Sierra 2500 8-cyl Diesel

Letter on behalf of constituent requesting assistance in difficulties dealing with GM regarding a manufacturer's defect in the electrical circuits in his 2004 GMC K2500 pickup truck. The consumer stated the vehicle stalled for no reason while driving 70 mph on the highway. He lost all electrical circuits, power steering and brakes. After 45 minutes, the vehicle restarted. The next day, the consumer took the vehicle to the dealer, where the mechanic found loose pins on the wiring harness connectors at C107 and C108. The mechanic stated he didn't believe that was the cause of the vehicle stalling, but they were loose. Since, the first failure, there have been 10 more failures. The consumer took the vehicle to another dealer where it has been since July 2, 2009 without a specific cause being found.
