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.

Driving home in my 2001 F150 supercrew and when I turned on the A/C fan, smoke started coming out from under the glove box. I pulled over and look under the box and noticed the connector to the fan speed pack was burning. I blew it out before it did any further damage, then unplugged it. No issues since then.

My 4.6L engine on my 2001 Ford F150 pickup truck needed new spark plugs. I have changed plugs on many motors before so it is not new to me. I read the service manual and learned more about this particular model by reading information off the net. I was very careful and did everything the service manual and net info told me to do. Even so, the very first plug I removed from the engine block broke. The porcelain and hex nut came out in one piece but the bottom threads and ground electrode remained in the engine block. I went back to the net to search for solutions to the problem only to find that more often than not the spark plugs on these models will break apart when removing them. I believe this falls under the category of a recall. This will be a costly repair that I cannot do myself and I don't believe Ford can justify this many plugs breaking.

I own a 2001 Ford F150 pickup. I've had to change a coil (above spark plug) on this truck several times (at least 5 failures) since I've owned this truck. When a coil goes out the truck misses a lot and at times when you slow down to turn a corner the truck will die, causing me to brake to an immediate stop because the power stearing goes out. Very dangerous.

I have a 2001 Ford F150 with the 4.6L Triton. Driving home from work on the evening of April 27th, im at a red light. As soon as it turns green I push the pedal to go. Out comes the spark plug from the block. I have read numerous complaints about this issue on the internet. I cannot believe Ford has not issued a recall over this. Not only is it dangerous, but its a silly problem to have. I have had 5 estimates to fix this problem all over $2000. There's no way I can afford this, I am looking for a class action lawsuit to join. Very disappointed in Ford and when I get this fixed I will never own another Ford vehicle.

One morning upon starting my 2001 Ford F-150, I heard a loud pop and knocking coming from my engine compartment. The #3 spark plug on the passenger side, shot out of the cylinder head and broke the #3 cylinder ignition coil, stripping the threading on the cylinder head. Ignition coil, spark plug, and steel insert threading were replaced. Mileage = 124515 5.4 V8 this is appears to be a well-known problem:"section=news/7_on_your_side&id=4757786"Ford-spark-plug-problems---spark-plugs-broken-and-blowing-out&id=1107803.

The contact owns a 2001 Ford F-150. The vehicle caught fire while parked outside the contact's place of work. The fire department was notified, but did not state what caused the fire. The fire burned the motor, created a hole through the hood of the vehicle, and scorched the entire dashboard. The windshield glass burst into pieces and the vehicle was towed to his residence. The Ford dealer filed a case and followed-up with the contact within 15 business days and informed him that someone would diagnose the vehicle. The contact was also informed that there was a recall for the cruise control. The VIN and NHTSA campaign id number were unknown. The failure and current mileages were 197,000. Updated 04/17/09.

2001 Ford F-150 blew out a spark plug for the 2nd time. Caused the truck to go off the road since it immediately lost power while going 65mph. This is the 2nd one that has blown and will likely cost a few thousand dollars to fix. There is a forum on Consumer Affairs with hundreds of people with the same exact problem with their Ford vehicle. The website link is if you would like to check it out.

I own a 2001 Ford F 150 w/ the 5.4 Triton engine, while I was backing the truck out of a restaurant, the engine made a loud pop. I took the truck to a Ford dealership...they told me that the engine blew the # 3 spark plug out. The service department told me that this is a common problem with the motor because of bad designed heads. They advised me that I would be better off with a new engine at the cost of $4800. I pulled up a site on the internet that states that there have been thousands of complaints with the same problems. I feel like Ford should have a recall on this engine.

On multiple occasions I have been driving and heard a loud bang and felt the motor starting to shake and loss of power to the vehicle. Upon inspection, I have noticed the coil pack of my 2001 Ford F-150 sitting on top of the motor. I have replaced two coil packs twice each. It is getting costly to repair as it costs $50 per coil pack. I have retapped the holes but the problem keeps occurring. I am a divorced father of a 2 year old son. I can't afford to keep repairing the problem.

F-150 8-cyl

  • 150,000 miles
My 2001 Ford F-150 blew a spark plug out of the 7 head on 09/30/2008. The truck has 150K on it. I bought it new in 2001 and have always maintained it. I went out to go to work in the am and the truck just roared when I started it, I found the spark plug on the driveway the threads on the plug were completely in tact. Took it Ford service and it will cost me $2500 to fix with no guarantee. I have found that this is a really common complaint from owners of V8 Triton engines. Ford needs to do a recall on these vehicles. My brother-in-law is an asi front end mechanic for Ford and he says he has seen a lot of this problem. If he didn't live in denver I would have him fix it. My family has always driven Ford products. My father was an engineer for Ford in detroit. But, I feel that because Ford will not stand behind this problem that maybe it is time to switch loyalties. The service department at the dealership displays a so- what attitude. I requested a factory rep to look at the truck and they said either fix it now, or move the truck off their premises. The consumer has no rights anymore.

F-150 8-cyl

  • 90,000 miles
My 2001 Ford F150 blew a spark plug right out of the aluminum head on 8-17-08. Vehicle had about 90,000 miles on it. It is a common and repeating failure of the 5.4L V-8 engine and Ford will not acknowledge it as a problem. I opted for the helicoil replacement option ($640) over a complete new head ($3000). Ford will not pay for any of this even though it is their design flaw. Later models have been changed to correct this problem. If it was not a problem then why was it corrected?
