Internal Water pump Failed causing immediate shutdown of vehicle. This water pump is internal to the engine and requires half of the engine be taken apart to be replaced. This affect all 3.5 and 3.7 Ford engines through 2021. Unlike traditional water pumps which are belt driven this one is driven by the timing chain. Thereby when failure occurs the engine shuts down. Coolant also leaks into the oil as a result possibly resulting in engine damage. Ford is fully aware of the defect and refuses to recall. Regardless of age or miles this is a defect especially with vehicles equipped with the internal plastic water pump.

so not convenient to keep running back and forth for a repair they (ford motor company should have taken care of. Let's be clear they know there is a problem and refuse to fix it. Talked to 2 people @ 1 800-241-3673 and the flat out told me they will not pay for the repair. I've had the car stall in an interesection and on the highway several times . Sometimes I have to turn the key switch 30 40 50 60 times or more to get it to start. The tsb from ford motor co. Says that when changing the battery in the 2007 lincoln mkz it will cause a problem with the ecm the brain causing the problems I described. I even told them about stalling on the highway and they still refuse to pay for the repair. They did fix my air bad out of warranty but won't fix this . I find this unacceptable and refuse to pay for it out of my own pocket. Can you help please affected cars would be 2007 lincoln mkz. Mercury milan and ford fusion. I'm sure it not an isolated problem. The problem started last year 2018 I don't remember the exact date I will put in the date box below the date ford motor company/ lincoln refused to do repair free of charge

Acceleration & cruise controlEngine & cooling

Approximately 1 month ago (in may, 2014), while in the parked position and in a parking space, no foot on brake or accelerator, my 2007 lincoln mkz (61,000 miles) engine suddenly revved up and began to thrust forward. I immediately hit my brake hard, which stopped the car prior to hitting the curb or other obstacles; however, had it not been for my quick reflex, I shudder to think what might have happened! There was a curb, a trash can, and a building directly in front of me, and had I not been able to stop the...

car, there's no doubt I would have plowed straight thru all! I researched the problem online, but found no recalls except on floor mats that get stuck. I don't have the factory installed floor mats in my car and doubt that this is my problem. I did find a few similar complaints about the racing, surging, accelerating engine issues occurring with this make & model. I printed out these complaints and took to my local ford dealership. They researched it as well and found no recalls and of course they offered to check out the car, inquiring about my extended warranty, if any. I've since had a few incidences of minor unprovoked engine racing while driving that didn't appear to be too critical; however, I have this situation on my mind while driving and the thoughts are unsettling! I don't know what to do at this point as I don't have money for expensive repairs! Are there any updates about recalls, etc. Concerning this situation as my life as well as the lives of others are on the line!
