The contact owns a 2004 Ford F-150. The vehicle accelerates on its own while driving. In addition, the vehicle accelerates on its own when the accelerator pedal is not depressed and when stopped at a traffic light or stop sign. The failure has been occurring ever since the vehicle was purchased, but it was more of a safety hazard when the contact allowed someone else to drive the vehicle. The dealer stated that the throttle sensor needed to be replaced. The speed was unknown. The failure mileage was 48,000.

F-150 4WD 8-cyl

  • Automatic transmission
  • 32,000 miles
The 2004 F150 SC has a few problems: First was the water leaking from the third brake light in which I had to apply silicone around the rubber seal of the light...never leaked again. Second issue was far more frustrating, when traveling around 40 to 50 mph when deciding to accelerate quickly the truck would act as if it was being starved of fuel. The best way to describe it was by depressing the accelerator and releasing it very quickly. I took it to the wonderful Ford dealership, sarcastic, and they told me nothing was wrong, and shop manager told me it was because of cold air intake... finally, after calling Ford customer service and complaining the dealership decided it was my throttle body...naturally all my problems were gone. Now, less than a year later the problem arose again and I will post the outcome once known. The third incidence was the front bucket seats, started noticing shredded foam under the front part of the seats, not knowing what it could be I assumed it was excess foam around the seat straps located under each seat, to my surprise a hole appeared on the driver's seat on the front left corner facing the door and again I went to the wonderful dealership and I showed them there was a piece of metal with a sharp barb that was slowly shredding the foam and was the culprit in creating the hole and the shredded foam. Caution!!!!!! if your truck has this problem be careful!!! I was getting out of the truck and the metal barb caught my pants and tore a huge hole and gave me a pretty deep cut on the inner thigh. None the less the dealership didn't do anything about it. I finally convinced them to replace the seat with me paying for the replacement cost...but, before I could get the work done the wonderful dealership went out of business and I haven't hit-up the new owners.

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)

The vehicle accelerated when pressing on the brakes. Contacted the dealer, they did some work to it and said it was a diaphragm, and they fixed it. This worked for a while and then it started doing the same thing again. This was August 1, 2005. Noticed it made a groaning sound and shook. They replaced the transfer case, and it hasn't made the sound since then. When standing at stop it surged, gave a little jump/pulsated and touched the brakes. It happened intermittently.

2004 Ford F150 XLT 4WD supercab(brakes constantly squealing)conditions were normal even braking.I never had to slam on the brakes. 've brought my vehicle back to Ford dealership three times over a period of 4 months.corrective actions are scuffing the brake pads and deglazing the rotors.it's fine for a month and the squealing is back as well as a deposit of brake dust on the wheel.I've also had two incidents concerning the electronic accelrator(Ford calls this drive by wire as it is digitally controlled acceleration)the trouble light displayed in dash panel twice over a period of 4 months.the last incident caused the vehicle engine to violently sputter and misfire causing loss of power.the vehicle was checked with diagnostic equipment and I was told that nothing appeared wrong with the accelerator module.the brakes I can live with but the electronic accelerator is paramount for the vehicle to function.no accelerator(digital) no go.loss of power, control and you might cause an accident causing injury to you and others.
