: 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.

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.

Since new, the vehicle has had brake issues. After about one month, the brakes constantly squealed on aplication, degenerating into a hard contact rumble causing the steering wheel to vibrate. The dealer has service the vehicle three times and replaced the brakes twice. After every repair, the issues re-appear. I was told by the service manager of downtown Lincoln Mercury to "roll up my windows and turn up the radio". There is an obvious defect in the brakes and/or the braking system on this vehicle that Ford does not know how to properly repair.

Also at 45 mph there is a front end shimmy. Only at that speed. Nothing frightening but wonder why, will it occurr again later at increased mileage. My biggest complant is the noise coming in left side from either front or rear door. Has been back to dealer four times and we live approx. 40 miles one way which is the closest dealer. I beleive something could be done if they have to take it to a wind tunnel testing station. Their attitude has been good but no corrections. Very disgusting for new car. I am ready to dispose if necessary. I have a good sound system for no avail.

Vehicle downshifted into passing gear while driving down a hill and vehicle accelerated. Brakes did not response, causing consumer to run into a bus and telephone pole. Also, dual airbags did not deploy. But, cover came off, resulting in a broken hip and pelvis. Prior to this accident consumer was complaining about transmission. But, dealer stated it was not important.

Car pulls to the left when coming to a stop. Not always. Weather doesn't matter. Not due to crown on roads or ruts. Brought in for repairs 3 times. Make repairs suggested by manufacturer but didn't help. Consider a safty factor in mulit - lane traffic. Service department can not duplicate problem because it is intermitting which makes it hard to repair. No complaints about service department.
