On June 9, 2026, the vehicle received a PCM reprogramming under Ford Recall 21E01. Before the update, the transmission had no symptoms: no slipping, no warning lights, and no diagnostic trouble codes. Between June 9 and August 11, the vehicle accumulated 1,894 miles. On August 11, 2026, while driving about 60 mph, the vehicle suddenly downshifted from sixth to fifth gear without input. A clunk was felt, followed by complete loss of all gears. There were no warning lights, no diagnostic trouble codes, and no limp‑mode activation. The failure was sudden and total. A diesel shop retrieved the strategy values after the incident, which showed no recorded indication of transmission degradation prior to the PCM update. The failure occurred less than 2,000 miles after the PCM reprogramming. The vehicle was in factory‑stock condition. The incident raises concern that the updated PCM calibration may have affected torque calculation, shift coordination, or diagnostic monitoring, resulting in an uncommanded downshift and loss of all gears without protective response.

Vehicle Commanded Engine Shutdown
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 the federal safety agency will take further action if such action is warranted.

The back up camera on my F350 froze the image on the screen as I was backing up, and I didn’t realize that I had backed into my daughter’s car. I ripped my fender off and wedged my tires up underneath her CRV there was no warning and I didn’t realize there was a recall on it because I hadn’t gotten anything in the mail. I did it my own driveway so I didn’t call the police and I haven’t turned on insurance yet. I wanted to see what I needed to do
