2009 Ford Flex: won't start

Filed Dec 9, 2025 · Electrical · KS

You can be driving down the road, and all your gauges will stop working, and all the warning lights on the dash will light up. The first time this happened my wife got stuck at a gas station all the warning lights were on and the car would not start, people tried to jump it and it would not affected at all. I looked on the internet and found were someone said to beat on the passenger side floorboard, I called my wife and told her to try that, and when she did the car would start. It doesn't do it all the time, you never know when it's going to happen. We have to just stomp on the passenger floor to get everything to start working again. If I had not found this information from somebody else on the internet my wife would have been stuck about a hundred miles from home. I've taken it to the Ford house and they say they've never heard of anything like this but I know it's happened before two other people that's how I knew to stomp on the floorboard on the passenger side.

Six am, totally dark, lights on low beam, total power failure while in heavy traffic and inching forward. Engine died and all electrical components failed within 30 seconds. Battery was new in august of 2014, all connections tight. I was in lane three from the right on a six lane freeway that was totally impacted with vehicles. I tried to exit to right shoulder but could not and ended up blocking lanes two and three. No power to anything but I was able to get shift lever into park and the car started. Would not start in neutral or drive. Has not occurred since after driving approximately 650 miles.

I purchased my flex new on oct 2009 and it has shut off while driving three times since I bought it. The first time it happened I was driving through my neighborhood (with my children in the car with me) at 20mph all the warning lights came on my engine shut off, loss of power steering, loss of brakes. Luckily I was able coast to the side of the street. I waited a few minutes and it wouldn't start. I tried to start it again and it started up. The second time I was driving on the highway(with my children in the car with me) at 55mph engine shut off, loss of power steering, loss of brakes and check engine light came on, I coasted to the shoulder, waited a few minutes and it started right up. I took it to the dealership; they told me they couldn't find any issues that would cause the vehicle to turn off while driving so they didn't attempt to fix it. The third time was last week while driving through my neighborhood(with my children in the car with me) at 20 MPH, engine shut off, loss of power steering, loss of brakes and check engine light came on. I took it to the dealership again and again they told me that they couldn't duplicate the issue so they didn't attempt to fix it. My children were in the car with me all three times. I've taken to the dealership 3 times for this issue and they cant duplicate the issue so they can't find the problem so they didn't even attempt to fix it. I just dropped it off this week for the fourth time. Its very frustrating to have this issue especially since im scared to drive the vehicle with my kids in the car. I feel its a huge safety issue. Its a total inconvenience to have to keep going back to the dealership and drop off my vehicle. I have three children and need a dependable vehicle. Luckily we weren't injured but im worried that the next time it happens an injury could occur. Why hasn't ford listed this issue in their tsb!

Intermittent no start of vehicle. Towed to dealer after 5 previous incidents. Delivered to dealership in same no start behavior. Upon initial attempt a relay was replaced as the PCM (main engine computer) was not receiving power. Service advisor calls to indicate vehicle is ready and starts up after repair. At the dealership, picking up the vehicle, car starts up, however, dash lights light up, warning "check awd, check this, check that..." service engine light on as well (the wrench). Shut the car down, try to restart, will not restart. Tech is with me and observes behavior and tries as well. No start again. Tech attempts to download error codes. Mentions rfi interference. Will be doing another diagnostic. Previously, car was towed to dealership for stalling at freeway speeds (65+). Ended up being a soaked PCM (main engine computer). This took two trips (towed both times). This is now four times to repair the same non-running / no start defect. The rear brakes were also repaired due to dragging calipers as per tsb 10-7-2.
