NHTSA Complaint #10402988 — 2010 FORD FLEX

2010 FORD FLEX BAD BRAKE ISSUE. I LIVE AT HIGH ALTITUDE AND HAVE A FORD FLEX ECO BOOST THAT PERFORMED FLAWLESSLY UP UNTIL ABOUT 21K MILES WHEN WE HAD A BRAKE FAILURE, THE BRAKES DID NOT STOP THE CAR. THE DEALER REPLACED A MASTER BRAKE BOOSTER AND SINCE THAT TIME WE INTERMITTENTLY GET A HARD BRAKE PEDAL AND NO MATTER HOW HARD YOU PUSH THE PEDAL THE CAR WILL NOT STOP. THERE IS ANOTHER PERSON ALSO LIVING AT THE SAME ALTITUDE ABOUT 9,200 FEET IN SUMMIT COUNTY CO WHO HAD THE EXACT SAME SERIES OF EVENTS ALTHOUGH CURRENTLY HE IS DOWN IN TEXAS WITH NO ISSUES. A THIRD PERSON IN WYOMING WHO IS ABOUT 6,000 FEET IS HAVING THE SAME PROBLEM. FORD CLAIMS THERE IS NOTHING WRONG WITH THE CAR AND HAVE SENT TWO ENGINEERS TO LOOK AT IT WHO HAVE NOT EXPERIENCED THE HARD PEDAL BUT THE GM AT THE DEALER HAS, NEVER THE LESS EVERY ONCE IN A WHILE ESPECIALLY WHEN FIRST STARTING OUT THE BRAKE PEDAL IS HARD AND YOU HAVE ABOUT 10% BRAKING. MY WIFE ACTUALLY WENT THROUGH A RED LIGHT FOR ABOUT 20 FEET BEFORE SHE COULD FINALLY STOPPED SHE WAS LUCKY NO CAR WAS COMING AT THE TIME. IT ONLY HAPPENS AT HIGH ALTITUDE APPARENTLY. WHICH MEANS THAT PEOPLE DRIVING UP INTO THE MOUNTAINS TO GO SKIING OR WHATEVER MAY GET AN AWFUL SURPRISE IF THEIR BRAKES FAIL. I HAVE POSTED UNDER THE WWW.FORDFLEXFORUM.COM AND WWW.FORDFLEX.NET WHERE YOU CAN SEE THE REPLIES FROM OTHERS WITH THE SAME PROBLEM. AS THIS PROBLEM DID NOT OCCUR UP UNTIL ABOUT 21K MILES FOR ALL THREE CARS I KNOW ABOUT THERE HAS TO BE A DEFECTIVE PART SOMEWHERE. WE ARE RELUCTANT TO USE THE CAR AND ARE WORRIED ABOUT CONSEQUENCES IF WE WERE TO HAVE AN ACCIDENT. WE HAVE REPORTED DIRECT TO FORD AND HAVE A CONTACT WITH THEIR CUSTOMER SERVICE, THE LATEST ADVICE HIRE AN INDEPENDENT ENGINEER TO VERIFY THEIR IS AN ISSUE. I FIGURED I WOULD TRY THE GOVERNMENT.
