THE TRUCK SURGES/ENGINE REVS. FORD DOES NOT KNOW WHY ITS HAPPENING, MULTIPLE PARTS HAVE BEEN CHANGED. SEVERAL FORD ENGINEERS HAVE BEEN INVOLVED WITH NO RESOLUTION. THE TRUCK HAS BEEN AT THE DEALER FOR 7 MONTHS, PARKED FOR THE LAST 1 MONTH WITH NO ACTIVITY. I BELIEVE IT IS A SAFETY ISSUE, DUE TO THE FACT THE TRUCK WILL SURGE FORWARD ON ITS OWN. FORD NOW SAYS IT NOT A WARRANTY ISSUE, BUT WE STILL ARE UNDER THE 5 YR / 60,000 MILE POWER TRAIN WARRANTY. THIS IS A RECOGNIZED PROBLEM FOR MOUNTAIN SUPPLY AND SERVICE AND WE ARE TRYING TO RESOLVE IT BEFORE SOMEONE GETS HURT, AND WE FEEL THAT IT IS NOT OUR RESPONSIBILITY AT THIS POINT, SINCE WE HAVE BROUGHT IT TO FORD'S ATTENTION.

225V270000 · Back Over Prevention: Sensing System: Camera
Apr 23, 2025
Ford Motor Company (Ford) is recalling certain 2015 F-250, F-350, F-450, Expedition, Lincoln Navigator, and MKC vehicles. The rearview camera printed circuit board terminal header connector may be loose or damaged, which can result in a blank or distorted image.
Consequence & remedy
Consequence: A blank or distorted rearview camera image can reduce the driver's view of what is behind the vehicle, increasing the risk of a crash.
Remedy: Dealers will replace the rearview camera, free of charge. Owner notification letters were mailed October 16, 2025. Owners may contact Ford Customer Service at 1-866-436-7332. Ford's number for this recall is 25S42. This recall expands previous recall number 22V-082.
19V401000 · Equipment
May 29, 2019
VCI Emergency Vehicle Specialists (VCI) is recalling certain 2017-2018 Ford F-550, 2014 E-350 and E-450, 2015 F-250 and F-450, 2016 E-450, 2017 E-350, F-450 and E-450, 2018 F-350, 2010 E-450, 2005-2006 E-450, 2009 E-450 and Chevrolet C4500-based Type I and Type III ambulances equipped with ASA Electronics Voyager monitors used to display the back-up camera image. The monitors may unexpectedly revert back to the factory default settings which may cause the camera image to be reversed.
Consequence & remedy
Consequence: The driver may inadvertently turn the wrong direction to avoid an object behind the vehicle, increasing the risk of a crash.
Remedy: VCI Emergency Vehicle Specialists will work with ASA to notify the owners, and remedy the displays, free of charge. The recall began May 9, 2019. Owners may contact ASA Electronics at 1-800-384-4400.

1RQ14005 · Vehicle Commanded Engine Shutdown

Status: closed (inferred from source dates) · Electrical System:software; Engine; Engine And Engine Cooling:engine:diesel; Engine And Engine Cooling:exhaust System; Engine And Engine Cooling:exhaust System:emission Control
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.
