2009 ford flex-complete brake failure after sitting for a period of time at high-altitude. brakes had felt spongy other times but we thought it was due to icy parking lot-as after driving a bit brakes felt ok. this time brakes failed completely resulting in property damage. car towed to local ford dealership -- they told us the brakes were fine and there have been no issues with brakes on the ford flex--which after researching we know to be false. the brakes still do not feel right upon start-up-brake pedal goes further down before stopping; we now wait a period of time before driving--we are afraid to drive car but don't have the money to purchase a different automobile-and don't want to pass a dangerous car to another family. *js
