Owner Narrative

I am submitting a formal safety complaint regarding a severe design defect in the 3.5L V6 engine of my 2013 Ford Explorer. The vehicle is equipped with an internal, chain-driven water pump that is currently failing at 100000 miles, as evidenced by coolant actively draining from the factory weep hole. Because this pump is located inside the engine block and driven by the timing chain, a complete seal failure dumps engine coolant directly into the oil pan. This is a critical safety hazard. When the coolant and oil mix, it destroys the engine bearings and causes the engine to completely seize without warning. If this sudden engine seizure occurs while driving at highway speeds, it results in an immediate and total loss of motive power, power steering, and power brakes. This defect creates an extreme crash hazard for the occupants of the vehicle and other drivers on the road. The internal weep hole provides virtually no dashboard warning or indicator to the driver before this catastrophic failure occurs. I am requesting that the NHTSA investigate this known, dangerous design flaw to force a mandatory safety recall before this sudden loss of vehicle control causes severe injuries or fatalities.
