2017 Ford Expedition

Vehicle has 124,058 miles. On this date - Oct 14, 2021, brake pedal got soft, audio and visual warning saying low brake fluid level. Luckily was just slowly pulling into driveway after driving at 55-60 on US 341. Checked brake fluid level. It was indeed very low. Added DOT4 fluid. Drove vehicle slowly in back area and depressed brake pedal several times. Pedal still not quite right. Thought maybe had air in lines. But soon audio/visual warning came on. Checked brake fluid level. Low again. Looked underneath for any obvious leaks - none. Check fire wall - nothing. So assumed fluid was going in to booster. Looked on internet and found other complaints just like this. This is EXTREMELY dangerous. Has anyone been killed yet? The brake parts need to be built like aircraft parts.

Brake failed in parking lot and vehicle crashed into another car. A low brake fluid light came on and very shortly (1 minute) after the brake failed completed. Vehicle was serviced at dealer two months ago. Contacted Ford corporate and Ford dealer. Ford corporate said there is nothing they can do. Ford dealer unresponsive. This is a major safety issue. I have never heard of real issues with complete brake failure on a newer car. Very dangerous.

Wife started car. Pushed on the brake to put it in gear. Brake pedal went to floor. Checked master cylinder. Cylinder was completely empty. Brake fluid leaked past seals in master cylinder into the brake booster, then got sucked into engine and burned. No warning lights came on at all.. Luckily wife was at the pool down the road from our house when it happened. She drove 5 mph back to the house. A four year car should not have a faulty brake master cylinder. Master cylinders should last for at least 10 years. Ford has a major problem brewing.

TOTAL BRAKE FAILURE WHILE BACKING UP , ALMOST HIT ANOTHER VEHICLE, SHIFTED TO FORWARD TO AVOID ACCIDENT , LOSS OF BRAKE FLUID IN MASTER CYLINDER TO BRAKE BOOSTER. EXACT SYMPTOMS AS RECALL 20S31 WITH 2014 TO 2017 F150. THE EXPEDITION IS ON AF150 CHASSIS . ACCORDING TO DEALER NOT UNDER RECALL BUT PROBABLY SHOULD BE. OUT OF WARRANTY. REPAIRED ON MY DIME. REPLACED MASTER CYLINDER AND CLEANED BOOSTER. VEHICLE WAS IN MOTION AT TIME OF INCIDENT. JUST GLAD I WASN'T ON THE BOAT RAMP OR HIGHWAY

THE BRAKE SYSTEM WENT OUT WHILE DRIVING MY 2017 FORD EXPEDITION. THE WARNING LIGHT CAME ON INDICATING LOW BRAKE FLUID. I CALLED FORD ABOUT THE ISSUE TO WHICH THEY TOLD THE ISSUE WAS NOT COVERED UNDER THE WARRANTY. AFTER SOME RESEARCH THERE IS A RECALL ON THE MASTER BRAKE CYLINDER AND BRAKE BOOSTER SYSTEM ON THE F150 ECOBOOST. NHTSA CAMPAIGN NUMBER: 20V-332. FORD'S REFERENCE NUMBER FOR THIS RECALL IS 20S31. THE MY EXPEDITION HAS THEY SAME ISSUE . THE F150 AND EXPEDITION ARE THE SAME UNDER THE HOOD. THE VEHICLE IS SAFETY HAZARD DUE TO THIS ISSUE.

TL* THE CONTACT OWNS A 2017 FORD EXPEDITION. THE CONTACT STATED THAT WHILE IN THE DRIVE WAY THE CONTACT STARTED THE VEHICLE AND DEPRESSED THE BRAKE PEDAL TO PLACE THE GEAR SHIFTER INTO DRIVE AND WITHOUT WARNING THE BRAKE PEDAL WENT TO THE FLOOR. THE VEHICLE WAS TOWED TO SARASOTA FORD LOCATED AT (707 S WASHINGTON BLVD, SARASOTA, FL 34236, (941) 366-3673, WHERE IT WAS DIAGNOSED AND DETERMINED THAT THE BRAKE BOOSTER NEEDED TO BE REPLACED. THE REPAIR WAS STILL PENDING. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE BUT NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS APPROXIMATELY 54,000. THE VIN WAS NOT AVAILABLE.

EXITING THE 215 NORTHBOUND, WE STOPPED AND PARKED AT A STORE. WHILE PARKED THE INDICATOR LIGHT CAME ON FOR LOW TIRE PRESSURE. I DID NOT PAY THAT MUCH ATTENTION BECAUSE THE CAR INDICATOR LIGHT HAS COME ON BEFORE AND THE CAR HAD RECENTLY HAD ITS ROUTINE MAINTENANCE CHECK. WHEN DRIVING WAS RESUMED THE CAR BEGAN TO WOBBLE. ASSUMING WE HAD A FLAT, WE ATTEMPTED TO DRIVE TO A MORE ILLUMINATED AREA TO INSPECT THE CAR AND CALL ROAD SIDE SERVICES. THE CAR AT THIS POINT WAS BEGINNING TO DECELERATE ALMOST TO A STOP SO I INCHED CAR ONTO AN UNPAVED AREA. I ASSUMED THE CAR'S SLOWING AND STOPPING ON ITS OWN WAS A SAFETY FEATURE. AS I PULLED TO THE SIDE OF AN UNPAVED CITY ROAD, I HAD MY FOOT ON THE BRAKE BUT NOT IN THE PARKING GEAR. THE CAR WAS STATIONARY AS MY SISTER EXITED THE CAR AND TO INSPECT THE TIRES. THE RIGHT REAR PASSENGER TIRE WAS FULLY DEFLATED. MY TWO DAUGHTERS WERE ABOUT TO GET OUT OF THE CAR SO HAD UNFASTENED THEIR SEATBELTS. THIS IS WHEN THE CAR MADE A QUICK SUDDEN JERK FORWARD, I PRESSED MY FOOT ON BRAKE TO MAKE SURE THE CAR WAS AT A COMPLETE STOP AND THAT WAS WHEN IT FELT LIKE A FORCE HAD PUSHED THE CAR TO TOP SPEED, AN SUDDEN UNINTENDED AND FORCEFUL ACCELERATION. I ATTEMPTED TO BRAKE BUT I HAD NO CONTROL. I WAS TRYING TO AVOID HITTING THE POLE, BUT ALSO HAD NO CONTROL OVER THE STEERING WHEEL. THE CAR COLLIDED WITH A WATER VALVE/POLE AND CHAIN LINK FENCE AT TOP SPEED.

THE BRAKES WENT OUT SUDDENLY. AFTER TAKING TO A MECHANIC WE WERE INFORMED THAT THE MASTER CYLINDER HAD A CATASTROPHIC FAILURE WHICH RESULTED IN LEAKING BRAKE FLUID CORRODING THE BRAKE BOOSTER. RESEARCH HAS LED ME TO BELIEVE THAT THIS IS A COMMON PROBLEM FOUND IN THESE VEHICLES. THANKFULLY MY WIFE WAS ONLY BACKING OUT OF THE DRIVEWAY WHEN IT HAPPENED SO SHE DID NOT HAVE AN ACCIDENT.
