On 9/25/2026, I made an appointment with a Ford Dealer to receive a fix for the federal safety agency saftey recall 26V237 on 10/7/2026. Before 10/7/2026 Ford paused the recall. In their own notice Ford says this problem could result in loss vehicle control increasing the risk of a crash. They do not rule out that a crash could occur at high speed. It appears that before the pause, they applied a software fix to many vehicles which caused new problems. They should make a serious effort to effect a solution even if it requires replacing hardware.

Just over a month ago, I had my local dealership's mobile service come to perform the covered warranty reset on the powertrain module. Last week, while driving apx 40mph, vehicle went into what I now know was "limp mode" 3 times within a few minute span -- felt like vehicle shifted into neutral, wrench light came on, but did not stay on for more than a few seconds. Had a diagnostic appointment yesterday, and was informed that the molded leadframe and oss sensor need replaced, at a cost of over $1600, including the $233 I paid for diagnostics. Today I found my letter from July regarding Customer Satisfaction Program 26N04. Everything in the letter matches my vehicle's issues, but I am being told by Ford that because my vehicle is not displaying the "correct" code per the service bulletin, it is not eligible for free warranty repair. How is it not eligible? This is a confirmed problem with the entire part, but they don't want to fork over the money to repair a cheaply made component, so they are offering bandage fixes, and paring down the eligibility criteria so narrowly that nobody qualifies to have the problem addressed. This seems predatory and negligent.

I am writing to formally report a dangerous safety defect involving my 2015 Ford F-150 XLT SuperCrew Cab. While operating the vehicle, I experienced a sudden and total loss of control. Without warning, the gas pedal lost all tension, the truck abruptly downshifted and went into limp mode, and both the check engine and wrench warning lights illuminated on the dashboard. This loss of control while driving created an immediate and severe safety hazard. My investigation into this failure reveals a widespread pattern of similar incidents involving the transmission molded leadframe. It appears that the failure of this component frequently causes an output shaft speed sensor malfunction, leading to the exact dangerous loss of power I experienced Given the high frequency of these reports from other owners. This loss of control while driving created an immediate and severe safety hazard. Upon experiencing these symptoms, I promptly scheduled an appointment at my local Ford dealership. Despite the service department confirming that the transmission lead frame is failing, Ford refused to perform the repair citing that my specific trouble codes are not currently approved under their policy. This is unacceptable, as these symptoms are identical to those addressed in recall 26S28 and Ford has previously acknowledged that these specific codes are directlv related to this component's failure in other mode years. My investigation into this failure reveals a widespread pattern of similar incidents involving the transmission molded leadframe Given that my vehicle exhibits all the symptoms described in the existing recall, it is clear that this is a systemic manufacturing defect that Ford is failing to adequately address. I request that the federal safety agency investigate this issue and Ford's restrictive repair criteria, as this defect poses a significant risk to myself and the public on the road.

My 2015 Ford F-150 experienced multiple sudden downshifts at highway speeds 75 mph and then started downshifting at lower speeds. Heavy clunking heard and wrench warning lamp came on with a very general warning message and turned both off after moving to the side of the highway and restarting the car. Warning sign returned while driving at significantly lower speeds on city streets, locked up tires when turning from a low speed twice. Extremely unsafe and could have caused a serious accident if people were following close behind me. Took it to the dealership to get repaired and they diagnosed DTC P0722 (Output Shaft Speed Sensor - No Signal) and confirmed that the signal failure caused the transmission to lock in 3rd gear and operate at maximum line pressure. Technician notes it resulted in damage to forward, direct, and overdrive clutches and recommended the replacement of the entire transmission ($5,739 for parts). I paid $8,636.93 out-of-pocket at a Ford dealership for this service repair.

FORD CORPORATE CASE NUMBER: CXH-09262770. My 2015 Ford F-150 has experienced sudden, dangerous transmission downshifts at highway speeds that nearly caused a fatal collision. I complied with Ford's mandatory Recall 26S28 software flash, but the dangerous hardware symptoms remain active. The vehicle is currently grounded and unsafe to drive at the dealership lot, but Ford Corporate is denying the physical lead frame replacement due to narrow diagnostic code restrictions."

Execution of manufacturer safety recall service resulted in immediate, catastrophic transmission malfunction and sudden loss of motive power upon leaving the franchised dealership, creating an imminent road hazard. Details of the Incident: Recall Intake: On XXX, the vehicle was driven into the authorized Ford dealership Cloninger Ford of Morganton in [XXX] under its own power for an open manufacturer safety recall involving the transmission molded leadframe and PCM software update to prevent sudden, unintended downshifts. Immediate Failure Post-Service: After technicians completed the recall service and returned the keys, the vehicle was driven out of the dealership lot. Upon reaching normal road speed and shifting from 3rd to 4th gear (less than 0.2 miles from the service bay), the transmission violently malfunctioned, lost forward drive engagement, and rendered the truck completely disabled and undrivable in active traffic. No road test was performed by the dealership prior to releasing the vehicle. Safety Risk: The sudden failure and inability to shift gears properly left the vehicle stranded in roadway traffic, presenting an immediate collision risk. The vehicle had to be limped back into the dealership service drive immediately. Remedy Failure & Denial: The dealership acknowledged that the recall-mandated PCM software calibration update triggered the severe transmission failure. However, both the manufacturer and the dealer are now claiming the failure is a "pre-existing condition," refusing to complete the safety remedy without charging the owner $7,000 for a full transmission replacement. The safety defect that prompted the recall was not remedied and was instead exacerbated to total mechanical failure during execution of the recall procedure.

My local Ford Dealer (Tallahassee Ford) which I had just purchased the vehicle from two weeks prior. Refused to repair the federal safety agency Recall Number26V237 they wanted to charge me over 2000 dollars to fix even though it has a recall.
