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.

I have been reading many of these post. I can't believe all of the things that have also happened to my Envoy. I have had my back window blow out while driving, thank god that both of my kids that were in the back seat were not hurt, they were just scared and still ask if it will happen again. I also recently just had to have a piece on the gas line fixed which was almost $900 money that I didn't have and had to borrow. I am still paying it back. Now as for last night my low beams are not working, I bought new bulbs and that didn't work, so it is back to the mechanic. Oh and I have a check engine light that goes on and off. They really need to get on all of these things. It would be nice to have the car working the way it should be. I may just print these things up and bring to the GMC shop and see what the can do about it. I mean I really to love my SUV but this is crazy. I am now kind of scared to have my kids in the car.

The back window on my GMC Envoy 2004 exploded when my son was closing it. Thank goodness the glass pieces hit and cut his forehead and hand and not his eyes!

On a cold cleveland Ohio day, I started my 2004 GMC Envoy and turned on my rear defrost, and about 5 minutes later my rear window just exploded! I was on the highway, and the sound was like a gunshot, and it nearly caused me to get into an accident, but I managed to pull my car off the road safely.

I have 2004 Envoy have had problems with alternator. Started about 6 months after I bought the Envoy had I replaced 3 times then started having problems with back seat window on passenger side not rolling up. Then my girlfriend had a flat on side of road and could not get spare down I had to go out and cut the cable that holds it up. That is a unsafe thing to do on side of hwy should not take 45 min to get spare down. Headlights dim and brighten gets dim enough that makes hard to see.
