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 Lariat 5.4L

  • Automatic transmission

Its happened to me twice within 3000 miles. First time I was able to fix it myself. Second time not nearly as lucky. Looking at a few grand in repair costs. I've always been a fan of Fords but this issue has me seriously reconsidering!!!

problem #1

Nov 192008

F-150 XLT 5.4L V8 Triton

  • Automatic transmission
  • 130,000 miles

I purchased the vehicle new and had it service at the dealer exclusively. I really took care of this truck and liked it a lot.

At around 130,000 there was an explosion under my hood and a massive loss of power. After having it towed to the dealer I was contacted the next day and was informed that a spark plug blew out of the engine. I thought this was strange and googled it and long and behold it was all over the internet that other 5.4L did it too 1999 to 2002 I think??? Have to check me on that; some called it a head problem other a spark plug problem...

When I got it back I sold it right away... I now drive a 1999 Ford Explorer 5.0L v8 302 mustang engine. I found it with only 38,000 original miles on it. Got 5000 for my old truck as a trade in paid 3000 difference; no payments. :-)
