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 vehicle was repaired. The approximately failure mileage was 114,000. Updated 04/09/13 the consumer stated the first time a problem occurred, his daughter was driving and she noticed the vehicle would no longer accelerate properly. The vehicle was taken to an independent mechanic, where it was determined the egr valve, had a hole in it. Ten days later, his daughter experienced the same failure and once again, the vehicle wa taken back to the repair shop, where it was determined the catalytic converter had most likely developed an obstruction that caused a large amount of pressure back in to the exhaust system, which caused another hole to blow out the egr valve. The consumer received an estimate of $2500 for the catalytic converter system.
