My 2023 GMC Acadia experienced a complete electrical system failure while driving on an interstate highway. During the incident, the vehicle lost all electrical power, including hazard lights and steering assistance, and could not be shifted into neutral. The vehicle became immobile in active traffic and required police-ordered towing due to safety risk. This incident was the second alternator failure within six months. The second failure involved a GM-installed replacement alternator that failed prematurely. Both incidents required towing, and the second created a significant roadway safety hazard.

While driving under normal conditions, the vehicle experienced a sudden, violent deceleration. The emergency braking and collision avoidance systems activated spontaneously, as if the vehicle had struck or was about to strike an object. There was no obstacle, impact, or external threat present. This uncommanded braking caused significant physical stress and injury to the occupants. Critically, multiple safety systems failed during the event: The seat belts did not lock, failing to restrain the occupants; The airbags did not deploy, despite the severity of the deceleration; no warning indicators or diagnostic alerts were present before or after the incident. These failures directly contributed to physical injuries, including TBI (concussion, spinal trauma, etc.) which required emergency medical treatment and ongoing care.
