NHTSA Complaint #10478638 — 2011 FORD EXPEDITION

TRAVELING DOWN THE HIGHWAY GOING APPROXIMATELY 70 MPH WHEN THE REAR WHEELS LOCKED CAUSING THE VEHICLE TO RAPIDLY DECELERATE AND REAR END TO SWERVE. FORTUNATELY THERE WERE NO VEHICLES IMMEDIATELY BEHIND THE VEHICLE AS THIS WOULD HAVE RESULTED IN A MAJOR REAR END COLLISION. THE REAR WHEELS UNLOCKED AFTER APPROXIMATELY THREE TO FOUR SECONDS AND I WAS ABLE TO COAST THE VEHICLE TO THE SHOULDER OF THE ROAD. THE POWERTRAIN MALFUNCTION WRENCH WAS LIT ON THE DASHBOARD AND THE VEHICLE WOULD NOT MOVE FORWARD IN ANY GEAR. I PUT THE VEHICLE IN PARK, SHUT OFF THE ENGINE AND RESTARTED THE VEHICLE. THE WRENCH ON THE DASHBOARD EXTINGUISHED AND I WAS ABLE TO DRIVE THE VEHICLE TO THE DEALERSHIP UTILIZING SECONDARY ROADS. THE DEALERSHIP HAD THE VEHICLE FOR THREE DAYS AND CONTACTED FORD ENGINEERING FOR TECHNICAL ADVICE. THE DEALERSHIP REPLACED THE MECHATRONIX UNIT AND INSPECTED THE DRIVE TRAIN FOR IRREGULARITIES. *TR
