2020 Ford F-150 complaints

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 from Ford Motor Company regarding the 21B10 program or its supplements. Safety Implication: The failure to apply the 21B10/21N08 updates directly contributed to the mechanical failure of the cam phasers and transmission. This resulted in the vehicle entering "Limp Mode" during highway operation, creating a severe risk of rear-end collisions due to the sudden loss of motive power. I request that these facts be added to my

Wiper blades are going very slow/failing like other model years/recalls.

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.

The contact’s father owns a 2020 Ford F-150. The contact stated that the check engine warning light was illuminated. While driving at various speeds and accelerating or while idling, the vehicle bucked or jerked. The vehicle failed to accelerate intermittently, causing the driver to make several attempts to restart the vehicle, depress the accelerator, and allow the engine to cool down for the vehicle to accelerate as needed. There was a loud grinding and knocking sound coming from the engine compartment. The vehicle was taken to the dealer, who diagnosed that the engine had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure, and a case was opened. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 55,000.

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 up the dealership for so long. Now it’s out of warranty and I’ve left looking at over $6500 to fix the cam phaser issue that they knew was bad and they didn’t recall them. So as of today, January 11, 2026 my truck has 41,000 miles on it. I have driven it less than 13,000 miles in five years. And I’m not looking forward to having to fix the transmission as well because it has a major issue and that should’ve been recalled as well. Ford is leaving us hanging out there with these trucks that cost over $50,000 and in the end it’s gonna cost us another 20 to 30,000 to fix them. Ford still hasn’t fixed the recall that is presently out as well for the sync and back up camera.

Front passenger door lock will not function. the lock does not lock or unlock with the key fob or the interior door lock controls.

The truck's cam phasers are rattling bad and getting worse. It used to only do it at initial start up in the morning and any time it sat for an hour or more , but now it seems to be rattling on every startup. Ford has newly designed cam phasers, but they are not offering to put those in unless I pay for it.

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.

Extremely loud electrical POP followed by loud static

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 ARE MUCH WORSE THAN JUST A TROUBLED TRANSMISSION SERIES. WHILE DRIVING TO THE POST OFFICE TODAY, IT WOULD NOT GO INTO REVERSE FOR SEVERAL SECONDS. ON THE WAY BACK FROM THE POST OFFICE, DRIVING ON THE ROAD, IT SHIFTED FROM ITS GEAR INTO A STEADY NEUTRAL ALL WHILE I WAS PRESSING ON THE ACCELERATOR CAUSING THE ENGINE TO REV AND WHEN IT FINALLY SLAMMED INTO THE NEXT GEAR, CAUSED THE TRUCK TO ROCKET FORWARD. IT QUICK ACCELERATION WITH THE NECK BREAKING JERK WAS DISTURBING.

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 a true recall mandated by NHTSA) had been performed by a TSB (along with the unintentional tailgate opening also a Customer Satisfaction Repair). There are no recalls issued on this vehicle. Ford has offered NO assistance towards repairs. As evidenced by the number of complaints filed on the NHTSA website for this particular engine, at what point will the NHTSA open an investigation and mandate that FORD issue a RECALL for the KNOWN problems with the R1080 3.5L and the camshaft/phasers.

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 a turbocharger failure caused total loss of engine oil without triggering any oil-pressure warning or driver alert, creating a risk of sudden engine failure, loss of power, or engine seizure while driving. The lack of oil-pressure warning before or during the event was confirmed by the dealer’s inspection.

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.

Ford doesn’t want the fix the problem because my vin number is not on the list. Yet, there have been recalls for 2020 Ford F-150s related to the emissions system, including a recall for the 2.7L EcoBoost engine's catalytic converters, which requires a Powertrain Control Module (PCM) reprogramming, and another related to a loose battery cable that could cause stalling, fire, and other malfunctions. Catalytic converter recall (24E12) Who is affected: 2018–2020 F-150 models with the 2.7L EcoBoost engine. : The recall addresses inaccuracies in the catalytic converters' effectiveness. The primary fix is reprogramming the PCM to more accurately detect issues, which might trigger a check engine light if the converter is faulty.

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 transmissions and should be recalled for repair &/or replacement by FORD. This truck has only 116,000 miles!!

The contact owns a 2020 Ford F-150. The contact received notification of NHTSA Campaign Number: 25V442000 (BACK OVER PREVENTION). However, the part to do the recall repair was not yet available. The contact stated that the rearview camera displayed a black screen or occasionally failed to activate while shifted into reverse(R). The failure obstructed the driver's visibility, which prevented the driver from safely operating the vehicle. A message to check the surrounding area was displayed on the instrument panel. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was approximately 91,000.

My rear back up camera all of a sudden does not have a clear view when backing up, the view is very grainy, and you cannot see anything behind you, Ford has recalled 1.4 million back up camera's and is tell me my truck is not affected, but the same year trucks are also affected by the recall.

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.

My camera went bad at 69000 mi, it does exactly as those recalled but I don't get a recall notice!! Camera needed as safety tool for me, as I am 81 years old, why do they go all around this year and model!! It does exactly as those recalled!! Spoke to ford several times but no results!! Help!!06

While driving, my 2020 Ford F-150 suddenly displayed a warning on the dashboard that read “Steering Assist Fault – Service Req’d.” Moments later, the truck completely lost power steering, and the steering wheel began to lock up while the vehicle was still in motion. I, (the owner of the vehicle), was able to muscle the steering wheel just enough to safely get us off the road and home. Had he not had the physical strength and experience to manage the vehicle manually, this could have resulted in a major accident or fatality. The truck was towed to Duval Ford on October 13, 2025, where it was diagnosed as needing an electronic power steering rack replacement, with a total repair estimate of $4,049.70. The vehicle is not under warranty, and Ford has informed us there is no recall currently associated with this issue. This is a critical safety failure of a steering system and should not be happening at any mileage. We are reporting this incident to request a formal NHTSA investigation into this issue, as it could easily lead to severe injuries or death in other cases.

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.

The contact owns a 2020 Ford F-150. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate as intended and jolted. The contact stated that the failure occurred while driving between the second and the third gears. Additionally, the contact noticed that the vehicle made unusual sounds while shifting into gears. No warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The contact was advised to contact the NHTSA Hotline to report the safety failure. The failure mileage was approximately 65,000.

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.

Windshield wipers not working properly. Wipers barely move, then seize up. No warning. Requires manual help/ movement by hand to get them to return to the bottom of windscreen. Was pouring rain and could not see out of windshield on the highway. I have not taken the vehicle to service yet - but this appears to be a widespread complaint when researching the issue online.

Failed CDF drum and collapsed shift solenoid retainers. Causing erratic shifting, hard shifting, gear skipping, bouncing back and forth between gears, delayed gear engagement, and shuttering when shifting.

I brought my 2020 F-150 XLT to Cook Ford Texas City for a recall (24E12 PM reprogramming) and a steering issue that have happened while driving and making me loose control, almost hitting the vehicle front! After spending over $3,400 to get the whole steering system changed, I picked up my truck thinking everything was good. Within one day of the recall being done, my check engine light came on with an emissions fault. When I asked about it, I was told this was "normal" after the recall because now the PCM is able to read codes. But it feels shady that a brand-new problem shows up immediately after a recall reprogramming. Now, I'm being told I might have to pay for even more expensive repairs like a catalytic converter (5k for both) - right after just spending thousands. It's frustrating, stressful, and feels like a never-ending cycle. After looking online, I found many other Ford owners sharing the same experience with this recall on forums like Reddit. That makes me believe this is not an isolated case.

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 by Ford has occurred to date. Warning Indicators: No warning lights, check engine lights, or dashboard messages appeared prior to or during the failure. The only symptoms were the physical driving symptoms described above—harsh shifting, significant lag, and abrupt gear engagement—which began approximately gradually over the past month and progressively worsened until the vehicle became u

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 exhibited rough shifting behavior on the short drive home. A friend pulled codes from the TCM/ECU and found P0734-00, P07F7-00, and P2535-00. He assisted, backed up the ECU/TCM, re-flashed the onboard ECU/TCM with the latest mappings, and reset the adaptive learning. He then drove the vehicle with diagnostics equipment connected and recorded the driving data, finding that the transmission was losing pressure and the shift behavior was slightly better but still rough shifts between 2-4 and 7-8 gear. Once the drive/test was completed, codes P0761 and P2702 appeared on the reader. He explained that the

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.

This model year truck has an oil consumption problem. I had the truck repaired under the Ford bulletin, but I’ll still need an oil consumption test after 1000 miles and continued frequent oil changes.

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 one month after the warranty expired. The dealer quoted me approximately $7,000 to repair it. I have read that Ford has replaced the old pressed bushings in this part with welded ones to prevent this failure, which suggests this may be a known defect in the original design.

Cam Phaser failure causing the engine to knock and eventually lose power. Cost $4,900 out of my pocket to fix with 64,000 miles on the truck. Reading online forums, this is one of the MOST common issues with 2018-2022 3.5 and 5.0 f150s. The vehicle has a history prior to my ownership of this same issue. Check engine light is triggered when you hear the engine rattle and throws codes for Camshaft position error. Ford dealer replaced every sensor and harness on the truck before decided the cam phasers were bad, adding another $4,900 to my $2,600 bill. This was during my ownership of the truck between 63,000 and 65,000. First two thousand miles of ownership. Vehicle would stall at low rpm’s after highway use, stalling the vehicle while rolling into an intersection.

The transmission in my 2020 Ford F-150 (10-speed automatic) has exhibited ongoing and dangerous shifting issues. While driving at normal speeds, the transmission frequently shifts hard between gears, surges, or delays engagement, especially between 2nd and 4th gear. On multiple occasions, the vehicle has jerked violently when slowing to a stop or accelerating from a red light. There have also been sudden RPM spikes and power loss without warning. The issue began around July 2025 [125,000 miles] and has continued. The safety of myself and others has been at risk due to the vehicle lunging forward at unpredictable times. This behavior has made it unsafe to merge into traffic or stop smoothly. No warning lamps have appeared, but the problem is reproducible. I believe this may be related to ongoing class actions regarding Ford’s 10R80 transmission. The issue has not been fully addressed by Ford, despite similar complaints from other owners.
