  • 2022 GMC YUKON
    - PLYMOUTH, MN

    6.2 Liter Engine failed at 34,000 miles. The engine failure was confirmed by Luther Brookdale GMC in Brooklyn Center Minnesota. They said the engine failed and replaced it with a new 6.2L engine as part of the recall. No warning lights, or indication of failure, some very minor noises were coming from the engine. It did not fail on the highway, but at the dealer but could have killed my family if it happened on the highway.

  • 2021 GMC YUKON
    - Rupert, ID

    The contact's daughter owns a 2021 GMC Yukon. While the owner was driving at an undisclosed speed, there was an abnormal ticking sound coming from the engine compartment. The sound was intermittent but frequent. The vehicle stalled intermittently with several unknown warning lights illuminated. The vehicle was taken to an independent mechanic, who advised that the vehicle needed to be taken to a dealer for additional assistance. The vehicle was taken to a dealer, but it was not yet diagnosed. The contact researched online and related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not included. The manufacturer was informed of the failure and confirmed that the VIN was not associated with the recall. The failure mileage was approximately 154,000.

  • 2024 GMC SIERRA 1500
    - League City, TX

    At speeds of 65-75, both with the adaptive cruise control enabled and disabled, I accelerated a little bit to pick up speed and pass another vehicle. The vehicle responded initially by gaining speed, then it feels like I hit something and the front brakes lock up for 1-2 seconds and the tires start screeching from sliding, then everything resumes to normal. I was very shocked during a recent roadtrip when this happened 4-5 times. I feel like my safety and my family’s safety is at risk and of the 2 dealerships I called, they don’t prioritize it and make it seem like a minor repair.

  • 2015 GMC ACADIA
    - Beachwood, OH

    The contact owns a 2015 GMC Acadia. The contact stated that the automatic alert system anti-theft system locked up. The contact stated that the vehicle failed to start. Additionally, the safety sensors in the mirror and the rear of the vehicle became inoperable. No warning lights were illuminated. The vehicle was towed to the local dealer, where it was diagnosed and it was determined that the driver’s and passenger’s side mirrors, and reverse light sensors needed to be replaced. The vehicle was repaired on three occasions, but the failure persisted. The manufacturer was contacted and confirmed that there was no recall for the failure. No assistance was provided. The failure mileage was approximately 20,000.

  • 2023 GMC SIERRA 1500
    - Lansing, MI

    Our truck had just passed 60,000 miles when the engine seized. The recall procedure was completed in January, and the engine passed the test at that time. We were also using the recommended 0W-40 oil. Despite following all guidelines, the engine still failed. This shows that the procedure GM has outlined is not sufficient to determine whether an engine is actually in good condition.

  • 2025 GMC YUKON
    - BALA CYNWYD, PA

    My 2025 GMC Yukon's infotainment system has repeatedly failed. The huge center screen frequently goes black upon starting the car. Once the screen goes black you are unable to control literally dozens of the vehicle's features including but not limited to climate controls, safety features, heated/ventilated seats, gps, lane assist, the radio, no backup camera, etc. When the screen blacks out, the vehicle automatically turns the heat on to 76 degrees every single time and blows hot air from the front windshield defogger vents only. The list of features controlled by the touch screen is quite enormous. I have taken the vehicle to the GMC dealer four (4) times for software updates, none of which solved the problem and they have admitted they have no fix for this issue. The issue is widespread, as I have encountered literally hundreds of owners online like myself dealing with the very same problem; brand new cars that just do not work. GMC has done absolutely nothing to get to the bottom of this.
