The contact owns a 2006 GMC Envoy denali. The contact stated that the vehicle failed to start and all the warning indicators illuminated. The contact mentioned that when the vehicle would start, it would cut off immediately. The vehicle was taken to betten baker Chevrolet Buick GMC (14120 northland dr, big rapids, mi 49307 (231) 629-4340) where it was diagnosed that an electrical failure was found, but the dealer did not know the exact cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to NHTSA. The failure mileage was approximately 126,000.
Engine suddenly stopped running, placed shift lever to park position. Engine would not restart. Transmission was now locked in park, causing inability to push vehicle to safety. Repair by GMC dealer involved repairing electrical short in factory wiring under dashboard at the firewall, in the area of the brake booster mount. Apparent cause is improper routing of wiring at time of vehicle mfr, causing abrasion of wiring over time.
Engine wouldn't crank at times. Starts normally when it does. After about a week of having this problem I took a the car in for service. Diagnostics determined the ignition switch was bad and should be replaced. I had the ignition switch replaced 14 months and 6070 miles prior to this incident. They replaced the ignition switch. The part was under warranty but diagnostics and labor was $220. The first ignition switch failed at 65-70 mph on the freeway. I understand that gm has recalled ignition switches on several models but the Envoy is not part of that recall. Obviously my vehicle has the same problem as the recalled vehicles, why is it not part of the recall? this is a very dangerous problem. Since the rest of the electronics are connected to the ignition I have no safety equipment such as air bags. If I would have been in an accident, it could have been fatal.
