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.

My Reduced Engine Light and Service Engine Light have been on for six months now. We have put over a 1000 dollars into it. Everyone has told us to replace the fan clutch, pedal, electrical, computer, etc. Well we have and it is still not working!!

so a few weeks ago or so my abs light would turn on and off while I was driving for no reason. Then a few days ago when it came on my car just turned off! I restart it and it just does it again moments later! When it turns off it acts like it has run out of gas but I have over a half a tank! When I did put 10 bucks of gas in there it ran good for about 10-15 miles and then it did it again! Now I am stuck about 20 miles from my house with this POS! HELP!!!!!!!!!!!!!! I bought this car 2 years ago for 25,000 dollars and I have put a new engine in it and literally any other part u can think of... starter ,alternator ect. The cd player does not work the air and heat only work on level 4 and it only stays cold or hot for like the first few minutes! Now I am too poor to take it to a real mechanic HELP!!!

Vehicle shuts down on the highway (5 times). Problem first occured almost one year ago. (70 miles an hour/car dies) I was stranded twice on the side of the highway. It was determined that it was a bad oil pressure sensor. Last week happened again. (70 miles an hour/car dies) It was determined that it was a bad accelerator switch. 4 days latter.... dead on highway...70 miles an hour. Car is at dealer again. 900 miles remaining on warranty. I am afraid to drive my car.
