NHTSA Complaint #11499971 — 2016 FORD FLEX

Ford hid the fact that some of its vehicles may suffer a sudden internal water pump failure that poses significant safety risks to drivers including sudden catastrophic engine failure. From 2007 through at least 2020, Ford has incorporated the Cyclone Engine—containing a faulty internal water pump—into thousands of vehicles. Internal Water Pumps should last for the useful life of the engines without the need for any service, maintenance, or repair. Despite knowing for more than a decade that its' vehicles incorporating the "Duratec Engine", contain a defect in design that can cause the internal water pump to prematurely fail well before the end of the useful life of the engine. The issue has lead to a repair estimate of $2700 USD or could lead to catastrophic engine failure due to the water pumps' placement inside the engine block (Poor Design). In the past, Ford has also represented that the water pump will not need to be serviced or maintenance, but the internal location of the water pump in the engine conceals it from view and inspection when other routine services are being performed. The water pump is in line with the crankshaft and located over the main body of the engine, it reportedly allows coolant to leak from the water pump into the oil pan. Making matters worse, mixed coolant and oil can lead to engine failure, too.
