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.
Got in car after stopping at grocery store and smelled gas, thought it might be from a nearby gas station. Got home and parked car in garage and about an hour later went in garage to take out trash. Garage had heavy smell of gasoline. Opened garage door, parked car outside and gasoline smell in garage went away. Took car to Ford dealer and car was diagnosed with a split/leaking fuel rail on top of engine. Had to have metal fuel rail replaced.
