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.

While driving rpms go up high, idle will not drop. Vehicle accelerated suddenly and unexpectedly without warning. Car drives over 40 without foot on gas. Hard time braking because engine is too high. Has been going on since had car. Dealer adjusted cable and didn't work. Almost went thru dealer wall when bringing it in for repair. Is in repair shop again because problem was not fixed. Car is unsafe and had near collisions.
