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.

2003 GMC Envoy XL Owner Comments

We bought this car used. Well before we bought it, they had the A/C fixed, due to it not working properly. Well the rear A/C and heat still do not work. Sometimes it comes on, and other times it does not. It does not give out heat at all in the rear. This is a real issue for us and many others with children. I have read plenty of other reports stating the same or very close. In all in all, this should be recalled and fixed. These cars are way to expensive to have this issue and not have GMC step up to the plate and fix their issue.
