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 Owner Comments

problem #1

Feb 232010

Envoy 4WD 6-cyl

  • 118,000 miles


Throat of gas tank leaking on a 2003 Envoy. Reviewing internet, found many similar problems on the Envoy's and stated in 2007 that NHTSA was investigating. Mechanic stated very unusual to leak in that spot. Also, have replaced both head light sockets due to burning up. Have talked to many Envoy owners with the same problem. When bulb burns out and the recommended bulb is put in place the socket and wiring gets so hot that the socket is charred and is no longer functional. Wires have to be cut and a new socket wired in.
