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.

Since last year I have had problems with my car when it is on the road specifically going up a hill it would lose power and it slows down and then it turns off while running. Which is very dangerous because sometimes the car behind me come very close to crashing against me. We took the car to a GM dealer where we bought it they could not give us an answer we have taken the car to 6 repair shops and no one knows what is wrong with the vehicle we have change the tps sensor, the spark plugs, map sensor, new battery, we have cleaned the fuel injectors several times, we change the transmission fluids, we change the pump gas completely, we have changed the ignition coil.we have changed the timing belt twice since we have the car. And the car is running worse now because it stops not only in a hill but on a flat road too.
