WHILE DRIVING IN SPEEDS BETWEEN 55-70 AND DRIVING OVER A BUMP, BRIDGE OR POTHOLE, MY FRONT END WOULD SHAKE VIOLENTLY; RESULTING IN NEARLY LOSING CONTROL OF THE TRUCK. I WOULD NEED TO COME TO A COMPLETE STOP IN ORDER TO END THE VIOLENT SHAKING. THIS HAPPENED NEARLY 15 TIMES WHEN DRIVING EASTBOUND ON I-40 BETWEEN NASHVILLE AND KNOXVILLE TN. I WAS LUCKY ENOUGH TO HAVE AN EMERGENCY SHOULDER AND LIGHT TRAFFIC OR ELSE IT MAY HAVE CAUSED A DEADLY ACCIDENT. I HAVE RESEARCHED THIS ISSUE AND MOST CALL IT 'DEATH WOBBLE' AND IT IS CAUSED BY THE CASTOR ANGLE OF FORDS FRONT END SUSPENSION. IT IS KNOW TO RAPIDLY WEAR BUSHINGS, JOINTS AND BEARINGS THAT COULD ULTIMATELY CAUSE LOSS OF TOTAL CONTROL OF A HEAVY DUTY VEHICLE. MULTIPLE TSB HAVE BEEN ISSUES FOR OTHER YEAR OF SUPERDUTY TRUCKS AND ALL HAVE STATED TO REPLACE WORN TRACK BARS, TIE ROD ENDS, STEERING STABILIZERS AND ADJUST THE CASTOR ANGLE.

I HAVE HAD REPAIRS TO MY TRUCK 3 TIMES IN THE LAST 2 YEARS TO FIX THIS CAUSING ME APPROXIMATELY $1000 EACH TIME. MOST RECENTLY MONDAY JULY 9, 2018. THE 'REPAIR' SEEMS TO BE ONLY TEMPORARY AND EACH TIME I HAVE IT FIXED IT LASTS 6-9 MONTHS. THE DEALERSHIP IS UNWILLING TO HELP NOR IS FORD CUSTOMER COMPLAINT DEPARTMENT. THIS HAPPENS WHILE DRIVING 55-65 MPH AND AFTER HITTING A BUMP.

THE TRUCK SHAKES VIOLENTLY AT TIMES AFTER A BUMP IN THE ROAD. OUR TRUCK WENT BACK TO THE DEALER SEVERAL TIMES WHILE UNDER WARRANTY FOR THIS HOWEVER THEY SAID SINCE IT COULD NOT BE REPRODUCED CONSISTENTLY NOTHING COULD BE DONE. IT HAS GRADUALLY GOTTEN WORSE - MUCH WORSE. LAST SUMMER IT GOT SO BAD IT WAS SCARY TO DRIVE SO WE TOOK IT TO ANOTHER MECHANIC WHO PUT NEW SUSPENSION PARTS IN THE FRONT END. AFTER A COUPLE THOUSAND IN REPAIRS AND MANY NEW PARTS, IT STILL SHAKES SO VIOLENTLY WE CANNOT DRIVE IT SAFELY. FORD KNOWS ABOUT THESE COMPLAINTS - THEY ARE ALL OVER THE INTERNET AND ON THIS SITE SO WHY CAN THIS NOT BE FIXED? I DROVE MY GRAND-DAUGHTERS IN IT ONE DAY TWO WEEKS AGO AND AFTER NOT HAPPENING FOR DAYS IT HAPPENED AND IT'S A WONDER WE DID NOT HIT THE ONCOMING CAR HEAD ON. SOMEONE IS GOING TO DIE IN ONE OF THESE TRUCKS AND THEN MAYBE FORD WILL STEP UP AND AT LEAST TELL THOSE OF US THAT OWN THEM HOW TO FIX THIS PROBLEM! IT SEEMS LIKE IT RARELY HAPPENS AT 40 MPH OR BELOW BUT HAPPENS QUICKLY AT 55 MPH OR MORE. IF SOMEONE DIES FROM THIS "DEATH WOBBLE" IT SHOULD BE FORD'S RESPONSIBILITY.

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.
