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 stalled a few seconds after starting, then would not crank, only clicked. I had the car towed in for service. Technician checked battery. It was fully charged and vehicle had full voltage. Diagnostics determined low voltage out from the ignition switch. Recommended ignition switch should be replaced. I had the ignition switch replaced twice already. I have had to replace three ignition switches in three years at a total cost of $817. 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? The first ignition switch failed at 65-70 MPH on the freeway. 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.

I was driving on the freeway at 65-70 MPH. The engine lugged a little like it was running out of gas but the tank was half full. The engine resumed running at full speed. A few seconds later the engine shut off. I was able to coast long enough to pull off the freeway. But without power steering and brakes this was not an easy task. Once the car stopped I turned off the ignition and put the car in park. I tried to restart the car but nothing happened. I called a tow truck but the driver could not get the car to shift into neutral in order to put it on the car carrier because the shifter is tied to the electronics. Without power it does not work. He had to call for another tow truck to pull the vehicle in for service. The service technician tested and found low voltage from the ignition switch. He replaced the ignition switch. Diagnostics, part and labor $307. This is a very dangerous problem. If I was not able to move out of traffic I would have been a sitting duck in the middle if the freeway. Since the rest of the electronics are connected to the ignition I had no safety equipment such as air bags. If I would have been in an accident at freeway speeds, it could have been fatal.

Driving at 20 miles an hour and hear a crackling noise in driver door panel. Window rolled up on it's own, side mirrors began to readjust themselves and heated seat came on. When noise quit I had lost all control of panel controls. Called gm dealer to get it in for the recall on master switch and was told there were no parts or remedy from gm as of yet. Recall came out a couple months ago. Called another dealer and told the same thing. I called direct to gm and was told there was no solution at this time. I had no window control, car will not lock, side mirrors pointed down to ground so I can't use them. I called back and asked why a recall was issued when there were no replacement parts on a safety issue such as this. Kids can open doors, can't change lanes on highway do to mirrors and can't use windows. As I continued to drive the crackling came back and seat reheated, mirrors repositioned, and window tries to go down. I called again and was told I could set an appointment and would have to pay up front and then get reimbursed from gm. I told them I would not under any circumstances. They would review and get back with me in 24-48 hours. Nothing so far.this morning while driving in the dark the noise started again and I lost my headlights, black, nothing. Sitting at a stop sign today, car running and in drive, I lost all dash panel gauges for about 30 seconds. Car still ran and everything came back. Fearful of a wreck and having kids in the car with no safety locks. I can't manually lock hatch so I am at risk of an easy break in and I am in the medical field and travel with supplies that must be locked up. Never by another gmc something needs to be done!!!!

After exiting the interstate with speeds up to 65mph and before I could slow down to the to the current speed limit of 25mph the engine of my gmc envoy denali 2006 abruptly cut off. I steered to the curb to get out of the road of traffic with the first thought that I was out of gas; but I had a fourth of a tank. The gmc dealership first told me the ignition switch burnt out and my repair bill was $277. Several days later they called me and said the vehicle stalled again while they were test driving it. Now they say the ignition switch burnt out a module which would cost another $700. Total bill with labor and tax....$1059.57.
