 I purchased a 2010 Ford Edge, kept up with normal maintenance and at 65K miles had a water pump failure. Normally not a big deal BUT Ford designed the Duratec 3.5L motor with an internal water pump driven by the timing belt (really poor design) so when the water pump fails it dumps your coolant into the motor crank case and your motor also fails! $5000 repair bill for a WATER PUMP FAILURE! While I was at Ford there was a Ford Flex (same motor) there with same problem at 74K miles! POOR DESIGN! BUYER BEWARE!
