While slowing for a red light, pressed brake pedal and vehicle immediately accelerated becoming uncontrollable. Collided with a pick up ahead ,which was pushed into a small compact ahead of it. Airbags did not deploy. Had experienced slight acceleration on a previous occasion, which was discussed with my mechanic. ( had also had this problem on my 1999 ranger which was resolved by replacing iac motor.) vehicle currently in dealers shop, where service personnel are unable to replicate occurrence nor find source of problem. Ford motor company disclaims any knowledge of problem although many several similar events involving this model year are well documented. Vehicle is well within warranty parameters but little, if any, action is ongoing. I am reluctant to resume operation of this vehicle while condition persists.

Dt*: the contact stated while applying brake pressure at low speeds, a squeaking noise was present. The vehicle was inspected by a dealer who determined the squeaking noise was normal, and that was the way the brakes were designed. The manufacturer was not alerted. Updated 01/10/07.
Dt*: the contact stated while backing out of a parking space at 5 MPH, the brake pedal was depressed and the vehicle surged in reverse. The contact shifted into neutral, the engine revved, and the tachometer rose quickly. The vehicle was taken to a service dealer, where the dealer was unable to duplicate or determine the problem. The dealer told the consumer, the incident was due to driver error and when she applied the brake she inadvertently pressed the accelerator as well. Updated 09/11/06.
Dt*: the contact stated the vehicle has been to the dealership numerous times because the brakes are defective. When pressure is applied to the brake pedal, the pedal intermittently goes to the floor. Most often this occurs while starting the vehicle and placing it in gear. On one occasion a power booster was replaced on the brake system. This did not correct the problem. On another occasion, there was a pedal pressure test performed. The dealership determined the pressure was a little low, but not enough for concern.
Dt: when applying brake pedal pressure the pedal goes past the accelerator to the floor, most often this occurs when starting the vehicle and placing it in gear. When this occurs it is easy to hit the gas pedal as well when trying to apply brake pressure. This causes the tires to squeal and the car to lunge forward. Has been to a dealer who said he would have a service manager call the consumer about this problem, but he never returned the call. The service representative noted there was nothing wrong. No repairs or changes have been made.
