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.

Check engine light is on. According to tests it is the result of a defective throttle position sensor. The light will stay on for a couple of days and then go off for a couple of days creating a error message that something is wrong with the engine. With it going on and coming off it is now difficult for me to get my inspection completed with the sensor reading not being accurate.

Driving along street and all engine lights went out and engine stopped. Lost power steering and had to fight to get over to side of street and safety. This has happened 3 times since the first time each time the ignition switch required replacement.

Driving on highway in rush hour traffic @ approximately 55mph. Suddenly noted loss of power without warning, with no check engine lights on ( until managed to get car to side of highway and put in park, then multiple icons lighting up). Had towed to dealership, they almost immediately told me a faulty ignition switch was the most probable cause. Of note, car went on to have ignition switch needing replaced @ 74,218 miles. This time I was again driving on the interstate at approximately 65mph, but this time suddenly felt car losing power, and no check engine light once again. I managed to get to berm, put in park, with multiple icons then lighting up, as if "shorting out". Shut ignition off, took multiple attempts to restart, had towed. -at 105,162 miles, again replacement of same part, after having fully lost power without any warning this time, though this time occurred while going down my driveway. ********of note, I do not have a "heavy" key ring nor was there jarring from rough roads on any of these 3 occasions.

Tl* the contact owns a 2008 gmc envoy. The contact stated that the check engine warning lamp illuminated on the instrument panel. The vehicle was taken to the dealer and they stated that the seal that was on top of the fire wall was damaged. As a result, the water was sipping into the engine compartment and was getting on the coil packs and the plugs. The vehicle was not repaired. The manufacturer was not notified. The failure mileage was 59,000. The VIN was unavailable.
