WHILE TRAVELING IN THE LEFT HAND LANE ON 1-4 IN FLORIDA, WE RECEIVED A "STOP VEHICLE SAFELY NOW" WARNING AND THEN WITHIN SECONDS THE TRUCK SHUT DOWN. I WAS FORCED TO MAKE MULTIPLE, UNSAFE LANE CHANGES IN HEAVY TRAFFIC TO GET THE VEHICLE TO THE RIGHT SIDE OF THE INTERSTATE WITH WHAT POWER I HAD LEFT. MY PREGNANT WIFE AND 3 YEAR OLD SON WERE IN THE CAR WITH ME. WE WERE 3 HOURS FROM HOME AND ANY FAMILY / FRIENDS WHO COULD HELP. THE TRUCK WOULD NOT RESTART AND HAD TO BE TOWED TO A LOCAL DEALERSHIP WHICH CHARGED US $800 TO REPLACE 3 SENSORS AND GET THE TRUCK BACK ON THE ROAD. FURTHER, THEY WERE NOT ABLE TO REPAIR THE VEHICLE UNTIL THE FOLLOWING DAY, LEAVING US STRANDED IN A FOREIGN CITY. THE DEALERSHIP WAS VERY CLEAR THAT THE ISSUE WAS SIMPLY A SENSOR AND THERE IS NO REASON THE TRUCK SHOULDN'T HAVE JUST GIVEN US A CHECK ENGINE LIGHT WHICH WOULD HAVE ALLOWED US TO GET HOME. WE WERE TOLD BY THE DEALER AND SEVERAL FRIENDS WHO HAVE THE SAME MAKE AND MODEL THAT THIS IS A COMMON OCCURRENCE AND FORD HAS NO INTENTION OF FIXING THE PROBLEM. THIS COULD HAVE CAUSED AN ACCIDENT AND I AM EXTREMELY DISAPPOINTED THAT FORD WOULD KNOWINGLY PUT MY FAMILY IN DANGER. *TR

WHEN TRYING TO ACCELERATE, THE TRANSMISSION WOULD RANDOMLY DEVELOP A PROBLEM WHICH SEEMED LIKE IT WAS TRYING TO FIND THE RIGHT GEAR. THERE WOULD BE A SEVERE LOSS OF POWER WHICH WOULD RESULT, AT TIMES, LEAVING MY VEHICLE IN TRAFFIC GOING AT A MUCH HIGHER SPEED AND CLOSING RAPIDLY FROM BEHIND. THE PROBLEM WAS RESOLVED BY DOING THE SERVICE PRESCRIBED IN THE SERVICE BULLETIN BUT I WAS NOT AWARE OF THAT BULLETIN UNTIL THE PROBLEM BECAME SEVERE. *TR

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.
