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 Chevrolet Impala Owner Comments

The speedometer on my car has decided to read whatever it wants and it will stop at whatever speed. Now the temperature gauge has started doing the same thing. This started happening around 65K miles. Have found that this car has the same steppers in the instrument cluster that was on a recall for another vehicle. Have also found many other complaints about speedometer going haywire. This is a severe safety issue due to not knowing how fast or slow you are going in a residential area or on the highway.

While driving the car feels as if the transmission is failing, every turn you hear knocking and bumping, recently was told that the rack and pinion needs to replaced the car has only 60,000 miles. I have had it for 2 years and I have had several proplems. My ac works however only the passenger side of the heating unit works. The knock soud occurred immediately after purchase the dealer ship sad nothing was wrong with the car. I have a friend with the same vehicle and had the same issue with the knock and bumping fortunaely there car was totalled and they were not injuried at least they are no longer resonsible for this lemon.
