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.

Engine surges without touching gas pedal while in gear

- Milwaukee, WI, USA

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

The consumer bought a used 2004 Ford F150 and has been experiencing a problem with the engine dying when applying brake pressure. This occurs in high traffic areas and at slower speeds in stop and go traffic. Took to a dealer and they performed eec diagnostic quick test and pinpoint test diagnostic ignition tests as well. As a result of those tests they replaced a mass airflow sensor assembly and reprogrammed the PCM. Has been to dealer on 4 occasions for this problem and dealer claims they can not find anything wrong with it. Contacted Ford manufacturer they had "joystick"or test stick installed in vehicle for 5 days in which consumer was unable to duplicate the problem at that time. This has happened 1 time since. Also on the dash there is a 4X4 high/lo light that illuminates on the dash when this occurs but the vehicle does not have 4 wheel drive. Dealer said they were unable to reset the PCM to correct this particular problem. This is still a problem, no recent repairs. Dealer can not duplicate the problem at this time.

Had to put 4 sets of brakes on vehicle since purchasing the car. The rotors were getting grooved so badly that vehicle pulls off the road. The consumer talked to Ford, and they ignored him. He traveled and saw this problem with several other Ford cars. Ford told him it was cosmetic. While on the first trip with this vehicle, the rear end had gone out, the clutch pack was removed and replaced, the fog lamps were holding moisture and were replaced, the brakes would pulsate and pull from one side, the shifting was harsh when changing from first to second gear, a loud clunk would be present at times when starting from stop then decelerating and the vehicle would crank but would not start at times.
