GMC Envoy shut down while driving. All power lost. Vehicle came to a complete stop just a few feet before an intersection. Dealer replaced ignition switch, due to "multiple codes stored in the ecm. " ironically, almost 2 years prior, same issue with the vehicle happened on the express way. We were lucky to be able to get to the side of the road before the vehicle came to a stop. Ignition switch was replaced during that incident as well. Two ignition switches have been replaced in the same vehicle over the course of 2 years. I'm surprised that this vehicle isn't part of the gm ignition recall!.
The SUV has shut off on me three times in the last 2 1/2 yrs (the time I have owned it. ) each time I was just driving on the city streets going about 30 mph. All of a sudden the car just shut off and all lights, etc just turned off. I am concerned wondering if perhaps there is a problem with the 2005 Envoy ignition switch as well? no, it was not the battery or anything to do with the servicing of the SUV. I take care of the vechicle and I don't drive 200 miles a month. I guess I am lucky that each time I was not gong fast and the SUV just slowed down and came to a stop, on the side of the road. However the 2nd time, I had 2 little girls in the car with me and it concerned me a great deal. Each time the SUV started back up and I was able to resume driving after about 2 minutes. What if I had been going faster ? what if I had been on a highway etc. If there is an issue with the ignition, please lets fix it before someone dies. I will make sure everyone in my family know about the shut off problems I have had with the car. Just in case something happens while I am driving it.

Speedometer failure ignition switch failure (multiple times).
There was ignition switch failure while driving the vehicle. The power steering and brakes gave out, the engine shut off, and all the lights on the dash came on. It resembled the car running out of gas without doing so. After I pulled off the road with great difficulties, I put the car in park and the vehicle got stuck in it. The engine would not turn over after this occurred and needed to be towed. There is no release switch which the tow truck driver said there should be so he could get it onto the truck, so the vehicle has to be drug with the wheels locked onto the flatbed and then pushed off in the same manner. We paid to have it fixed and it has now happened again 5 months later. There are many reports of this online and it is not just with the GMC Envoy denali it also includes the chevy trailblazer and possibly other vehicles manufactured by gm. There was one person online that said they keep spare ignition switches in the vehicle and the tools to swap it out because of how frequently it happens. The dealership replaced the part and it is not available as far as I know, because it was not returned to me. The vehicle was a 2005 GMC Envoy denali.
