2014 Ford F-150: sudden loss of power

Filed Sep 22, 2026 · Electrical, Transmission · AL

I was driving up the Interstate I565 heading towards Decatur Al from Huntsville Al. I was cruising at about 80 mph. All of a sudden my trucks transmission downshifted into first gear causing my back end to fish tail and the RPM's maxed out in the red and the engine lost all power. After that it would not start and I had it towed to the Ford Dealership. They did nothing and they charged me. They went ahead and took care of the recall then: because an intermittent loss of signal from the output shaft speed (OSS) sensor / internal lead frame can cause an unexpected downshift to first gear regardless of vehicle speed. Recall DetailsPrimary/Initial Recall: Campaign 24S37 (the federal safety agency 24V444) in June/July 2024, covering over 550,000 U.S. vehicles (approx. 668,000 globally).Follow-up / Re-repair Recall: Campaign 26S45 (the federal safety agency 26V378) issued mid-2026 for roughly 44,963 vehicles where the prior PCM software fix was improperly applied or missed.Affected Vehicles: Select 2014 Ford F-150 trucks built at Dearborn and Kansas City plants (built mid-2013 through late 2014) What Happens & Safety RiskSymptom: Sudden, unintended drop to first gear, potentially causing rear-wheel lock-up, skidding, or a sudden reduction in vehicle speed.

Hello, I recently brought my 2014 Ford F-150 (VIN: [XXX]) to the dealership regarding Recall 24S37. The vehicle experienced the following symptoms: • Check Engine Light illuminated. • Wrench Light illuminated. • Intermittent loss of power. • Abnormal transmission behavior. • Intermittent no-start condition. • Vehicle would only start after moving the gear selector. The dealership informed me that no physical repairs would be performed because the diagnostic trouble codes retrieved were different from those associated with Recall 24S37. However, the vehicle continues to exhibit transmission-related symptoms, and I am concerned that the underlying condition may be related to or aggravated by the conditions addressed in Recall 24S37. I am requesting that Ford review this case and determine whether additional diagnostic evaluation or repairs should be considered. However, they refuse to accept that the codes have anything to do with the recall, even though it is the same part and the affected sensor that is triggering the error codes on the scanner. They are asking me to pay for the transmission repair because the codes are not the ones approved for the recall, but based on the signs and symptoms the truck is showing, it is a chain reaction that triggered the previously mentioned failures. Thank you INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

My 2014 Ford F150 truck went into “limp mode” last week. A wrench showed up on my dashboard, my speedometer didn’t function, and it sounded like the transmission was “winding up” if I tried to accelerate. After hitting “ok” to remove the wrench and restarting the truck a couple of times, my check engine light illuminated. I was driving at about 40 MPH when this occurred and it was a scary moment. Luckily I was able to keep my truck under control and drove very slowly back home considering I was less than 4 miles from my home. The truck went into a Ford dealership in 2024 for the “transmission recall” in which the only thing I noticed different was that I couldn’t see the digital shifting of the transmission on the screen anymore and they “killed” my battery. I still had issues every so often with power loss or the transmission shifting down abruptly, but it wouldn’t throw a code. Last week it threw a code. P0720 to be exact, the reason for the transmission recall in the first place. There was no fix done with the recall and it made it so that I had to watch my RPM’s to track my transmission shifting. This is extremely concerning especially since I was having the issues prior to a computer reprogram and it wasn’t addressed. I have also seen that there’s yet another Ford transmission recall that could affect my truck considering it was assembled in June 2014 and fits the transmission 6R80 that needs fixed. Could someone please help? Thank you.

I was driving about 75mph when my 2014 Ford F150 suddenly downshifted from 6th gear to 2nd. As a result of the unexpected downshift, my body was pushed into the steering wheel, and the rear end of the truck slid sideways as it slowed down to 65mph. The truck had a loss of power and I couldn’t accelerate. When I pulled over on the side of the highway, I used my code reader to read the codes that came up. The codes that came up pointed to Powertrain Control Module. When I looked at the PCM, it said P0720, Output Speed Sensor. I looked up the issue online and found that there is an open recall on the 2014 Ford F150 with the 6R80 transmission, and the recall is the issue I stated above. I went to two different Ford dealerships and they said that my vin isn’t listed under the recall so they won’t fix it. This is the manufacturers issue and they won’t fix it. The truck is unsafe to drive now.

Driving at highway speed, went to accelerate and pass another vehicle on a four-lane highway with my vehicle ending up in the far left lane attempting to pass. Truck lost all power, began to shake violently like it was misfiring, got an illuminated wrench on my dashboard, and at that point began to coast with no power being supplied by the engine. Miraculously I was able to coast across three lanes of highway to the shoulder without being rear ended by traffic moving at 70 mph which would have resulted in a catastrophic accident (endangering myself and my family and others on the road that day). I shut the vehicle off to stop the engine from shaking and misfiring and let it sit about two minutes. I restarted the vehicle, the illuminated wrench went away and the truck idled as normal allowing me to drive another 25 highway miles to my home without incident. Had a mechanic put a diagnostic tool on my truck to see if any error codes were thrown from it which no codes were present. Have taken it to Ford dealership near my home, they have been trying replicate the condition for three days and have been unsuccessful. Their hunch is throttle body assembly needs to be replaced ($675 fix). Quick query of NHTSB reported incidents shows a growing quantifiable history for the Ford F150 3.5L Ecoboost experiencing the exact encounter I had on this day. My family and I along with others on the highway were fortunate the event didn't end up tragically that day. Ford - time to step up and rectify via recall.
