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.

Impala 3.4L V6

  • Automatic transmission
  • 63,007 miles

dealership had car for 2 days, told me I had to pick it back up and turn in

loaner, stated the computer did not read the problem and they could not

recreate the problem. Picked car up on 11-30-07 and broke down on

12-2-07. I am tired of the service dept telling me they cant find problem

and I am tired of being stranded, for a female this is not acceptable.

problem #2

Impala C41099

  • Automatic transmission
  • 65,000 miles

I am pissed off my car is not even paid off yet and I have replaced my ignition 2 times now come to find out it was the passlock that my vehicle is equipped with. So my car thinks I am stealing it and will not let me start my car. I can not pay anymore to have it fixed so if anyone knows what I can do that would be great. I thought maybe the problem was the aftermarket CD and speaker I put in my car. SO my boyfriend is trying that to see if that fixes the problem.

This has happened several times since purchased on 5/19/07 and can not find solution with dealership to the problem. I am tired of being stranded for 1-3 hours each time the car wont start.
