| Purchased a new 2005 mercury mountaineer in 7/31/2005 the first time the car accelerated when the brakes were applied and the car had to be put in neutral to stop. the dealer reported that there were no known fixes for this problem at this time. the second time while pulling into my driveway when the brakes were applied the car accelerated and crash into my garage door. this time the dealer blamed my wife and said she must have pressed the gas and brake peddles at the same time. the car sustained front end body damage and my garage door needs to be replaced. the car has been at the dealer since the accident happened and we are still waiting to find out what is ford's determination of this issue and what they will do to get us out of this car and into something else. *nm | |||
