We have a 2008 Envoy. We bought it brand new in 2008. The ignition switch has quit us 5 times. We usually have some warning. The first 3 times , the check engine light came on but I could eventually start the car and drive it to a mechanic to be checked out. The 4th time we were heading out of town, check engine light came on, my husband pulled over to side of the road and car quit. Would not start, had to tow it to mechanic. This last time, no warning, just quit as I was driving home. I was able to get it started after sitting in the middle of the street for 30 minutes or so, drove it home, quit again and had to tow it to mechanic. I am afraid to take it out on the highway by myself. Afraid this vehicle could cause a wreak, and possible kill or injure us or others. There aren't very many miles on it, so it is not a worn out vehicle.

On Saturday 4/2/16 our area eastpointe (detroit) mi a snow storm was in the area. As I entered my vehicle snow fell on the drivers side window door module. I bushed off the snow and proceed to drive my vehicle. After about 5 minutes while on I-94 at 70 MPH all four power windows started to go up and down. After two or three times of this action all four windows stayed in the down position. At that time I noticed sparks and smoke coming from the switch positions on the module. I pulled over to side of the expressway and since this module is just a snap in, I removed it and disconnected the cables. Since the passenger side window was conveniently down and module was still smoking and emitting sparks I tossed it out the window into the snow. After about five minutes I retrieved the module and drove the secondary roads back home. Part number on the module label is 25811557. …

Had problems with the heater's blower motor not blowing or sometimes blowing but not on every speed. Looked up issue on youtube and found many videos of the same issue and the videos showed them having to replace the heater's blower motor resister. As the resister was being replaced, we noticed the resister was melted onto the plug it plugs into and the thick red wire was also melted. Resister got replaced and the blower speeds all worked again. Shortly after installation of the new resister, the number 5 speed failed but all others continued. Three months later, the resister failed. Exchanged and replaced the resister again and worked on all speeds but 5 again. Had a smell to it while in use, we got use to it and thought nothing of it anymore. …
