Narrative

My 2020 Chevrolet Blazer experienced severe mechanical problems, including stuttering, loss of power, and the engine shutting off unexpectedly while I was driving. The vehicle subsequently would not operate normally. On February 25, 2026, Rick Hendrick Chevrolet Duluth performed a diagnostic inspection and recommended nearly $20,000 in repairs, including transmission-related repairs. However, the dealership did not identify or disclose any alternator fire damage or related electrical safety concerns. In October 2026, an independent mechanic discovered significant burn damage on the alternator. The damage was visible externally, and further inspection of the alternator’s interior revealed additional evidence of burning. I believe this condition may have contributed to the vehicle’s sudden loss of power and shutdown. This presents a serious safety concern because an unexpected engine shutdown while driving can increase the risk of a collision, and an electrical failure involving burning components may present a fire hazard. The vehicle has not been driven since the dealership’s inspection. The damaged alternator has been preserved, and photographs were taken documenting its condition. The component is available for further inspection upon request. I am requesting an investigation into this alternator failure and the associated vehicle safety risks.
