After coming to a complete stop, I accelerated rapidly and let off the gas pedal once I reached the posted speed limit...the truck continued to accelerate on its own !! I had to stomp on the brakes to slow the truck down, threw it in neutral and rolled to a scary stop. The truck continued to rev to 4000 RPM's while in neutral. My wife jumped out of truck while we were at a red light. Luckily no one was in front of truck. While truck was revving in neutral on its own, I tried stomping on gas pedal several times to try to stop it from revving to no avail. I finally turned the truck off and restarted it a few minutes later, the truck idled normal. I immediately began to try to duplicate the problem to no avail the floor mat did not interfere with the pedal. I do have a video of the incident on my phone.
2009 Ford F-150 acceleration complaints
Page 2 of 3: complaints 11 to 40 of 54, newest first, as owners wrote them.
Accelerator pedal sticks, there is no rhyme or reason for this problem. This has happened on a few different occasions at different driving speeds. Last time this happened my two children were in the truck as the truck accelerated toward stopped traffic. Thankfully the accelerator let loose before we crashed into other vehicles.
Tl* the contact owns a 2009 ford f-150. While driving 65 MPH, the vehicle continued to accelerate when the accelerator pedal was not depressed. The brake pedal was depressed, but the vehicle resumed acceleration. The contact was able to pull over to the side of the road with the brake pedal depressed and turned off the vehicle. The vehicle was taken to a dealer where it was diagnosed, but the cause of the failure was not found. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 73,000. Updated 05/06/16*lj updated 05/29/18*jb
Vehicle was motion. Merging onto interstate 93. Depressed the accelerator to bring the vehicle to highway speed. When I took my foot off the accelerator, the pedal did not come back, but rather was stuck wide open. I was forced to pull into the breakdown lane, turn off the engine, put it in neutral and coast to a stop. After about 5 minutes, I restarted the truck and it was fine. This vehicle has the 4.6l 3-valve per cylinder v-8 engine with an automatic transmission. It does not have cruise control or any power options. I decided to file a complaint about this after reading over 100 reports of this same issue on the internet. The manufacturer denies there is a problem. Something needs to be done to correct this issue before someone gets killed because of it.
Traveling at 65 MPH on the express way, I took my foot off the accelerator and the truck took off, accelerating as if it was being floored!. I hit the brake pedal but the engine still continued to rev itself and accelerate. I thought it might be a stuck floor mat but nothing was in the way. I hit the brake pedal again and popped the gear shifter into neutral. This stopped the engine from revving itself and accelerating. I took the vehicle into the dealership, and they claim to have never heard of anything like this and can't find anything wrong with the vehicle! Thank god I did not smash into the vehicle that was in front of me.
After accelerating to pass on the highway (65 MPH to 70 MPH), the truck remained going 70 MPH when accelerator released. Vehicle could be slowed with difficulty by applying brakes, but would resume speed when brakes released. Fortunately, traffic was light. Cruise control was not being used at time of incident. Attempted to resolve issue for approximately 4 miles/minutes at highway speeds (determined accelerator not stuck on floor mat, engaged and disengaged cruise control, braked repeatedly while making sure I was also not hitting the accelerator). Eventually slowed vehicle to approximately 10 MPH with extreme braking on an uphill incline, at which point vehicle would not slow any further. Took truck out of gear and shut off engine (vehicle stopped). Had towed to service department of ford dealer who "could not reproduce problem" but replaced electric throttle body assembly and cleared/reprogrammed computer. When asked if incidents such as these are reported to ford for their database, the service representative said no, that they had no means to do so.
Tl* the contact owns a 2009 ford f-150. The contact stated that the accelerator pedal became stuck and the rmps increased. The failure occurred on several occasions. The contact stated that the failure was becoming progressively worse. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 90,000.
Tl* the contact owns a 2009 ford f-150. The contact stated that the accelerator pedal was stuck intermittently while traveling approximately 70 MPH on a major highway with the cruise control engaged. The contact disengaged the cruise control and the failure occurred intermittently. The contact had to drive onto the emergency lane, shift into neutral gear and applied force to the brake pedal; however, the vehicle surged forward while the brake pedal was applied. The contact had to turn the vehicle off and restart it in order to reset the computer. The vehicle was taken to an authorized dealer several times and they were unable to replicate or diagnose the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 14,676.
Approaching an yellow light at approximately 35 MPH I hit the gas pedal hard for passing gear. The accelerator stuck, the engine roaring, I had to step as hard as possible to stop the truck so I would not hit the vehicle in front of me. Engine would not stop accelerating forcing me to turn off the truck. Shocked, I sat in traffic for a moment before I restarted the engine, but it immediately went to full speed again, forcing me to again turn off the engine. My friend climbed out and pushed me out of traffic. After sitting in a parking lot for about 5 minutes I again started the engine and it started normally.
Accelerating on interstate on ramp to merge into traffic. Accelerator stuck and vehicle speed increased. Had to heavily apply brakes to stop, put in neutral, engine continued to rev, shut truck off. About a minute after stopping, a loud pop was heard in cab (accelerator unsticking??). Turned truck on, normal acceleration followed. This was the first and only occurrence.
While driving 60 MPH, I left off the accelerator to slow down to 45 MPH the posted speed limit ahead. At 45 MPH, I slightly touched the accelerator to maintain the 45 MPH speed limit, the RPM's went over 4000 and would not stop. I applied the brake, but the engine kept the RPM's between 4000 and 4200. I stomped on the brake with both feet and the un-intended acceleration stayed at the higher RPM. I could hear the anti-lock brakes engage to help slow the truck down, but the engine labored over 4000 RPM. I was concerned with not being able to stop the truck, so I shifted the transmission into neutral and coasted to the berm of the road with the engine staying at a very high RPM. Once I came to a complete stop, I shifted the truck into park and the RPM's were over 6000. I immediately shut off the engine and waited a few seconds before trying to re-start the truck. I checked the condition of the floor mat asap to verify it was not on top of the accelerator. This happened to my wife less than a year ago and nothing was found at the ford dealership and the ogc reviews suggested that the floor mat may have caused the first un-intended acceleration. As I turned the key, the engine would not start and it made a clicking noise. I got out of the truck and opened the hood to check the motor. I could not see anything, so I went back into the cab and started the truck. It started, but would not idle, the RPM's went to over 6000 and stayed constant. I shut the truck off again and waited a few seconds and on the third attempt, I shut the truck back off, because the RPM's would not idle and went to 6000 and stayed there. I adjusted the power adjustable foot pedals and waited a few seconds and the truck started and idled at normal RPM's. I left the truck at the dealership on 7/31/13 for an inspection....updated 09-26-13
Tl* the contact owns a 2009 ford f-150. The contact stated that while driving approximately 35 MPH, the engine rpms increased excessively as the vehicle suddenly accelerated without warning. The contact mentioned that the failure recurred intermittently. The vehicle was taken to a dealer where the failure was unable to be replicated. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 52,000 and the current mileage was 63,000. The VIN was unavailable.
From a stop, I rapidly accelerated to 40 MPH. While attempting to stop at red light I had to apply excessive brake force to stop. The engine was running at high RPM with foot off accelerator. I had to turn off ignition to prevent going into intersection. Then a few minutes later I was on highway going 70 MPH and set cruise. I took my exit, pressed on brake to turn off cruise. The exit speed was 45 MPH. I was not slowing down and pressed brakes very hard to reduce speed. The engine was still racing high speed as I was approaching a stop light. I had to place trans. In neutral and switch off ignition. After starting engine again RPM idle was normal and problem did not re-occur all the way home. On 7/25/13 I turned in truck to homer skelton ford in olive branch, ms. With a detailed description of the event to service personnel to inspect or repair vehicle. (this was a first event since oct. 2012) I found a code c1963 in computer using car md and loaded defect onto web site for my records.
Traveling at 65 MPH with cruise control engaged as another vehicle merged on to the freeway I floored the accelerator to avoid a collision,the accelerator stuck at a very high rate of speed (85 to 90mph),tapping the brakes had no effect,disengaging the cruise had no effect,turned the ignition off in neutral for aprox 4 seconds had no effect,cruise finally disengaged after shutting the vehicle off in neutral for aprox 10 seconds.
I was pulling my boat, when coming to a stop, to park the truck, it suddenly accelerated. I had to turn off the key to stop it. I restarted the vehicle and drove around to block and come back to make another stop and it happened again. I again turned off the key. I let the truck set for about an hour and restarted it with no other incidents. I am very afraid it will happen again. Took it back to the ford dealer when I got home and they say they cannot find any problem.
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.
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.
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.
Tl* 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. *tr...updated 05/08/13 *bf 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
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.
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.
Tl* the contact owns a 2009 ford f-150. While parked, the contact placed his foot on the accelerator pedal and shifted into reverse. The vehicle suddenly surged and accelerated on its own. The contact placed the vehicle in neutral in order to come to a stop. The failure occurred intermittently and also occurred while in drive with his foot on the brake pedal. The vehicle was taken to the dealer for a diagnostic test. The technicians were unable to diagnose the failure. The vehicle was not repaired. The approximate failure mileage was 500. ...updated 09/12/12 *bf updated 09/18/12
Tl* the contact owns a 2009 ford f150. While driving approximately 50 MPH, the vehicle began to increase acceleration abnormally. After applying the brakes, there was a sudden reduction in the speed rate and the vehicle resumed as normal. The failure recurred on six different occasions. The vehicle had not been diagnosed or repaired. The manufacturer was notified of the problem. The approximate failure mileage was unavailable.
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.
Tl* the contact owns a 2009 ford f-150. The contact stated that the floor mat was defective. The accelerator pedal stuck to the floor mat while driving at 45 MPH. As a result, the vehicle accelerated out of control. The contact was able to avoid a crash and maneuvered the vehicle to the shoulder. The vehicle was not taken to the dealer and the floor mat was not replaced. The failure and current mileages were 48,000.
Tl* 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.
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.
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.
Tl* the contact owns a 2009 ford f-150. While stopped with the brakes depressed, the vehicle abnormally accelerated resulting in a crash. A police report was not filed and there were no injuries. The contact also stated that when reversing, the rear view camera would not alert him that he was reversing into another vehicle. The vehicle was taken to an authorized dealer but not repaired for the failure. The failure mileage was 25,000 and the current mileage was 37,000.
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.
