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 #4

Sep 262016

F-350 Lariat V10

  • Automatic transmission
  • 133,003 miles


Driving along heard a noise then a louder noise pulled over to find a plug blew out and took the threads with it:(

problem #3

Nov 122009

F-350 Super Duty 5.4L

  • Automatic transmission
  • 50,000 miles

This problem has occurred many different times. Very disappointing. I have always been a Ford guy and own two of them. I love them but the maintenance is too expensive on them.

problem #2

F-350 XLT Super Duty Triton V10

  • Automatic transmission
  • 106,300 miles

One out of 10 spark plugs ejected (with great force!). Now wondering when other nine will explode (have read accounts of blowing right through the hood). Read one article stating that Ford Triton engines are blowing out spark plugs like sunflower seeds!


problem #1

F-350 XL 5.4L V8

  • Automatic transmission
  • 139,414 miles

I believe Ford should have at least made customers with Triton Series Engines aware of this problem. I was not aware this spark plug ejection defect was affecting Triton Series Engines. If this was known a owner could have been checking spark plug torque on all cylinders every six months,or more often to make sure that the spark plugs were not working loose.This could prevent much damage to Triton Series Engines.

This seems to be a engine or engine cylinder head defect, which I feel Ford Motor Company should be working on locating the cause of this problem. I also feel should work on locating a good "SOUND" fix for this problem.
