general problems of the 2021 Ford F-150 - part 2

Transmission downshifted while driving at speed causing wheels to lock up.

10 speed transmission jumps at highway speeds, clunks when stopping, and slips when cold. I've had it to the dealer and they replaced the torque converter, and I've had it back several more times. The garage refuses to allow another appointment since Ford engineers say the slipping and jumping is within specs and since no lights or warnings are noted I just have to live with it. The mechanics can feel it but are helpless to do anything about it. Ford refuses to fix it and it is a well-known problem.

I had my 2021 F-150 into the local Ford dealership not even a year ago due to a shifting issue. I was on the interstate and passing a car in the passing lane on the interstate and my truck shifted so hard I thought I lost something and then kinds lost power for a minute. The dealership ran a test on it, and it failed. It was some type of valve that was bad I guess Ford and gm are having the issue. Now I am starting to have the same issue on now it is down around 4th to 3rd or 3rd to 2nd gear, but when it shifts once in a while it is a very hard shift and it scares the hell out of you. Now once in a while when I go to shift from drive to park or drive to reverse the shifter will not move. Like I said I am getting ready to get ahold of the dealership again and get it in to be looked at I am just waiting for winter to be over.

Ford has refused, on multiple occasions and at multiple dealerships, to address the NHTSA recall number 23v896 (mfg. Recall number 23s65) issue with the wheel end hub bolt in the rear axle. Well, this weekend, the bolt on the passenger side rear axle broke off, rendering the vehicle undriveable. I brought it in to the lithia Ford dealership (who's online information said they were open) to get it addressed. They were closed, no one was there, and they won't even give me a loaner vehicle while the F-150 is inoperable. This recall has been out for two years now and they still won't deal with it. Absolute neglect of their obligations and an unsafe practice!.

The contact owns a 2021 Ford F-150. The contact received notifications of NHTSA campaign numbers: 23v896000 (power train), 25v455000 (fuel system, gasoline), and 25v729000 (visibility). The dealer was contacted. However, parts to do the recall repairs were not yet available. The manufacturer was contacted; however, the phone call was dropped five times. The contact had not experienced a failure.

I have received multiple letter from Ford indicating the solution for this recall 23s65 is available at dealership. However, every Ford dealership I have reached out to says there are no parts available to fix the recall. My Ford dealership has placed the order on November 2025 but they have no eta when the parts will become available.

Transmission downshift to first gear on the highway.

My 2021 Ford F-150 has been inoperable for over three months due to a safety recall involving the rear axle hub. The dealer and manufacturer have been unable to remedy the recall within a reasonable time due to parts unavailability, and no repair timeline has been provided. I requested a loaner vehicle from the dealer and was told there were six to seven customers ahead of me. The dealer reported to Ford corporate that I declined a loaner vehicle, which is not accurate. No loaner was made available to me, and I was forced to obtain alternate transportation through my employer. The dealer initially required payment to inspect my vehicle for the recall and held the truck for approximately one week before stating the issue was not recall related. When I asked how this determination was made, I was told additional payment was required to disassemble the rear hub for further inspection. After escalating the issue and expressing concern about the handling of the recall diagnosis, the dealership director contacted me and later confirmed that the issue was, in fact, related to the recall. However, I was told it would take a couple of months to repair due to parts backorder. At this point, my vehicle has been unusable for over three months with no repair timeline, no manufacturer provided loaner or rental vehicle, and no resolution. I am continuing to make payments and maintain insurance on a vehicle I cannot safely operate due to an unresolved safety recall. This appears to be an unreasonable delay in remedying a safety defect.

The transmission will downshifting and the transmission starts jerking then the engine starts missing for about 30 seconds to a minute but the Ford dealership said it's not showing any codes so it's not happening now I can't get it fixed they didn't think having a vehicle that starts missing for no reason isn't a problem but the torque converter won't throw codes and it's attached directly to the crankshaft so it's messing with the engine to get it to start missing.

Dealer has now had my car for almost 60 days with no resolution manufacturer recall number23s65 NHTSA recall number23v896 my asset is basically frozen at this point with zero eta and any care from Ford. I am willing to trade it in at this point but can’t even do that.

I have taken my truck to two seperate Ford dealerships. Both acknowledging something strange on the transmission with the hesitations, the jerkiness and the hard shifting that happens. The first replaced the trans fluid and the filter. The second dealer replaced the valve body. During the 5th visit. They had me drive around their foreman to show him the problems. While he did feel the jerkiness and hesitations I feel, he said that its pretty much not bad enough yet and that the dealership would be held responsible for the cost of a new transmission if they replaced it and Ford deemed it not needing to be replaced. Ford corp told me they wouldn't intervene with their attempt to fix it. The Ford dealer sent me home and didn't fix anything the 5th time, even after explaining I felt harsh jerking on the way home to the point it felt like it was kicking me and a bunch of white smoke came out of the tailpipe. I even provided them a video of the white smoke when completely stopped after had been driving for 3 hours. The service on this truck is completely up to date and absolutely no reason at 41k miles I should have all these issue with this transmission. Ford has been resisting to replace this transmission but is willing to sell me a $4k extended warranty. Its getting old. This saga needs to end. Ford needs to just recall these transmissions already. This fight has been ongoing long enough! and Ford corporate wont even help me. During the 3rd and 4th visit they replaced the valve body sent me home and the next day I had to bring it back after coming out of my work and transmission fluid being all over the ground right after they "fixed" it. They didnt give me a tow truck but rather made me drive almost 20 miles to their dealership. They claim the transmission pan warped but they just didnt screw the pan on correctly and ensure the pan seal was in good shape.

Hello, my 2021 Ford f150 with 10 speed automatic transmission is believe 10r80 is the issue. I've experienced some delayed shifting, erratic shifting. Also, some when coming to a stop. I've had the transmission serviced with a fluid drain and new filter. Current mileage approximate 53k. I did research to find the 10 speed. Transmission to having issues with a class action lawsuit.

Daytime running lights quit working. This happens on numerous f150s with reflector headlights. Transmission issues hard shifting and downshifting that could cause wreck due to sudden slowing of vehicle. Known issue with f150 2021-2023.

The contact owns a 2021 Ford F-150. The contact stated that upon taking the vehicle into the dealer for regular service, the contact was informed that the rear axle hub was fractured. No warning lights were illuminated. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA campaign number: 23v896000 (power train); the VIN was included, but the vehicle had not yet been repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 32,000.

The transmission was slipping in 2nd and 10th gear. This was confirmed by the dealer. A full transmission had to be replaced at 66,000 miles. The vehicle had an excellent maintenance record and well kept. Ford did pay half of the cost but I still ended up spending $6k out of pocket and my vehicle was in the shop for 27 days.

The 10r80 transmission is failing. I have safety concerns for myself and others due to loss of acceleration and violent down shifts. The issue has been reproduced by my mechanic shop. The dealership will not help me with the issue. There have been no dash lights until the failure occurred. The only indication was some occasional rough shifting leading up to the incidents.

We have taken our F-150 to the dealership multiple times for a clunking issue under the truck, and have been told that it is related to the recall issued. Although, it has never been repaired. We take it in a couple of weeks ago for the exact same issue that has been going on since October of 2024 and suddenly it is a transmission issue. We are told that they can gladly repair the transmission for $10,000 now that they put us off until the extended warranty expired. I think this is happening a lot, as the exact thing happened to my friend's daughter. Also, it appears upon doing a little research that 2021-2024 F-150s and explorers have this issue frequently well before they reach the 100,000 mile mark. Many times before the buyer has even paid off the loan for said automobiles. This surely poses a safety risk, as well because you never know when the vehicle is going to fail. Also, my husband took his truck in telling them that it wouldn't go into gear and the shifter had a problem in February of 2024, it took the truck's shifter literally breaking off in the driveway (thank goodness) and being towed in to the dealership before it was repaired.

When making right turn to get on highway accelerate pedal pressed vehicle wont take of after releasing pedal and pressing again few times thn it takes off. Its been twice already I was gonna get rear ended.

My truck has had both rear axle bolts broken since October of 2025. This is part of the recall 23s65/23v896 for the max tow axles. My dealer ordered parts in October, yet they're still supposidly on national backorder from Ford. New vehicles are coming off the assembly line with these axles every day, and I can find several oem parts websites online selling the fixed axles, yet Ford continues to tell me that I need to wait longer. This is a safety issue since both of my rear axle bolts are broken, so if the axle were to slip out of the splines I could lose all power.

Pulling onto [xxx] , with cars coming at me at 55 mph or more, the transmission slammed into gear and caused it to stall. Dealership diagnosed cdf failure and recommended replacement of the transmission. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Ford has released multiple tsbs related to a known design flaw with their 10r80 transmission that causes the transmission to experience hard shifts while moving and often occurs in traffic. The hard shifts can cause the vehicle to stall which creates a very unsafe situation, especially on highways and interstates. The transmission defect has been redesigned in newer vehicles, however, there are thousands if not hundred of thousands of these vehicles on roadways that can break down suddenly causing a major accident. The Ford owners forums have been riddle with concerns about this issue related to the cdf drum in the 10r80 transmission.

4 months after taking vehicle in for recall fixes, both recalls on vehicle have not been remediated due to parts not being available. No eta on availability and get a run around when asking for more info. Hub shaft recall stats that driving the vehicle with a broken hub bolt will wear shafts but no loaner was given so I have no choice but to drive vehicle with a broken bolt. Ford customer service told me its ok to drive the vehicle but never stated if they are replacing the entire rear end or just the parts listed on the recall. . What is dirving the vehicle ruins the splines on the shafts. Are they going to replace those as well?.

We own a 2021 Ford F-150, that is down since the first of September, 2025, due to recall 23s65. We've been in weekly contact with our local dealer since then. They are doing everything possible to get the parts in to repair our truck, but parts are and have been on backorder, with no eta from Ford. We have also been in contact with Ford customer service in dearborn and had an open case with them. They have closed our case because they can't help and told us the local dealer is responsible, then they moved us to recall department now and no longer respond. We feel 4 months is a ridiculous amount of time on Ford's part for these parts to be on and still on backorder. We have no option for help and wondering if you could. It's has been an extremely difficult situation for us to be without our truck for this extended amount of time.

The transmission shifts hard from 1st to 3rd during the first few minutes of operations. When I make the turn out of my resident each morning, it nearly fishtails due to the fat that the transmission stays in 1st gear until around 2500-3000 rpms, then shifts violently to 3rd gear. The tires actually spin. After a few stop and goes, and the transmission has cycled through the gears several times, it shifts normally. I have taken it to the Ford dealer in royal palm beach, FL. They said that there were no recalls, despite there being several complaints from other truck owners about the same issue. Ford knows that the 10 speed transmission in the f150 has shifting issues.

Fords 10r80 transmission is a known failure point. Why are they not recalling it?????? I bought my vehicle used from a Ford dealership with 36k miles. Quickly realized it was a lemon but nothing I could do. The biggest issue is the transmission. The transmission does not shift properly, it slips, it has major clunking and hard downshifts sometimes pushing through brake pressure, etc. I fought with two separate dealerships to take a look and after months of them trying to convince me it was fine, they tore it apart and it was damaged. Now the "rebuilt" trans is doing the same thing even leaving me in limp mode just now until I turned the vehicle off and back on. You guys need to do something about this please. Ford is not doing anything and its hurting consumers and going to cause an accident if it hasn't already.

My 2021 Ford F-150 5. 0l v8 with the 10-speed automatic transmission has ongoing and severe transmission issues that create a dangerous safety hazard. The vehicle intermittently loses power and feels like it slips completely out of gear while driving, including at highway speeds. This sudden loss of acceleration is unsafe and could easily lead to an accident. The most severe issues occur between 2nd and 4th gear. The truck slams in and out of gear, hesitates, and lurches violently. Shifting often feels like the transmission is “hunting” for the right gear, and hesitation occurs throughout other gear ranges as well. At times, it feels like a new driver learning to operate a manual transmission—jerky, unpredictable, and unsafe. This is not an isolated problem. After researching on multiple owner forums, I found many other 2021 F-150 owners reporting the exact same issues: slipping out of gear, hard shifts between 2nd–4th, hesitation, loss of power, and violent shifting. These widespread complaints strongly suggest a defect in the design or function of this 10-speed transmission. This is not just a drivability issue—it is a critical safety concern. I have lost power while merging and while traveling at highway speeds, leaving me unable to accelerate when needed. In city driving, the hesitation and gear slamming create dangerous situations when crossing intersections or pulling into traffic. Given the number of owners reporting similar problems, I believe this is a systemic defect that requires immediate investigation and action. Ford needs to address this transmission failure before it leads to crashes, injuries, or fatalities.
