“The speedometer, gas gauge, and oil pressure gauge first started fluctuating then eventually stopped working completely. The drivers door panel has completely went out. It smelt like something was burning but there wasn't a fire. I've had both situations checked out and the mechanic states this is very common in the envoys and trailblazers but it is still at my expense.”

“While driving on the highway at 65 MPH, the third row floor got really hot and my children were saying their feet were really hot and we smelled something like plastic melting and my 15 year old cousins boot melted and the carpet melted and you can see metal. Once we arrived home the blinker stayed on and did not shut off until the battery died. Just before this happed the vehicle lost power and my husband had to put his foot on the gas all the way.”

“I was driving down the road when the car shut down everything I was scared because I had traffic right behind me going 45mph and then they car would not run again. I was right in the middle of an inter section at hall road and 59 it was the scariest thing that has happened to me. I bought this vehicle as a used auto and I'm not sure if the emmission system ever got changed and this happened once before and the dealer said not to drive with my house keys attached. I had to get the auto towed home.”

“Erratic speedometer problems on my 2003 Gmc Envoy Xl. It has been acting up occasionally for several years, but now it sometimes will totally malfunction and either bottom out at zero, or register too high, it is just not working properly. I have done some research and found that this is a common issue for Gmc vehicles of this time frame, and envoys are one of the worst.”
