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.

If I left the engine idle more than two minutes it would not pass the state emissions test. Now the emission light came on and it will not go off anymore. Almost got an accident vehicle will not drive over 20 mph anymore. I must have the same problems of thousands of other people. I was told I have to change the heads on the engine because of poor quality cast iron heads that was used for like three years. My Ford truck is one of these years they had the issues. Now I have to spend thousands of dollars fixing it this is nonsense with the low miles I have on it. These Ford should be recalled because of the safety issue. I have taken such good care of this truck and it still looks like brand-new I have to fix it! please help!!!

The contact owns a 2004 Ford Ranger. While the vehicle was stopped at a red light, the check engine warning light illuminated and the vehicle started to idle independently. The accelerator was depressed and the vehicle failed to accelerate. The failure recurred numerous times. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 125,000.

This complaint is regarding the very common problem with the 3.0 V6 motors that Ford produced known as the "valve recession" Ford released over 200,000 vehicles with these faulty cylinder heads. Ford is aware of this problem as they sent out a tsb (service bulletin) regarding this issue but yet they wont recall this problem.
