2014 Ford F-150: engine stalls while driving

Filed Sep 14, 2026 · Transmission · MN

Ford did recall on transmission, it failed on my way home. I took it back and they refuse to fix trying to separate event to warranty issue. 3weeks later I have no truck and being stalled by ford. Even Elena Ford has it on her desk(computer) 4 days no response. They quickly processed the recall so they can imply it never had one. Lead module(connector) is reason and part of recall.

My 2014 Ford F-150 is exhibiting symptoms consistent with the Ford transmission molded lead frame safety recall 24S37. While driving approximately 55 mph late at night on a five-lane roadway, the vehicle suddenly and violently jerked, downshifted and came to a complete stop becoming stalled out as I was approaching a major traffic intersection. The truck was disabled in traffic and would not restart for approximately 2-3 minutes, leaving me stranded in an active travel lane and at risk of being struck from behind by another vehicle at high speed. The vehicle has displayed transmission-related symptoms including inability to correctly indicate gear position, harsh shifting, unexpected downshifts into 1st gear while driving, transmission fault warnings, and check engine lights. Initially it was mostly dying while idling and we thought it was the common "Fuse 27" issue, being unaware of the recall. Then the condition reproduced multiple times and symptoms worsened dramatically. Ford dealership inspected the vehicle. According to the technician's written report, the truck was found to be "having transmission problems, unable see what gear the truck is in and shifts to 1st gear while driving" and recommended replacement of the molded lead frame. The dealership confirmed transmission-related diagnostic trouble codes were present and documented symptoms consistent with lead frame failure. Despite the recommendation of the lead frame replacement and documenting symptoms consistent with the safety recall, the repair was not approved. The vehicle continues to experience symptoms associated with the recalled defect and is unsafe to drive away. Dealership confirms software update will not correct problem. I am submitting this complaint as the transmission defect poses a significant safety hazard to me, my children, and other drivers due to unexpected downshifts, loss of power, stalling, and the risk of becoming disabled in traffic. The truck remains available to inspect

Complaint Description: Unintended Transmission Downshift Vehicle: 2014 Ford F-150 Issue: Intermittent Transmission Malfunction / Severe Unintended Downshifting Detailed Symptoms: Sudden Downshifting: While traveling at cruising speeds (typically in 4th or 5th gear), the vehicle occasionally performs an uncommanded downshift directly into 1st gear without driver input. Start-up Stalling: The vehicle intermittently becomes "stuck" in 1st gear upon acceleration from a stop, refusing to upshift into higher gears. Lack of Warning: These events occur with zero warning signs. No "Check Engine" light, "Wrench" icon, or transmission temperature warnings appear on the dashboard before, during, or after the incident. Recall History: The vehicle previously received the official Ford recall repair for the Lead Frame/Output Speed Sensor issue, yet the life-threatening symptoms have persisted or returned. Diagnostic History: The vehicle has been inspected by an authorized Ford dealership on two separate occasions. The technicians reported that they were "unable to duplicate the failure" and found no stored error codes, leaving the safety defect unresolved. Safety Concern: I am filing this complaint because the sudden shift to 1st gear at high speeds causes a violent deceleration (similar to slamming on the brakes), which risks a loss of vehicle control or a high-speed rear-end collision. I have raised this issue to Ford customer relation department as well. Case# CXH07719550, Date: 04/20/2026

Reference Tracking # 11622306. I purchased my used F150 with 52,956 miles on 1/3/2020. Shortly after, I would occasionally notice an unusual gear downshift. Upon receiving Ford Recall 24S37 (the federal safety agency 24V444000) update for the powertrain control module, the check engine lite (CEL) came on. I called the Ford Recall ph#, and they told me to continue to work with the dealership that performed the update. Several times I returned to the dealership, they would reset it with diagnostics, yet repeatedly the P0299 code would return each time. Prior to the CEL coming on, the CEL was preceded by a stall on acceleration on small hill inclines, and worsened fuel mileage, and typically after towing my trailer. These things didn't occur before the update was installed. (Attachments)

I was on the recall list and got my OSS sensor reprogrammed at a Ford dealership in August of 2024. November 6, 2024 I was driving down the FRWY at 65 miles an hour. There was a jolt and RPMS dropped to zero, speedometer dropped to zero yet truck was still traveling at a high rate of speed. My info area just gave blank dashes. It was like the things on my dashboard just stopped registering, and eventually a wrench flashed across the screen. My gas pedal was not responding, and I could not accelerate when I pressed the gas. Luckily I was able to coast off of the FRWY with emerg. flashers on without accident. I had to stop at a red light on service road and after stopping truck did not accelerate at light. I turned off the engine and restarted and was able to slowly accelerate at slow speed to make it home. The next morning I took the truck straight to the dealership (maxing at about 20mph- gas just wasn't accelerating like normal) and was told it needed replacement of the transmission electrical frame. I told them about the recall that I recently had reprogramed (august to November 6). The dealership claimed that the recall update and the transmission electrical frame failure was unrelated. They claimed that the transmission electrical frames commonly went out on these trucks and were a known problem but it hasn't been enough to produce a recall. I had to pay about 2k to get my truck fixed. The dealership said if there ever was a recall then I would be reimbursed for the part. What happened to me on that freeway of not being able to accelerate at all was very dangerous as I could not accelerate at all. It was not safe for me to continue on the freeway (or any road really) as my vehicle basically stalled out on me while driving and would not go at all until restarted. I'm very grateful that I was able to get out of that situation safely.
