My 2010 Ford Flex began inadvertently surging forward in acceleration without me making it do this exactly 3 months after I purchased the vehicle. The Ford dealer was unable to re-produce the problem on several occasions and said my vehicle was fine. No error messages reported in the computer. This has continued to happen sporadically since ownership. I have had another Ford dealership (as well as an independent mechanic) try and reproduce and diagnose the problem with no luck. Several weeks ago I was driving my vehicle in my residential neighborhood when all of a sudden my car surged forward with great acceleration with no warning. I had to swerve into a driveway and cut the vehicle off to get the vehicle under control. I am 82 and have a heart condition. This safety issue is critical as someone could get hurt or killed. Ford has several complaints of this happening with several models. I believe it is a Ford design flaw in the vehicles electronic throttle system. Ford corporate was put on notice of these events after the latest safety event. Please, I urge the NHTSA to issue a recall before lives are lost. I can no longer drive this vehicle as I am concerned someone is going to get hurt. It is being towed to the ravenel Ford dealership for inspection and diagnosis again. . . . .

My wife and I were preparing to pull into a parking space, outside of an applebee's restaurant. When she tapped on the gas paddle to pull into the parking space, the vehicle lunged forward extremely fast, causing the vehicle to jump the curb. Here immediate reaction was pressing the brake, but the vehicle did not stop until it crashed into the restaurant. Thankfully there were not any civilians walking in front of the vehicle. The only person that was injured is my wife. The landscape and the building was damaged; along with our vehicle. Over $7,500 dollars worth of damage to the vehicle.
