2015 Ford F-150: engine stalls while driving

Filed Sep 25, 2026 · Electrical, Transmission · AZ

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 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.

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 traveling down the highway and merging onto the interstate, if you excelerate just the slightest bit, the truck will start to violently shake and not gain speed,almost stalls a bit,causing a dangerous situation if you're trying to merge into moving traffic.Through reading and my own research on various forums. This is called transmission stutter and is a common problem with Ford's 6 speed automatic transmissions, that is not specific to vehicle or trim level or year model.
