WHEN TRAVELING OVER 50 MPH WHEN MY VEHICLE HITS A BUMP, I GET A "DEATH WOBBLE" WHERE THE FRONT END SHAKES UNCONTROLLABLY. THE ONLY OPTION THAT I HAVE IS TO SLOW THE VEHICLE DOWN TO 35 OR BELOW TO GET IT TO STOP. I'VE COME CLOSE TO EITHER LOSING CONTROL OR GETTING HIT FROM BEHIND ON SEVERAL OCCASIONS. I CAN REPLICATE THIS EVENT BY GOING OVER DIFFERENT BUMPS IN THE ROAD. I HAVE RE-ALIGNED MY VEHICLE, REPLACED THE BRAKE SYSTEM, INSTALLED A NEW STEERING DAMPNER, ROTORS, ETC, TO NO AVAIL. FORD DEALERSHIPS PLAY STUPID AND ACT AS IF THERE'S NO PROBLEM, I'VE TAKEN IT TO MULTIPLE MECHANICS AND THEY INSIST THAT IT'S FAULTY PARTS WITHIN THE STEERING AND SUSPENSION. WOULD LIKE TO HAVE IT REPAIRED IF POSSIBLE, BUT DON'T HAVE A LOT OF OPTIONS AS TO WHAT THE TRUE CAUSE IS. PLEASE ADVISE AS TO WHETHER OR NOT YOU HAVE ANY OTHER COMPLAINTS . THIS HAS BEEN AN ONGOING ISSUE SINCE I PURCHASED THE VEHICLE NEW IN 2011. IT HAS ONLY GOTTEN WORSE AS IT GETS OLDER.

VEHICLE IS EXPERIENCING "DEATH WOBBLE". DEALERSHIP INSTALLED KC3Z 3E651 B:DAMPER ASSY TO FIX THE ISSUE. PROBLEM RE-OCCURRED WITHIN WEEKS. TOOK IT BACK TO THE DEALER AND THEY COULD NOT EXPLAIN. THIS TIME THEY SAID THE TRAC BAR BALL JOINT NEEDED TO BE REPLACED. REPLACED IT AND HAD THE SAME PROBLEM RE-OCCURRING WITHIN DAYS. THIS PROBLEM OCCURS RANDOMLY WHEN DRIVING OVER MINOR BUMPS, ROAD SEAMS IN BRIDGES, ETC. WITH AND WITHOUT CARRYING A LOAD. INDICATIONS ARE HEAVY VIBRATIONS IN THE FRONT END/STEERING THAT WILL NOT STOP UNTIL YOU LET THE VEHICLE DE-ACCELERATE ON IT'S OWN WITHOUT USING THE BRAKE.

FORD IS RECALLING CERTAIN MODEL YEAR 2011 FORD F-150, F-250, F-350, F-450, F-550, EDGE, AND LINCOLN MKX TRUCKS MANUFACTURED FROM OCTOBER 25, 2010, THROUGH NOVEMBER 20, 2010. THESE VEHICLES WERE INSPECTED USING INTEGRATED DIAGNOSTIC SYSTEM (IDS) THAT HAD A CUSTOM SOFTWARE ROUTINE TO READ THE SUSPECT BODY CONTROL MODULE (BCM) SERIAL NUMBER. BASED ON THE SERIAL NUMBER THE BCM WAS EITHER NOT AFFECTED OR REPLACED. THE CUSTOM SOFTWARE ROUTINE WAS NOT READING THE CORRECT SET OF CHARACTERS, AND WAS NOT ABLE TO IDENTIFY A BCM THAT REQUIRED REPLACEMENT AFFECTED BCMS MAY HAVE THE POTENTIAL FOR AN INTERNAL SHORT.
Consequence & remedy
Consequence: IF AN ELECTRICAL SHORT DEVELOPS, AN OVERHEATING CONDITION MAY OCCUR WHICH COULD RESULT IN A VEHICLE FIRE.
Remedy: DEALER WILL INSPECT THE BODY CONTROL MODULE AND IF NECESSARY REPLACE IT FREE OF CHARGE. THE SAFETY RECALL BEGAN ON MARCH 7, 2011. OWNERS MAY CONTACT FORD MOTOR COMPANY CUSTOMER RELATIONSHIP CENTER AT 1-866-436-7332.

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.
