The contact owns a 2008 Ford Mustang. The contact stated that while the son was driving approximately 40 MPH and pressing the brake pedal to reduce speed, the engine began to rev and the vehicle continued to accelerate. The driver observed that the accelerator pedal had remained pressed toward the floorboard and reached down to manually lift the pedal to reduce the vehicle's speed. The vehicle then drove into an intersection and crashed into a second vehicle. During the crash, no injuries were reported. A police report was taken at the scene, and the vehicle was towed away. The cause of the failure was not determined. The manufacturer was notified of the failure and referred the contact to the federal safety agency Hotline. The local dealer was not contacted.

My daughter and I were getting home from a short trip. As I was slowing down and turning into my driveway the car accelerated out of control. I had to turn sharply to avoid a parked car and was headed straight into our neighbors house. I stomped on the brake, but it just went to the floor. I was about to throw the car into park when I regained control. Stopped the car, put it in park and told my terrified daughter to get out and go in the house. I backed up, pulled into my driveway and parked it. I'm scared to drive it now.

I was driving home one evening when stopped at a traffic signal,my mustang throttle for unknown reasons the accelerator was stuck on the floor and remained wide open for approxaimately 1.5 miiles before I wa able to stop my vehiclesa, without injuries or death to myself and the public. This happened again with this vehicle tonite with my son driving . He stated the throttle/accelerator had stuck wide openwith the accelerator on the floor. As he was unable to shut the vehicle off . This seems to be a large issue wityh ford vehicles only to find no recalls but with one make the escape. The vehicle is a danger to public safety abroad for you never know when thids will happen. I was in rush hour traffic and am grateful by blowing the horn and the ability to think quick no one was killedb. My vehicle is being taken to the ford dealer in the am to coorect an issue ford motor company needs too address . After researching complaints thereare numerous complaints with no results.

I was driving on the interstate highway when the gas pedal stuck and the car continued to accelerate. I tried to stomp on the brake several times but was unsuccessful. Tried to turn the key, but couldn't get it to turn. Finally stomped repeatedly on the gas pedal until it released and stopped accelerating. There was nothing under the pedal causing it to hang. The floor mat was not in the way. I was in heavy traffic and only by the grace of god narrowly missed having an accident. Have not driven the car since I got it home.

When driving down the highway during afternoon rush hour, my car began to accelerate at high rate (stuck at 4000-5000 RPM) causing me to speed down the highway with very little ability to stop as I hit the brakes but could not overcome the acceleration. Thinking as quickly as I could, I threw it into neutral to bring the car to a crawl and slowly roll to the next exit and then to a stop. I was lucky to think so quickly because otherwise I could have run into the cars in front of me as the car sped down the highway with no ability to stop. I fear for others that may have this problem because if there was a stop ahead, it could easily end in loss of life. Once safely on the side of the road, I attempted to restart the car, only to have it rocco tongue to rev. After taking it to a ford dealership, I was told that my throttle electronics had malfunctioned causing the throttle to get stuck open. This is an extremely dangerous problem. Ford's handling of it, which was to say that they couldn't do anything about it is unacceptable.

At high and low speeds (different occassions) the check engine light would go on and the vehicle would no longer respond to the accelerator. It would go into "limp mode" and only proceed at idle speeds. Happened sporatically at several times including dangerously at highway speeds.

I was getting on to the highway in a mustang I had literally just purchased, I pushed the pedal to the floor and it got stuck! Took numerous brake and gas shoves to finally get it to come out, if I had not been on the highway there would have been an accident.

This is about the 20th time this has happened, went to pass a slower car and the accelerator pedal stuck and went to the floor, this has been happening at least once a week, this is a fly by wire system the issues in the pedal assembly, not the computer or anything else, no one can find a problem, but a few have said this is not the first they have heard of it, I have taken the pedal out tried to lube it and any thing else that comes to mind to free it, there is never a warning when it will happen, makes no difference if you push hard or soft. I have owned car since 9-10-14 and has happened about 20 times no help from dealer as was purchased as is no warranty, I have talked to a ford dealer they say nothing they can do, when this happens I have to shut off the engine pull to the side of the road and play with it till it frees up and returns.

I was merging onto the I-5 freeway near a big mall with fairly heavy traffic and I "floored" it, or close to flooring it, to get up to speed to merge. I got onto I-5 and let up on the gas at about 60 MPH to go with the flow, but I could hear the engine growling and the car just kept going faster. The accelerator was stuck! I stepped hard on the brake but it barely slowed the car. I then tried tapping the accelerator but the little movement just made the car go faster and did not unstick the accelerator. I was really close to a major collision, I could not go into any other lane and I was very quickly approaching the vehicle in front of me. I was just trying to figure out if I should pull the hand break or turn the car off when I thought to use my left foot to pull back on the aftermarket floor mat. I did this with my foot still on the brake and shortly thereafter the issue resolved just before hitting anyone. I was 85% sure it was the floor mat, but then when I googled the issue, I see pretty much the exact same story and in those incidents it was not the floor mat. I took the mat out at as soon as I could. When I got home I tried to see if I actually could move the aftermarket rubber mat and it did not really move. So now I am 85% sure it was the car and not the mat. Not being 100% sure of what caused the problem has me very nervous.
