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 #1

Envoy SL V6

  • Automatic transmission
  • 50,000 miles

Im in my mid 60s and had met my daughter and grandchildren at the mall. It was dark.When I started the engine to come home,it would not go into reverse gear and their was a horrible grinding noise. I was parked on a slight hill and the vehicle rolled backward so I was in the pathway of other vehicles. I was pushed out of the way. I continued to try to get it to go into a gear to no avail. I called AAA and sat there with the motor off until they arrived.When they arrived,the envoy started and drove as if nothing had happened. I figured that it was just a freakish one time happening so I forgot about it. Well, my husband and I went to lunch on Saturday05/10/08 and it happened again. I called AAA and as I was giving directions, I decided to start the envoy. You guessed it, it started up right away and again,drove as if everything was perfect Can anyone please help. I now feel very unsafe with this vehicle.
