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
