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.

problem #2

Jun 282015

Mountaineer 4.6L V8

  • Automatic transmission
  • 150,000 miles


On shooting spark plugs from the cylinder head while driving ...Does this sound normal or realistic! NO! This should never have happened let alone the frequency of it being reported on this website and others. It has now happened on two different cylinders on my vehicle. In addition to the intake manifold being replaced after 100,000 miles.

My #2 Spark Plug Shot out destroying the coil pack and busting the Fuel line. Thank God I was Parked and also as soon as I heard a problem, I turned the truck off. Now I have to fix a problem Ford knows about?? They never fixed it? I could have been driving with my kids and we could have died from this and possibly killing others along with us. This truck has to Go.
