F-150 8-cyl

  • 21,500 miles
I was accelerating up a small hill. I reached 30mph and stopped accelerating. The truck continued to accelerate slowly at around 2000rpms after I took my foot off the pedal. I shifted the truck into neutral and the rpms slowly increased as it was no longer under load. I tapped the accelerator and they surged up to 4000 where they were capped by the computer. I used my brakes to come to a stop in the middle of the street and turned the truck off. I waited a few seconds and started it back up. The tachometer showed 1000rpms and then down to 700-800rpms. I continued home. This has happened 5 other times with this vehicle. I am still troubleshooting the problem, but it is not caused by floormats and I have ruled out the cruise control being part of the issue. The last time it happened, I engaged/disengaged the cruise control while the truck was accelerating on the interstate with no change in behavior. It appears to be mechanical to the throttle body or a computer malfunction somehow. It is a difficult problem to replicate and does not happen every trip. I am going to inspect/clean the throttle body and clean the mass air intake sensor. I haven't ever had a vehicle act this way and think there is a major problem if you have to turn a vehicle off to reset it. Losing power-steering/brakes is the problem with doing this while the vehicle is under way.

  • 500 miles
I was on the highway and when I attempted to pass a vehicle, when I floored the gas pedal the truck lost all power for 3 to 5 seconds almost causing an accident. It has been that way from the day I bought it until present. When I questioned the dealer on the lose of power problem I was told nothing can be done about it because it is a normal issue with fly by wire accelerator.

F-150 8-cyl

  • 60,000 miles
Just got onthe expressway from the on ramp and had speed up faster due to on-coming traffic not slowing. I stepped on the gas pedal and accelerated. Took my foot off the gas but kept going faster. I used both feet on the brake to slow down but the engine kept accelerating. I took right foot and stomped the gas pedal and released it. That got the pedal unstuck and I returned to a safer speed. I travel the same way to work and this has happened 4 times so far. The last two of which I am sure that it was not the floor mat.

  • Automatic transmission
  • 12,000 miles
The contact owns a 2009 Ford F-150. The contact stated that while at a stop, the engine rpms increased excessively and the vehicle suddenly accelerated without warning. The vehicle was taken to a dealer where a diagnosis was recommended. The manufacturer was made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 12,000 and the current mileage was 14,600....updated 05/08/13 the consumer stated the dealer advised the failure was due to the gas and brake pedal being too close together. This caused the driver to step on both at the same time. Updated 06/10/2013

F-150 8-cyl

  • 54,000 miles
I was making a left turn and my gas pedal got stuck / accelerated and I stepped on the brakes numerous times and I couldn't stop the vehicle. Very dangerous and freaked me out. I couldn't stop the truck and accelerated to over 50 miles per hour until it finally slowed down on its own after collision. I suffered damage to my front end and my rim/ tires. I hit a pole to avoid hitting another vehicle. I hope a recall is called. I am just happy no one was seriously injured.

F-150 8-cyl

  • 43,740 miles
I was entering an on-ramp onto the interstate and accelerating at the time. As I was nearing the end of the ramp, I felt the truck was traveling faster than I had intended. I removed my foot off of the accelerator only to hear the engine revving and watched the speedometer continue to climb. I was traveling between 80-85 mph by the time I was entering the interstate approaching a tractor trailer truck. I stood with both feet, straight legged with 130 pounds on the brake while not only trying to avoid the tractor trailer in front of me, but watching another tractor trailer approaching me from behind. My speed continued to climb as the accelerator remained stuck. After approximately half a mile of me standing on the brake, I heard a loud bang as the accelerator let go and my braking took effect. I took it to the closest Ford dealership who "could not duplicate the problem, the peddle must have been stuck on the floormat". as I was not satisfied, I then took it to the dealership where I had purchased it only to be told the same thing. As the person driving the vehicle, I can assure you, it wasn't stuck on the floormat. The same thing occurred to my husband as he accelerated to pass a vehicle. However, the period of acceleration did not last as long as this last episode. Both dealerships were made well aware of both incidents.

F-150 8-cyl

  • 29,000 miles
While merging onto the interstate I accelerated to 65-70 mph. Once on the interstate I let off of the accelerator but the truck continuted acceleration up to 90mph while holding at 4000 rpms. Brakes were applied to help control the vehicle speed while I shifted to neutral and pulled into the emergncy lane. Once stopped and in park vehicle continued to hold 4000 rpms. I shut the vehicle off then restarted and the rpms jumped to 4000 immediately. I shut off again left off for 15 minutes, pressed the accelerator a few times to make sure it wasn't sticking to anything (it was not) and restarted. At this time the vehicle appeared to work normally, drove on home. Took the truck to the dealer the following Monday, left it for them on Tuesday. They said there were no codes and could not replicate the issue and therefore nothing they could do. This is the ninth problem I have had to take the truck in to have fixed under the warranty.

The contact owns a 2009 Ford F-150. While driving approximately 40 mph, the accelerator pedal dropped to the floor board abnormally. The contact placed the vehicle in neutral and shut the engine off. After restarting, the engine exhibited an extreme increase in rpms. The contact shut the engine back off and heard a popping sound from the accelerator pedal. The contact drove the vehicle to the dealer for diagnostic testing where the technician stated that the floor mat may have become stuck to the accelerator pedal. The contact believed that the failure was not related to the floor mat. The vehicle was not repaired. The approximate failure mileage was 56,000.

  • 13,250 miles
I experienced unintended acceleration while backing up. I had just started the engine and placed it in reverse and then tapped the accelerator lightly to start moving. The vehicle then started to accelerate rapidly backwards. Luckily my foot was off the accelerator for I was in a school parking lot and on a slight incline so I was riding the brake lightly. I had my right foot fully on the brake pedal and could barely keep it slowed. I placed the engine in neutral and the tach showed a steady 4000 RPM, again my foot was still off the accelerator. I then turned off the engine and restarted and all seem normal. I took it to the dealer and they could not duplicate or show any computer code errors.

  • 64,000 miles
While driving 65 mph the truck accelerated to 95. I turned off the cruise control, thinking it could be stuck, even though I was not using it at the time, braked as hard as I could and got the truck to slow down and got off the interstate to a side road and finally got it stopped. I turned it off and restarted the truck. It immediately ran up to 5K rmp. I shut it back down and called a friends who is a mechanic. He told me to disconnect the negative side of the battery and let it sit a few minutes. Did this and it restarted and I got it home. Had it towed to the Ford dealer since it is still under warranty. The Ford dealer's service department cannot duplicate the problem; states that 4 people have driven it; they let it run for two hours and all diagnostics tests indicate all is well. Evidently there is an issue somewhere. I just pray I don't kill somebody or myself next time.

  • 21,000 miles
While pulling away from a drive through window, I took my foot off the accelerator to put on the brake as I neared the stop sign at the intersection to enter main road. As this happened the truck accelerated suddenly and darted the truck and passengers into 2 lanes of traffic where they were hit by a van which in turn swung them into the opposite 2 lanes of traffic (so truck went through 4 lanes of traffic). Truck's airbags deployed on driver and passenger side (with driver seat bags too) and no injuries occurred. Truck is being fixed and will be taken to local Ford dealership afterward for evaluation.

  • 12,763 miles
Driving a 2009 Ford F-150 I was just past the grain valley exit eastbound I-70 heading back to columbia. I was in the left hand lane and pressed the accelerator to get past a car in the right hand lane. When I took my foot off the gas, the rpms went way up, as if it were floored, and the truck tried to accelerate. While there was a car in front of me, luckily there wasn't one to my right. I stood on the brakes and swerved to the right. Standing on the brakes I was able to keep the speed between 60-70 mph, I threw on the emergency lights and pulled onto the shoulder. After maybe a hundred yards and throwing on the E-brake and hitting the brakes I was able to slowly bring the speed down at which point I turned the truck off. After waiting a while on the shoulder I turned the truck back on and everything seemed normal, I put the truck into drive and began to slowly press on the accelerator to get back on the highway. It was then that the RPM's again kicked way up and the truck began to try and take off. Luckily I wasn't going very fast and rode the brakes and turned the truck off. I then called a tow truck. There were no injuries. The extent of damage to the truck is unknown as it has not been taken to the dealer yet to get fixed.
