Three problems related to ignition module have been reported for the 2006 GMC Envoy. The most recently reported issues are listed below.
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.
One evening I was driving on the main highway and my inside lights came on. I pulled to the side of the road to check the switch but it was on auto. I turned it off but the lights stayed on. They were still on when I got home and parked turned off the ignition the lights were still on. The next morning my car couldn't start because it had ran my battery down. Another incident was my headlights went off one night while I was drive on the highway. I am also having problems with my gas gauge. My gas light comes on like I am out of gas. The last time I fill my car up with gas it hesitated. It didn't want to start. The light stays on when my car is full of gas. I smell gas. I sat at the gas station for an our because my car didn't want to start. The sound of my radio goes in and out. My lights continue to go on and off when driving or when not driving. One morning I got up to go to work, went to start my car and the headlights were on but the switch was off. I couldn't get the lights to go off when I got to work. They stayed on at least for 4 hrs. Sometime the lights doesn't come on when I put them on. I really have some weird things go on with my vehicle. I did get the module changed and they did some re-wiring in the door. One year before the module, I got them to check my car for a short and I was told from them that my wires were over heated. I paid about $900 to fix it. I strongly think it is a detect some wheres or something that would cause my wires to over heat.
Dear sir, today while driving my 2003 Envoy SUV (approx 40,000 miles on the od ) I was making a left turn onto a major highway. About 3/4 way through the turn the car accelerated full speed without my help. Since the roadway was wet (not raining at the time) the car sped and spun violently to the left and crashed into the concrete barrier separating the four lane highway. We ( my wife and I) hit the barrier with a strong impact but suffered no serious injury. (we were belted) this automobile is used as a towed vehicle as we travel the country in a motorhome. The car has a vary heavy and stout steel towing base plate on the front. The base plate was bent badly but it protected the car from serious damage I have been driving for some 42 years without ever having a chargeable accident. I have never experienced such a condition. If the barrier had not been there we would have collided with cars in the other lanes stopped at the red light. We realize that "sudden acceleration" has in the past been blamed on drivers. I assure you that this car took off at full throttle and this driver did not trigger such a response. Circumstances prevented this from being a major ta with injuries. I have no axe to grind and seek no compensation of any form. Now however, I am worried about driving the car without knowing what may happen. The acceleration stopped upon impact and I drove the car about a mile to my campsite without further incident. Please inform me if others have reported this condition and if there is a protocol to insure it won't happen again. Thank you, michael c. Mccoy.
