Water pump, engine. All of a sudden out of the blue with no indications, warning, leaks, stalls, rough driving, no starts, lights or smells; sent to start car and it was making a metal grinding/rattling sound and would not start. I had it towed over to the ford dealer and 2 days later they looked at it. They stated the water pump catastrophically failed, leaked into the oil pan, overfilled the oil pan and cause coolant/water to be circulated through engine causing no compression and seizing the engine. The dealership said it would have happened pretty quick. I am now in need of a new engine because of the water pump design flaw of fords water pump emptying into the oil pan. Ford customer service says there is no recall or complaints in the federal safety agency database so it is not a problem. But I have gone online and seen this exact complaint from people in many forums, on multiple models. This catastrophic water pump failure and design flaw has been going on for 11 years and ford refuses to do anything about or to help the customer. This is not getting reported correctly or in the right place or simply service centers dont report to this database therefore ford closes thier eyes to problems. I am just glad this did not happen to my wife on her trip to michigan at night on the weekend with kids in the car. It must be an issue if I can find class action lawsuits on thei exact issue. Hold ford responsible, they are going to kill someone or their families.

I have full documentation from ford to back up my story: last year the car began stalling intermittently. In buffalo, ny (we live in the chicago area). The stalling got so bad that she was worried about driving back home 10-hours+. She went into the local dealer there and had the car plugged into the computer...which detected no faults. She made sure to describe the problem fully and it is documented on the receipt. The car has continued to have this problem. I read that the ford dealer can install a "black box" with a button that one can push when an intermittent problem happens. We did this and we got three good pushes of the button when it subsequently stalled and the dealer downloaded the info and found that the throttle body is faulty....of course the car (we had extended service plan) is now out of warranty for about 1.7k miles (not time). Note that the car failed to trigger the check engine light...it was only at my insistence that they put in a "black box" that any problem was found. The ford customer care person on the phone keeps telling me that "the current problem" occurred after the car was out of warranty. But our documented maintenance history proves that this is a problem dating from last year. This is a year-old problem that the dealer was only just able to diagnose...and then only because I learned about the "black box" that was available. The bottom line is that the dealership failed to find the problem last year, and because they failed to find the problem we are now on the hook for the repair. I have copies of the receipt from last year. Oh, and to add insult to injury my wife had to pay ford $108.70 for them to plug the car in last year... The car never had a check engine light or displayed fault codes when plugged into the computer normally. It would have been nice if the black box was suggested as a diagnostic option however.

While accelerating from a stop with the ecoboost system , the car will almost stall, then speed up with out your foot on the pedal. It blows black smoke and then it will be fine. This has happened on and off for the past several months, the car had an extended warranty in which this showed up. While this was going on I have had to replace the power transfer unit because it locked up, then the car would only work in front wheel drive, have had nothing but trouble since the car radiator fan system burned up and they replaced. They have re-flashed modules after they could not figure out what was happening, however it still does it. I am worried as the car has speed up to 2000 RPM while driving and stayed there with out the gas pedal being pressed.

Our 2011 ford flex we bought "new" in october of 2010. It has all the bells & whistles & had a sticker price of almost $51,000 dollars! This car doesn't like to get wet! It stalls in the snow, rain, car wash & even puddles! It just "shuts down" in the middle of an intersection.....it will "putt putt" & almost stall on highways. We came sooo close to getting killed! Ugh....we have taken this car in to (metro ford in raynham) at least "4" times. The last time was just a couple of months ago & it was there for "4 weeks"! Then this was it.........we had to take our 19 yr old daughter to the er last thurs. She fainted & hit her head hard! This car stalled all the way to the hospital!! We almost didn't make it there!! This car is a lemon!!! We want this car replaced!!!
