NHTSA Complaint #11258449 — 2019 FORD EXPEDITION

1 . AFTER A LEFT TURN THE VEHICLE CONTINUES TO PULL LEFT (MEASURED AT ABOUT 4 POUNDS OF FORCE ON THE STEERING WHEEL TO HOLD STRAIGHT) UNTIL A RIGHT TURN IS MADE TO CANCEL THE LEFT PULL THEN IT TRACKS STRAIGHT. THERE WERE SIMILAR RESULTS ON RIGHT TURNS BUT WORSE ON LEFTS. 2 . THESE TESTS WERE ALSO DONE ON ANOTHER NEW FORD PLATINUM EXPEDITION IDENTICALLY EQUIPPED WITH THE SAME RESULTS (BOTH WITH HEAVY DUTY TOW PACKAGE) 3 . THE NEW EXPEDITION ABOVE DID SEEM TO REQUIRE A LITTLE LESS RIGHT CORRECTIVE PRESSURE THAN OUR EXPEDITION BUT THE LEFT PULL WAS APPROXIMATELY THE SAME 4 . THESE TESTS WERE DONE WITH AND WITHOUT LANE KEEPING WITH NO CHANGE TO THE RESULTS 5 . THESE TESTS WERE DONE WITH AND WITHOUT SWAY CONTROL WITH NO CHANGE TO THE RESULTS 6 . APPROXIMATE TRAILER WEIGHT 6000 LBS. AND APPROXIMATELY 600 LBS. TONGUE WEIGHT 7 . DURING THE LEFT PULL THE VEHICLE WILL 'BLOW' THROUGH THE LANE KEEPER ON THE LEFT BUT WORKS OK ON THE RIGHT 8. TESTS WERE ALSO MADE WITH A TOTALLY DIFFERENT TRAILER AND HITCH SYSTEM WITH THE SAME PROBLEM. 9. THE TESTS WERE DONE WITH AND WITHOUT LOAD TRANSFER BARS. THE LEFT PULL REMAINED AFTER A LEFT TURN BUT WAS A BIT LESS WITHOUT THE LOAD TRANSFER BARS ATTACHED (THAT WAS SURPRISING). 10. FORD HAS REPLACED THE ENTIRE STEERING SYSTEM (INCLUDING RACK AND PINION UNIT WITH STEERING CONTROL MODULE AND YAW SENSE MODULE) AFTER THEY CHECKED ALL WHEEL ALIGNMENTS WITH NO IMPROVEMENT IN STEERING PROBLEM. 11. THIS PROBLEM ALSO HAPPENS WITH NO TRAILER IN TOW JUST NOT TO THE SAME EXTENT. 12. FORD HAS NOW REFUSED TO DO ANYTHING MORE TO RESOLVE THE STEERING PROBLEM. NOTE: I DO HAVE VIDEO FOR THIS PROBLEM ON THE ROAD.
