My wife was driving our 2009 Ford flex in a driving rainstorm approximately 500 miles from home and the car died twice. Each time, she called roadside assistance and a tow truck had to come out and pick her up. A local Ford dealer look at the car, but naturally did not find anything wrong. She made it back home and I took it to the dealer we purchased it from (crain Ford + little rock, arkansas). They kept it for a week and we drove a rental car around. They never did find out what was wrong. Now, today, december 11, 2009, my car is back in the shop for the 2nd time for brake grinding. They tell me also that I have to pay for a new tie rod...$500. I'm sick of Ford motors!! *tr

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

The vehicle over heats, and just gets too hot. If the a/c is running it over heats just sitting at the light. Now that it is cooler, the heater is on and it over heats just sitting at the light. I stop the car and let it cool down but it should not be operating like this. There are many problems describing this same problem and it is a factory defect and needs to be corrected. No reason just sitting at a stop light for the car to over heat.

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 fuel gauge will read between 1/2 and 1/4 tank then immediately make a *ding* and the display reads 0 miles. The fuel gauge will drop to empty. If you drive anything further than a short distance (10 miles or so) the car will die. It is "out" of fuel. Refilling the tank you will find that the vehicle still has whatever fuel the gauge was showing before it dropped to zero. It is consistent, it does this every tank. Appears to be getting worse as time goes on.

12/09/2015 113,000 mi ODI #10809321.0

Traveling at 70mph the fuel gauge indicated slightly over 1/4 of a tank left and the estimated miles to empty with the mileage-to-empty estimate indicating approximately 70 miles left. Then in under two minutes to when I checked the dash again, the gauge had dropped to zero with the estimator showing 0 as well. Within the next mile the engine ran out of fuel. To fill up the 18.6 gallon fuel tank it only took approximately 14 gallons at the pump. This indicates that approximately 4.6 gallons of fuel were still remaining in the tank. Since this model uses a fuel tank design with two sumps the fuel isn't transferring from the one side to the other where the fuel pump is located. This can cause dangerous driving conditions for someone expecting to have one quarter of their fuel tank left.

The paint on the roof starting peeling. I called the dealership since I still had a warranty and they told me it didnt cover paint. It started with a small spot but it continued to flake and is not about the size of a softball. There are now 3 spots like this on the roof. This is the 2tone paint with a silver roof. *tr
