Narrative

The vehicle has suffered repeated systemic electrical failures all while being under 8,000 miles. What component/system failed? Power distribution/fuse block, starter, fuel pump control module, horn circuit, body control module, instrument cluster, and charging system. Error codes documented include P0627 (Fuel Pump Control Circuit), U0100 (Lost Comm ECM/PCM), B1325 (Control Module Power Low), U0140 (Lost Comm BCM), and B1000 (ECM fault). All repairs are documented by the dealer, and the truck remains available for inspection. How was safety at risk? The truck lost propulsion at speed, emitted smoke from the engine bay, and became disabled in traffic, placing my family, including my toddler, in immediate danger of collision and fire. Electrical defects also disabled horn and instrument cluster, removing critical warning and signaling functions. These electrical issues have been ongoing for months and GM refuses to replace and can't seem to fix it. Has it been confirmed? Yes. Each failure was diagnosed and confirmed by an authorized GM dealer. Components replaced include fuse block, starter, fuel system computer, horn assembly, and cluster. Despite repairs, issues recur. Inspected by others? GM corporate case managers are aware and have acknowledged defects, though they have refused to issue written determinations. Insurance has not yet been involved, but records are available. The dealer has attempted to repaid more than 4 times with no success. Warning lamps/messages? Y
