GMC Complaints

[XXX] has a trailer brake control module issue that causes the trailer brake to periodically disengage and reengage. Unfortunately, I had to drive across the country on a military PCS move with this intermittent failure. GMC has provided numerous surveys to ask about my experience with my new GMC. Overall, the vehicle adequate, and in each survey I have annotated this issue. However, it does not appear the issue is being taken seriously as I have not seen a recall. A trailer brake that intermittently fails is extremely dangerous. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2012 GMC Acadia. The contact stated while driving 60 MPH, the liftgate lamp detached from the vehicle. No warning lights were illuminated. After a visual inspection, the contact observed that the adhesive had severely deteriorated. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who was unable to diagnose the failure. The vehicle was repaired, but the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was 175,000. The VIN was unavailable.

The contact owns a 2017 GMC Acadia. The contact received notification of NHTSA Campaign Number: 23V334000 (Air Bags) however, the part to do the recall repair was not yet available.

The component or system failed was the transmission 4 different times. A new transmission was put in the car just 6 months after purchasing from a dealer. The transmission lasted close to 3 years being shy only a few days before the transmission warranty expired. So a new transmission was provided by the transmission owner at no additional cost for the transmission but we had to pay $1600 out of pocket for labor. That transmission lasted for 2 months before failing again which caused us to have the truck towed to our home to decide what our next step would be. So we had it towed to Tire max and they put in another transmission by the same manufacturer which we only had 2 days left under the warranty. That transmission failed within 2-3 days so we took it back to a different Tire Max location and they put in another transmission which did not cost anything for us by the manufacturer including labor. This transmission has now been in good standing since 12/20/23.

The driver's side floor mat will not stay in place because the device that is supposed to hold it in place is broken. The floor mat is now able to move forward and interfere with the function of the brake and/or accelerator. Both the dealership (Castle Rock GMC, Colorado) and GMC Customer Care (Case #: 91-11325687695) have ignored all requests to address this and other issues. I have also written letters to GMC Corporate and the Castle Rock GMC General Manager, both of which were also ignored.
