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.

There is a rattling, banging noise coming from under the hood. It only did it at first when I was slowing down with and without the brakes. It sounds as though the car is falling apart. I took it to Ford and they told me they heard the noise but it was nothing mechanical and they didn't know what it was coming from. They told me they checked all of the parts under warranty and it wasn't that. They told me that if I wanted them to continue to look for the problem, they would have to charge me by the hour. The car started making the noise about 6 months ago. It will go away for a few days and then come back worse. Now it does it when the car is stopped also. No one can find the problem.

The main problem is the transmission failures. It has gone out three times all in the same manner. The car in bone stock and only has 13,800 miles on it. The third time a field district engineer supposedly examined it and said the the parts and workmanship appear to be fine with no flaws and declined my warranty claim. I have been through the dispute settlement board and the ks attorney general with no positive outcome. I don't understand this action especially since I work for Ford(Kansas City assembly plant)I have researched this problem and found out that there weere problems with the '01 transmissions as per the technical service bulletins, tsb# 14879 NHTSA# SB620176, so it appears that dearborn assembly and Ford know of this problem but yet I'm still getting resistance"??????????"
