NHTSA Complaint #11320421 — 2010 FORD FLEX

INTERMITTENT ELECTRICAL FAILURE OF THE ADVANCE TRAK TRACTION CONTROL SYSTEM CAUSES THE VEHICLE TO UNEXPECTEDLY PULL TO THE LEFT OR TO THE RIGHT WHILE UNDER ACCELERATION ON VEHICLE SPEEDS ABOVE 20 MPH WITHOUT INDICATION FROM THE TELL-TALE TO THE OPERATOR TO INDICATE THERE IS A PROBLEM OR INTERMITTENT FAILURE OF THE TRACTION CONTROL SYSTEM. THIS UNEXPECTED PULL TO THE LEFT OR RIGHT IS VIOLENT ENOUGH TO CAUSE THE VEHICLE TO VEER ACROSS THE CENTERLINE OF A LANE, POTENTIALLY CAUSING A RISK TO ONCOMING TRAFFIC AND WELL AS THE OPERATOR OF THE VEHICLE TO BECOME INVOLVED IN A CRASH. THE FAILURE WILL CONTINUE TO OCCUR INTERMITTENTLY WITHOUT INDICATION TO THE DRIVER UNTIL THE EVENT OCCURS FREQUENTLY ENOUGH DURING AN IGNITION CYCLE TO TRIGGER THE TELL-TALE TO INDICATE A FAILURE OF THE ADVANCE TRAK SYSTEM, BUT THIS TELL-TALE ON THE DASH ONLY STAYS LIT DURING THE CURRENT IGNITION CYCLE AND WILL NOT BE PRESENT ON THE NEXT IGNITION CYCLE, AGAIN FAILING TO INDICATE THE INTERMITTENT FAILURE OF THE ADVANCE TRAK TRACTION CONTROL SYSTEM VIA THE WARNING LIGHT TELL-TALE ON THE DASHBOARD.
