My 2011 Ford Flex 3. 5l engine has had cadastrofic failed due to premature failure of the internal chain driven waterpump. The o-rings on the waterpump failed there by allowing oil into the coolant and causing the prepellers on the waterpump to break off and block the water passages in the engine with the oil and propeller parts. Also, allowing coolant into the oil. Through my research, I have come across many Flex owners as well as othe Ford owner that have the same 3. 5l engine withe the internal chain driven waterpump have had the same or gerry simular issues and many have had to spend thousands for a new engine. Ford needs to recall this design flawed engine and waterpump.
Tamara recall.
Timing chain rattle upon startup is getting worse. Same issue with f150 ecoboost motors was covered under recall but nothing for Ford Flex. The timing chain breaking can cause an engine lockup and create a dangerous accident.
Shuttered at highway speed. Both turbochargers on the ecoboost engine are destroyed at 62,000 miles. Metal shavings in the oil filter clogged oil lines. Most likely engine destroyed.
The contact owns a 2011 Ford Flex. The contact stated that while driving approximately 40 mph, there was sudden reduction of engine power without warning.

It has happened since 2012 sept, when I bought it at 4000km. I was about to start from a traffic light. I let go my brake and 'slightly' onto gas. "nothing at all happened. " I push a bit harder and it crank into another gear as I felt like 'galloping'. I brought it to the body shop I knew (8 pm) and was told to go to dealers for transmittion check up. Did so, in 3 days - 'no code' no problem. It happened in November 2012; trying to catch up with traffic on 401 highway - March 2013, moving slowly in scity street - June and oct 2013; from stop - April 2014, June 2015 and about to stop before traffice light - may 2016. I brought it into 2 different delears, 3 private bodyshops. Dealers found nothing - 'no code'; private body shop - water/ air trapped in gas/ fuel line; bad transmission etc. Contacted Ford customer sevices - told to contact local delears, record on file. No solution still. This is Ford!!!! once get the chance - go anything other than Ford!!.
Engine had massive top engine detonation (backfire) with only 7500 miles on new car. Ever since this event the car shudders, stammers, shakes and does not want to accelerate smoothly. The problem varies in daily severity and is always worse in wet, heavy moisture periods. I have taken the car to five (5) different Ford dealerships and they all say there is no problem because there are no codes indicating a problem. One of the Ford dealerships went to great lengths to fix the car but to no avail. They rebuilt the transmission because they thought it was a failure to downshift. They later replaced three different sensors on this ecoboost engine (they said there are 33 different sensors) and this actually gave temporary improvements, but this was also in the very dry dallas summer. As soon as I drove back across arkansas to tennessee the car was as bad as before. This car actually gets 14. 2 miles per gallon combined driving and it was rated at 18mpg (16city and 21highway). The car averaged 18. 6mpg for the 7500 miles prior to the problem. I have put up with this problem for over three years but I have learned to not drive the car in the rain. There are other family cars that I can drive or I would have pulled my hair out. This problem was elevated to Ford customer service on several occasions (4 or 5 different times) and they never took ownership of the problem or the process. There appears to be a firewall established between the Ford technical group and Ford dealership service departments. Several service people complained that they could not contact Ford technical people directly and that it required a failure code entry into the service system without solution to facilitate contact with technicians and engineers. No code no problem! I sure am glad they have a code for every situation!.
