general problems of the 2020 Ford F-350 - part 1

Driving the vehicle at highway speeds (around 55mph). Driver hear a loud hum, lost power and needed to pull over. The rear axle housing grenaded and twisted the pinion clean off the rear axle. The truck was loaded with tools and pulling a trailer. However this load was well within the gvwr of the vehicle.

Truck started jerking and shifting hard when driving. Contacted Ford and they said that they needed to do a software update. Did the software update and it got extremely worse not wanting to shift into gear. Take the truck to Ford in November to have fixed said I needed a new tranny. My extended warranty approves a used one they put it in same thing happening. Send that one back and put another one in same issue with that tranny. It is now March and they cant find another used tranny to fix my truck. After reading many things online it comes down to the cdf drum the bushing/sleeve moves inside the drum. Ford is aware of this issue and has upgraded/revised a drum. Why is this not a recall issue?.

Transmission jerking hard down shift cause stalling did update less then 100k miles on truck and now back doing it again.

Our 2020 Ford F-350 experienced a catastrophic mechanical failure while in motion. The driveline disconnected, the rear axle locked up, and the transmission bellhousing was destroyed—leaving the truck completely immobile and blocking traffic. This occurred with no prior warning and posed a significant crash risk. At the time, Ford safety recall 22s22 (related to a known defect in the transmission’s output planetary four assembly) was open and had not yet been completed. The symptoms and failure we experienced match the failure scenario described in Ford's own bulletin for 22s22: driveline separation, internal transmission damage, and loss of control or park function. Ford has denied coverage, stating the failure was due to a "loose pinion flange nut" and unrelated to the recall. However, they have not provided any inspection documentation, photos, or evidence that the recalled components were properly inspected or ruled out as the root cause. We have repeatedly requested this documentation from both Ford and the dealership, but neither has provided it. We are concerned that the failure was caused by the exact defect identified in recall 22s22, and that Ford is failing to take responsibility or follow full recall procedures—including post-failure inspection and transparency. We are requesting that NHTSA investigate this case as a potential mishandling of a known safety defect and failure to comply with recall responsibilities.

Transmission lunges forward or reverse when placed into gear from park. Transmission fails to shift or hard shifts while moving through low range. Shifting is soft or prolonged in some higher range with a noticeable lag.

This is a supplemental complaint to odi number 11730675 filed on April 16 2026. I am adding the following critical information: I am filing this complaint in relation to Ford's NHTSA consent order regarding recall compliance. My 2020 F-350 VIN [xxx] was built at kentucky truck plant in March 2020 — within the exact production window of safety recall 22s22. My transmission has failed with the exact defect mechanism described in 22s22. My VIN was excluded from the recall fsa list despite matching build date, plant, and identical failure mode. I am requesting this complaint be reviewed in the context of Ford's consent order obligations regarding proper recall scope. Ford customer care case number: xxx-xxx.

I have been experiencing issues with my transmission. I took the truck to the Ford dealership in poteau, oklahoma. I was informed the vehicle was having the same issues as the transmissions that were on a recall list, yet my VIN number was not one on the list. I did receive a recall notice from Ford in 2022 timeframe, but was not having issues at the time I receive the notice. On August 15, 2024, I contacted Ford headquarters and was told. . . "your vehicle does indeed fit the criteria of the affected vehicles, but your VIN number is not on the list of the affected vehicles. We cannot tell you why your vehicle is not on that list, but I would suggested that you contact (NHTSA) and ask for your VIN be added to the list. I recommend you do that as soon as we hang up. " the moment I ended the call with Ford headquarters, I contact a representative with (NHTSA) as recommended. The representative stated the first step, to file a claim. So thats where im at now. I would like to ask that my VIN number be added to the list of recalls on the document attached, seeing my truck fits all aspects of the current recall.

Ford 10r140 transmission issues: transmission has harsh engagement, clunks and slams into gear. Transmission gets stuck in between gears while in motion at all speeds while driving on city streets or on the freeway.

I am the owner of a 2020 Ford f?350 equipped with the 6. 7l power stroke diesel engine. My vehicle is subject to an open safety recall, NHTSA 24v957, involving the high?pressure fuel system. I have been informed by an authorized Ford dealer that there is currently no effective repair remedy available. While I have not experienced loss of power, my vehicle has exhibited abnormal transmission shifting behavior beginning around 40,000 miles. This concern was documented by the dealer and described as normal operation. The condition persisted and was documented again around 60,000 miles, although the dealer stated they could not replicate the issue. Given the unresolved safety recall and ongoing powertrain behavior, I am concerned about vehicle safety, drivability, and long?term reliability, and I am submitting this complaint to document the risk before a safety?related failure occurs.

I own a 2020 Ford F-350 super duty (VIN: [xxx] , mileage: ~20,000). The vehicle is subject to a recall involving the transmission output planetary four assembly replacement. Ford and the dealer insist that the transmission must be disassembled and rebuilt to complete this recall. I do not agree with this solution because it permanently alters the integrity of the original transmission. Additionally, the dealer (route 23 auto mall, butler NJ) has repeatedly mishandled repairs, including installing the fuel filter incorrectly multiple times. I have opened several case numbers with Ford customer service: recall case [xxx](02/02/2024) fuel filter dealer error: [xxx] (01/06/2025), [xxx] (01/15/2025), [xxx] (08/26/2025) transmission recall follow-[xxx] (02/25/2025) buyback case (denied): [xxx] (03/04/2025) despite multiple cases, Ford refused to buy back the vehicle because it is registered under a company name. This is unfair and leaves me with a defective and unsafe vehicle. I request NHTSA to investigate this recall and require Ford to provide a new transmission replacement instead of a rebuild, and to review Ford’s handling of dealer errors and warranty obligations.

This letter stated trucks built in the kentucky truck assembly plant between October 1, 2019 through September 21, 2020 the 10r140 transmission the pinion thrust washers can disintegrate with a defected part. Per the VIN number my truck was built at the above kentucky plant on February 20, 2020 with this 10r140 transmission. My truck is built with a 6. 2 l gas engine with the 10r140 transmission f350 super duty. The service tech said this is the same transmission put in the diesel engine trucks.

My 2020 Ford F-350 has had an occasional problem with the transmission since shortly after I purchased it. It started with sticking in gear occasionally to the point where the engine rpm's would stay very high but not shift even when pushing the accelerator even more. It just would not come out of it. The dealer didn't find any issue and the issue subsided a bit, but in the last 6-8 months, it has noticeably shifted hard into drive, but not when shifting into reverse. Putting it in drive even with the brake depressed hard to the floor, it jolts forward and shakes the entire truck. When downshifting, it sometimes does it so hard that it feels like a vehicle hit the rear of the truck. There is nothing smooth about this truck with the behavior this transmission is showing. I changed the fluid and filter 6 weeks ago and it's the same. It also occasionally revs up when accelerating as you turn a corner and it "catches. " I am mostly a daily driver that occasionally tows a boat or snowmobile trailer. Non-commercial user.
