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.

In June 2010 I was driving on the interstate 90 West toward denver co. The terrain was steep and winding and due to heavy traffic the pace was fast. The traffic ahead of me began slowing and I began to slow by steady light pressure on the brake pedal. My brakes heated up fast and I found myself without breaks for a short period of time due to the rotors feeling as though they were warped and the front end started vibrating. I down shifted to 3rd. Gear but that was not enough to slow me enough so I downshifted to 2nd and this still was not enough to maintain a downhill speed to keep from having to use the brakes. Finally I shifted to !St gear to maintain the safe speed that I needed. The problem seems to be that the car freewheels so excellent that even on lower grades as experienced in the carolinas in October when we were there the car is almost impossible to gear down so as not to overheat the brakes when trying to maintain posted speeds in mountainous country. I discussed this with solomon Chevrolet in dothan where I get the car serviced and the dealer from whom I purchased the car. They had no suggestions but assured me there was nothing they could do dealership wise to help me. I feel it is a very dangerous situation which does not surface unless you drive in the mountains.

2009 Chevrolet Impala, bought in July of 2010 with 18,000 miles on it. When I stop to park the car, my foot is on the brake, I put the gear shift into park and when I take my foot off the brake the car will roll forward 8 to 10 inches. It also does it in reverse but only a 3-4 inches. Happens about 1 time in 5. took the car to the dealer, it didn't happen to them and was told that was normal.
