I was happy with the ride and feel until I hit 20K, and noticed a momentary grinding when I applied the brakes.
Sometimes a gaslike smell was noticed after breaking.
Quite a bit of black dust seemed to accumulate on the two rear wheels.
At 25K a periodic squeal was noticed but the Ford dealer inspected and said the brakes were "good".
At 29.5K the brakes made a grinding sound and were visably scored (rear left).
My Ford Dealer said that "it wasn't a Ford problem because he didn't have a service
bulletin that dealt with this problem!".
Rather than have him repair with duplicate Ford parts, I took the car to a Goodrich dealer for new rear rotors and new upgraded pads.
The Ford Flex has a smooth ride and in a sense is a comfortable small truck (all seats fold down).
When I am transporting adults they fit comfortably in the middle set of seats.
The heated front seats are especially appreciated during the winter months. The sound system is a pleasure to use (there is no need for Sirous radio when you have a good CD player on board).
Make the steering wheel more adjustable (forward and back) so that the driver's seat doesn't need to be used to compensate for arm-length comfort.
Having to move the seat forward makes it difficult to step out of the car without having to constantly re-adjust the seat.
I had the same rear brake problem at around 44K and Ford would not stand behind the fact that their OEM brakes are failing on these cars - forcing owners to spend $100's to fix something that the factor should fix due to poor parts and/or design.
