Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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.
