2014 Ford F-150: check engine light

Filed Nov 6, 2026 · Electrical, Engine · TX

This is my second report with a little more detail. My vehicle is showing all signs of current recall on 2014 F-150’s. I haven’t driven it in 4 weeks because it downshifted on me while I was driving 75mph on the freeway for the second time. My speedometer dropped to 0. Thankfully I was able to exit the freeway with no incident. It restarted after 30 minutes no engine light and I was able to finish my trip. On the way back home it did it again as I was driving the backroads and to this day the engine light is still on. The engine code is P0720, the current recall code. I called my local dealer and the main Ford customer service and they both said my vehicle was not attached to the recall. I asked for a courtesy fix but they said no. I can’t afford paying to fix it even if I were to be reimbursed. Please advise me what I should do. Thank you in advance.

**VEHICLE SAFETY INCIDENT REPORT & RECALL FAILURE COMPLAINT** **1. COMPONENT FAILURE & INSPECTION** * **System:** 6R80 Transmission Molded Lead Frame Assembly / Output Speed Sensor (OSS). * **Failure:** Intermittent OSS signal loss caused the Powertrain Control Module (PCM) to misread vehicle speed and command an uncommanded, severe downshift from 5th gear directly into 1st gear. * **Inspection Availability:** Vehicle is currently located at the Ford dealership service center and is available for immediate physical and electronic inspection upon request. **2. SAFETY HAZARD & INCIDENT DETAILS** * **Risk:** Severe risk of high-speed rear-end collision, loss of control, and catastrophic injury. * **Incident:** On October 29, 2026, while driving 45 mph on an active highway, the transmission abruptly downshifted to 1st gear without driver input. This caused instantaneous rear-wheel lockup and tires screeching, bringing the truck to a complete halt in live traffic. * **Prior Symptoms:** Following the dealer-mandated software update for Recall 24S37 / 24V444, the truck experienced 5 documented transmission dropouts (5th to 1st gear) with an illuminated Wrench / Service Engine Light. **3. RECALL FAILURE & REMEDY DISPUTE** * **Recall Involved:** Recall 24S37 / the federal safety agency 24V444 (Issue Date: June 14, 2024 - 6R80 Sudden Transmission Downshift PCM Reprogramming). * **Defect/Failure:** The dealership completed Recall 24S37 (PCM software reflash). However, the software fix failed to eliminate the hazard, resulting in full rear-wheel lockup at 45 mph. * **Current Status:** The servicing dealer confirmed the lead frame must be replaced, but refuses recall/warranty coverage and is forcing out-of-pocket payment because diagnostic trouble codes were not active during the initial software flash months ago. The software remedy failed to remediate the unsafe condition, and hardware replacement is required to restore vehicle safety.

In the last month this has happened twice. While driving down the freeway my vehicle just downshifted on its own, speedometer dropped to 0, and I lost steering power but vehicle was still running. The wrench for service came on and the battery light also. As I was trying to get to a safe location the infotainment system went off first followed by my dash lighting. On the first time it happened after letting the vehicle sit for about an hour upon restart everything reset and was ok, but the engine light is still on after second incident and I'm afraid to drive it now.

The contact owns a 2014 Ford F-150. The contact stated that the vehicle was previously repaired under the federal safety agency Campaign Number: 26V378000 (Power Train); however, the failure occurred after the recall repair was performed. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted with the check engine warning light illuminated. The vehicle was taken to an independent mechanic, where a diagnostic trouble code for the transmission was retrieved. The vehicle then failed to restart and was towed to the dealer. The dealer determined that the molded lead frame needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 127,000.

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.

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.

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

I am filing a safety complaint regarding my 2014 Ford F-150 XLT equipped with the 6R80 transmission. My vehicle previously received Recall 24S37 in 2024 for the known transmission downshift safety defect involving Output Shaft Speed (OSS) sensor signal loss. Despite completion of the recall repair, my vehicle is now exhibiting the same dangerous symptoms associated with the recall condition, including: • Sudden erratic transmission behavior• Speedometer intermittently dropping to zero while driving• Wrench warning light activation• Check engine warning light• Airbag warning light• Unsafe drivability conditions and intermittent limp mode operation These symptoms create a serious safety concern because the vehicle unexpectedly changes driving behavior and loses speed signal information while operating on public roads. I presented the vehicle to Dick Smith Ford in Columbia, South Carolina for evaluation and was informed the truck requires a complete transmission replacement estimated at approximately $11,000. After extensive research, I discovered many Ford truck owners nationwide reporting nearly identical symptoms involving the 6R80 transmission, molded lead frame failures, OSS sensor failures, and unintended downshifting conditions. Ford previously acknowledged similar issues in Recall 24S37 and Customer Satisfaction Program 19N01. I am concerned the original recall remedy may not fully address the underlying hardware failure associated with this transmission system. My vehicle is demonstrating the same safety-related symptoms after the recall repair was already completed. Vehicle Information:2014 Ford F-150 XLTVIN: [XXX] I respectfully request the federal safety agency review this issue for continued safety concerns involving the Ford 6R80 transmission system and post-recall failures associated with Recall 24S37.

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.

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
