NHTSA Complaint #10247341 — 2003 FORD F-150

ANTI-LOCK BRAKE FAILURE - FAILURE OF ELECTRONIC HYDRAULIC CONTROL UNIT WHILE BRAKING A FEW WEEKS AGO I WAS DRIVING ON A HIGHWAY AT ABOUT 65-70 MPH WHEN A CAR ON THE SIDE OF THE ROAD STARTED TO PULL ONTO THE HIGHWAY. I WAS ONLY ABOUT 200 FEET AWAY FROM THE CAR SO I SLAMMED ON MY BRAKES - IT SEEMED LIKE THE CAR WAS GOING TO STOP PULLING OUT SO I LET GO OF THE BRAKES FOR A SECOND BUT THEN THE OTHER DRIVE DID PULL RIGHT IN FRONT OF ME AND I SLAMMED ON THE BRAKES AGAIN. THE SECOND TIME THE ABS LIGHT CAME ON, THE REAR WHEELS LOCKED UP AND THE CAR BEGAN TO FISHTAIL. ONLY BECAUSE THERE WASN'T ANY ONCOMING TRAFFIC WAS A COLLISION AVOIDED. THE LIGHT NEVER TURNED OFF, AND THE BRAKES BEHAVE ERRATICALLY. A FRIEND IS A MECHANIC WHO USED A SNAP-ON SOLUS DIAGNOSTIC TOOL WHICH SHOWS THE ABS DHCU SEES THE CAR MOVING AT 3-4 MPH WHILE PARKED, THE SYSTEM OFF, BUT WHEN YOU DRIVE THE CAR IT APPLIES THE ABS SYSTEM WHILE SLOWING BELOW ABOUT 5MPH UNDER NORMAL DRIVING (LIKE APPROACHING A STOP LIGHT) INCREASING THE STOPPING DISTANCE CONSIDERABLY. THE MODULE DOES NOT RESPOND TO RESET ATTEMPTS, AND REPAIR IS BY REPLACEMENT ONLY. THE CAR IS A SPECIAL PRODUCTION FORD F150 LIGHTNING, WITH A DHCU SPECIFIC TO THE LIGHTNING EDITION. REPLACEMENT OF THE MODULE IS ABOUT $700 PLUS LABOR. THE VEHICLE ONLY HAS 16,000 MILES ON IT, ABOUT 15,500 WHEN THE INCIDENT OCCURRED. *TR
