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.

F-150 4WD 8-cyl

  • Automatic transmission
  • 63,000 miles
Truck was parked overnight (no problems). Next morning, I started the truck. It sounded like a lawnmower trying to start with a loud "popping" noise. Smelt raw gas vapors coming from the top of the engine. Took to Ford to fix. They quoted me $3200 repair job by replacing a cylinder head. I refused and took to a (farther away) trustworthy mechanic to put a thread insert into spark plug hole and use a helicoi for approx $400. Ford refused to do thread insert repair, and wanted to sell me same part that broke in the first place.
