I purchased my GMC Sierra AT4 from your Oman GMC distributor called Moosa Abdulrehman Hassan. The vehicle suddenly stops and transmission automatically shift from 'D' driving mode to 'N' natural. First it happened when the vehicle driven 200km only when I took it to dealer Moosa Abdulrehman Hassan, they re-programmed the vehicle and doesn't know what the problem is. Second time happened when the vehicle was driven approx. 1,600 km and 3rd time again happened on [XXX], engine stopped and transmission shifted automatically from D to N, I have to start the engine and continue my journey. Again, I brought the vehicle to GMC dealer Moosa Abdulrehman Hassan. They kept the vehicle for almost one week and unable to demonstrate or diagnose the problem and asked me to collect the vehicle. Its high risk to drive the vehicle, when suddenly the engine stops and the gear shift from 'D' to 'N' while driving. I had option to choose, Ford 150 or Dodge Ram I bought GMC because it suppose to be reliable and have the best safety features. But I really regret now why I have purchased it, there are no technicians in Oman with GMC dealer to identify and fix the problem. I can't drive the vehicle in such condition, risking my life and life of other drivers on the road. The vehicle is parked in my Garage, it new vehicle just completed 1800 km. The the dealer the solution is very simple, either fix the issue, or replace the car or refund my money back, the dealer is not doing any of these. Before taking legal action and reporting it to the court, which will bring shame to GMC reputed brand. I though I'll give my final try to report it to you. You are the manufacturer may be have a solution. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

GM is recommending that I replace my brakes for the 3rd time within 30,000 miles but cannot explain the irregular wear. I am confident that there is a larger issue causing this is the brakes failing are just a symptom of a larger issue that have failed to address after 6 dealership visits, escalating (twice - due to first advisor never getting back to me) to GM customer care, emailing an executive, regional service manager, and countless hours to fix the safety issue of my brakes (and the larger root cause issue). GM Customer Care Case #[XXX] - BRAKE SAFETY ISSUE 2024 GMC Sierra AT4 (VIN: [XXX]) - 46,000 miles Nov 2023: 1st visit - Brake squeal at 25K. Pads replaced, GM denied warranty. Early 2024: SAFETY ISSUE RETURNED at 30K miles. May 2025: 2nd visit - Worsening brake noise. Dealer couldn't replicate despite video evidence. Recommended $500 repair. Manager acknowledged "irregular/abnormal" wear. June 2025: 3rd & 4th visits - Tech found unexplained "weird line" on pad. Manager Kyle confirmed unusual wear but no root cause identified. June 10: Opened GM case #[XXX] after dealership failures. July 7: GM failed to coordinate promised appointment. July 14: 5th visit - Les Stanford Buick GMC, Ferndale. Tech rode with me, CONFIRMED BRAKE SAFETY ISSUE but offered no solution. CRITICAL SAFETY CONCERN: Recurring brake defect with abnormal wear patterns acknowledged by multiple technicians. Same brake failure pattern occurring 3 times in 18 months poses serious safety risk. Despite 5 dealership visits, video evidence, and confirmed defect, GM refuses warranty coverage while acknowledging the problem exists. Issue remains unresolved - I've exhausted all customer remedies. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

I recently purchased a 2024 GMC Sierra 1500. On July 14, 2025, I was informed of a recall involving the L87 engine and a risk of loss of propulsion. This is a major safety concern that can cause the vehicle to suddenly lose power while driving. I was advised not to drive the truck due to safety reasons, but GM has not released a fix or repair solution for this recall. This issue puts my safety and the safety of others at serious risk, as the vehicle could lose power without warning on the road. I contacted the dealership (Findlay Chevrolet, Las Vegas) and GM directly, but no timeline or resolution has been provided. I am now stuck with a vehicle I cannot legally or safely drive and no support from the manufacturer to resolve the issue. There were no warning lamps or prior symptoms before the recall was issued. The problem has been acknowledged by the manufacturer but remains unresolved. The vehicle has been inspected and the recall confirmed by the dealership, but they stated there is no fix currently available. I am requesting that NHTSA take this seriously and put pressure on GM to either provide a safe solution, a loaner vehicle, or a buyback program until the recall can be resolved.
