FORWARD COLLISION AVOIDANCE

The contact owns a 2025 Chevrolet Blazer EV. The contact stated that while driving at various speeds, there was a clicking sound coming from the front suspension of the vehicle, and the vehicle was difficult to drive in a straight line or turn in either direction. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The contact was informed that the vehicle could not be repaired, and a buyback was offered for the vehicle. Additionally, while driving at an undisclosed speed, the Forward Collision Avoidance system erroneously activated, causing the vehicle to abruptly stop in the middle of the road. The vehicle was taken to the local dealer, who reprogrammed the Forward Collision Avoidance sensors, but the failure persisted. Additionally, the charging port had malfunctioned and became inoperable. The charging port was replaced, and the vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 200.

FUEL/PROPULSION SYSTEM

The motorized charge port door no longer opens. There is no manual operation rendering the vehicle unable to charge. This presents a potential hazardous situation if the error occurred during a road trip where there are greater distances between charging stations and services. GM customer service and OnStar could not resolve the issue when contacted.
