There is currently an issue with our ecoboost v6 turbo charger. There is a old drain tube leak that has been identified through ford and is a fire safety issue. This issue has been recalled for the 2014 and 2015 ford flex which is identical parts as our vehicle but never recalled. Would like to see this get recalled before harm is had. This is an ongoing leak that has gotten worse over time.

My flex ptu system had to be replaced because it fell apart while driving. There was a loud boom then severe grinding when I tried to accelerate. The mechanic said this problem happens so often with ford awd systems that they keep them in stock. I contacted ford directly to complain and find what they were doing about it. I was advised there was nothing they could do and that I should file a complaint with you. The cost to repair my vehicle will be $1500. That is not a minor fix and I believe ford should be doing something about this.

On approximately august 15, 2013 we were driving our son to school when chimes came on stating that our doors were open. We stopped, checked all doors. None were ajar. We continued on driving at which time our son opened the door. Had he not been in a car seat he probably would have fallen out. We were in a residential neighborhood and were only going about 15- 20 MPH. Our chimes continued to go off and still to this day we are having the same problem. We have taken it into the dealership many times and explained the problem. The dealership did tell us that they are aware that there are problems with the sensors but that there haven't been any recalls. They did change one of the sensors for the front passenger door at our own expense, however it has not fixed the problem because it is going off still and now the driver front one is starting as well as a "shift to park" sensor. The doors will not lock and the lights will not turn off inside the car. As far as the transmission problem goes. It will slip into neutral as you are driving. It has happened may times and it is going to cause a serious car accident. You have to stop the car, turn the engine off and restart it in order for it to go back into drive. We have brought this to the dealerships attention however every time we take it into there they say they cant see or find a problem with it. It is very frustrating because we make a car payment every month on a vehicle we don't drive. We have a 2009 flex that we have never had any problems with which is why we purchased a newer one with a lot less miles! Unfortunately we owe more than the car is worth on our 2013 flex otherwise we would have gotten rid of it by now. We hope you will really look into these problems before someone ends up really hurt! We notice there was a recall with similar problems but ours was not included in that supposedly.
