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.

2004 GMC Envoy XL Owner Comments

Envoy XL 4WD 6-cyl

  • Automatic transmission

While driving at 35-40 mph, after exiting the highway, (I-75) my truck just slowed all of a sudden, almost to a complete stop, no warning. And started jerking. I was almost rear ended. My truck started rattling, and clanking, and I had to have it towed. I was told by the dealership that my front carrier had thrown a bearing, (font differential) and the housing was broken. I was also told that it would be $3,286.53 to have my truck repaired. Upon further research, I learned from a friend that the same problem had occurred with his truck six months after he had purchased it, and that over 450 of these same parts had to be ordered in 2004 alone.
