When driving down the highway the vehicle downshifted abruptly and the engine started shuddering and shaking at a high speed. I was forced to pull over on the side of a busy highway in a 70mph section. A Ford dealership in the area inspected the issue and stated that the engine was blown after only ~150,000 miles. The transmission wrench and engine light came on prior to the incident but would turn off after a few minutes and both lights turns on during the incident. The circumstances described in Safety Recall Notice 26S28 / NHTSA Recall 26V237 occurred during the incident but a blown engine was not covered in this recall. However, the vehicle experienced an unexpected sudden downshift and then the engine malfunctioned.

I purchased my 2015 Ford F150 January 2020. I’ve had several issues with the brakes, calipers & rotors. From Sept 2022 my truck has been in the shop for these issues 6 times & it’s now doing the same thing. I’m [XXX] & have never had so many of the same issues with one vehicle. There has to be something causing this. Please tell me what I can do to keep from spending so much time & money on this. I greatly appreciate it.

Prior to this incident, the vehicle had no unusual noises, warning lights, or other indications of a drivetrain problem. On 06/18/2026, while driving under normal city driving conditions at approximately 45 mph, we suddenly began hearing a clunking noise coming from the vehicle. We did not know where the noise was coming from at the time, but because it was unusual and appeared to indicate a serious mechanical problem, we drove approximately three miles to our home. The vehicle was then transported on a trailer to a Ford dealership for inspection. The Ford dealership diagnosed a failure of the rear differential/rear axle assembly. According to the dealership's diagnosis, the rear differential bearings had failed, the ring and pinion gears were making noise and required replacement, and the driver-side carrier bearing had come apart, damaging the rear axle housing. The dealership recommended replacement of the rear axle housing and related differential components. I contacted Ford Motor Company and requested goodwill assistance regarding this failure. My request was documented under Case # CXH-08638079-H7C5F4; however, Ford denied the goodwill assistance request. I have photographs documenting the condition of the failed components and can provide those photographs if requested. I am concerned that a sudden failure of a major drivetrain component without prior warning could create a safety risk by causing a loss of vehicle mobility, unexpected vehicle behavior, or leaving occupants stranded in traffic or another unsafe location. I am submitting this complaint so NHTSA can document the failure and determine whether similar incidents have occurred with 2015 Ford F-150 vehicles.

The timing belt/chain is failing on F-150 trucks and multiple people have sent in issues. i think from 2015-2018. It looks like you are already looking at other Fords with same issue. what i was told is that there could be sudden stalling: If the timing is thrown off or the chain snaps, the engine cuts out instantly. Losing power steering and engine power while driving in traffic creates an immediate crash hazard. Severe Misfires and Power Loss: A slipping chain causes rough idling, violent shaking, and an inability to accelerate which happened to the truck. Due to this i had to get mine fixed in June of 2024 i have attached the invoices. I tried to upload invoice but said there was an error

While removing child care seats from the back-right passenger seat, I noticed an unusually loud tingling sound from the lower anchor point of the seat belt. Upon inspecting it, I noticed that the bolt anchoring the bottom part of the seat belt was completely unscrewed and was only being held on by the tension of the seat belt. Once unbuckeled, the bottom anchor of the seat belt came out completely. There were no special circumstances to cause the seat belt bottom anchor to come unscrewed beyond normal use. Component is available for inspection upon request. The issue has not been brought to the attention of the dealer or manufacturer. The vehicle has not been inspected by anyone other than the owner. The unscrewing of a bolt that is critical to the proper function of a seat bealt through normal use and without any indicators or warnings creates serious unsafe conditions that could result in harm to oneself or others.

My vehicle experiences total loss of the instrument cluster PRNDL gear display, an active Wrench Light, and unexpected shifts into Limp-Home Mode while driving in traffic, creating a severe crash hazard from trailing vehicles. An OBD-II scan confirmed permanent fault codes P0715 (Input/Turbine Speed Sensor Circuit Malfunction) and P0717 (Input/Turbine Speed Sensor No Signal). West Herr Ford of Amherst (NY) inspected the vehicle on July 25, 2026. REASON FOR COMPLAINT / REMEDY INADEQUACY: #1 Software vs. Hardware: Recall 26S28 uses a PCM software reflash to alter computer logic during signal drops. This software reflash does NOT fix the underlying physical breakdown of the 6R80 molded lead frame assembly. Thermal cycling and vibration continue to degrade internal wiring, causing active driving failures after the recall update. #2 Omission of Known Codes (P0715/P0717): The Turbine Speed Sensor (TSS) and Output Speed Sensor (OSS) are physically integrated inside the EXACT same plastic molded lead frame. However, dealers refuse to cover part replacement under 26S28 for P0715/P0717 because they are omitted from the recall's automated approval list, forcing out-of-pocket costs exceeding $1,200 for a known manufacturing defect. REQUESTED ACTION: I request NHTSA require Ford to expand 26S28 hardware replacement authorization to explicitly include lead-frame-integrated codes P0715 and P0717, and mandate physical lead frame replacements for all vehicles exhibiting active sensor circuit failures.

Ford issued 4 codes for campaign #26S28 (PCM recall). Numerous owners are being denied warranty/safety repairs due to “other codes” appearing after computer update. Same limp mode, same sudden downshifting and will cost us (and many others) thousands in repairs because Ford put out faulty repairs. We will be paying 1800 for 2 codes NOT included but for a part that is integrated with the lead frame. MANY others are documenting similar circumstances online. My 16 yr old child will be driving this vehicle. I have filed numerous complaints under my case number with Ford should their “cheapest fix” cause additional issues.

I am submitting this complaint regarding Ford Recall 26S28 (NHTSA Recall 26V237). My truck exhibited the dangerous unintended downshift condition described in this recall for several weeks before the repair remedy became available. A few weeks weeks before April 27, 2026, the truck began unexpectedly downshifting from approximately 5th or 6th gear into a much lower gear while driving. Each event caused the truck to enter limp mode, illuminate the wrench light, display multiple warning lights, and shake violently. I had to pull off the road, shut the truck off, wait several minutes, and restart it before it would drive normally again. I immediately reported these incidents to Mike White Ford and was repeatedly told to monitor the vehicle because no recall remedy was available. I reported the issue again during an oil change on April 27, 2026. Driving home from that appointment (9 miles), the truck experienced two more unintended downshifts. We immediately called the dealership and were again told to continue monitoring it. The condition progressively worsened over the next several weeks. On May 31, 2026, the truck experienced six unintended downshifts in one day. After the final event, it became difficult to restart and the check engine light illuminated. By my June 8 appointment, the truck was stuck in permanent limp mode and had to be towed to the dealership. The service manager stated it was "unsafe to drive" and provided a loaner vehicle. The truck later stored DTC P0219 (Engine Overspeed) and P2112 (Throttle Actuator Control System-Stuck Closed). I estimate the unintended downshift occurred approximately 75 times before the truck became inoperable. I opened Ford case CXH08666656S0W4Q2 on July 21, 2026. I respectfully request that NHTSA review whether prolonged operation with this known recall condition, while owners awaited a repair remedy, may contribute to additional vehicle failures and increased safety risks.

Vehicle suffered a violent, un-commanded highway-speed downshift due to NHTSA Campaign 26V237000 / Ford Recall 26S28. The tachometer was redlined during the incident. The mechanical overspeed immediately damaged the engine's cam phasers. Eide Ford in Mandan, ND, applied the recall software patch after the structural failure already occurred, cleared the diagnostic trouble codes without providing a copy to the owner, and is refusing to replace the lead frame or cover the resulting valve train damage, demanding $7,200 out-of-pocket.
