2025 GMC Canyon problems

“On Sunday, November 16, 2025, my vehicle, which had only 2,004 miles on the odometer, experienced a catastrophic failure of its braking system. The warning lights illuminated, and I received a diagnostic alert text message from OnStar stating that the driver’s side rear tire needed air. Subsequently, the dashboard displayed a brake failure warning, advising me to proceed with caution as the braking system was inoperative. I drove the vehicle home and then took it to a nearby Buick GMC dealership for repairs. I dropped the keys into the overnight box and returned to the dealership the next morning. I was informed that a technician would contact me. On Wednesday, November 18, 2025, at 3:00 PM, I received a call informing me that the braking system was indeed malfunctioning. The technician mentioned that it would take approximately 48 hours to obtain the necessary parts; however, there was a supply chain issue that could delay repairs for potentially 30 days or longer. The vehicle was purchased on April 18, 2025, and had only 2,004 miles on it at the time of the incident.”

“On [XXX], at approximately 4:10 PM, I was at the McDonald’s drive-through located at [XXX] and [XXX] in Springfield, Missouri. I was stopped at the final service window. As I pulled away from the window, I approached a 90-degree left turn heading south. I removed my foot from the accelerator pedal to allow the truck to coast slowly around the corner, as the area is heavily pedestrian and requires caution. While coasting with my foot completely off the gas pedal, the truck suddenly and rapidly began to accelerate on its own. I immediately applied the brakes, and the unintended acceleration stopped right away. At that point, I called Thompson GMC in Springfield, Missouri, at 4:17 PM to report the incident. This was the second time this has occurred. The first incident happened several months ago on [XXX] north of Strafford, Missouri. While navigating a curve, I lifted my foot off the accelerator to coast, and the truck again experienced sudden, hard acceleration. I quickly applied the brakes, and the acceleration stopped immediately. I called Thompson GMC at that time as well. They advised me that I could bring the vehicle in for inspection, but without a check…”

“*COMPONENT SYSTEM FAILURE- MASTER BRAKE CYLINDER *SAFETY PUT AT RISK - AS BRAKE SYSTEM FAILURE MEANS THE BRAKES WERE NOT WORKING AS THEY SHOULD. *PROBLEM HAS BEEN CONFIRMED BY GMC AND THE DEALERSHIP AS A KNOWN ISSUE IN NEW VEHICLES. *THERE WAS NO WARNING OR ALERTS PRIOR TO THE DAY 8/23/25. ON THAT DAY WAS THE FIRST WARNING LIGHTS I SEEN. *PART ON BACKORDER FOR THE FORSEEABLE FUTURE. GIVEN THE MILEAGE AND BEING BRAND NEW AND NOT HAVING THE PART POSSIBLY FOR MORE THAN 30 DAYS I FEEL AS IF I SHOULD BE GIVEN ANOTHER VEHICLE AS I THINK IT WOULD FALL UNDER THE LEMON LAW? 2025 GMC CANYON AT4 MILES-2,417”
