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.

Continued electrical problems with 2002 GMC Envoy. Such as on-star telephone along with radio/cd player, all four doors failing to lock or open including the back hatch. Service air bag light and engine check lights coming on. Reprogram engine/transmission module, also telephone antenna replaced, short in wiring located due to rubbing/pinching during construction, replaced wiring harness. Hundreds of dollars required to identify short in wiring. Transmission operates sluggish until warmed-up vehicle feels as if the brakes are on until it has moved several blocks.
