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.

Started truck heard a loud pop engine running rough checked, spark plug blew out destroying coil pack now called Ford dealer they said no recall checked on internet noticed a lot of people same problem. A lot money to repair. I had just got back from a 600 mile trip if this had happened during trip would have cost me up to $40 to get on road again, this should be a recall! and if I get it fixed I will have to get rid of it because people are complaining 2 or more plugs are blowing out and I can not afford the fix.

While driving my 2001 Ford F150 down the highway, a spark plug blew out of the head and damaged the ignition coil. Gas/air mixture was sent into the engine compartment, and if the plug had not damaged the coil, it could have ignited the gas. The fuel line is also just above the pug, and could also have easily been damaged.

The contact owns a 2001 Ford F150. The contact stated when starting the vehicle the engine would exhibit a continuous increase and decrease in engine rpms. While driving at speeds of at least 20 mph, the engine would idle tremendously loud and the check engine light illuminated on the instrument panel. The vehicle was taken to a local mechanic he performed an oil change. The failure persisted and the vehicle was taken to a second mechanic. The mechanic replaced the mass sensor however; the repair did not correct the failure. The mechanic then advised cylinder three had misfired. The failure had not yet been corrected to date. The failure mileage was 40,000 and the current mileage was 62,052.

Ford F150 spark plug # 8 blow out while driving to work. There were noxious fumes that eventually become very strong. I have read numerous complaints about this and feel that this must be a safety hazard due to obvious raw fuel, heat and potential sparks.

2001 Ford F-150 lariat..5.4 engine. Multiple spark plugs self extract..after 50,000 miles, creating possible fire hazard. No warning when it will occur. This happens in spite of routine normal maintenance being performed. When the plug pops out it also breaks the ignition coil tab for this cylinder thus making the cylinder inoperative with the possibility of raw gasoline/ethanol being ejected next to a uncontrolled spark from the loose coil. Very dangerous, especially with my wife and kids in the vehicle. There has been no notification from Ford of this possibility. This has happened to at least a few dozen times to vehicles in my local area. In fact, it must be a frequent situation because there are after market repair kits.. heli-coil installation (not a permanent repair). The repair from Ford is to replace the engine heads...a $5,000 plus repair cost if past the warranty period. Ford will not provide any satisfaction.

I had an original spark plug blow out of my Ford F-150 V-8 Triton motor while I was driving on the freeway. It made a loud pop noise and then I seen a flame I pulled over right away and shut off the truck and called for help. Thankfully I was not hurt and the fire went out and did not burn the truck to the ground. Ford refused to fix it they said it was not a lubricated part and my warranty didn't cover the $2000-3000.00 repair. It is a defective design and they know it but are not allowed to fix it under the warranty's.

I own a Ford F150 trition truck in may of 2008 I blew my first spark plug while driving home. I took it to a local dealer, and the service department informed me that it was a default in the design of the engine and that Ford would not cover the approximate cost of $700. Four months later, I threw another one while simply starting my truck in a parking lot. I paid another $700. It has been three months. On christmas eve, while pulling out into traffic from a complete stop, I threw my 3rd. Spark plug. This is a defect!
