2015 FORD F-150 Complaints

The contact owns a 2015 Ford F-150. The contact stated that while driving 55 MPH, the transmission downshifted from 5th to 4th gear, and the vehicle decelerated to 35 MPH. The failure reoccurred, and the transmission downshifted from 3rd to 1st, and the vehicle lost automotive power. The message “Service Vehicle Soon” was displayed and the check engine warning lights were illuminated. The vehicle was towed to a dealer where it was diagnosed, and the contact was advised that the cooler lines had snapped due to corrosion on the quick-connect clamp. Additionally, the contact was informed that the transmission needed to be replaced. The cooler lines were replaced; however, the transmission was not replaced, and the vehicle was not repaired. The contact referenced NHTSA Campaign Number: 26V237000 (POWER TRAIN) as a possible cause for the failure. The manufacturer was notified of the failure. The failure mileage was 79,236.

I have contacted Family ford in netcong NJ on two separate occasions to address recall Manufacturer Recall Number20S31 NHTSA Recall Number20V332 Recall StatusRecall Incomplete Initially in 2020 I was on a waitlist; I followed up a few times and never heard back. Recently I contacted them again to address a second recall and schedule the work for Sept 6th. I received a call from their scheduler stating the above parts were on backorder for several months and said I would be put on a waiting list. I asked what specific part number was on order but she had no information but stated it could be 6 to 9 months and she was unable to follow up with me when it was available. After our call I did a search on their parts inventory and the brake booster, o-rings and gasket were all in stock and available for pickup that day Saturday August 22nd 2026. It is clear that they are intentionally delaying the installation of the of this critical stopping component.

I was in my driveway getting ready to service the truck. After depressing the break pedal about half way, I lost break pressure. Upon inspection, the front passenger side breaks had a major leak/failure. The entire inside of the front passenger wheel as sprayed with break fluid. This indicates that the line failed under pressure and had and explosive release of fluid. Upon further inspection the line failed at the hard metal fitting leading to the hard metal break lines. In one of the pictures provided I am pointing at the exact point of failure. This is similar to other reported failures: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2015 Ford F-150. The contact stated that an engineer was sent from the dealer to the residence and the vehicle was repaired under NHTSA Campaign Number: 26V237000 (Power Train); however, after the recall repair, the message that the top speed of the vehicle was limited to 80 MPH was displayed. Additionally, the transmission was shifting roughly while shifting gears. The contact stated that the failure started after the recall repair was performed. The dealer was contacted after the recall repair due to the failure but stated that over time the transmission would shift better. The manufacturer was not made aware of the failure. The failure mileage was approximately 200,000.

Component: Power Train / Automatic Transmission (6R80 6-Speed) Description of Incident & Safety Hazard: My 2015 F-150 suddenly lost the ability to shift through its full range of gears and became completely locked between 3rd and 5th gears while driving. This sudden loss of power and gear range in active traffic created an immediate rear-end collision hazard. The vehicle threw diagnostic trouble codes P0720 (Output Shaft Speed Sensor) and P0722 (Output Shaft Speed Sensor No Signal). I have photographic proof of these active codes. The Safety Recall Loophole: I brought the truck to a Ford dealership for safety recall 26S28. However, the dealer only performed a PCM software update and did not replace the physical molded leadframe. Because safety recall 26S28 strictly excludes codes P0720 and P0722 from its replacement criteria, the dealer is completely unauthorized to replace the physical leadframe under this safety campaign, regardless of whether the codes are active. Inexplicably, Ford covers codes P0720 and P0722 under safety recall 24S37 (for older models), but forces 2015 owners with the exact same codes to rely on a non-safety Customer Satisfaction Program (26N04) which carries strict time/mileage limits. This is a dangerous technical loophole. A software patch on a vehicle with a physically failing speed sensor is a temporary band-aid, not a permanent safety fix. The physical leadframe is still defective and will fail again, presenting a continuous safety hazard. Ford must expand safety recall 26S28 to mandate the physical replacement of the molded leadframe for all vehicles presenting with leadframe-related codes, including P0720 and P0722. The vehicle is currently available for inspection.

The contact owns a 2015 Ford F-150. The contact stated that the vehicle was serviced under NHTSA Campaign Number: 26V237000 (Power Train); however, after the recall repair was performed, the vehicle started experiencing failures associated with the recall. The contact stated that after the recall repair, while driving 60 MPH, the transmission unexpectedly downshifted to a lower gear and the vehicle swerved in the middle of the highway. The vehicle was taken back to the dealer and was diagnosed with transmission failure. The leadframe was installed on the vehicle, but the failure persisted. The manufacturer was made aware of the failure. The failure mileage was approximately 210,265.

The contact owns a 2015 Ford F-150. The contact stated that while driving at an undisclosed speed, the vehicle was shaking abnormally, with the WRENCH symbol flashing before the vehicle lost power. The contact associated the failure with NHTSA Campaign Number: 26V237000 (Power Train); however, the VIN was not included in the recall. The dealer was contacted; however, the vehicle was not diagnosed or repaired because the dealer was unable to duplicate the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 240,000.

The transmission intermittently enters a failure mode where the wrench warning lamp illuminates and the transmission locks into its current gear, with no further shifting. This has happened multiple times without warning, including at highway speed. It sometimes recovers on its own and resumes normal shifting, then fails again later. The safety risk is loss of gear selection while moving. Depending on the gear it locks into, the vehicle cannot accelerate to merge or maintain traffic speed, or the engine runs at high RPM with no upshift available. The manufacturer has issued a safety recall for this vehicle line citing unexpected transmission downshift as the hazard, which is the same underlying condition. My family rides in this vehicle and I no longer consider it safe. A Ford dealer confirmed the failure. Codes P0715 and P0717 (input/turbine shaft speed sensor circuit) were retrieved from the powertrain control module. No gear ratio codes and no slip codes were present, indicating an electrical fault rather than mechanical failure. The dealer performed the PCM reprogramming remedy under safety recall 26S28. The condition recurred the same day, on the drive home from the dealership, and has continued since. A software calibration cannot repair a degraded electrical connection, so the remedy did not address the failure on this vehicle. The manufacturer's stated root cause is degradation of electrical connections within the transmission molded lead frame. The transmission range sensor circuit and the turbine shaft speed sensor circuit both run on that same lead frame and terminate at the same case connector. Customer Satisfaction Program 26N04 covers lead frame replacement only when transmission range sensor codes are present. My vehicle is exhibiting failure of the same component through a different circuit on that component, and is excluded from the program despite the same part failing in the same manner.

vehicle: 2015 Ford F-150 XLT, 5.0L V8, approximately 148,000 miles. I previously had the related recall/software update performed on this vehicle. On two separate occasions the transmission performed a sudden, uncommanded downshift while driving at highway speeds. On one of those occasions the rear tires locked up / skidded. There was no warning, no driver input, and no diagnostic trouble codes (DTCs) were stored or displayed. After these events, a Ford dealership inspected the transmission and found metal debris in the transmission pan. This is how the current transmission problem was discovered. My symptoms match the defect described in NHTSA recall 26V237 / Ford campaign 26S28 (and the prior investigation PE25002 / EA26001): intermittent loss of Transmission Range Sensor signal due to degradation of the molded lead frame, resulting in unintended downshifts that can cause rear-wheel lock-up. I am requesting that Ford review this case for coverage or goodwill assistance related to the known lead-frame defect and the subsequent internal transmission damage.

The contact's parents own a 2015 Ford F-150. The contact stated that while driving 40 MPH, the transmission unexpectedly downshifted from sixth gear to second gear, causing the vehicle to jolt and the wheels to lock up. The brake pedal was depressed, but the wheels remained locked, causing the vehicle to crash into the rear of another vehicle, which then struck a second vehicle. No warning light was illuminated. The air bags failed to deploy, and no injuries were reported; however, emergency personnel responded to the scene and evaluated an infant occupant of the second vehicle. A Police report was filed. All three vehicles were driven away from the scene. The contact received notification for NHTSA Campaign Number: 26V237000 (Power Train); and contacted the dealer. The contact was referred to the manufacturer to determine whether the crash was caused by the recall. The manufacturer was unreachable. The vehicle was not diagnosed or repaired. The failure mileage was approximately 71,700.
