Consumer Description

After a major HVAC repair involving the evaporator core (performed at a Chevrolet dealership), my vehicle began experiencing serious electrical issues. The second-row 12V outlet no longer functions, and the vehicle has gone completely dead three times while the engine was off due to the auto stop/start system — once while stationary on a major highway, creating a dangerous situation. Each time, the engine failed to restart automatically, and the entire electrical system became unresponsive.
