The contact's grandfather owns a 2020 Ford F-150. The contact stated that while driving, the message "Transmission in Park" was displayed with an audible chime constantly. Upon investigation, the contact discovered NHTSA Campaign Number: 26V402000 (Power Train) and associated the failure with the recall. The dealer was notified of the recall, and the contact was informed that the VIN was not included in the recall.
I am reporting a safety-related transmission problem I experienced with my 2020 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly lost power engine revved up and started to buck . This occurred while I was going down the coastal range pass while towing my boat, creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration or propulsion. I believe this incident may be related to the known 10R80 CDF clutch-cylinder/sleeve problem. Ford technical information identifies axial movement of the CDF sleeve that can cause hydraulic-circuit leaks and harsh or delayed engagement and shifting. This condition can result in slipping, RPM flares, delayed engagement, unexpected gear changes, harsh downshifts, lurching, or loss of propulsion. This is a safety concern, not merely a transmission quality or reliability issue. Unexpected loss of propulsion or unpredictable shifting while merging, accelerating into traffic, crossing an intersection, turning, or traveling at highway speed can create a collision hazard. Because I personally experienced this unexpected transmission event, I request that NHTSA investigate the 10R80 CDF clutch-cylinder/sleeve condition in Ford F-150s. Please review Ford warranty claims, dealer repair records, transmission replacements, consumer complaints, and field-failure data to determine whether this is a safety defect requiring a recall. I believe owners should not have to wait for a potentially dangerous transmission failure before this known condition is addressed. Thank you for your consideration.
It will lose all power sometimes during 1-2 or 1-3 shift and not complete the shift causing you to be powerless in front of oncoming traffic while turning left on green across traffic. Then eventually slams into gear violently. This last time was not the first but two of my kids were in the truck this time. I have not had it to the dealer yet but after much research online this is a known problem and I have a pretty good idea of what they’re going to tell me. No check engine light.
A sudden transmission slip or hard shift into 8th gear every time. feels like someone is hitting the brakes just slightly when driving 40-50mph transitioning from 7th to 8th. sudden jerk when shifting into 4th more irregular but once a day at least.
Passenger side and passenger side rear door sensors say the door is a jar even though it’s not. Opened and closed doors numerous times to make the warning message go away. Seems water or something gets in the sensors, causing the faulty sensors to go off doors will not lock and makes the alarm system go off randomly.
Transmission has hard/harsh shifts and delayed gear engagement that began around 56,000 miles and have become much worse at 68,000 miles. The delay in engagement when accelerating from a stop, pulling into traffic or merging is a safety concern. A Ford dealer performed a transmission adaptive relearn and software update, but the symptoms continued. The dealer did not verify hydraulic leakage or perform the full diagnostic described in Ford TSB 25-2126 (MC-11016931-0001, harsh/delayed shifts on 2017-2020 F-150), and the only recommendation was to replace the entire transmission at roughly $5,000 after the powertrain warranty expired at 60,000 miles. The incident date entered is today because the symptoms are ongoing and progressive: they developed gradually since about 56,000 miles and are heading toward ultimate transmission failure. Safety concerns: hesitation and delayed engagement when pulling into or merging with traffic, the truck possibly rolling back when engaged on hills, and loss of reliable power on hills.
On XXX, while the vehicle was parked and not in use, the passenger-side front coil spring abruptly fractured, causing the front passenger side of the vehicle to drop onto the tire. The failure also damaged additional components. The vehicle and failed component are currently located at Hines Park Ford in [XXX], and are available for inspection upon request. This failure presented a serious safety concern. Had the spring fractured while the vehicle was traveling at highway speeds, the sudden drop in the vehicle’s front end, contact with the tire, and damage to additional components could have resulted in a sudden loss of vehicle control, potentially causing a serious crash, significant injuries, or fatalities. I am unaware whether the failure has been independently reproduced. However, the dealership inspected the vehicle and confirmed that the coil spring had broken and that additional components were damaged as a result. There were no warning signs, unusual noises, dashboard warning lights, or other noticeable symptoms before the failure. The spring fractured abruptly and without warning while the vehicle was parked. The sudden failure of a critical suspension component on a vehicle that was not in motion raises serious concerns about the component’s reliability and the potential consequences if the same failure occurs while driving.

while driving on the highway, my 2020 Ford F-150 equipped with the 10R80 transmission experienced a sudden and catastrophic loss of power. The transmission failed to shift slipped gears, and left the vehicle completely neutralized in traffic. This sudden loss of propulsion created an extremely hazardous situation on the road, nearly causing a severe collision before I could safely pull over.
The contact owns a 2020 Ford F-150. The contact stated that while driving at an undisclosed speed with children inside the vehicle, the transmission shifted erratically and began shuddering. The vehicle decelerated unexpectedly. The contact stated that the check engine warning light was intermittently illuminated. The manufacturer and the dealer were notified of the failure. The failure mileage was 90,000.
The Transmission has failed. Hard shifting, random gear switching while driving at any speed. i put it in reverse and it went forward while in reverse. it slows itself down while on the highway. it acts like it wants to turn off while running, its a matter of time before I'm driving down the road and it decides to stop suddenly and cause an accident. I got it diagnosed by truck works garage and they confirmed that the shifting was all over the place with random high rpms. The dealership quoted me $2500 just to diagnose the problem so i had it diagnosed at truck works garage for $160 to confirm the issues matched the tsb's and recalls that they wont acknowledge my VIN for. The failure 1st appeared 5 years ago when i was under warranty, i took it in (and have the work order still dated 10/22/202) for hard shifting and they brushed me off and sent me away with false information about the cause. 5 years ago (25 days before i brought it in for the hard shifting) there was a tsb 21-2315 published for the exact issue on my truck, They ignored it and sent me away without fixing anything or addressing the issues.
I put my truck in reverse to get out of a driveway and it kept going and accelerating...the brakes did not work. I ended up goign through a fence at the end of the street and into a shed and my truck finally stopped. I have significant damage to my truck as well as to the homeowners property...the Police classified it as equipment failure and I did not receive a ticket.
The contact owns a 2020 Ford F-150. The contact stated that after the check engine warning light illuminated on two occasions, the vehicle was taken to the dealer, where the catalytic converters were replaced under warranty. The contact stated that the check engine warning light was intermittently illuminated. The vehicle was taken back to the dealer, where it was determined that one of the catalytic converters needed to be replaced. The contact was informed that the manufacturer would provide partial financial assistance for the repair. Additionally, the contact stated that the fuel efficiency had decreased after the failure started. The manufacturer was notified of the failure by phone. The failure mileage was approximately 30,000.
I am writing to formally report a severe and dangerous safety defect regarding the 10R80 10-speed automatic transmission in my 2020 Ford F-150. While driving, the vehicle routinely experiences a complete "neutral-out" or severe shift flare when attempting to transition out of 1st gear. Instead of engaging 2nd or 3rd gear, the transmission completely drops out of gear into a false neutral. During this failure, the vehicle experiences an immediate and total loss of forward propulsion for several seconds while the engine revs freely. After a dangerous delay, the transmission violently slams back into gear. This is an acute safety hazard. Losing all forward acceleration unexpectedly—specifically when pulling out from a complete stop, navigating intersections, or merging into fast-moving traffic—leaves the vehicle stranded and completely defenseless against oncoming traffic. It creates an immediate risk of a severe rear-end or broadside collision, as trailing drivers do not expect a vehicle to suddenly lose all power. Ford is fully aware of this mechanical defect, as documented in their internal Technical Service Bulletin TSB 25-2126 (and its predecessors). The bulletin notes that an internal CDF clutch drum bushing physically slips out of place, blocking hydraulic fluid passages and starving the transmission of pressure. Because this is a known factory engineering defect that causes an unpredictable loss of propulsion in active traffic, it should be treated as a critical safety hazard rather than a standard wear-and-tear component. I urge the NHTSA to investigate this systemic 10R80 CDF drum failure to protect consumers from catastrophic accidents.
I have noticed that my turn signal lights work sometimes, and sometimes they give me the rapid-fire warning light indicating that one of them is out (front or back). The outage may or may not last the entire duration of when the turn signal is deployed - sometimes it fixes itself, and other times it remains out. Sometimes, it even fixes itself and goes back out in the same signal instance. Additionally, I have noticed that one or both of the headlights will sometimes fail. I have learned to turn on the fog lights in order to ensure some sort of light remains working to illuminate my path forward. I've not yet experienced the fog lights going out as they seem to be unaffected by the intermittent outages. If it wasn't for this, I would have stopped driving at night altogether. I have already begun limiting my time on the road after dark, and attempting to handle anything that requires transportation earlier in the day. Please feel free to reach out with any additional questions, as I'd like to ensure this gets resolved for myself and any others ASAP!
It had been raining hard for a few days. Husband was taking truck down hwy 98 to a drs appointment an hour away. Driving 50 when the steering wheel starting going in and out, the seat started moving forward and back, running boards going in and out, lights flashing on and off and horn blaring and the 2020 F150 sputtered, almost stopped in the middle of the road; to name a few things. Frightened he was able to pull into a gas station, wait a bit then try another time when same happened. He eventually made it to his appointment. Came out and truck doing same. Was towed to Group 1 Ford dealership in in Pensacola. They had it a week and their mechanics could only say it was the BCM, Body Control Module that was wet and malfunctioned. Recommended an $8,000 dollar replacement but as they could not find the problem suggested we wait till we found it. After 10 days at the dealership, they couldn't. I, a 67 year old woman did. The upper windshield was leaking over the A and B pillar and the drops were landing on the BCM. I have pictures. l If they had taken the side panels of dash off by door they would have found it also. Husband could have died
My [XXX] son was at a stop light and when the light turned green he started to turn left. As he was turning left, the steering wheel started to pull left to the point that he couldn't steer it back, almost as if it was stuck and kept pulling left. He fought with it and tried to press the break. This caused him to hit the center median of the street ([XXX]) and the truck flipped and landed on driver side. My son took off his seatbelt and climbed out of passenger window. Another person that helped him told him that they saw him struggle with the steering wheel. However, since my son is [XXX], he didn't know to gather witness information. A police report was completed and I'm waiting to receive it. However, he was not cited as he was not speeding and had only simply turned left at the signal. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Transmission shifting very harshly. Especially in gears 3-4-5. Transmission will stop with no control, then abruptly slam into gear. 80,000 miles. Issues since new. Dealership says vehicle needs new transmission. Will factory assist at $3,700, my share $5,600. Ford has history with this transmission. Why didn’t they replace when in warranty?
Brought my 2020 Ford F150 2.7L EcoBoost in for mandatory emissions recall 24E12. Vehicle had zero dashboard lights or performance issues prior. Immediately upon completion of the PCM flash, the check engine light activated. When the truck was scanned I am now receiving a P0420 and P0430 catalytic converter efficiency codes. The dealership is now requiring $6000 for replacement of qty 2 catalytic converters caused by the recall parameters. This is a predatory compliance software update designed to shift manufacturing component failures onto the consumer after the 80k mile warranty window (truck has 105k). I have filed a complaint with Ford and asked for a P01 Financial Review for After-Warranty Assistance and have been told there is nothing Ford can or will do to assist and I must pay them $6000 if i want them to fix this. Because of this the vehicle is now not emissions compliant.

Truck suddenly shifted from gear 8 to gear 2 then 4 reducing my speed suddenly causing other vehicles to almost hit me at around 40 mph. I drove home with the transmission erratically shifting up and down Even though I kept my speed under 30 mph. That was about 10 days ago and I made an attempt to drive it a few days ago after researching and in the same result happened. It seems I have been victimized by the CDF drum crawling out of its space leading to an imbalance of transmission fluid pressure. About 2 miles after the initial problem. A wrench symbol appeared on the instrument cluster with a message under it that says see manual. Just as every time I've tried to find something in the manual. After spending several minutes of frustration, I still never found the wrench symbol or what it means.
The contact owned a 2020 Ford F-150. The contact stated that while the vehicle was parked with the engine running, there was an abnormal sound coming from the vehicle. The contact's spouse, who was seated in the front passenger seat, saw smoke coming from under the dashboard. The contact's spouse exited the vehicle. The contact stated that while attempting to open the front driver's door, the front passenger's side of the dashboard and the windshield caught on fire. Additionally, the front passenger's door was on fire. The contact's two dogs were seated in the rear seat. The contact entered the vehicle through the fire and removed the dogs from the vehicle. The contact used a neighboring building's water hose and extinguished the fire. The contact stated that within two minutes, the vehicle was engulfed in fire. The fire department later arrived. The Fire Chief inspected the vehicle, and the contact was informed that the fire had started in the engine compartment. The contact was transported by ambulance and received medical treatment. The contact sustained second-degree burns on the left and right legs and left and right elbows and forearms. In addition, the contact sustained second-degree burns on the left and right hands. The vehicle was towed to a local tow yard. A Police report was filed, but the information was unavailable. The contact had received notification of NHTSA Campaign Number: 25V442000 (Back Over Prevention). The manufacturer was contacted by phone and made aware of the failure. The failure mileage was approximately 9,000.
The contact owns a 2020 Ford F-150. The contact stated that while driving, the vehicle jerked abnormally, experienced a transmission shifting delay between gears, and occasionally slipped out of gear. The contact stated that after slipping out of gear, the transmission failed to re-engage gear and slipped continuously. The vehicle was inspected by a transmission specialist, who confirmed the failure and determined that the transmission needed to be replaced. The manufacturer was notified of the failure. The failure mileage was unknown.
Transmission slips gears and sometimes shifts violently. I took the truck to a Ford dealership for an assessment and was told I need to replace the whole transmission. I also have a problem with oil consumption from the engine. I was told by the same dealership that this was a known problem with the 5.0 engines built from 2019 to, I believe 2023 and that it would require an engine replacement. I bought this truck from an individual and now I am stuck with it.
The 10R80 transmission failed internally due to the defective CDF clutch drum assembly. Vehicle experienced dangerous gear dropping/slipping. Forced to pay out of pocket at an independent shop for a total rebuild. I have not seen anything from dealer. It was inspected by an independent shop. There was no warning prior to the failure. This happened right over 100,000 miles.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
