On May 10, 2026, my 2016 Ford F-150 (6R80 transmission) went into limp mode and displayed a wrench warning light while driving. The truck lost normal transmission function and would not shift properly, creating a hazardous situation in traffic. The PCM has stored active Output Shaft Speed sensor codes P0720 and P0722, confirmed by a Paul Miller Ford IDS diagnostic scan, indicating a failing molded leadframe inside the transmission. When the OSS signal drops out at road speed, the PCM can command a sudden unintended downshift into a low gear, causing abrupt deceleration and potential rear-wheel lockup and loss of control — a serious safety hazard. Ford Recall 26S28 (26V-237) / Program 26N04 for 2015–2017 F-150s only covers a PCM software recalibration for the Transmission Range Sensor codes (P0705/P0706). It does not replace the leadframe hardware for the OSS codes (P0720/P0722) my truck is actually throwing. Ford's system auto-rejected the claim, and a dealer SSSC prior-approval request was denied. I am being told to pay out of pocket for a known defective part. For 2014 trucks, Ford replaced this same leadframe for free under Recall 24S37 when P0720/P0722 were present. My 2016 has the same transmission, same part, and same failure, but the current recall remedy is software only. I'm filing so NHTSA has documentation that the OSS leadframe failure is occurring on 2015–2017 F-150s and to request the remedy be expanded to cover leadframe replacement. No crash or injury occurred; the defect was confirmed by a Ford dealer.

Ford recently did a software update for a unexpected downshift recall that had previously happened to me while doing 60 miles an hour in my vehicle downshifted into first gear in my truck went sideways because the rear end locked up. Drove my vehicle home and took it out today and while doing 45 miles an hour it downshifted into first gear locking up the rear wheels again. Thankfully, this was at a lower speed so I was able to control the vehicle easily.. the turnpike speed limit in Maine is 70 miles an hour so if this happened at that speed in traffic, I’m almost positive there could have been a serious accident. So their update did not fix this issue.

The contact owns a 2016 Ford F-150. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted. The contact stated that the power train warning light and several other unknown warning lights were illuminated. The contact was notified that the VIN was included in NHTSA Campaign Number: 26V237000 (Power Train). The vehicle was taken to a dealer where it was diagnosed; however, the diagnostic result was unknown. The vehicle was repaired; however, the failure persisted, and the warning lights were flashing. The vehicle was taken to an independent mechanic where it was diagnosed and determined that an unknown transmission part and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

The contact owns a 2016 Ford F-150. The contact stated that while driving at various speeds, the transmission unexpectedly downshifted and became stuck in a lower gear before shifting into the intended gear. The powertrain warning light was intermittently illuminated. The vehicle was taken to the dealer, where DTC: P0705, P0706, P0707, and P1702 were retrieved, indicating a powertrain control module (PCM) and leadframe failure. The vehicle was not repaired because the warranty had expired the day prior. The contact later received notification of NHTSA Campaign Number: 26V237000 (Power Train), and the vehicle was taken to the dealer, where the PCM software update was completed. The contact was advised to drive the vehicle for an extended period and return to the dealer to determine if the leadframe needed to be replaced. The failure persisted while driving, and upon returning to the dealer, DTC: P0717 and P0715 were retrieved. The dealer submitted a claim to the manufacturer, but coverage for the leadframe replacement was denied because the diagnostic trouble codes did not match the recall specifications. The contact stated that the PCM software update erased the initial diagnostic trouble codes, preventing the leadframe replacement under the recall. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure mileage was approximately 81,000.

I went to start my truck and the brake went all the way to the floor. I had no braking power and it had to be towed back home over an hour away. There is a recall on 2016 Ford F150 with the 3.5 Eco Boost engine which I have. This recall involves a seal in the master cylinder failing and losing braking power and affecting the brake booster. Referencing recall 20S31. I went to Ford and they told me the recall did not apply to this specific truck due to a different batch of parts. This truck is now having the exact problem as the specific ones which have already been recalled. I believe the recall should be expanded. This occurred shortly after driving an hour in the rain with my kid in the back. It could have easily killed us on the highway with no brakes. We had no idea this recall was in effect. It’s the last time I’m buying a Ford. I want to feel safe with my kids in the back and Ford does not seem to care.

On XXX I lost all brakes in my 2016 Ford F-150 while towing a fishing boat. I had just decended a steep grade on a busy downtown street when I received an alert that I was low on brake fluid. The next pump of the brake went to the floor. I received an audible alarm. Had this occured on the steep grade, this could have been a very serious accident. I understand the loss of brakes was due to failure of the master cylinder just and as described by the open recall on my vehicle. I added a quart of brake fluid to an empty resevoir, tried to pump the brakes up and the fluid vanished. I could not find any evidence of a leak. Clearly the fluid is in the brake booster, which is also replaced under this recall. I had the vehicle delivered to the closest dealership, Pierre Ford of [XXX] on Monday the XXX. The service advisor tod me he would need ot for two days. Four days later, the advisor text me to report that parts are not available, and that he would let me know when they were. I asked him to make sure that a VOR report had been submitted so that my repair repair parts could be expidited by Ford Corporate. He assured me the VOR had been placed. Today, on XXX, I called Customer Care who verified my recall eligability, and also informed me that no VOR had been requested against my VIN. I have found genuine ford parts for the repair of my vehicle in many Ford facilities in the nation. I dont feel that Ford is working very hard to get my only vehicle back on the road INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
