F-150 4WD 8-cyl

  • Automatic transmission
  • 12,781 miles


While operating vehicle in cold conditions or on cold starts the engine races. Also during this time as you try and apply the brakes the motor races and if in gear it will surge/leap forward. This cause the vehicle to crash into a block wall and damage the front end of the truck.

F-150 4WD 8-cyl

  • Automatic transmission
  • 19,400 miles
The first time this happened at 3000 miles, the second time, it was around 19,300 miles and was a bit more intense. I was sitting at the stop light, with foot on brake, the truck started accelerating to the point, I started going into traffic. I then put it in neutral and tapped on the gas pedal to get it to idle down. Luckily I was able to avoid what could have been deadly. I then took it straight to the dealer, where I was told they could not duplicate the problem, and was told I probably had one foot on the brake and the other on the gas, when I told him I drive with one foot, he said my foot could have slipped from the brake to the gas pedal. Every time he came up with a lame excuse as to what could have happened I let him know he was wrong. Nothing was done and was told if it happens again bring it back in and they will look at it. Needless to say I will be taking it to someone else next time or getting a hold of Ford to find a solution.

F-150 4WD 8-cyl

  • Automatic transmission
  • 20,000 miles
I was going to meet my husband on the side of the highway to pick up my son. I started slowing down from highway speed of 90kms/hr quite a ways back. I slowed the truck to about 30kms/hr about 40 feet behind his pickup. All of a sudden the truck I was driving gave a couple of lurches, sped up and slammed into the back of my husbands truck. I did not remove my foot from the brake the whole time. There was nothing I could do to stop the truck. On the ground beside the truck there was evidence of something strange going on with the passenger side rear tire. Like it had revved up, braked, revved and braked again. The salesman that sold us the truck came out to the scene and said that he believed something went terribly wrong and spoke to the service manager at lacombe Ford. They were unable to duplicate the problem and could not come up with a cause for the brakes to malfunction like they did. Ford Canada did no further testing on the truck. There was $8000 damage to the front end of the F150 and $1000 damage to the other pickup which we have to pay for. We had the damage on the front end repaired and decided to trade it in for something that might not kill me and my family. The day I was taking it in to be traded it failed again, this time at the stop sign at an overpass. Luckily no one was coming that day. Nothing was ever corrected on the truck.

F-150 4WD 8-cyl

  • Automatic transmission
  • 4,100 miles
The incident date is the most recent. Truck has only 4200 miles on it. On all four occasions I was braking when it began to accelerated three times at highway speeds, one time on a gravel road. The cruise was not on. I did not have my foot on both the brake and accelerator. The brakes nor the emergency brake would hold it. Acceleration went up to 3000+ rpms and was witnessed by the passenger. I had to shift to neutral to get it stopped. All four times the dealer could not identify the problem nor make it happen again. It is a very unsafe and could have caused a fatality accident. Ford did reprogram the PCM module, but it happened again after that.

Engine accelerated to high speed when braking for red signal. Was forced to put automatic transmission in neutral and tap accelerator to reduce engine speed to idle. The tachometer read approximately 4000 RPM when put in neutral initially. Brakes stopped the truck with difficulty prior to putting gear in neutral. No known tsbs and dealer not sure how to duplicate.

There was a problem with the vehicle surging forward. On September 25, 2005 the vehicle surged forward, causing the vehicle to run a stop sign. There was no accident. On October 3, 2005 it surged forward again. The engine was on and it was in park. Then, the consumer put vehicle into reverse and immediately it surged backwards. Because of the consumer's foot was O the brake it kept the vehicle from going into the street. The consumer concerned because it could have caused him to have two major accidents. When he took vehicle to the dealership, they could not find the cause of the problem.

F-150 8-cyl

  • Automatic transmission
  • 108 miles
Runaway throttle/un-commanded acceleration event. Brand new vehicle, only 110 miles on odometer. While waiting for a stoplight with right foot on brake and transmission in drive, engine began accelerating unexpectedly. Neither I nor anything else in the vehicle was pressing on the accelerator in any way. The un-commanded acceleration increased. I pressed harder on the brakes and the acceleration continued to increase, to the point that the rear wheels broke loose and started to squeal (this is a rwd vehicle). Then I moved the transmission selector to neutral, at which time the torque to the rear wheels was removed. The engine raced to about 3000-3500 RPM as observed on the tach and then returned to normal idle. At this point everything was normal, so I continued to drive to work since I was very close. No further problems were noted. I parked the vehicle in our parking lot and called the dealer (berge Ford, mesa, AZ) for further advice. All of this happened within about a three second period. The vehicle had been started from cold at about 6:30 am after being parked in garage overnight (on board thermometer read 89 F when I started out). Runaway throttle event occurred after driving about five miles. Air conditioning was on the entire time.

2005 Ford F150. When reversing then going forward the vehicle surges forward. It feels like the cruise control kicks in and it is hard to stop. Took the vehicle to the dealership at least 7 times. He talked to a different manager each time. The consumer almost went off of a cliff. This happened the first time the day of purchase. He took the vehicle back the following Monday and the dealership reprogrammed the chip in the accelerator. The problem recurred. The dealership stated they could not duplicate the problem. He has called Ford, and after they contacted the engineers, he was told there was nothing they could do. He would have to take it back to the dealership. It has happened at 7 times.

The consumer stated 2005 Ford F150 surged forward. It felt like cruise control kicked in. He took the vehicle to dealer, and dealership called Ford, and they had the accelerator chip realigned. After the vehicle was fixed the surging continued. He continued to contact the dealership and Ford. According to customer service the engineers said they could not find anything wrong with it. Consumer was currently afraid to drive the vehicle, so was sitting in the driveway. The vehicle was taken in last week, and they kept it for a week, and they stated they could not find anything wrong with it. On the way home transmission slipped and surged forward. Dealership and the manufacturer kept telling him to call the other. Consumer stated vehicle has been at dealership at least five times, and got a different service manager every time. The problem started the night he purchased the vehicle.
