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.

problem #2

Envoy 4WD

  • miles
Mirrors 'wander' every time vehicle is unlocked, fail to return to settings creating an unreasonable danger to the occupants of this vehicle as well as other vehicles when changing lanes or merging into traffic due to lack of visability of the area behind the vehicle. Transmission failed on a slight incline with parking brake engaged and transfer case locked and in 4WD and transmission in park - vehicle began rolling backwards down the slight grade. There was a recall for this problem - campaign was completed at dealer, but fix is unknown to the owner.
