My Flex has repeatedly lost power while driving. I can feel the car lose power, and the yellow wrench light comes on. After reading up on it, I learned that you have to turn the vehicle off, wherever you are, and restart it after a few minutes. The wrench light turns off, and the car runs as normal, with no records of codes. This is talked about over and over in online forums. The safety issue is that it has happened on the freeway several times while traveling at a high rate of speed. The car loses power, and you cannot accelerate. You have to find a way to stop immediately, put the car in park (and listen to the transmission clunk) and turn it off. This last instance put me in harms way on the freeway. The car lost power while traveling 70mph. I immediately lost speed and had to cross 3 lanes of traffic to pull over to turn the car off. …

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. …
The door ajar sensor malfunctions and is crazy expensive to fix. There are numerous posts and videos online of workarounds bcz it's so common but they don't seem safe since that's a safety feature and the workarounds are simply a way to trick or bypass the warning sensors since the doors are actually closed in most cases. Ford needs to take ownership of this and issue a recall. There's a tire pressure sensor failure as well.
