2025 GMC Canyon

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 engine light or warning light illuminated, and without the issue occurring while a technician was driving, it might be difficult to diagnose. I did not bring the vehicle in after the first incident. Yesterday, a Thompson GMC employee scheduled an appointment for me to have the truck inspected. No warning lights or check engine lights were illuminated on the dashboard during either incident. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There is a phantom chime that happens intermittently at all driving conditions when close to or below 20 degrees F. (stop and go, highway, back roads, dry weather, wet weather, clear weather, etc.). This chime does not produce any warning on the driver displays. This is dangerous because it causes the driver to look away from the road to figure out what the warning is. But no warning being shown causes one to look around for the issue. Again, taking eyes off of the road even longer. Chimes can happen a dozen times on a drive, or none at all. completely random but only happens in the temperature range listed above. This is reported on numerous forums for the current generation canyons and Colorados. This has been consistent with winter of 2025 and now winter of 2026.

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.
