The contact owns a 2011 Ford Flex. The contact stated that upon her husband starting the vehicle, the vehicle entered limp mode as he exited the driveway. Her husband then drove the vehicle back into the driveway and turned the vehicle off. The next day, her husband started that vehicle and was temporarily able to resume normal driving; however, the vehicle entered limp mode while in traffic as the power train warning light illuminated. Her husband was able to coast the vehicle back home while in limp mode and had the vehicle towed to a dealer. The dealer initially diagnosed the vehicle with a defective throttle body; however, the failure persisted after the part was repaired. The contact made numerous trips back to the dealer; however, the failure persisted after each visit. The contact was then informed to take the vehicle back once the wrench light had illuminated. Once the wrench light illuminated, the contact began to drive the vehicle to the dealer. While driving, she heard an abnormal clunking sound coming from the vehicle as the check engine warning light illuminated and the vehicle entered limp mode. The contact made it to the dealer as antifreeze began leaking from the vehicle. The contact was then informed by the mechanic that the radiator fluid had begun to leak out of the vehicle as a result of the water pump, which was previously replaced. The mechanic also discovered that the radiator fluid had leaked out of the rear main seal of engine which caused engine failure. The manufacturer was notified of the failure and provided the contact with a case number. The vehicle remained at the dealer and was not repaired. The failure mileage was approximately 112,000.

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.
