My vehicle lunged into traffic, after stopping at a traffic light. The wrench indicator light indicated a failure, but then disappeared after a couple of moments. Also, while pulling into a drive through the vehicle lunged forward almost hitting another car and I had to slam on the brakes to prevent a crash. This lunge forward, the engine revs up when this happens and I think this could be very dangerous to the driver and pedestrians (imagine this happening at a school crossing!!!).

Stopped at a store and left the car running with air conditioner on in 90 degree plus heat, put the car in gear and it lunged and died. Took 3 times to get it to restart, and the wrench light came on. Vehicle then would accelerate properly. Has no done it two times. I think it might be the electronic throttle body.

We had been driving for approx. 3 1/2 hours and pulled over to a gas station. When I went to drive it again, I put it in reverse to back out of a parking spot and it lunged. I put on my brake fast.. it scared me. It had never done that before. It made it the rest of the trip. Since then, it lunges every now and then.

Vehicle surges when idling in gear and at slow speeds when A/C is on. When in drive or reverse.

Multiple times, it seems, when we have the air conditioner on, our vehicle accelerates on its own. We have almost hit others in parking lots, intersections and on the road because of this. Sometimes, it even accelerates on its own when the brakes are applied. Our vehicle has also shut off when the air conditioner is on.

Vehicle lunges/accelerates when idling or just after shifting in to gear or reverse. It can cause a big enough surge that I've almost hit a car or object in front/behind me several times but have been lucky enough to avoid that. It occurs daily.

While idling with my foot on the brake, the car started "surging". RPM's revved up and had to stand on brake to keep car from moving. Happened a few times, sporadically, then started happening more often. Now doing the same thing in reverse. Several times, when I remove my foot from the brake to back up the car "lurches" 6 or 8 feet before I can stop it again. Yesterday, the vehicle died after doing this, the wrench light came on. Car started immediately, light went off, and drove home with no further incidents. This is now a daily occurance when driving this vehicle. Not certain what is causing this. Some reports cite transmission, some cite throttle body, and some cite the need to have the fuel system professionally "cleaned".

I was waiting in line to pick my daughter up from school today. When she got in the car I took my foot off of the brake and my car lunged forward and almost hit the car in front of me. I had to push down on the brake to stop my car from crashing into the car in front of me. When I attempted to take my foot off of the brake for a second time and to drive around the other car, my car lunged again and almost stalled.

I was pulling into my garage. I was coming to a stop and the car accelerated forward and can within inches of hitting my house. Another time I was leaving my house. I put the car in reverse and with my foot on the brake it accelerated in reverse for several feet.

While sitting at traffic lights or stop signs car has tendency to lurch forward while foot is on the brake. It also at times will make a sound as if something is hitting the engine when starting.

Bought in Aug 06. Air unit working great! had to turn up the temp, because we got to cold. In June 07 started using unit and was not blowing out cold air. Driver side blew out around 55-60 and pass. Side blew out 65-70 air, even though the temp was set on 60. This car has the dual temp controls. Had in to one dealer 6 times! they rechared twice and replace the control unit because it was different temps on each side. Did not fix the problem. Then took to another dealer in next twon, they have had the car for 2 weeks now! called and talked to Ford and a tech, still have not found the problem or fixed it. They do admit there is a problem and it should blow out around 35-40. Very frustrated! at what point do they just relpace ever part conected to the air condition? I just want my car back and fixed.
