2020 Ford F-150

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.

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.

Harsh shifting from 3rd to 4th and 7th to 8th

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 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.

When driving the vehicle it randomly jumps gears, when taking off it went into limp mode today. My wife almost got slammed by a semi truck! I called ford and they are not interested in hearing my case only wanting me to pay these outrageous fees. The pcm recall fix did not fix the gears jumping

While driving I will get a wrench symbol with a bunch of codes pop up u0121:00:28 u0131:00:28 u0137:00:28 u0164:00:28 u0199:00:28 u0200:00:28 u0212:00:28 u0252:00:28 u0256:00:28 u1012:00:28 p0557:00:28 p1935:00:68 p193e:00:28 I have also had it jerk while driving ( went down into first gear) while having no power to my gauge cluster ac nothing

Severe transmission shifting delays, unresponsive when accelerating. Shutters and skips when coming to a stop.

Transmission shifts from a higher gear to 1st when going over 60, also transmission has a hard time shifting skips 2nd, 4th, and sometimes 6th gear.

Went to speed up as I was approaching a ramp going uphill and almost towards the top the truck decided to down shift to first gear going about 45 mph. No accident occurred as no one was around me.

MY PICKUP HAS THE 10R80 TRANSMISSION. IT CURRENTLY SLIPS IN LOWER GEARS AND SOMETIMES NO 10TH GEAR

Harsh shifting in between gears. Jerky shifting and shudders while shifting as well

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.

Truck equipped with the 10R80 downshifted from 10th gear to 1st gear while on the freeway doing 80mph. NOT SAFE AT ALL.

There has been harsh shifting observed, both cold and warm. Often when downshifting and slowing to a turn or stop, there is a violent slamming into gear. I have also observed slipping in 3rd gear and making harsh shifts that appear to skip gears by the indicator. This is not a constant but intermittent issue. I have not taken it to the dealership because they will likely not be able to duplicate it in a reasonable amount of time.

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!!!

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.

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.

Camshaft had to be replaced a couple years ago, followed by cam shaft sensor. Then another $6,300 of "critical" issu3s to be fixed. The vehicle is 5 1/2 y/o. Absolutely ridiculous that this amount of money is required for such a young vehicle.

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
