2015 Ford F-150 Electrical Problems

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 NHTSA 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 NHTSA 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.

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.

This is a supplemental complaint to my earlier report regarding NHTSA Campaign 26V237 / Ford Safety Recall 26S28. The recall remedy (PCM software update) was performed at W.C. Sanderson Ford in Healdsburg, CA on XXX. The original downshift defect recurred within weeks, including a near-miss where I nearly lost control of the vehicle with my [XXX] son inside. Since then, I have had the vehicle independently scanned twice, including a full all-systems diagnostic scan. The scan shows a communication fault (U0401, "Invalid Data Received From PCM") present across five separate control modules: ABS, Airbag/Occupant Classification System, Power Steering Control Module, Tire Pressure Monitoring/Body Control, and the engine module. The scan's own assessment recommends repairing CAN-BUS wiring and connections. I believe this network-wide wiring fault may be the actual underlying cause of the condition recall 26S28 was intended to fix — the recall's software update assumes a signal-loss problem can be resolved in software, but if the root cause is physical wiring, the remedy would not correct it. This would explain why the defect recurred so soon after the software update was installed. A second code, P2112 (Throttle Actuator Stuck Closed), also appeared spontaneously while the vehicle was parked. This code is documented in Ford's own Technical Service Bulletin 16-0139 (issued 2018), indicating Ford had prior knowledge of related fault patterns on this vehicle range. Of particular concern, the Airbag/Occupant Classification System is affected by the same communication fault. This system governs airbag deployment behavior based on occupant detection, and my son rides in this vehicle regularly. The vehicle is currently not safe to drive. I am requesting NHTSA evaluate whether the 26S28 remedy adequately addresses the underlying defect, given evidence that a wiring-level fault — not solely a software issue — may be the true root cause.

vehicle: 2015 Ford F-150 XLT, 5.0L V8, approximately 148,000 miles. I previously had the related recall/software update performed on this vehicle. On two separate occasions the transmission performed a sudden, uncommanded downshift while driving at highway speeds. On one of those occasions the rear tires locked up / skidded. There was no warning, no driver input, and no diagnostic trouble codes (DTCs) were stored or displayed. After these events, a Ford dealership inspected the transmission and found metal debris in the transmission pan. This is how the current transmission problem was discovered. My symptoms match the defect described in NHTSA recall 26V237 / Ford campaign 26S28 (and the prior investigation PE25002 / EA26001): intermittent loss of Transmission Range Sensor signal due to degradation of the molded lead frame, resulting in unintended downshifts that can cause rear-wheel lock-up. I am requesting that Ford review this case for coverage or goodwill assistance related to the known lead-frame defect and the subsequent internal transmission damage.

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

I was on the highway and my truck suddenly decreased speed rapidly. Luckily I was able to pull onto a side road and get to safety but it was extremely dangerous and scary situation. The dealer has confirmed the symptoms fit the issue with the recall. Since Ford does not have a fix for this solution yet until July 1 my vehicle is unable to be driven or repaired leaving me stranded without a vehicle. However, this is a very concerning safety issue and my family could have been severely impacted traveling on the highway.

The vehicle lost power rolling from a stop sign, felt like it was trying to shift but wouldn’t then went into limp mode, drove fine the next day. The faulty lead frame is failing, it has no other cause. I refuse to drive and put myself and others in danger to prove it. The dealer said they couldn’t cover it because the code is not covered in the recall, they recommended a new valve body or transmission, they didn't even say why. They were able to recreate it wrench light. P2704 is the code they claimed with the 2 leading causes are valve body, they said my fluid was clean and the vehicle has up to date service with no previous sign of wear, or the lead frame going out, the ACTIVELY recalled part. I tried contacting ford directly and they refused assistance beyond “tow it to a different dealer” and then ended the conversation. It is a safety issue that I will not wait to have break if there is clear signs of it happening.

My 2015 Ford F-150 experienced a sudden, dangerous loss of throttle power while driving, forcing an emergency stop on the side of the road. The vehicle is now locked in a hard electronic no-start/no-crank condition. We diagnosed the vehicle and pulled active, stored trouble codes P0706 and P0707 for the Transmission Range Sensor (TRS).This failure matches the exact defect described in NHTSA Campaign 26V237 / Ford Recall 26S28. However, Ford Corporate and the local dealership (Washington Ford in PA) are actively refusing to provide an emergency diagnostic scan, towing, or physical parts replacement, claiming they will not honor the remedy until June 30th. This has left a hazardous, disabled vehicle stranded on my property. They have acknowledged this meets the criteria of the safety recall but want me to pay for the towing of the disabled vehicle, diagnostics, and repair upfront including the lead frame which the recall notice specifically states should be replaced because the codes were thrown before reprogramming.

1. System Failed: Power Train (Transmission). Component Failed: The 6R80 6-speed automatic transmission, specifically the internal lead frame and the direct drum. Inspection: No, the failed unit was replaced on December 19, 2025, but itemized diagnostic reports and repair invoices from both a Ford dealer and an independent shop are available for inspection. 2. The vehicle experienced sudden, unexpected downshifting and a temporary loss of power while in motion. These incidents occurred frequently and randomly, particularly while accelerating or traversing inclines, creating "unsafe driving scenarios" where the vehicle could have been rear-ended or lost traction due to abrupt gear changes. Furthermore, the vehicle eventually entered "limp mode," where it would "buck" during shifts and fail to accelerate under load, leaving the driver vulnerable in traffic. 3. Yes, by both. Independent Center: Super Tech Automotive confirmed on December 11, 2025, that the transmission line pressure dropped from 158 psi to 20 psi under load, causing the vehicle to go into "limp mode". Dealer: South West Ford Service Department verified the concerns on December 16, 2025, documenting a "torque converter shudder" and "direct drum failure" with "excessive metal debris in fluid". 4. Yes. The vehicle was inspected by a manufacturer-authorized dealer, South West Ford Service Department, on December 16, 2025 (Service Advisor Ryan Forbis; Transmission Specialist 'Dietrich'). 5. Yes. Symptoms: The symptoms first appeared in August 2025 as a "sudden, temporary loss of power or unexpected down-shifting". Warning Lamps: Initially, no warning lights or error codes were produced, which prevented early detection during multiple diagnostic attempts. Later Symptoms: On December 11, 2025, the SES (Service Engine Soon) Light finally appeared when the truck entered "limp mode". Prior to the total failure, the transmission also exhibited "harsh/jerky downshifts" and would "hang up in gear".

Truck began reviving at high idle after throwing a check engine light, then wrench light as I was driving. I was able to safely get off the road. Shut it down wouldn't restart. I let it sit for 4 hrs, it started then I began driving again as there was no indication of an issue before. At 50mph it happened again. Truck began reviving at recline, check engine and wrench light. Shut it down again, and this process of restarting again hours later as nothing was wrong is still going on, 3 yrs of it. Check engine codes that do come up when it begins again all point to speed sensor and leadframe. Someone said check cam sensors but have no check engine on them at all, only leadframe issues that abruptly occur out the blue. When it happens I can driving at any speed and first thing that happens is the throttle revs to redline and Truck begins shifting abnormal, check engine, wrench, shutdown(thankfully), then hours again now indication of an issue! When i get the truck shut off and off the road, which i had it towed 7 times, show p705,706,707 codes all pertaining to leadframe. Please for the sake ny family and many others recall the 2015-2017 F150s for this $2000 electrical sensor replacement that is putting lives in jeopardy.
