2010 Ford Flex. Consumer writes in regards to vehicle throttle problems. The consumer stated the vehicle would accelerate on its own, which then caused the vehicle to go into safe mode. The vehicle immediately slowed down and would not go above 10 mph or it shut off completely. Ford informed the consumer, the fix would cost $550.
While driving on a highway during rush hour traffic, as the traffic slowed down, and I pressed the brake, the engine shut completely down. First the battery light came on and then all lights within the speedometer cluster came on. Traffic began to pick back up and I was going up hill, yet I was merely coasting at the the speed I was before I stopped and slowing down. Luckily the traffic did not come to a complete stop because I would have been sitting in the middle of the road. I am not exactly sure what the speed was because I was more concerned with what I should do. I was in the middle lane and not able to get over. With my wife and two toddlers in the car, I thought quickly and put the car in neutral and attempted to restart the car, it worked, and I was able to place the car in drive without even making a traffic backup. All this happen so fast. I dropped everyone off and took it to a Ford authorized dealer who so far has told me that there is nothing they can do because there are no errors in the computer and they cannot duplicate the error. They told me "I" would have to drive it more to get a better understanding of what is going on. So in order for Ford to do something about this error, (that I have found all over the web (engine shutting down) regarding the Ford Flex), more with the 2009 models; I have to get in a car accident because my car shut down in the middle of traffic. (this is my interpretation of what the dealership told me). That is the only way I can get Ford to look at the problem seriously. This is the second incident. The first time I thought it was a fluke, but I was coming to a stop the first time. The car started again so I thought it was a fluke.
