2020 FORD F-150 Power Train Problems

2020 F150 with only 63000 miles has a failed transmission. The truck doesn't shift gears properly, gets stuck in gears, loses power suddenly. This is a huge safety risk as the vehicle just stops accelerating or working when driving. This clearly endangers me and other drivers. Ford refuses to pay even though their check engine light gave a TRANSMISSION/POWER FAILURE alert and the Ford dealership inspected it and their diagnosis is: REPLACE COMPLETE TRANSMISSION ASSEMBLY. HAS INTERNAL CDF DRUM BUSHING FAILURE. This is an ongoing issue with these 10 speed transmissions on these F150s. There are several class action lawsuits against Ford over these 10R80 transmissions. Ford is not only refusing to recall these dangerous vehicles but also refusing to pay to cover the repairs on transmissions they've known are defect.

I bought a 2020 Ford F150 XL with 83,000 miles on 27 JAN 2026 from a local Phil long Kia dealership. I started to notice that the shifting was very harsh immediately after buying the truck and that the transmission was dropping the gear when I was driving at stoplights and even when I was entering an intersection almost causing an accident. I notice the issue more at slow speeds and in lower gears. Today is 19 FEB 2026. I brought the truck to a local ford dealership and they told me that the transmission needs to be replaced.

While driving my F-150 I made a turn and when I went to accelerate again, the truck acted like it was in neutral - would not go. Engine continued to run but would not accelerate. A second car was directly behind me and almost rear-ended me when truck failed to move. Pulled over, tried low gear and reverse and nothing happened. Transmission is shot. Currently in for a rebuild. This is the Ford 10-speed trans, which has been known to fail. I only have 33,000 miles on the vehicle. Could've been much more dangerous had I been on the freeway when it failed.

The vehicle transmission is slamming when the vehicle decelerates. I can feel the jerking in the vehicle. I am concerned the transmission will fail while operating the vehicle resulting in a crash. This is the second time I have had this issue. It was repaired once by the Ford dealership. The vehicle has not been inspected by anyone for this occurrence. It has in the past for the same occurrence. There were no warnings prior to the occurrence. This is the second occurrence in several years. The current occurrence began on February 16, 2026.

Transmission downshifted on the interstate and overheated. Wouldn’t go back in to gear. Was in the passing lane and ended in an accident.

While driving the truck automatically down shifted. If I drove move 20 MP it would shift. The truck would not go into reverse, the gear was stuck. I had to turn if off and then turn it back on then It let me shift the gears. On the dashboard the wrench and other indicators lit up on the dashboard.

The Ford 10 speed transmission has continued to give me issues. Delayed shifting, harsh engagements, and overheating are the symptoms. I have been to the dealer several times for the issue. They programmed the transmission, reset values, then replaced the valve body. After valve body replacement, the service manager at the dealership told me that it shifts fairly well compared to other f150s and there’s nothing more they can do. There have been several instances where I have to pull over in traffic due to overheating. The lack of predictability in the shift also makes for unsafe situations.

First incident my [XXX] daughter was driving my truck on the highway going 70mph, the truck went from 10th gear dropped all the down to first almost causing her to wreck the truck before getting to the side of the road, it has a lifetime warranty so took the truck to Jones Ford in Wickenburg Arizona, after several conversations with the warranty company wanting to deny the claim finally got the transmission warranty and was told they replaced the transmission, this truck still was not driving properly not shifting gears , dropping gears at high rate of speed, back to the dealership, they did some computer updates, picked the truck up drove still not right, decided to take it to a different deal shop Camelback Ford in Phoenix Arizona, they replace transmission again, this is at least 4-5 transmissions in this truck, The truck still is not driving properly it’s...

Vehicle was purchased certified pre-owned from dealer at around 35k miles. Currently around 65k miles. Complete loss of power at 45 miles an hour. Truck shifted from 7th gear to 1st in a split second and brought the truck to a complete stop. Luckily able to pull onto shoulder to avoid getting rear ended from car behind. Decent maintenance records with dealer, no prior issues with transmission other than some rough shifting before this issue. Vehicle was dropped at dealer on 2-5-26, have not received any type of feedback or updated since dated 2-8-26. I know there is a current TSB on these transmissions, I believe they are defective based on other reports and my personal experience. Complete safety danger, 45 to 0 in under 2 seconds.

We’ve had this 2020 f150 since it was brand new with multiple Ford dealerships diagnosing and Test driving our complaints from the beginning. Only to hear “ we couldn’t get it to do anything and no hard shifting” countless times. Took to dealerships in Florida, Texas and other states with same same response to only refash the control module, which later was a recall on the valve body in the transmission. That did not change anything and now we are 59k miles past our warranty date with the exact same issues from day 1. They should stand behind their product and will not be buying another f150 only to have the same issues and no point in having a warranty if nothing was ever done to have a resolution to our problem -hard shifting while going from 3rd-4th gear a 4th to 5th -same thing while downshifting while applying the...

Transmission hard shifts. Up and down. At times hard enough that passengers feel this. Concern is how does this affect the life and safety of the vehicle. Ford claims no issues.

Vehicle failed to shift properly while making multiple left and right turns from a stop (for the record, the vehicle also had shifting problems at other times). This resulted in the vehicle hesitating while entering traffic. Multiple times other vehicles had to beep horns and brake emergently. One time an 18 wheeler almost tboned me while I had my 2 year old some in the back seat. Definitely a safety issue that almost cost my son his life.

Transmission shifts hard looses power. I reported it to ford before my warrenty ran out. They said it was fine and just needed an update. It did not fix it took it and got second opinion and the transmission was bad and needed to be replaced. I had to pay out of pocket because they did not take care of the issue while it was under warrenty. Now im out 7000 because of a faulty transmission and Fords lack of addressing the issue

2020 f150 down shift when in drive mode.it has this really hard jerk when I'm taking off from a stop light or stop sign even when stopping for a traffic light.

Transmission erratic shifting causes unsafe vehicle handling characteristics. Vehicle will not properly accelerate under certain circumstances. Occasionally in parking lots, vehicle will accelerate on its own after throttle is released under certain conditions. Transmission has been replaced several times, and issue persists in all units. Problems are reported in TSB’s sent out by dealerships.

Transmission (10r80) down shifts hard and shifts hard between 3-4 and 7-8 gears. And front differential makes a noise.

While driving my 2020 Ford F-150 on the highway, the transmission suddenly failed, causing loss of normal drivability and creating an immediate safety concern due to reduced vehicle control at highway speeds. The failure involved the transmission system, which I later learned may be related to Ford’s recall notice stating that the installed remanufactured transmission may be missing an internal bearing. Prior to the complete failure, the vehicle exhibited symptoms consistent with the recall, including harsh shifting, shuddering, and vibration. These symptoms escalated until the transmission malfunctioned to the point the vehicle was no longer safely operable, requiring me to tow the truck to Rocklin Transmission. The transmission was replaced out of pocket by that independent service center, and the failed component should be available for inspection upon request through that facility. The malfunction created a serious safety risk because the transmission could become stuck in certain gears, illuminate the...

The transmission exhibits violent, harsh shifting, sudden and unpredictable deceleration, and most alarmingly, abrupt downshifting from 10th gear to 1st gear while driving at highway speeds. This is not a minor drivability issue — it is a severe safety defect that places my life, my passengers, and other drivers at risk.

Truck would downshift so hard it would squeak tires. Took to dealer they replaced transmission saying the drum comes loose inside and oil passages do not line up. This year should be part of your investigation

I am writing to provide supplemental information regarding my existing safety complaints (IDs XXXand XXX). This update concerns a documented failure by Ford’s authorized dealer network to perform mandated Customer Satisfaction Programs (CSPs) that directly correlate to the catastrophic powertrain failures I have experienced. Timeline and Documentation of Failure: • August & September 2025: As previously reported, my vehicle suffered sudden "Reduced Power" malfunctions while in motion (P0734/P07F7), leading to a full transmission replacement. Discovery of Non-Disclosure: My records now confirm that on November 11, 2022—just weeks before I purchased this vehicle as a Ford Blue Advantage Gold Certified unit—CrossRoads Ford (Dunn, NC) documented that 21N03 (Cam Phasers), 21N08 (PCM Reprogram), and 21M06 (Tailgate) were outstanding. • Breach of Duty: Despite this knowledge, the dealership sold me the vehicle on December 3, 2022, without completing these safety-related service actions. Furthermore, as the registered owner, I never received the required notification...

transmission unexpectedly downshifting to first gear at speed. It sounds like shift cable locking clip problem.

The contact owns a 2020 Ford F-150. The contact stated that while driving at various speeds and attempting to shift into third gear, the vehicle started shaking abnormally, and the gear shift was difficult to engage, causing the transmission to shift hard. The contact stated that at faster speeds, while attempting to shift into seventh gear, there was a delayed response. The powertrain fault warning light was illuminated. A dealer was contacted. The vehicle was taken to the dealer where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The contact related the failure to Technical Service Bulletin: 23-2123 (Harsh/Delayed Engagement And/or Harsh/Delayed Shift); however, the VIN was not included in the TSB. The manufacturer was not notified of the failure. The failure mileage was 117,000.

The contact owns a 2020 Ford F-150. The contact stated while driving from a complete stop, the vehicle went into LIMP Mode and failed to accelerate as intended. After a while, the vehicle accelerated, but the acceleration was delayed. The wrench warning light illuminated, and the contact received a notification from the Ford App with the message “Powertrain Power Reduced”. The contact drove the vehicle to a dealer, where it was diagnosed that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 49,244.

My truck is a 2020 F150 3.5 eco-boost four-wheel-drive, 41,000 miles I’ve owned the truck since November 20th 2021, the mileage at time of purchase was 28,211. Less than 30 days later I had taken it to the Ford dealership to have the IWE’s replaced and wheel bearings, which is the four-wheel-drive locking hub assembly. It took them over six months to fix it. Now, December 1, 2025 the same problem has returned the IWE’s have failed, when they fail metal shavings goes into the wheel bearings. Mind you this is less than 13,000 miles since the first repair. Upon picking my truck up from Ford on a Friday afternoon at 5 PM, January 9, 2026. Upon start up now, my cam phases are rattling.. I even asked Ford. I lost over seven months of driving my pick up and not being able to use my warranty because it’s set...

10 speed transmission, started slipping. And then slamming into gear while it would down shift. We have had 4 rebuilt transmissions put in with Ford. And now the truck just went into the shop again for the same issues. This last time before going into the dealership, felt like the transmission was just going to drop out. It was hard.Do not feel safe in this truck any more. it is not reliable. No warning lights at all.

10 speed TREMIC transmission, the same one covered by NHTSA #24V-208. Transmission hunts for gears, and has dropped from a high gear to first gear without warning. The advisory says that it could drop out of any gear to first gear without warning possibly causing a crash. For some reason, my vehicle with the same transmission and same problems is not covered by the recall.

Vehicle is showing symptoms similar to common reported problems from people who owned Ford F-150 with Eco-boost. Symptoms such as: Engine had difficulty starting Transmission shifting Rattling noises coming out from the engine compartment Oil leaks coming out the tail pipe Gauge is showing engine is over heating Turbo is having a hard time accelerating

The transmission has Harsh, Jerky, clunking shifts. It also has delayed engagement and complete power loss. There is also problems with downshifting from 7th gear to first gear when coming to a complete stop. Vehicle seams to be in neutral then finally shifts to 1st gear before vehicle finally moves.

Transmission shifted from 10th gear to 1st gear at highway speed. Transmission was rebuilt by ford, and is again exhibiting poor/harsh shifting.

Transmission is stalling, jerking, skipping gears and slipping. I have talked to the dealership several times about the transmission slamming really hard in 4th and 8th gear. They would tell me it’s just trying to find the right gear to be in, your battery is causing it or it needs to be reprogrammed. There has never been any warning lights. This truck has spent over 4 months in the shop for drive train issues. New rear end, new drive shaft and a vibration that has never gone away.

I HAVE OWNED THIS TRUCK AT AROUND 38000 MILES UNTIL NOW AT ~63,000 MILES. I HAVE COMPLAINED TO THE DEALERSHIP I PURCHASED THE TRUCK ABOUT THE TRANSMISSION BEING UNPREDICTABLE. AT AROUND 50,000 MILES I BROUGHT IT TO THE DEALERSHIP FOR SHIFTING POORLY, NOT SHIFTING INTO GEAR, JUMPING GEARS. THEY LOOKED AT IT, SAID IT HAD A PROBLEM WITH THE TRANSFER CASE BUT NOT THE TRANSMISSION. THEY REPLACED A COUPLE PARTS. THE TRANSMISSION PROBLEM HAS NOT GONE AWAY. I CALLED AT AROUND 59,000 MILES ABOUT SERIOUS ISSUES WITH THE TRANSMISSION NOT GOING INTO GEAR AND JUMPING GEARS CAUSING THE ENGINE TO REV. BY THE TIME I BROUGHT IT WITH THEIR SCHEDULE, MY 60,000 MILE WARRANTY HAD RAN OUT. I'M NOW AT 63,000 MILES, THE TRANSMISSION IS WORSE THAN EVER, AND FORD WILL NOT WARRANTY THE PROBLEM. THE DEALERSHIP BLAIMS THE 10 GEAR TRANSMISSION WITH HOW IT IS ACTING, BUT MY ISSUES...

I had just replaced the transmission (R1080; 6 cyl 3.5L Turbo) on September 3, 2025 due to P0734-00 (Gear 4 incorrect Ratio and P07F7-00 (Gear 10 incorrect Ratio). The transmission matter can be referenced on NHTSA ID # XXX. On September 30, 2025, while driving down the parking deck ramp (at 3-5mph) my check engine light came on with code P0022 (camshaft timing); resulting in replacement of the camshafts. The camshaft had a HOLE in it (photo supplied). The camshaft issue is another issue many Ford F150 truck owners are experiencing. Again, Ford has continued to give "band-aid" fixes with TSB's and no REAL fix to a continuing issue with these trucks. On December 3, 2022, this used truck was purchased from a Ford Dealership in Raleigh, NC (77,100 miles) and was Ford Gold/Blue Certified per my purchase information. The Gold/Blue paperwork even included that the "Customer Satisfaction Repair" (not...

Three separate times vehicle shuttering and jerked, and wouldn’t engage into certain gears left my son and I stranded on the freeway. Unable to drive, it started and drove fine hours later after it cooled. Weeks after this happened leaking fluid, overheating, and unable to shift into gear. Shop said it fried 3 gears. Currently having to replace the entire trans which costs half of what the vehicle is worth.

While driving at normal speed, the vehicle suddenly began producing heavy white smoke from the exhaust, the engine started to idle roughly, and a check-engine light came on. There was no oil-pressure warning, no low-oil message, and no “stop safely” alert of any kind. The only warning was emissions-related. After seeing the smoke, the vehicle was parked and later driven only to a dealer for inspection. A dealer inspected the vehicle and confirmed that an internal seal in one of the turbochargers failed, causing the engine to pump all of its oil directly into the exhaust system. This resulted in complete oil loss and catastrophic engine damage due to oil starvation. The dealer confirmed the failure and determined that the issue originated from the turbocharger assembly and not from misuse or neglect. The failure occurred suddenly and without any oil-pressure warning to alert the driver. The safety concern is that...

Transmission failed. Pulling into traffic the transmission failed to shift from first gear into second, instead not going into any gear at all, putting my entire family at risk of being struck by oncoming traffic! Engine revved and truck would not move. Then suddenly shifts into third gear jerking violently. Currently in shop for transmission replacement. After a bit of research I found that this is a common issue with the transmission.

The transmission has the potential to shift erratically most recently when crossing a divided highway, trying to get in them median, the truck switched gears, causing the truck to stop blocking oncoming traffic. It was only momentarily and shifted back to the correct gear. It has the potential to hard shift pretty consistently.

The contact owns a 2020 Ford F-150. The contact stated that while driving 70 MPH on the interstate, while depressing the accelerator pedal, the vehicle decelerated to 2 MPH. The messages to “Schedule Maintenance” and “Powertrain - Reduced Power” were displayed on the instrument panel and the Mobile App on the cellphone, and the vehicle went into LIMP Mode. The contact pulled over to the right side of the road and researched the failure. A dealer was contacted. The vehicle was taken to a dealer to be diagnosed. The vehicle was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and stated that the dealer would be contacted, and then the contact would receive a callback. The approximate failure mileage was 46,000.

Once the vehicle is in Drive and starts shifting through the gears, the truck losses all acceleration for 3-5 seconds and then experiences a harsh shift into gear. This causes the vehicle to "stall" in intersections and other hazardous locations if it does not shift properly. The 2020 F150 3.5 ecoBoost has been serviced at local Ford dealerships since bought. Most recently, it was taken into a Ford dealership for routine oil change, transmission fluid change, spark plugs and coils, and 100K inspection due to the vehicle being at 94K miles. I advised the service technician of the concern for the shifting issue that started between the last oil change, which got significantly worse during day-to-day operation.

10rd80 Transmission CDF drum failure. A known design defect on 2020 F150 that Ford should issue a recall on. Ford finally fixed the design issue in August 2022. My truck is out of warranty so I will be out over $6000 that I do not have to fix. Extreme financial problem as I do not have the money to fix and this is my only vehicle

Transmission will not shift into gear. No recall on this and dealers option is for service and repair. Transmission was serviced and problem shifting still continues. I have received alerts from Ford Pass App indicating Powertrain Malfunction/ Reduced Power — What Is Happening? The transmission control module has detected a concern when trying to shift to 7th gear. A failsafe logic disables 7th gear for the remainder of this key cycle. What Should I Do? Have your vehicle checked by an authorized dealer as soon as possible. This loss of power is a huge safety issue as when I accelerate into traffic the lag in shifting causes the truck to not get up to speed and you’re basically a sitting duck. Transmission was serviced and this did not resolve the issues. Replacement is now scheduled and will cost a minimum of $9000.00. This is a KNOWN issue with the 10-speed...

The transmission progressively became worse--skipping gears, lurching, clanking, hesitating and losing power. It became unsafe to drive. A complete rebuild of the transmission we required. There is a defect int he transmission that allows bushing/rings to move around.

Truck was traveling at 30 mph and slowing down for stop sign and shifted from 4 th gear to 3rd gear so hard the trucks engine turned off and had to come to a stop and shift into park to turn truck off and back on again. Truck was traveling at 30 mph and slowing down for stop sign

At around 61,000 miles my transmission started having a shuttering noise and had a harsh jerky shift from 3rd to 5th when vehicle was recently started up for the first time of the day. multiple TSB's on Ford's website for this issue including the latest TSB 25-2301. It appears that the interior drum has failed which has been a known issue. Dealer states $6219.87 to repair the transmission. CDF TSB, replace the valve body, and reprogram the PCM.

While driving on the interstate doing around 70 MPH I I Stanton drive up a fairly steep hill on the road . About half way up the truck down shifted from 10th gear too what it said was 7th. The gear did not engage and the truck revved up like it was in neutral. I pulled over immediately. Checked under the truck and no leaks. Got back in and truck ran like normal. Went to the dealer and was told that is a common issue with this particular transmission. I also have noticed when driving and coasting too a stop when the truck downshifts there is sometimes a loud clunking sound. Ford needs to be help responsible for putting trash transmissions in these vehicles. Please advise them to issue a recall and repair or replace them.

Component/System Failure: The 10-speed automatic transmission failed prematurely at only 75,000 miles. The transmission is still in the vehicle and available for inspection upon request. The symptoms include harsh shifting between gears, particularly into lower gears, followed by significant lag and then abrupt jumping/engagement. This is consistent with numerous other complaints filed regarding the 10-speed transmission in this model year. Safety Risk: The unpredictable transmission behavior created dangerous driving conditions. The harsh shifting and lag followed by sudden acceleration made it impossible to safely merge into traffic, navigate intersections, or maintain consistent speed on highways. The erratic gear engagement put myself, my passengers, and other drivers at risk as the vehicle's response became completely unreliable. The truck is currently unsafe to drive. Professional Confirmation: Yes, the problem has been confirmed by Aamco Transmission on Sept 17, 2025. They diagnosed it as transmission failure requiring complete replacement. Manufacturer/Other Inspection: No inspection...

I was driving eastbound on city streets at 30 mph with my three young children when the vehicle exhibited abnormal shifting behavior, searching for a gear. Despite being in 9th gear, traveling the speed limit, and lightly pressing the pedal, the vehicle experienced a rough downshift and lost power while going up a small incline over a freeway overpass. I turned on my hazards and attempted to move over to avoid an accident, which I successfully did. The vehicle regained power after restarting with rough shifts in the lower gears. I put the vehicle in manual mode to better control the shifting, though it remained incredibly rough. The kids were shaken and refuse to drive in the vehicle. Since then, I’ve only driven it to have it serviced at our local Ford dealer. They stated everything was fine after the transmission fluid exchange and battery replacement. However, the vehicle still...

Like most people with the same model and year. My transmission stopped shifting, and stalled. I was fortunate since I was sitting in the intersection. You need to look into the 10speed transmission they are faulty and need to be investigated!

Like a lot of f-150 owners, my 10speed transmission stopped working not allowing me to accelerate or shift into reverse. I was stuck in the intersection luckily I didn’t get into an accident. The truck was stuck in 7th gear! This is dangerous and happens far too commonly, please investigate, this is dangerous and expensive for the average consumer. Please help.

the transmission for this truck has on several occasions shifted very hard when accelerating, and on a couple occasions has down shifted without warning and without reason. the down shifting incidents were unexpected and could have caused an accident if I was in traffic.

The transmission failed. While driving, it shifts extremely hard and will suddenly downshift without warning. Autonation Ford of North Canton, Ohio, inspected the vehicle on August 13, 2025, and reported that the CDF drum clutches were likely worn. The truck is available for inspection upon request. The sudden downshifts cause the truck to jerk violently and lose speed abruptly. On multiple occasions, this has nearly caused me to lose control and creates a high risk of being rear-ended by other drivers who are not expecting the sudden slowdown. Yes. Autonation Ford of North Canton, Ohio, confirmed the issue on August 13, 2025. Yes. Autonation Ford of North Canton inspected the transmission and stated it was likely due to worn CDF drum clutches. There were no warning lamps or messages. The symptoms began before August 2025 when the transmission started slipping, shifting hard, and then downshifting unexpectedly. The issue occurred just...
