2014 Ford F-150 Powertrain (other) Problems

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.

We purchased this 2014 Ford F-150 SuperCrew (3.5L EcoBoost) used on Dec 31, 2022. Just two days after taking it home, the vehicle began experiencing sudden, violent, uncommanded downshifts from 6th to 1st gear at highway speeds. This occurred throughout our ownership. Because this was our family's only form of transportation, we had no choice but to continue driving it under these terrifying conditions, repeatedly navigating a lethal safety hazard with our three children in the vehicle until the powertrain suffered a catastrophic failure. This matches the exact defect investigated under NHTSA Campaign 24V444 / Recall 24S37 and expanded under Recall 26S45. On Dec 23, 2023, a final highway downshift forced the powertrain into 1st gear, creating immense kinetic stress and engine-braking that instantly shattered internal components and caused a severe engine knock. Less than a mile later, while trying to get our family home in life-threatening -40 degree Fairbanks winter weather with our three children inside, the engine completely blew, leaving us stranded. The Fairbanks Ford dealership initially stated that Ford would be liable for the consequential damages. However, it later backtracked, claiming that a local customer satisfaction program had "timed out" at the 150,000-mile threshold. A diagnostic certification from a local Nissan dealership has documented the failure. I was an original reporter aiding the push to reopen this failed software recall investigation, and Ford's corporate delays allowed this defect to destroy my engine before a real fix was issued. Due to this defect, our family has suffered extreme financial hardship: we spent $6,513.68 out of pocket for a 5-month Turo rental starting Christmas Day 2023; I was forced to leave my job due to a lack of transportation in a sub-zero climate; and I had to liquidate my retirement early. We have paid on time for 3 straight years on a broken vehicle and currently owe $19,633.44 on a financial ghost. Ford Motor Co

The contact owns a 2014 Ford F-150. The contact stated that while driving 50 MPH, the RPM increased with the transmission stuck in second gear. There was an abnormal sound coming from the transmission. The vehicle was pulled over, the ignition was turned off, and the vehicle was restarted, and the vehicle operated as intended. No warning light was illuminated. The vehicle was taken to the dealer to be diagnosed, and the contact was provided an estimate for the diagnostic test. The vehicle was then taken to an independent mechanic to be diagnosed, and the contact was informed that the output shaft speed sensor and the valve body needed to be replaced. The vehicle was not repaired. The vehicle was serviced under the NHTSA Campaign Number: 24V444000 (POWER TRAIN) by the owner of the vehicle, but the remedy failed to prevent the failure. The contact stated that the failure had occurred after receiving the recall repair. The manufacturer was notified of the failure and informed the contact that, since the recall was already performed, the additional repair would be an out-of-pocket expense. The failure mileage was 160,000.

My 2014 Ford F-150 was previously included in Ford Safety Recall 24S37 regarding unintended transmission downshifts caused by an intermittent Output Shaft Speed (OSS) sensor issue. The vehicle was inspected by a Ford mobile technician on January 20, 2026. No qualifying codes were found at that time, and the recall was closed under my VIN. The recall involved the risk of an unintended downshift into first gear that could result in loss of vehicle control. On August 20, 2026, while my husband was driving approximately 40-50 mph, the truck suddenly downshifted and rapidly lost speed. The vehicle would not accelerate beyond approximately 10-15 mph and had to be moved into a parking lot to avoid remaining in traffic. After parking, the truck would no longer move under its own power. The wrench warning light illuminated and the vehicle became undrivable. The symptoms experienced appear substantially similar to those described in Recall 24S37. The dealership has indicated that the current failure may involve the transmission lead frame and speed sensor system, but I am concerned that this event may be related to the same transmission downshift condition addressed by the recall. I am requesting that NHTSA document and review this incident.

While driving, the malfunction indicator light (yellow wrench) will illuminate, followed by a complete loss of communication between the instrument cluster and the transmission. The speedometer immediately drops to zero even though the truck is still moving, and other information, such as the fuel range, goes blank. The truck will also struggle to accelerate from a stop, almost as if it is starting in second gear. If I shut the truck off and restart it, everything returns to normal. Before the malfunction light comes on, the transmission will often make a very hard downshift or remain stuck in first gear and refuse to shift as speed increases. After a few seconds, the warning light appears, communication is lost, and the transmission shifts again, often very harshly. This seems to happen more often at lower speeds. This creates a serious safety risk because I lose all knowledge of my speed while driving, and the transmission may not respond properly when pulling into traffic or trying to reach a safe place to pull over. The dealer is aware of the problem. Recall 24S37 was supposed to correct it, but it did not. Recall 26S45 acknowledges that the original repair was not effective for all vehicles, but my VIN is not included even though I am experiencing the same failure. I have reported the issue to the dealer multiple times by phone and through their online service system. A dealership representative told me I am not the only customer experiencing this problem, but the dealer has not inspected the truck since completing Recall 24S37 and has not taken action or returned my calls. The malfunction indicator light consistently appears about four seconds after the transmission begins acting abnormally and immediately before the instrument cluster loses communication with the transmission. I am now nervous to drive the truck, especially from a stop or at lower speeds, because I never know when the problem will occur.

Vehicle Information: Year: 2014 Make: Ford Model: F-150 Component: Power Train (Transmission / Powertrain Control Module) Dealership Involved:Midway Motors Ford, 2075 E Kansas Ave, McPherson, KS 67460 Complaint Description:I am filing a formal safety complaint against Ford Motor Company and Midway Motors Ford in McPherson, KS, for failing to provide a free remedy under active federal safety recall 24S37 (NHTSA Campaign 24V444).My 2014 Ford F-150 was brought to the dealership to complete safety recall 24S37, which addresses severe, sudden transmission downshifts. The dealership performed a software update to the Powertrain Control Module (PCM). Immediately following this update, the truck's drivability severely deteriorated, and the transmission began violently slamming into 3rd gear, locking itself into a dangerous transmission fault "limp mode." The diagnostic scans post-update indicate a failure of the molded lead frame/speed sensor. According to Ford's official technical service bulletin for recall 24S37, physical replacement of the molded lead frame is an explicitly authorized remedy when diagnostic codes appear following the software flash. However, both the local servicing dealership (Midway Motors Ford) and Ford Corporate Customer Service are actively refusing to perform this physical safety repair free of charge. They are wrongfully claiming that because my vehicle has over 200,000 miles, it is disqualified from financial assistance. They are confusing a federal, non-expiring safety recall with an older, expired warranty extension program (19N01).By refusing to replace the defective lead frame that their own software update triggered into an active failure state, the manufacturer and dealer are leaving my vehicle in an unsafe, undrivable condition and violating federal recall mandates. I request that NHTSA intervene to compel Ford to complete the mandatory safety recall remedy at zero cost to me.

Incident

Jul 25, 2026

The vehicle experienced an uncommanded, severe downshift from 5th gear directly into 1st gear while traveling at approximately 45 mph on a public road. This caused sudden, violent engine braking and an immediate drop in speed, creating an extreme rear-end collision hazard and potential loss of vehicle control. This vehicle previously received the PCM software update under Ford Safety Recall 24S37 (NHTSA Campaign 24V444). The software update failed to prevent the sudden downshift event caused by the failing Output Shaft Speed (OSS) sensor on the transmission molded lead frame. When contacting Ford Corporate Customer Service and local dealerships, Ford refused to cover diagnostic scanning or hardware replacement, claiming the recall is marked "completed" in their database because the software patch was installed more than 12 months ago. A software update that fails to prevent a 5th-to-1st downshift leaves a defective physical sensor on the road. Ford is refusing to evaluate or remedy a persistent, life-threatening recall failure on a 6R80 transmission.

I brought my 2014 Ford F-150 to Gentilini Ford in Woodbine NJ in response to recall notice number 24S37 on XXX for an issue with the molded leadframe on the 6R80 transmission. The recall gave the option of reprogramming the existing leadframe or replacing the leadframe. My leadframe was reprogrammed and not replaced. Shortly after the recall while driving back to [XXX] from NC, the transmission dropped into first gear while cruising down a narrow road causing the back tires to chirp. Several dash lights then came on and the transmission went into limp mode which included rough shifting, sluggish starts, no speedometer or several gauges. When I made it to a point where it was safe to pull over, I immediately turned off the truck and did a visual inspection to make sure there was no damage. I returned to my truck began researching the issue online and quickly realized that it was caused by the actions taken during the recall. I placed several calls to Ford with no recourse. In late May of 2026, I learned of a new recall aimed at the correction of the recall and Ford was replacing the leadframes that were reprogrammed. Upon further research, I learned that late year 2014 f-150's with the 6R80 transmission were not included in the recall. I am reaching out for help in forcing Ford to include my truck in the recall. The issue happens almost every time I drive now and will eventually reset back to normal mode after several stops and restarts. It is a very dangerous situation when my speed drops dramatically on the narrow roads of North Carolina. There are no shoulders on the roads and the only place to pull over in the majority of situations is into a drainage ditch. Please help!!!

On July 2, 2026, the vehicle was brought to an authorized dealer for a scheduled appointment to resolve active Safety Recall 26S45 / NHTSA Campaign 26V378 (6R80 transmission sudden downshift defect). The dealership refused to perform the recall software update, claiming it was not needed for the vehicle. On July 12, 2026, while traveling at highway speeds on a public highway, the transmission suffered the exact un-commanded sudden downshift described in the recall. The violent mechanical force instantly snapped the rear driveshaft in half and severed the undercarriage air conditioning lines, creating a sudden, life-threatening loss of control and wheel speed reduction on a live highway. The vehicle is now permanently disabled due to the dealer's refusal to fulfill a federal safety mandate.

Traveling at 65mph on I-275 in Tampa while changing lanes vehicle suddenly downshifted to 1st or 2nd gear enough to cause the vehicle to jolt and squawk the rear tires. The vehicle remained in this state with elevated rpm's and gear indicator was blank. This has occurred on many occasions and is extremely dangerous. It has been an ongoing problem that Ford refuses to correctly solve. It's already been in for service under prior recall which hasn't really solved anything. The 2013 models had the same issue which Ford issued a replacement of the lead frame, yet now they continue to slap bandaids on with software patches. The software doesn't solve the problem of a garbage lead frame.

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
