GMC CANYON 2025 ENGINE

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 driverâ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.

GMC CANYON 2025 FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.
