THE DEATH WOBBLE MY F-250 TRUCK HAS BEEN HAVING A DEATH WOBBLE SINCE I BOUGHT IT ,I FIRST TOOK IT IN TO FORD SERVICE DEPARTMENT WITH 10,212 VEHICLE MILES ON THE TRUCK BECAUSE OF THE DEATH WOBBLE , AND HAVE TAKEN THE TRUCK SEVERAL TIMES FOR THE DEATH WOBBLE SINCE THEN . FORD MOTOR COMPANY HAS NEVER FIXED THIS PROBLEM , THEY ONLY MAKE MINOR CHANGES "BANDAID" TO THE TRUCK AND IT IS STILL NOT FIXED , THEY KEEP PUTTING ME OFF AND SAY THERE IS NO SOLUTION TO THIS PROBLEM. I HAVE SEVERAL PAGES OF SERVICE REPAIRS FORD HAS PERFORMED BUT THEY HAVE NEVER FIXED THE DEATH WOBBLE . MY FORD F-250 STILL HAS LOW MILEAGE BUT IS NOT SAFE TO DRIVE. MY FAMILY AND I HAVE CAME VERY CLOSE TO A ROLL OVER AT 70 MPH ON THE INTERSTATE FROM WHEN WE HIT A BUMP IN THE ROAD. EVERY TIME THE TRUCK ROLLS OVER A BUMP AT ANY SPEED ABOVE 20 MPH IT GOES INTO A WOBBLE AND BECOMES VERY HAZARDOUS AND SCARY. WE BOUGHT THIS F-250 KING RANCH TO DRIVE AND ENJOY ON VACATIONS AND OTHER FAMILY TRIPS , BUT AT THIS TIME MY FAMILY AND I DON'T FEEL SAFE RIDING IN IT, NOR HAVING IT ON THE ROAD WAYS IN FEAR OF IT BEING A DANGER TO US AND OTHER DRIVERS OR PEDESTRIANS. THIS F-250 GOES INTO A DEATH WOBBLE WHEN ENCOUNTERING A BUMP IN THE ROAD , ON PUBLIC COUNTY ROADS, CITY STREETS , STATE HIGHWAYS AND ESPECIALLY INTERSTATES AT HIGHWAY SPEEDS. I HAVE CONTACTED OUR LOCAL DEALER SEVERAL TIMES ON THIS ISSUE WHILE THE VEHICLE WAS UNDER WARRANTY. I HAVE CONTACTED FORD MOTOR CORPORATION ON THIS ISSUES AS WELL. YET NEITHER ONE OF THESE ENTITIES OF FORD MOTOR COMPANY HAVE ASSUME RESPONSIBILITY . REGARDS

WHILE DRIVING AT APPROXIMATELY 75MPH ON AN INTERSTATE; AFTER HITTING A BUMP OR EXPANSION JOINT THE FRONT END WOBBLES UNCONTROLLABLY UNTIL THE SPEED IS REDUCED BY ABOUT HALF. I HAD A TRUSTED MECHANIC LOOK AT MY TRUCK AND HE SAID ALL FRONT END PARTS WERE IN GOOD CONDITION AND TIGHT. HE TALKED TO A DEALER WHO RECOMMENDED REPLACING THE STEERING DAMPER AS A CURE FOR THE "DEATH WOBBLE" ISSUE. I HAD THAT REPLACED AROUND THE FIRST OF FEBRUARY 2021. I HAD NOT DRIVEN THE TRUCK ON AN INTERSTATE AT SPEED SINCE THE REPLACEMENT UNTIL TUESDAY, MARCH 9, 2021. THE WOBBLE HAPPENED THREE SEPARATE TIMES WITHIN A SPAN OF TEN MINUTES SCARING THE DAYLIGHTS OUT OF ME AND NEARLY CAUSING TWO WRECKS. THE TRUCK IS HAZARDOUS TO DRIVE TO NOT ONLY MYSELF, BUT TO OTHER VEHICLES IN MY VICINITY WHILE ON THE ROAD.

WE HAVE HAD NUMEROUS INSTANCES OF "DEATH WOBBLE" STARTING AT A 75,000 MILES. ALL SUSPENSION IS STOCK, TIRES ARE STOCK. I HAD BROUGHT THE TRUCK TO THE DEALERSHIP 4-5 TIMES (UNDER WARRANTY) AND GOT THE TRACK BAR REPLACED, TRACK BALL BUSHING, AND BALL JOINT, STEERING DAMPER, INCREASE IN CASTER AND EVEN BOUGHT NEW STOCK TIRES TO PROVE OUT THE PROBLEM. I HAVE 125,000 MILES ON THE TRUCK NOW AFTER FIGHTING THIS ISSUE FOR YEARS AND HAVE REPLACED ALL ROD ENDS, TRACK BAR, BUSHINGS, STEERING DAMPER, ETC AND THE DEATH WOBBLE STILL PERSISTS. THIS IS CLEARLY A DESIGN ISSUE AND MAKES THE TRUCK DANGEROUS TO DRIVE. THE ISSUE OCCURS PRIMARILY AT HIGHWAY SPEEDS, WHILE MAKING A VERY SLIGHT LEFT TURN WHEN A SMALL BUMP IS DRIVEN OVER SUCH AS AN EXPANSION JOINT. THE SEVERE VIBRATION THAT SHAKES THE FRONT SUSPENSION VIOLENTLY BACK AND FORTH DOES NOT SUBSIDE UNTIL THE TRUCK IS UNDER ~20 MPH (NOT A SAFE CONDITION TO BE IN WHEN ON THE HIGHWAY). DURING THIS PERIOD YOU CAN NOT HOLD THE STEERING WHEEL UNDER CONTROL, CAN NOT CONTROL THE DIRECTION OF THE VEHICLE OR STOP QUICKLY IF REQUIRED. THIS 'DEATH WOBBLE' HAS OCCURRED APPROXIMATELY 20 TIME WITH THE LATEST OCCURRENCE HAPPENING TODAY.

AT HIGHWAY SPEEDS WHEN GOING AROUND A CURVE THE VEHICLE BEGAN SHAKING VIOLENTLY. FORD DEALER REPLACED THE DAMPER ASSEMBLY, FRONT SUSPENSION ARM BUSHING, INSTALLED 1 DEGREE ADJUSTERS, REPLACED THE TRACK BAR BUSHING, AND DID A FRONT END ALIGNMENT. TEN MONTHS LATER I EXPERIENCED A SIMILAR VIOLENT SHAKING WHEN GOING OVER BUMPS AT 75 MPH. THIS HAPPENED 3 TIMES IN A 2 DAY PERIOD. THE SHAKING WOULD ONLY SUBSIDE AFTER SLOWING DOWN TO LESS THAN 15 MPH. MANY OTHER F250 OWNERS HAVE EXPERIENCED THE SAME PROBLEM. THE SHAKING IS SO VIOLENT IS COULD EASILY CAUSE LOSS OF CONTROL AND AN ACCIDENT. THIS VEHICLE IS UNSAFE.

The Office of Defects Investigation (ODI) opened this RQ to investigate allegations that the scope and remedy of safety recall 13V-535 were inadequate. Recall 13V-535 was limited to a relatively small population of Ambulance Package vehicles and ODI received complaints of pickup trucks and Fire Engine Prep Package vehicles being affected by the same defect. Ford manufactured approximately 555,985 subject vehicles between February 22, 2010 and January 30, 2015 that may be affected by defective EGT sensors and Powertrain Control Module (PCM) software calibration. The subject vehicles are equipped with four (4) EGT sensors to monitor engine operating conditions. An EGT sensor fault may produce false exhaust over-temperature signals. If these signals are produced, the Powertrain Control Module (PCM) implements a Failure Management Effects Mode (FMEM) and the driver receives a Stop Safely Now (SSN) system warning on the instrument cluster message center. The FMEM triggers a 70% reduction in available engine power over a period of no more than 45 seconds, during which it may not be possible to accelerate or maintain vehicle speed. The PCM then commands the engine to shut down when vehicle speed reaches approximately 1 mph. There is no immediate restart capability. Depending on the PCM software calibration, ignition key position and ambient temperature conditions, the engine may not restart until the end of a 10-60 minute cool down period.Ford and its component supplier(s) made numerous changes to the PCM software calibration and the design, material and manufacture of the EGT sensors over the period of subject vehicle production. This continuous product improvement affected vehicle performance regarding the alleged defect. Ford acknowledges the defect condition in the subject vehicles but argues that an unreasonable risk to motor vehicle safety is limited to Ambulance Package and Fire Engine Prep Package vehicles where commanded shutdown could impact emergency response and patient care. Ford also argues that the defect trend is in decline. Ford also initiated a new safety recall (15V-175) to address the 13V-535 remedy concerns in the Ambulance Package vehicles and Fire Engine Prep Package vehicles. The 15V-175 remedy reprograms the PCM with a new software calibration that stops a single EGT sensor fault to cause the vehicle to enter the FMEM shutdown mode.Ford also initiated an EPA emissions recall (14E03) for all subject vehicles that reprograms the PCM with the software calibration employed in safety recall 15V-175. Finally, Ford initiated a Customer Satisfaction Program (15M01) providing extended warranty coverage of 8 years or 80,000 miles for the the EGT sensors on certain MY2011-2012 subject vehicles.Due to the EPA emissions recall, that had a 66.6% completion rate in Ford's December 2015 progress report to the EPA, the defect trend is in decline. ODI is not aware of any crashes, deaths or injuries related to the alleged defect.ODI believes the alleged defect poses a safety risk but notes that the EPA emissions recall is addressing the safety problem.Compelling issuance of a duplicate recall would not represent a wise use of agency resources.Accordingly, this Recall Query is closed.This action is not a finding that no defect exists and NHTSA will take further action if such action is warranted.
