Ford F-150 2020

Vehicle had hard and sudden shifting and grinding noise coming form gears. Sudden shifting would result in abrupt change in speed. Two repairs were made by a Ford dealership totaling just over $10,000 including replacing transfer case and transmission. There was no vehicle warning indicators that notified me of this problem.

Transmission failed Transmission locks up slamming vehicle to a stop. transmission sometimes will not change gears and go into neutral when driving down highway. Dealer has confirmed problem and stated that ford knows that it has a faulty CDF drum in transmission. there were not any warning lights before this started occurring.

My transmission hard shifts from 1st to 3rd. It really switches in 2nd gear. It also hard shifts into 5th and 8th gear. Sometimes it misses the gear almost like I’m in neutral. This happens when I’m in 7th or 8th gear. Plus, if I’m on the highway and I need to accelerate, I feel a hard clunk while changing gears. This started in May.

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?

Transmission failed. Truck jerks at stop. Transmission went out at 68,000 miles. My dad has a 2019 with same problem and went out at 72,000 miles. Someone needs to hold ford accountable for this. Extended warranty didn't want to pay the full price. Now I am out of pocket $1,800. Going to file a lawsuit against Ford and the extended warranty company

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.

Transmission shifted from 4th to 1st while driving a steady 25 mph, then lost all forward drive, the transmission slips, then will slam into gear. I parked it for two weeks until I could get it to the shop. Driving it to the Ford dealer today (2 September 2026) I had to stop the vehicle twice because the transmission was doing the same thing. Currently have 70K miles on it.

The contact owns a 2020 Ford F-150. The contact stated that while driving 30 MPH, the transmission jerked while shifting gear. The failure was a recurring failure. The dealer was contacted and the vehicle was diagnosed with CDF drum failure. The contact was informed that the transmission needed to be replaced. The manufacturer was contacted by phone and made aware of the failure. The failure mileage was approximately 40,500.

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 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.

The contact owns a 2020 Ford F-150. The contact stated that the message on “Powertrain Malfunction – Reduced Engine Power” was displayed on the Ford App. After the message was displayed, while driving at an undisclosed speed, the vehicle failed to exceed 30 MPH. A certified mechanic was contacted and stated that the failure was associated with the transmission. The vehicle was repaired. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 90,000.

The contact owns a 2020 Ford F-150. The contact stated that while driving at various speeds, there was a delay in the transmission shifting, and the vehicle hesitated while accelerating with the accelerator pedal depressed, and the vehicle jolted. The engine revved to 7,000-8,000 RPM. The vehicle was taken to an independent mechanic, who determined that the transmission needed to be rebuilt or replaced. The contact associated the failure with Technical Service Bulletin: 25-2301 (Harsh/Delayed Engagement and/or Harsh/Delayed Shift) and Technical Service Bulletin 25-2475(Harsh/Delayed Engagement and/or Harsh/Delayed Shift). The failure mileage was approximately 88,000.

Transmission shifting issues. Have taken it to the dealerships and they stated it is "normal". Hard shifting and sometimes stalling out when trying to shift into first. The hard shifting on interstates is hazardous because it feels like the whole truck is about to lock up at highway speeds. Stalling is a hazard as well for my and surrounding traffic when it revs but suddenly wont move. No warning lights or messages displayed. Dealer is aware of the same issue affecting multiple vehicles with the same Transmission. They refuse to properly fix the issue stating its normal. It is not normal. Its concerning for my and my families safety. As well as the safety of others around me when driving on the highway.

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.

Transmission issues that are in line with what seems to be a well known 10R80 issue with a poorly engineered CDF drum. Transmission will randomly shift from a high gear down to first generating a ton of noise and impacting the handling. It has not become a permanant failure yet but is an extremely well known issue that always results in a transmission rebuild with updated/correctly engineered components at MY expense. I am worried it will cause a rear wheel lockup or a damaging amount of engine rpm one of these days. It is sporadic and isn't something that has been duplicated by a technician due to it being isolated and completely random in occurrence. It definitely seems to do it more often when it is cold out.

While driving truck down highway with cruise set at 68mph . I was in a bit of incline( not towing) vehicle violently downshifted from 10th to 1st . Service powertrain wrench came up on dash . Vehicle was derated . I came to a stop and shut down key off restarted . Vehicle operated normally again. Took vehicle to ford dealership where they could not find any issue . They also installed a pcm update at that time. Since then the vehicle has a harsh 3-4,5,6 shift and flaring in 7,8,9&10. I am convinced and concerned that the transmission is hurt due to what happened. Ford quoted 13,000.00 to install a new transmission. The truck has never been abused. I don’t wish what is happening to me on anyone as a inexperienced driver in winter conditions would have caused a major accident.

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 owns a 2020 Ford F-150. The contact stated that while operating the vehicle, the transmission was shifting hard, jerking, and downshifting unexpectedly and randomly switching gear. The vehicle was taken to the local dealer on several occasions over the years for the recurring transmission failure. The transmission software updates were performed but the failures persisted. The vehicle later stalled and was towed to the local dealer who diagnosed that the transmission CDF drum had failed and needed to be replaced. The vehicle was not repaired and was later towed to the local transmission specialist who confirmed the failure and replaced the CDF drum and the vehicle was repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 30,000.

2020 Ford F-150 Raptor supercab with 47,500 miles. Front right coil spring broke into several pieces while sitting in the driveway. Rust on one half of the piece that fell on the driveway indicates rust coating failed and caused the initial break in the coil spring. The way the coil spring broke and the vehicle lost ride height could have killed me if I were underneath changing the oil. If it had broke while driving, it would have caused an accident from loss of control endangering vehicle passengers and others on the road.I will keep all parts and have available for inspection. In hindsight, the only sign this was a problem was noise while driving over speed bumps and it was inspected by several different shops (Ford, VA inspection, two auto body shops) over the last year while it presented the noise. The truck has not been inspected since the coil spring broke.

The transmission would not shift out of second gear turning onto a busy highway and my pregnant wife and I were almost rear ended. It then went to first and hard shifted out of gear putting excessive pressure on our midsections. The cause most likely is a well known issue that ford engineers knew about and negligently ignored for several years with the faulty 10r80 transmission. It is not known whether it was a valve solenoid issue or the cdf drum issue but both are very common issues. My wife could have had issues from the stress of the incident and maybe the pressure from the seatbelt. The probelm has not been confirmed or inspected but i cant not afford testing since transmission doagnostics are extremely expensive. I have attched a summary from my own diagnostics of similiar events as the problem still exists. The system is available for inspection upon request.

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)

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.

the 10 speed transmission at low transmission temps shifts extremley hard to the point where it will down shift in a slow acceleration back to first gear and chirp the tires, in the rain this could cause me to lose traction in adverse weather conditions. Somtimes it will shift into to neutral and not accelerate at all for a few seconds before shifting back into first gear, making it dangerous if I im trying to cross a road and the truck essentially stalls for a few seconds blocking the road way. The last full service oil change i had said the transmission fluid was correct. on online forums i have seen a lot of the same issues with other owners. I asked ford dealership about it and they told me to drive it until a warning light comes on. this sounds like some issue with the transmission itself and not a wear and tear issue as i have 100,000 miles on the truck and do very little towing with it.

2020 Ford F-150 custom-built in Sept 2020 developed severe, textbook warning signs of rear-end failure while traveling—specifically severe low-speed metallic clanging and high-pitched whirring from the rear wheels. Recognizing the potential danger, we safely exited the highway and sought an immediate diagnostic from an independent shop. The diagnostic confirmed the defect mechanism detailed in NHTSA Campaign 23V896000: fractured axle hub bolts, disintegrated pinion gears, and metal shaving contamination throughout the 9.75-inch axle housing. While we avoided a high-speed highway shutdown by proactively seeking repairs, the underlying structural manufacturing defect is identical to the active recall. My truck's build date sits squarely inside the part production window specified by Ford in that campaign (starting Jan 28, 2020), but my VIN is excluded due to a generation cutoff. Note: We have retained the full replaced axle assembly fully intact and available for physical inspection by NHTSA investigators.

After starting my 2020 Ford F150 for the last few months on the dash 2 warnings comes up, Front Camera Malfunction Service Required and Pre Collision Assist Not Available. These come on every time I start my truck. I did go to my local Ford dealer and told them these were coming on and they told me they never heard of that. I did have a mechanic do a scan on the truck and he came up with code 4300-49- AF which he said is an internal electronic failure. I have read that people have been having this same issue with their 2020 Ford F150s. I feel this is a safety issue that Ford should address. When system is not working it could lead to accidents which is why this would of been installed on vehicles. I have not had the issue fixed due to the fact the dealer told me they had never heard of this issue and would have to put it on a machine to see if they could even figure out the problem which could run into hundreds of dollars plus repairs and I am on a fixed income. Vehicle is available about any time to check this out.

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

Our 2020 Ford F150 transmission failed at 80k miles. Ford USA offered to pay half of the repair cost but is not willing to take full accountability on a transmission that was never was put under stress. Our truck never towed anything and was only use to drive from the shop to the job site and with only 1 up to 2 passenger only max. Per google research: The 2020 Ford F-150, equipped with the 10R80 10-speed automatic transmission, commonly experiences harsh, erratic, or delayed shifting, sudden jerking or lunging between gears, and gear slippage. These issues stem from software calibration flaws in the adaptive learning system or mechanical wear on internal components. Common Symptoms and Issues Rough Shifting: Hard, delayed, or clunking engagement when shifting between lower gears, especially on cold starts. Lunging or Hesitation: Sudden forward surges or hesitation when trying to accelerate from a rolling stop. Gear Slippage: Temporary loss of power delivery or failure to catch the next proper gear cleanly. Shift Cable Clip Recall: A limited recall addressed a faulty shift cable lock clip where the gear indicator might show a different gear than what was actually selected, increasing rollaway risks

Transmission started "clunking" and shifting erratically over a two week period before warning light came on that said "powertrain needs attention...contact dealer" Took the car to Monticello Ford in Monticello NY and they tested it based on diagnostic code and replaced filter and fluid. They reset the computer and told me to drive it for a week so computer could "relearn" driving habits. Drove truck for 4 days and once again transmission started clunking and shifting hard with loud thunks when transmission gears engaged. Had my [XXX] grandaughter in the truck with me on the highway when the transmission started to slip and would not engage. Other vehicles had to brake suddenly to avoid hitting me. Had to pull over and restart truck to get the transmission to re engage. Transmission issues have been a known problem with the Ford F 150 trucks since 2017 and yet Ford has done nothing to correct the problems with their customers.....there are currently three outstanding class action lawsuits against them regarding the faulty transmissions.....this is a SAFETY issue that Ford must be held accountable for and fix these trucks at NO COST to the customers who own these trucks immediately!!!

My 2020 Ford F-150 (5.0L V8) experienced a sudden loss of engine power and stalled completely while I was driving. In the days leading up to this, the check engine light had illuminated, and I later discovered the vehicle had consumed a severe amount of engine oil — the dipstick read below the "add" line. Critically, no low oil pressure warning light or audible chime alerted me to the oil loss before the stall occurred. After the initial stall, the engine continued to struggle to maintain idle and stalled repeatedly whenever RPM dropped to approximately 1,000, making the vehicle unsafe to drive. I had the vehicle towed to a Ford dealership for diagnosis. The dealership's estimate confirmed the need for a full engine (long block) replacement, at a cost of approximately 19,824.56 (total estimate 21,491.04). I am aware that Ford issued Technical Service Bulletin 19-2365, which acknowledges that 2018-2020 F-150 trucks with the 5.0L engine may experience excessive oil consumption exceeding one quart per 3,000 miles with no visible external leaks, attributed to oil being drawn into the engine during deceleration fuel shut-off events. I believe this defect directly caused my vehicle's stalling and oil starvation, and that the lack of any dashboard warning prior to the failure is a separate and significant safety concern, since a driver has no way to know the engine is being damaged or that a stall is imminent.

We purchased a used 2020 F­150 in late summer 2024. We brought it in for issues in November 2024, but the Ford dealership found no repairs were needed. We returned in March 2025 when the CDF drum failed requiring a transmission rebuild, a known issue with Technical Service Bulletin but not a recall. The engine continued consuming oil after this despite Ford completing all applicable service bulletins and advising there was nothing further to do. We took the vehicle in for service in May, 2026 and were told they had already updated software to address the oil consumption and we were told that should resolve the issue. On June 30, 2026, the truck was towed to the dealership after repeated stalling and a check engine light. The dealership again acknowledged this is a known issue with this engine - the valve seals are defective yet they had stalled our concerns so long at this point, we were past the warranty period. We researched and found this was a widespread, known issue asked whether Ford would offer customer loyalty assistance after 30 years of Ford ownership. We were told the truck's approximately 118,000 miles exceeded the assistance threshold. The engine replacement was quoted at $15,000. Ford advised us to repair the engine and save our receipt in case they should issue a recall at some point in the future. Given the value of the truck was $15,000 we chose not to keep investing in this vehicle and sold it for parts at a loss.

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.

I. Vehicle Purchase and Maintenance History In September 2020, I purchased this 2020 Ford F-150 new. II. Chronology of Defect and Repair Attempts Around 33,000 miles, the vehicle began exhibiting severe excessive oil consumption, an audible engine noise, and visible blue/gray smoke puffs emitting from the exhaust system. The following timeline outlines my exhaustive efforts to have Ford remedy this under warranty: • March 14, 2025 (36,370 miles): First formally reported the noise and exhaust smoke to Service Advisor Shelby Ray. The dealership initiated an official Ford Oil Consumption Test. I was instructed to drive 1,000-mile increments and return for unrecorded level checks. • May 21, 2025 (38,200 miles): Second formal report. The dealership performed Technical Service Bulletin (TSB) 192365 CP:6006, an established protocol recognizing inherent oil consumption flaws in this specific 5.0L engine. • August 7, 2025 – September 11, 2025 (41,119 miles): Third formal report. The vehicle was left at Tony Serra Ford for over a month (RO # 6034434) to perform engine repairs mandated by Ford tech lines. A loaner vehicle was provided. • December 9, 2025 (44,144 miles): Fourth formal report. The defect was noted as unresolved and still present between oil changes. The engine was found to be 2 quarts low on oil upon arrival. A new tech line case was opened. • May 7, 2026 – Present (48,086 miles): Fifth formal report. The engine noise and exhaust smoke. Truck has been at dealer for 3 months with no resolution.

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 shifts hard (ie: jerks, clunks) between 4-5 and 5-6 gears, and has on occasion failed to grab 1st gear when starting from a stop (revs, doesn't go). This occurred while turning across traffic, 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. Furthermore, I have already had two transmission rebuilds under warranty, and it's going back to the shop for a third time with the same issues 9/8/26. THE SAME ISSUES. I bought this truck in 2024 at 70K miles and it has been nothing but problems.
