I have a 2005 F-150 supercrew. Over the last several months - approximately 70K miles on truck at the time - the vehicle goes into a "fail safe" mode with the codes P2111 and P2104. The accelerator stops working and you have to coast to the side of the road and turn the car off. The orange wrench light comes on. This has happened about 15 times over the last 3 months. It has been very unsafe and concerning, especially when it happens on the highway. I was told it was the throttle body and that there have been numerous complaints. It seems to happen intermittently and without warning. I have taken it to the dealer and contacted Ford who states there is no current issues with this. I am very concerned about the safety of my family and the vehicle and have found numerous complaints on online Ford forums. When I went to order the part, I was advised by my dealer that it was on backorder. That causes me even more concern!! I know I am not the only one who is having this problem and it seems to be a serious safety problem.

  • 63,000 miles
The following incident has been filed with the Ford Motor Company. I want to be clear that this incident was not the result of a floor mat or driver error. At no time did the driver have her foot on the accelerator nor was there an object on, around, under, or over the accelerator. Incident: On 18 February 2010 at approximately 1230 pm my wife, mother in-law, father in-law and infant daughter were proceeding northbound on water tower rd. Located in bentonville, ar. There were zero distractions inside the vehicle and my wife was fully alert with no physical impairments. Road conditions were dry and weather was sunny with great visibility. As they approached the intersection of water tower rd. And battlefield blvd. At approximately 5-10 miles per hour, my wife began breaking. After placing her right foot on the brake pedal, she immediately noticed/heard/felt/experienced increased acceleration and decreased breaking power during her attempts to stop. She immediately increased pressure on the brake pedal ensuring her right foot was not on the accelerator. The engine continued its efforts to increase speed while my wife fought to bring the vehicle to a stop. They proceeded into and through the vacant intersection at approximately 5-10 miles per hour and fortunately without incident. My wife's efforts to stop the vehicle continued beyond the intersection for an approximate 150 - 200 feet. The vehicle finally ceased its efforts to accelerate and came to rest at that point. After regaining their composure, my wife pumped the brakes in effort to determine the malfunction. Unable to determine the problem and feeling comfortable to drive again, they proceeded cautiously only to have this happen once more. This second occurrence happened less than mile from the previous location with my wife being prepared for the malfunction. During this occurrence she pumped the brakes and stopped the increased revolutions of the engine immediately.

2005 Ford F150 vehicle loses power and all control while driving on the road. This happened at least six times. Very lucky traffic was light most times but one almost a caused rear end collision. I replaced a throttle sensor and the problem disappeared and the problem returned after a couple of weeks. I took it to the dealer and they replaced electronic throttle body and throttle body and motor assembly. They also performed PCM reflash power train control module and retest. The codes received with scan tool were P0121, P2104 and P2112.

Occasionally the cruise control will not release either by pressing brake or turning off on steering wheel button. Have to brake against cruise control until vehicle slows enough for it to drop out. Which is nearly stopped.

My 2005 Ford F-150 stalled while driving at 30 mph. Accelerator had no response and truck went to idle RPM. Had to coast to the side of the road on a busy street. I consider this very dangerous especially if it happened under different circumstances such as entering an intersection. The dealership fixed it and said it was a problem with the electronic throttle system.

  • 75,000 miles
My wife was driving to work when the vehicle loss power at the accelerator pedal, the truck was running but when she tried to depress the accelerator pedal nothing, she said on the dash it said that the vehicle was running in a fail safe mode. She safely made it to a area where she pulled the operators manual out and begin reading. The only fail safe mode she found was about the cooling, the temperature was fine, she called me I told her to turn the vehicle off then restart it she did and it ran fine. I had the vehicle in for a recall for the breaks I ask the dealer to run a diagnostics on it to see about what had happened, also it a had repeated the problem a couple days in a row but only did it in the morning after 20 minutes of driving. The dealer could not find anything wrong with the truck, no codes were showing any issue. The tech said he ran through the system but found nothing he said he reset the computer if it did it again to bring it to the dealer. It did it a couple more times I took it to my mechanic he said it wasn't showing any codes either. I contacted Ford consumer with the issue telling them I just wanted it fixed they said the dealer could not find any code faults and could not repeat it so they Ford could not fix it. My mechanic said that he had the same issue with another 2005 Ford 150 truck he said it was a problem with the electronic accelerator. I'm afraid it's going to do it again and my wife won't be able to prevent getting rear-ended. Also Ford consumer said they didn't show any issues with the accelerator on this vehicle, I know this isn't true by what I've read here on this web site. Please help...

F-150 4WD 8-cyl

  • Automatic transmission

We own a 2005 Ford F150 supercrew pickup bought in June 2005. Over the past 3 years we have had numerous instances where the truck will accelerate unexpectedly when either just coming to a stop or when completely stopped. Example- sitting at bank drive through- stopped- when the gas was hit to move forward, the engine revved up and it took both feet on the brake to stop the vehicle- with wheels spinning. We believe it to have something to do with cruise control. Have had to dealer on 2 occasions they find nothing. Last week, I drove the vehicle and was coming to a stop behind a truck at a red light. As I braked, the engine revved to high, wheels were screeching, I kept both feet on brake- the engine would not slow down. I threw it into park- still had engine revving and turned off key before it stopped. We had our personal mechanic look at it. He can find nothing wrong. I refuse to drive it anymore and want it on record that there is something wrong with this vehicle that could kill someone some day. Any feedback is appreciated. 3/11/2010 update invoice received.
