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.

The gas pedal will be stuck accelerating, and will not stop. The mat was not even on the floor when the incidents occurred. Driving down interstate and also a back road, hit the break does not stop or disengage the vehicle; tap pedal does not disengage speeds up more and remains stuck. This is the 3rd time this has happened, and luck is the only reason an injury has not occurred.

Sept 14 2013. 1400 on us 59S I was driving in the far right lane, and a funeral precession was exiting right so we slightly decelerated and switched to the middle lane. As I accelerated to acquire the highway speed limit the gas pedal got stuck; immediately I knew there was a problem and told fiance… to call 911. I began to continuously press on the brake pedal with my entire body weight. It slowed the car to approximately 60 mph and if I tried to lift my foot from the brake pedal the car would accelerate even more. On the phone with 911 --207pm-- we were trying to stop the vehicle. I moved my car to the left lane and then to the left shoulder lane. (during this time I was continuously trying to brake and shift my car to neutral but it wouldn't budge; still braking with the brake pedal, I tried to apply the emergency brake) fiance… quickly re-dialed 911 to give our location and let them know that the car was completely out of our control and that this was an immediate emergency. The 911 operator told my fiance… that a police dispatcher would be calling her back, to which she replied we needed help immediately because we were approaching on slower traffic. Very quickly after, the left shoulder lane ended so I was forced to move the car into the farthest left lane. It soon became apparent that we would not avoid a collision, and my car hit the back of a yellow Scion tc going approximately 100mph. The airbags deployed right away, making it unclear if we hit any other cars. The final impact that stopped our car was a concrete barrier on the right side of the highway. My fiance… and I immediately exited the car and stepped away while we signaled for help. Without a doubt our lives could have been taken away from us due to this event.

The contact owns a 2008 Ford Mustang. The contact stated that after installing aftermarket floor mats, the floor mat became lodged between the accelerator pedal and the floorboard, causing the vehicle to erroneously accelerate. The contact crashed into another vehicle as a result. The floor mats were removed to prevent any additional incidents. The manufacturer was not contacted about the failure. The failure mileage was approximately 70,000...upadated 01/30/13 updated 1/1/2013 updated 1/1/2013

- first incident - September 2011 - while traveling 55mph on the highway, the car stopped responding to me pushing down the gas pedal. It was still idling, but no longer accelerating. The wrench light came on. I pulled off to the side in neutral and restarted the car. The problem has not repeated itself yet. - second incident - late September 2011 - car keeps dropping below 500rpms while sitting in traffic in neutral. Car finally dies completely. Is able to restart, but repeats this behavior sporadically - third incident - while going 25mph in a residential area, car starts to accelerate on its own. I push in the clutch, checked the mat (to make sure it wasn't stuck on the pedal), but the car continues to accelerate. Around 3500rpms, I turn the car off. It restarts without a glitch. - 11/8/2011- took the car to Ford. They said nothing like this had ever happened before, and blamed the acceleration on the mat, even though I checked it. They have no explanation for the deceleration, and say there is no wrench light in the car's history.

I rented a 2008 Ford Mustang from hertz. While turning a corner, the car accelerated on its own, and I had to brake hard to stop it. This only occurred once during the several days in which I drove the car. I have reported this to hertz.
