2024 GMC Sierra 1500 Body & 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.

Incident

Oct 24, 2026

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.

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.

I was driving home from family’s house 2 hrs away and got home late. When I got home I noticed the upper front grille assembly or top chrome trim piece for the 2024 GMC Sierra 1500 Denali Ultimate flew off at some point while driving. That could have caused an accident for others and myself but luckily no one is harmed.

top grill deflector flew off at highway speeds creating a safety hazard for me and others in the highway. 2022 GMC Sierra with the same part and grill was previously recalled for this identical issue. 2022-2026 models have the same problem and should be included in the recall.

Incident

May 25, 2026

The front upper grille deflector detached and hit my windshield and bounced off behind me during a drive at normal highway speeds. This created a random flying debris object that appears to have been a problem with the 2022 and later Sierra 1500 models; however, the recall only appears to address the 2022 model. It also appears quite common for the 2024 year model as well. Vehicle has never been in an accident so nothing beyond typical use would have caused damaged to the connections. The plastic connectors appeared to have failed.

The front upper grille broke off and detached at highway speeds. The grille impacted the hood, causing a scratch and dent and became a road hazard and has the potential to cause an accident. This is the same failure reported in NHTSA Campaign Number: 25V-060 that only covers 2022 model years. Research online indicates failures in 2022, 2023 and 2024 vehicles. GMC to date will not warranty or recall this gross safety violation.

While driving 65mph in my 2024 GMC Sierra Denali Ultimate on Interstate 270 in Hilliard, Ohio my chrome grill deflector just flew off and hit my windshield. It then went over my truck and almost caused a major accident with the cars and semi-trucks behind me. I was lucky to maintain control of my own vehicle! It appears to me that the mounting fractured and it looks like manufacturing defect. Looks like the same issues recalled in 2022 year models. How many have to die before GM fixes this issue? They now want $1,500 for a new grill on my 2024 truck.

I was driving on the highway (using cruise control) when the front bumper grill started vibrating (so I tried to slow down) but it kept flapping and flew off before I was able to pull over. I then pulled over on the shoulder and had to walk back to retrieve it. My safety was put at risk because it could have hit my windshield and caused me to have an accident, or, it could have hit someone or another vehicle. I have it and it is available for inspection. It has not been inspected by anyone yet. There were no warning signals prior to the failure.

2024 GMC Sierra 1500. While driving approximately 75 MPH, the front chrome grille deflector came loose from the passenger side of the vehicle and started flapping. Before I could safely pull over it became detached and flew over the hood of the vehicle striking the front windshield before nearly hitting another moving vehicle behind me. This caused damage to the hood, the other driver did not stop. While the 2024 model vehicle is not listed in NHTSA Campaign Number: 25V060000 (STRUCTURE) recalled on the 2022 model, GM lists the same part number for the 2022-2024 models, therefore the recall should include these years as well. The failure mileage was 27,500.
