My vehicle (2015 F-150) has the recall for Powertrain control module pcm reprogramming. Truck recall has no solution yet. The truck can downshift to 2nd gear at highway speeds. This is a known issue and ford is working on fixing it. I am submitting a complaint because I am worried about safety and catastrophic engine failure if this issue continues.
i went to lombard Ford in [XXX] on XXX because my vehicle was downshifting hard and asked them to make the repair. They said that ford was anticipating a recall but that I coud have them reprogram my vehicle in accordance with TSB 16-0015 and submit my reimbursement to [XXX], In XXX ford send me a letter stating a remedy was available. to address the situation.

I took my truck to the dealership for them to fix the transmission recall. Afterwards it started shifting funny and was not normal like before, I started getting codes like P0721 I took it back and they said it had nothing to do with what they did. I don't believe that - the truck was fine before. They finally looked at it again and said the recall had been stopped and they could do nothing anymore until it was reinstated. They also said I need a new transmission now. This is pissing me off.

I am writing on behalf of my father, [XXX], age [XXX], regarding his 2015 Ford F-150 (VIN [XXX]), which is covered by Safety Recall 26S28 for unintended transmission downshift. His truck has already experienced the defect. In early October, it unexpectedly downshifted while he was driving. He contacted Asheville Ford multiple times to schedule a service and has been told the recall has been paused. His request for a loaner or rental was declined. Ford's recall page describes this defect as one that can cause the rear wheels to slide or lock up and increase the risk of a crash. Ford's site now also instructs owners not to have the repair performed while Ford investigates problems with the software remedy. As a result, the truck has a confirmed safety defect that Ford is not currently able to repair. This truck is my father's only transportation. He cannot safely drive it, and Ford has not provided a timeline for a repair. We are asking Ford to provide a loaner or rental vehicle until the recall repair can be completed. We believe this is a reasonable request given that the vehicle is unsafe because of a defect Ford has acknowledged, and the delay in repair is due to Ford's own investigation. Thank you for your help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2015 Ford F-150. The contact received notification of NHTSA Campaign Number: 26V237000 (Powertrain), and the recall repair was completed. The contact stated that after the recall repair was performed, the vehicle experienced transmission downshifting at high speeds and hesitation. The contact also received notification for Customer Satisfaction Program: 26N04 (Transmission Molded Leadframe Replacement). The contact stated that the failure initially occurred when an orange wrench icon illuminated on the instrument panel. The vehicle was taken to the dealer; however, the dealer refused to perform the program repair at no cost. The dealer stated that the failure originated within the output speed sensor located inside the molded leadframe and required the contact to pay for the repair out of pocket. The dealer stated that the component would not be replaced under the program because the vehicle did not display the specific Diagnostic Trouble Code (DTC) required for coverage. The contact stated that the code was absent because the dealer completed the Powertrain Control Module (PCM) software update, erasing all stored Diagnostic Trouble Codes. Both the manufacturer and the dealer were notified of the failure. The failure mileage was 105,000.
The contact owns a 2015 Ford F-150. The contact stated that while driving at 70 MPH, the vehicle downshifted from sixth to fifth gear. The contact associated the failure with NHTSA Campaign Number: 24V444000 (Power Train). The dealer was notified of the failure; however, the contact was informed the part for the remedy remained unavailable. The failure mileage was 100,000.
The contact owns a 2015 Ford F-150. The contact stated that while driving at approximately 60 MPH, the vehicle unexpectedly downshifted into first gear, causing the engine RPM to increase. The wrench warning light illuminated, and the Drive (D) and Reverse (R) indicator lights turned off. The vehicle failed to restart and required towing on two occasions. The contact expressed concern that the unexpected downshift and potential rear-wheel lockup could result in a loss of vehicle control and a crash. The contact associated the failure with NHTSA Campaign Number: 26V237000 (Power Train). The manufacturer was notified and advised that the recall was paused, offering no further assistance. The dealer was notified of the failure. The failure mileage was approximately 153,000.
The contact owns a 2015 Ford F-150. The contact stated that while driving at various speeds, the transmission would downshift to first gear as both the traction control and check engine warning lights would appear on the instrument panel. The contact used purchased a scanner which gave him a code for P0720(Output Shaft Speed Sensor Circuit). Upon investigation, the contact discovered that the vehicle was under recall for NHTSA Campaign Number: 26V237000(Power Train). The contact called two separate dealers where he was informed by both that the manufacturer had placed a pause on the recall remedy after they discovered that the software remedy did not repair the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 182,000.
I had recall 26S28 performed on my 2015 Ford F150. The intent of the recall is to prevent the transmission from unexpectedly shifting into second gear while at highway speed. Immediately after the recall service was performed, the transmission will fail to shift into low gear after coming to a stop before the vehicle is fully warmed up. Pulling away from a stop is very slow (transmission is in a high gear). This creates a traffic safety hazard if there is traffic approaching at an intersection or while merging into traffic. Other vehicles have to brake to avoid me. The servicing dealer has reproduced this problem, but Ford is unwilling to remedy it. There is an orange wrench symbol on the dashboard when this happens. The transmission performed normally under all conditions before this recall service was performed.
Vehicle had mechanical failure in the transmission at 70 mph. The PCM shifted my transmission in to 1st gear and locked up my rear tires at 70pm, which is covered under NHTSA 26V237000. Ford has an open recall: 26S28 for a software update, which is currently paused. They also have 26N04 to replace to failing lead frame within the transmission. Ford is refusing to repair the vehicle under 26N04 (hardware) while 26S28 (software) is paused, which are two separate issues. A software pause should NOT invalidate a physical component failure that is explicitly covered under an active safety mandate.
The contact owns a 2015 Ford F-150. The contact stated that while driving at 35 MPH, the transmission downshifted independently. The failure was persistent. The vehicle was taken to two independent mechanics, both of whom advised the contact to take the vehicle to the dealer. The dealer was notified of the failure by phone and informed the contact that parts were unavailable. The contact received a recall notification for NHTSA Campaign Number: 26V237000 (Power Train); however, the parts to complete the repair were unavailable. The failure mileage was approximately 102,500.
2015 Ford F-150 Platinum, 6-speed automatic. Ford recall 26S28 (NHTSA campaign 26V-237, PCM software update for unintended transmission downshift) was performed at All Star Ford, [XXX]. BEFORE the recall service, this truck ran smoothly, quietly, and flawlessly. AFTER the PCM update, the transmission developed severe jerking and hard downshifting that never existed before the recall work. The dealership has held my vehicle since XXX. The mandatory post-update reset drive was skipped after the first update; the recall has since been re-performed twice and the malfunction persists - it was directly caused by the recall calibration. On XXX, the general manager stated the vehicle was "safe to drive" yet admitted he could not guarantee no further operational or safety issues would occur, and confirmed Ford engineers currently have no fix. I was also told Ford halted work because this recall update damaged my vehicle and thousands of others. I have been without my vehicle since May 2026. The recall remedy has rendered my vehicle unsafe to drive. I am filing so NHTSA is aware the 26S28 remedy is producing new transmission malfunctions.

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 / NHTSA 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
