While driving my 2015 Ford F-150, the vehicle experiences a severe and hazardous transmission defect. The transmission unexpectedly drops out of gear while in motion, resulting in an immediate loss of power and acceleration. Simultaneously, the 'D' (Drive) gear indicator light on the instrument cluster goes dark, and both the wrench warning light and check engine light illuminate, forcing the vehicle into an unsafe limp mode. This vehicle is subject to active safety Recall 26S28 / the federal safety agency 26V237 regarding unintended transmission downshifts and Transmission Range Sensor signal loss. I contacted an authorized Ford dealership to have this federally mandated safety recall performed. However, the service department explicitly refused to execute the recall repair, stating that the recall procedure does not solve the problem and makes it worse. The dealership is refusing to perform the required safety service, leaving my vehicle unrepaired and creating a dangerous ongoing safety hazard on public roads

While driving my 2015 F-150 in live traffic, the vehicle suffered an abrupt, catastrophic powertrain and electronic control module failure, resulting in an immediate engine stall and severe traffic hazard. Multiple cluster warnings (Check Engine, Cross Traffic, Hill Assist) illuminated, followed by a total mechanical shutdown into a permanent "No Start" condition. The truck was towed to a Ford dealership.The diagnosis by the certified Ford technician (Repair Order #5804) confirms the root cause mirrors the exact hardware defect covered under Ford Recall 26S / the federal safety agency Campaign 26V237000. The transmission internal molded lead frame and Transmission Range (TR) Sensor suffered a severe electrical short circuit due to thermal degradation in the fluid.Crucially, this failure triggered a sudden, uncommanded downshift that forced the transmission into 2nd gear at driving speed. This created a violent rotational speed shock that physically shattered the internal planetary gears and clutches. This severe mechanical explosion left the "EXCESSIVE METAL" found in the oil pan, completely destroying the transmission internals.Simultaneously, the internal short circuit back-fed destructive voltage directly into the PCM reference circuit, immediately blowing the 10-amp main power supply circuit (Fuse F93). Because the shorted PCM completely killed module communication ("NO COMMUNICATION WITH PCM"), the computer was physically incapable of saving diagnostic trouble codes (DTCs) prior to replacement. The "TRANS TR SENSOR CODES" only surfaced once a new PCM was installed to restore communication. Ford is wrongfully denying my $8,581.23 recall reimbursement of my transmission and pcm solely because the defect itself completely destroyed the computer’s ability to log data before repairs began.

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.

I am reporting a potentially serious safety issue involving my 2015 Ford F-150 Lariat 2.7L EcoBoost (129,610 miles at recall service; now approximately 130,155). On XXX, Orchid Isle Ford in [XXX] performed recalls 24E03 and 26S28 (Service Order XXX). Before this recall service, I had never experienced the engine-stalling problem described below.Since the recall work, my truck has unexpectedly shut off more than six times. While slowing for a traffic light, the RPM smoothly drops and the engine quietly shuts off. I do not have to be completely stopped. I must put the transmission in Park and restart the truck, after which it generally operates normally. The truck also intermittently takes longer than normal to start. No check-engine light appears when it stalls.There was also a previous frightening incident on Saddle [XXX] before the recall service. While transporting a truck full of girls to a volleyball game, the truck unexpectedly and rapidly downshifted. A wrench warning briefly appeared. We turned the truck off and restarted it, and the warning disappeared. Recall 26S28 is relevant because it addresses an intermittent Transmission Range Sensor signal to the PCM that can cause unintended downshifting. I returned the truck to Orchid Isle Ford on XXX. They could not reproduce the stall during an 8-mile test drive and found no active codes. Their testing found fuel-pump pressure/injector readings, battery, and compression were normal. The vehicle continues to stall.The battery was recently replaced and the fuel pump was replaced XXX.I cannot establish that the recall programming caused the stalling, but the timing is concerning. I have also found reports from other 2.7L EcoBoost owners describing low idle/near-stalling after PCM updates, including reports associated with 24E03.I request that the federal safety agency investigate whether PCM programming, 24E03/26S28, Transmission Range Sensor/PCM communication, or related powertrain issues could cause shut INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.

The technician from the local Ford dealership came out to fix the federal safety agency recall 26V237 on 8/7/26. The fix for this was to reprogram the Powertrain Control Module software. My husband got into his truck 3 days later, (8/10/26), and after driving half a mile the check engine light came on and the truck began to drive rough. He immediately took the truck to our local mechanic, (not at the Ford dealership). The next day we were told the PCM was fried and we would need to tow the truck to the Ford dealership for the fix. My husband explained the situation and they denied culpability. The truck had never had any computer, or computer related issues, until the PCM was "reprogrammed".
