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.

The car would accelerate and then stall out. The motor would vibrate like it was jumping. Hard to start die after putting into drive. Had to replace the transmission and converter in 2011, spark plugs and wires have been changed. The car has blown sensors a month after getting it out of the shop. Have spent over 6000 dollars trying to keep the car running and the same thing keeps happening.
