When the brake is depressed the engine accelerates...never know when this is going to happen...Almost went through the garage wall...It has happened only a few times since new. But it could cause very bad things to happen....

F150 2008 V8 Lariat with 60,000 miles. Engine has been surging at normal driving speeds intermittently for months, but much worse in the past several weeks. Ford dealer said no codes showed up on their machine. At my request they replaced the fuel filter. Truck ran fine for several days, but has started same problem again. Engine fail safe code came up for first time today.

F-150 King Ranch 5.4L

  • Automatic transmission
  • 46,999 miles

On January 1, 2012 I went to my mail box at 5:00 in the morning to check my mail. I drove forward to my mail box about 300ft from my carport. I backed up to put my truck under my carport. When I was in my position to set the vehicle in park I gently touched my brake (I use one foot to drive with so I rotated my foot). I gently touched the brake at this point I saw smoke on both sides of my vehicle I thought my truck was on fire. Before I had the time to figured out what was going on one or two seconds. The vehicle took of backwards at what I assume was full speed. I went about 60ft and could not stop the truck with my brakes. I ran thru a 2ft ditch, over my outside AC condenser unit and slammed into my brick house.

My grandson came out of the house at this time I was getting out of the truck I thought it had shut off but my grandson said Papa your truck is still running. I could hear the whining of the tires so I turned the ignition switch off. I had my grandson take pictures one that really got my attention was the tire marks under the carport. There were two tire marks about 5ft in length where you could see that the truck was peeling out that was the reason for the smoke. I got the truck unstuck and drove it around and to the ford place where I bought the truck for some reason when Ford found out that this had happened to my truck they put a number on file and told the dealership that no one was allowed to work on the vehicle.

I left the truck parked there and a lawyer named Holden Hogget took the case and strung me along for over 3 years by this time my extended warranty had expired and he dropped the case without a call just sent me the case file. I picked up my truck had my homeowners insurance pay for whatever I could get for damages but I now have a pickup truck that I have a problem selling the truck now.

Any suggestions? I have the pictures of the damage and the peeling out marks but not sure how to send.

This is the second time that while touching the brake to park, the engine accelerated and had to shift to neutral to avoid hitting a car.

F-150 Lariat 5.4L

  • Automatic transmission
  • 38,000 miles

While pulling in to the curb to park touching the brake the engine accelerated and nearly hit the vehicle in front of me. Shifting to neutral caused the engine to go back to idle. Very scary situation and I was very glad I wasn't stopping for people in a crosswalk. Talked to several people about this and nobody had ever heard of such a thing. Did not pursue any remedies thinking it to be an isolated event and would be careful and aware in the future.

F-150 4.6L

  • Automatic transmission
  • 35,000 miles

The problem I'm having is the unexpected revving. I've noticed that it only does it while I'm braking. If I let up on the brake pedal and reapply the rpm's drop down to normal. It almost seems like a vacuum problem but I'm not sure where to go from there. Any suggestions?

This is my 84 year old father's truck. He has had 4 separate occasions of sudden acceleration. It has been documented 3 times by our local Ford dealership and told nothing was wrong with this vehicle. I have looked on the internet and have seen far too many of the same issue with no resolution. My father is very much in favor in starting a class action lawsuit. Who is with us?

F-150 XLT 4x4 5.4L

  • Automatic transmission
  • 38,000 miles

Ok, I just bought a 2008 Ford F-150 XLT 4x4 ext Cab w/ 5.4 3valve engine. Came up to a stop light with a slow stop, nice and calm. All of a sudden my truck revs up to around 2000RPMS on its OWN. I felt the engine pulling so I strong legged the brakes and the truck basically did a weak power brake! I get the truck home and remove the air intake system to where the throttle body was visible. I looked over the mass air flow sensor and it was fine. I checked the butterfly valve and it wasn't sticking. I checked the throttle position sensor and it was plugged in fine. Before I bought the truck, I found out that Ford didn't put a throttle cable from the pedal to the throttle body. Why? I saw the giant mainframe on the throttle body probably called a throttle solenoid or whatever but damn what was wrong with a good ole fashion wire? This crap is dangerous! If I hadn't had gave the pedal a stiff leg, accidents would have went down.

The 2008 Ford F-150 accelerated on its own and crashed into a wall. The brake were pushed the whole time (about 200 feet). Long skid marks on the ground proving the brakes were engaged and crashed into a wall.
