general problems of the 2003 Mercury Sable

My car is trying to kill me! I was driving at approximately 40 mph, when I started to brake for a stop before turning . The car slowed down, as I held my foot on the brake, but suddenly the car started to accelerate. I already had my foot on the brake, and the brake held, but I had to take the car out of gear, and shut the engine off. The engine was racing at a speed I would estimate at 80 mph. It was a frightning and dangerous experience. I checked to see if a floor mat was pressing on the gas pedal. It was not. The same incident happened on two more occassions. My mechanic has not found the problem. I no longer drive the car.

I was driving my car and while I was braking for a stop light I couldn't stop. Something was giving my car gas as I was trying to stop. Ever since then when I drive it my rpm's are high and makes a noise. I called the shop and had my idle air control valve replaced because that's what the automotive place said was wrong. Since then it's been in 3 other times and had the part replaced just in case it was a faulty part. Now the mechanics are baffled as am I. I did research and noticed this was a common complaint on these vehicles. I just took it in again today December 6,2012 and we can't figure out the problem. It's getting worse to where I can't really drive it because when I go to brake it won't stop. I can be at a complete stop and not touch the gas and my car will get up to 45mph without me even touching the gas pedal.

While driving in high speeds consumer heard a loud clanking noise coming from the front. Consumer applied the brakes, and the vehicle failed to stop completely. Vehicle was taken to the dealer for inspection. There was a gas smell inside of the vehicle, a steering vibration and the oil pan gasket was replaced.
