Tl* the contact owns a 2005 mercury mountaineer. While leaving a drive-thru, the vehicle accelerated independently and crashed into an oncoming vehicle. The air bags did not deploy. A police report was filed. The passenger in the contact's vehicle sustained injuries to the back, neck, and spine which required medical attention. The vehicle was destroyed and towed to a collision center. The failure mileage was unavailable.
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.
