My Ford Flex stalls while driving anywhere from 10 mph (in residential area) to 80 mph on highway. Electrical is still working the engine shuts off and I lose control of gas/brakes. Three warning signs pop up at the same time: check brake system, collision warning not available, and service advance trac. Once I restart the car, the codes will disappear. The problem was intermittent at first, but now it's occurring more frequently. I'm too scared to drive my car now. Ford isnt being much help. I need help.
The first incident occurred April/2014 while my Flex was idling in the driveway and shut off and would not start for about six hours. I did nothing to diagnose or troubleshoot, it just started after sitting for that time frame. It did not go to the shop. The second incident occurred June 11, 2014 while I was driving about 5 minutes from my home. The engine shut off while I was traveling about 30 mph, I coasted to a halt in a traffic lane and it would not start. It would crank, but not turn over just like the first incident. It was towed to a shop where it was determined the fuel pump was not getting power, but before it could be isolated the vehicle started. The tech advised since it started they would not be able to do anything further. I took the vehicle to the battlefield Ford dealer and told them the issue. It was due for a recall which would switch out the fuel pump and fuel pump control module and was advised that should fix the problem. The service was performed. On June 26, 2014 my wife got in the vehicle in the morning after it had sat in the driveway all night, and when she hit the start button it took many more cranks than usual for the vehicle to start. As soon as she turned from the driveway it started sputtering and fluttering and the engine shut off down the block from our home. She coasted to a halt, the vehicle did start again and she parked it in our driveway. It would crank and crank but would turn over. I called the dealer and had it towed there, fortunately I have aaa. My vehicle is out of warranty to due to mileage. As it stands now this is a very serious issue. We live in northern va and travel I-95 frequently and if the vehicle would turn off while traveling there it could be tragic. We don't feel safe driving this car anymore and will more than likely trade it once the dealer fiddles with it.
