Since we have this vehicle the heating system fails to work properly. We have repeatedly had the dealer and a G.M. representative try to repair this problem. After their attempts the system still doesn't operate correctly and now I am left with a defective air conditioning system that only works sometimes. I am hearing from other people that know who have this vehicle and the Chevrolet version the trailblazer that they have very similar problems. In the wrong circumstances not having heat/defroster working properly could be a safety hazard, yet this fails to become a recall or alert to drivers. As far as the A/C problems my son actually got heat stroke in the back of the car on a very hot day due to the fact that only vent windows open in this area and unless the vehicle is in motion it becomes very hot in the third row of seats in this vehicle if the air is not working correctly. G.M. should fix these vehicles! I have reported my problems to the better business bureau and I am hoping to return this vehicle to G.M. early. This car has also had numerous electrical problems with the radio. I feel that since they tried to fix the heater they have screwed up something else in the electric since they had to reground the whole system and this ground has already had to be reground due to the fact that it disengaged itself from the vehicle, doesn't sound like a safe repair to me.

The 2003 Envoy we purchased gave us numerous problems, including a number of the ones other owners mentioned here, like the glass liftgate that does not operate properly, various electrical problems, but especially the outside rear view mirrors that move on their own no matter how many times they were supposedly fixed by service technicians. They do not stay in the position we set them in, and the fuel tank leaking is very dangerous as well as inhaling freon because of malfunctioning A/C system. Why is GMC doing nothing to solve these problems" I can't understand how they are getting away with this seeing that so many owners are having the same problems. What do we have to do to get some help"
