2015 Ford F-150 electrical problems

Filed Oct 6, 2026 · Electrical, Transmission · UT

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

The contact owns a 2015 Ford F-150. The contact received the federal safety agency Campaign Number: 26V237000 (Power Train). Ford Campbell sent a technician to the residence on August 9, 2026, to perform the update. While driving, the power train warning light was displayed. The technician arrived at the residence again to repair the vehicle. There was lag while driving, and the transmission unexpectedly downshifted. While driving 25 MPH, the power train warning light was displayed. The vehicle was taken to another local dealer, Ted Russell Ford Kingston Pike (8551 Kingston Pike Knoxville, TN 37919); and the vehicle was towed to be diagnosed. The contact was informed that the software needed to be updated on several occasions. The contact was informed that the fuel pump, electrical system, and battery needed to be repaired. The dealer determined that the power control module needed to be replaced. The contact stated that installing and removing the software had caused the failure, and the technician was unable to repair the vehicle. The manufacturer was contacted by phone.

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.

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 the federal safety agency 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 the federal safety agency 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 the federal safety agency 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
