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.

Truck(83000 miles) was parked in driveway. Went and started and the truck began to sputter and shake and the check engine light came on. Truck would not accelerate and I took to dealer. Began to shake even more and lose power. Problem was timing chain tensioner failure which caused failure to engine. Engines needs replaced. Dealer explained that this can happen at any time and usually causes major engine damage and failure.

F-150 8-cyl

  • 100,000 miles
We took our vehicle in for service immediately after we experience the engine missing. The service center diagnosed the problem would be corrected by replacing the ignition coil, plugs and wire boots. This seemingly simple service job has literally turned into a nightmare. After almost 4 weeks our vehicle is still in the shop. In the process of changing the plugs, 2 plugs broke. The dealership needed a "special" tool to remove the broken plugs and had to order it. When they got the tool, the still couldn't remove the plugs and said they would drill them out. And then - the biggest blunder of all happened - while they were drilling some pieces of porcelain fell into the engine and scarred the cylinder(s)which could potentially cause the entire engine to fail. Now we're being told because of this we need to replace the engine!! each time they called it was about something else going wrong and more money!! we're loyal Ford customers! these adtl repairs should not be at our cost!

I want to preface this by saying that before this problem occurred I had my F-150 iat a Ford dealership in raleigh nc two says before because the vehicle would randomly shut off when I was driving it about 600 miles before the extended warranty was up. They said they could not find anything wrong with it so I was forced to take the vehicle back I was driving home from my parents house in Ohio on christmas day. As I was heading through Virginia to North Carolina I heard a noise coming from under the hood. I stopped to see what it was and eventually found out that the spark plug had blown away from the head. Apparently this is a common problem with this make and model vehicle along with many others. After horrible customer service I was forced to pay almost 3500 dollars in order to get my truck back. Ford said that they could not do anything about it.

  • Automatic transmission
  • 44,000 miles
The contact owns a 2004 Ford F-150. While driving approximately 50 mph, the contact noticed that the engine warning light illuminated on the instrument control panel. The power began decreasing simultaneously and prevented the vehicle from traveling above 35 mph. The dealer replaced the coil pack and spark plugs in the number five cylinder. The contact heard a knocking noise when he started the vehicle and the failure recurred. The dealer stated that the spark plugs blew out of the aluminum head. They also stated that there were only five threads holding the plugs to the aluminum head, and, even if they made the repair, the vehicle could still fail. The manufacturer would not assume any liability. The failure and current mileages were 44,000. Updated 03/25/08.

Out of the blue the truck just starts shaking, never know when or where. I have to pull off road and shut it off, wait a bit, then start and leave and seems to be ok till next time. It has 37,800 miles. Last time on I-94 at 65mph it scared me to death it started shaking so bad. I also had a 2005 F150 that did this. Its not the tires, or engine but I think the drivetrain. Very bad safety issue as I am finding I am not alone with this problem. Someone needs to make Ford admit what this is and fix these trucks.

On June 11th 2007, I drove my 2004 Ford F150 pickup truck 12 miles to drop my dad off at his house. I came straight home. I parked the truck in front of my home at 5:00pm that evening. It stayed parked for the night. At 3:20 am on June 12, 2007 my 2004 Ford F150 full size pickup truck burst into flames. It burned so hot that the firemen had a hard time putting it out. The police checked a camera that points down my street and it did not show anybody doing anything to the truck. It just spontaneous combustion. There were no modifications made to the truck, and all maintenance was performed in a timely fashion. I also have pictures of the truck if needed.

The contact owns a 2004 Ford F150. When driving 35 mph the vehicle stalled and was driving hard. The vehicle was taken to the dealer and the spark plugs were replaced. The dealer stated that the spark plug in cylinder five was broken in half. The current mileage was 53504 and the failure mileage 53500. The engine size, and power-train were unknown.

The consumer stated he had to take the vehicle to the dealer to be repaired and that a price was agreed upon. The consumer stated that his confidence had been shaken with Ford and an investigation should be done. The consumer provided the repair invoice. Updated 07/23/07

1) unknown events leading to failure, normal driving, events happened when I first turned on vehicle and during backing up.2) the engine raced out of control and lurched until ignition key was removed (it grabs the gas pedal from the driver like cruise control does) if someone or something is in vehicle's path it or they will be crashed into. Then the vehicle and 8 cylinder runs like its on 4 cyl and the air conditioner doesn't work. 3) taken to Ford dealer coastal Ford in mobile al, they rebooted computer but would not replace computer board, they said just bring it back for reboot if it happens again, diagnostic did not reveal reason for racing engine they were not concerned that if the events happened again an accident could not be prevented or the truck being destroyed which means it could not be taken back for reboot or how to prevent this event.I wanted them to replace the supposedly defective computer board (in my opinion that's the problem) old part still in vehicle.no damages yet but since I professionally bass fish, I could be run over, the truck might race into the water, or someone else and their equipment could be run over and if backing into the garage with a boat the house and boat could be damaged or if the boat trailer has to be dealt with the person behind the truck could be run over. 2004 F150 extended cab V8 engine truck is the vehicle. 6 events over the last 4 months (it just came out of some of its warranties, Ford dealer said the computer was warranted for 8 more years)

2004 Ford F-150 FX4 stalls while driving; it is as if the gas pedal no longer works. Had vehicle towed to dealership. They have had the vehicle for four days and state that they cannot find anything wrong with it. They state that the computer shows that it was run on "lean fuel", however it had a full tank of gas. Runs okay during test driving by dealership. However, stalling presents a safety concern. 8jb
