said I would have to bring it in for estimate and didn’t confirm if others have had this same issue. This happened one day ago and it has not been inspected by anyone. There was no warnings of any kind. I didn’t notice it shaking prior or anything, it just abruptly flew off.”

“Was driving down the highway at around 68mph in a 70. When the top portion of the front grill broke off, struck the windshield and landed in the roadway. Important thing to note was that I had struck nothing or nothing struck my vehicle. I now have to pay a body shop to replace the faulty part. Incident occurred on 10/16 in Mew Braunfels, Texas, Comal County”

“The contact owns a 2024 GMC Sierra 1500. The contact stated that while driving at 65 MPH, the message "Service Safety Restraint Device" was displayed. The vehicle was taken to a dealer, where it was diagnosed that the front grille needed replacement. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that a recall would not be issued. The failure mileage was approximately 55,000.”

“I own a 2024 GMC Sierra 1500 Elevation. The front upper grille molding/trim has become loose and is separating from the vehicle. The attachment points/clips are no longer securely holding the molding in place. I am concerned that the molding could completely detach while driving, particularly at highway speeds, creating a road hazard for other motorists. The vehicle has not been involved in a collision or other event that would explain the failure. I have photographs documenting the loose molding and believe this is a potential safety defect that should be investigated.”
