Tl* the contact owns a 2006 GMC Envoy XL. While driving at various speeds, the vehicle stalled without warning. In order to restart the vehicle, the contact would have to jumpstart the battery. Shortly after charging the battery, the failure recurred. The contact took the vehicle to the dealer who was unable to diagnose the vehicle. The contact took the vehicle to a certified mechanic who stated that the alternator needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 123,000.
While vehicle was running, a burn smell eminitting from driver side door. Immediately brought vehicle to local repair shop for repair. They diagnosed the smell and window failure to the driver side master switch. The repair shop used original replacement part. This month again, my switch does not work and windows currently are not working. Frustrating because GMC accepted no responsibility. I still have the old switch and receipt and should be eligible for reimbursement for the labor and replacement part cost. Thank you

On 2/15/07 I was driving to work at approximately 50mph when all of a sudden the steering went out, brakes locked up, all gauges went erratic bouncing from side to side and the heater started blowing cold air upon this happening I nearly went into a creek however struggling did manage to safely get the vehicle off the side of the road in a ditch. I had the vehicle towed to the local dealer when upon diagnosis the service manager informed me that the ignition switch had failed and all of the above components were tied into the switch. I at my own expense had the ignition replaced and the RPM gauge still does not work. I contacted GMC the very day of the incident to make them aware of this safety issue only to be bounced around to several different offices, none of which have made this safety issue a top priority. …

My headlight driver module fuse caught fire and caused a fire in my fuse box in which I had to use a fire extinguisher to put out. The dealership informed me that the fuse got hot and instead of shorting out and blowing the fuse it caught fire. Had I not been in my driveway my vehicle would have burnt completely to the ground. This imposes a major safety hazard. The vehicle has been sitting at the dealership for 3 weeks while GMC decides what they will do.
