“While vehicle was running, a burn smell eminitting from driver side door. Immediately brought vehicle to local repair shop for repair. They diagnosed the smell and window failure to the driver side master switch. The repair shop used original replacement part. This month again, my switch does not work and windows currently are not working. Frustrating because Gmc accepted no responsibility. I still have the old switch and receipt and should be eligible for reimbursement for the labor and replacement part cost. Thank you”

“2006 Gmc Envoy Xl. Since the car was purchased there have been repeated issues with the service lights. This problem has occurred repeatedly through 2012 where a variety of lights come on. Some stop the car from starting... In 2006, service stabilitrack consistently comes on along with 3-56 other lights at the same time. I've been told the connectors are dirty, that I needed a battery replacement which was untrue. Other times the car has gone for service, noone really has the right fix. There is something wrong with all the sensors.”

“I have experienced a check engine warning light display on what is now the third time for the same issue. The diagnostic code for each of these three check engine light displays on my 2006 Gmc envoy was for a problem with the fuel tank level sensor in the fuel tank. The first time I experienced the problem, GM replaced the fuel tank level sensor unit under warranty. I experienced the same issue in the summer of 2009 with approximately 65000 miles on it. I replaced the fuel tank level sensor myself to correct the problem. …”

“While driving I turned on my left blinker to turn. The wiper came on and it sprayed windshield washer fluid. I put it back into the neutral position and they kept spraying and would not stop. I pulled over turned the vehicle off and back on. The wipers came back on immediately and continued to spray wind washer fluid. Then my speakers started to play a distorted sound. I turned off vehicle again about 4 more times and every time the wiper blades and spray came back on. I had to stay parked on the side of the road for about 10 minutes then they stopped. …”

“I own a 2006 Gmc Envoy Xl. Last may of 2009 I was driving on us state 30 with my children when the driver's side door start smoking vigorously without warning. Just as this happened the vehicle shut down in the middle of the highway while I was driving. I was able to restart the vehicle after a few attempts and remove it from traffic. I then tried to open the drivers door to get out (the handle its self was not smoking) and it would not open. I climbed into the passenger's side and manually opened the door, got out, then removed my children also. …”
