general problems of the 2021 Ford F-150 - part 1

I’ve had the transmission replaced along with the torque converter when both failed less than a year ago. The transmission and the torque converter are now doing the same thing it was doing prior to the replacement. The transmission slips in 4th, 7th and 8th gears. The torque converter whines loudly. Ford will not fix the issues with these transmissions without a hefty out of pocket fee. It’s become very well known that all of these 10r80 engines/transmissions are a major problem that Ford is not remedying. If this transmission gives out when I’m on the interstate it’s going to cause a major wreck. I live in the mountains, so a bad transmission can quickly turn into a deadly accident. These transmissions need a permanent fix, not for us owners to continue paying thousands of dollars for replacements or rebuilds. This is Fords problem.

Giving an error of reverse assist and not available when starting truck and when placing truck in reverse. Have look up to seen if included in the recall that was issued 6 days ago. Have called dealership to confirm that not part of recall. The message just showed up last night. This truck should be included in the recall.

My truck has harsh shifting when I accelerate and when I slow down. It skips out of gear into neutral and then goes back into gear. I believe the problem is that my system isn’t communicating with the transmission correctly. There weren’t any warning messages before or after this problem started. I did some research, and my model and year of my truck do have a problem like this no dealership or service center has not inspected this problem.

The contact owns a 2021 Ford F-150. The contact received notification of NHTSA campaign number: 23v896000 (power train). The vehicle was taken to the dealer, where it was diagnosed and determined that the passenger’s side rear axle shaft assembly had failed and needed to be replaced. The vehicle was not repaired. The dealer informed the contact that parts were not yet available. The manufacturer was made aware of the issue. The failure mileage was unavailable.

-the hub bolt in the rear axle broke. Truck had to be towed to dealership. Problem was confirmed by dealership. There was no warning lamp and only found out due to flat tire. -in 12/2022, power train failure left vehicle "dead" in the middle of the highway with family of four stranded 400 miles away from home.

The vehicle is experiencing a chronic, documented loss of engine coolant with no external leaks identified, accompanied by a persistent odor of burning coolant. Despite nine months of notification and two separate Ford authorized dealerships attempting repairs, the defect remains unresolved. To date, dealerships have performed only 'surface-level' pressure and dye tests. They have refused to perform thorough diagnostics despite the clear evidence of consumption. This creates a severe safety hazard: coolant loss on this engine platform is a known precursor to sudden engine stall and potential engine fire. By failing to identify the internal leak path, Ford is requiring me to operate a vehicle with an unpredictable mechanical deficit. The absence of a warning lamp (cel) does not mitigate the risk; it confirms a mechanical failure that the current onboard diagnostics are failing to capture before a catastrophic event occurs.

The contact owns a 2021 Ford F-150. The contact stated that while stopped, the vehicle hesitated and shuddered while depressing the accelerator pedal. There was no warning light illuminated. The vehicle stopped in the middle of the road and failed to move even while in neutral(n). Due to the failure, the vehicle was towed to the dealer, where it was diagnosed with a defective fuel pump. The contact was informed that the VIN was included in NHTSA campaign number: 25v455000 (fuel system, gasoline); however, the parts for the recall repair were not yet available. The contact was provided with an estimate for the repair, which the contact approved. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

I put the truck into reverse and tried to back out of my driveway. The truck didn't move for several seconds, then started to move. I brakes, shifted into drive and the truck continued to move backwards. I applied the brakes and the transmission seemed to spin before it moved forward. I drove down the street to the corner. I applied the brakes and the was a shudder and bang as the transmission downshifted from 4th to 3rd. This occurs intermittently over the last 3 months. When I searched online, I learned that these symptoms are consistent with those described in Ford TSB 23-2350. I had an independent mechanic confirm the problem and he noted the fluid was dark. Whrn I spoke to the dealership, they tried to explain the issue was due to the transmission being cold. I'm the original owner of the truck.

10 speed transmission is not working 1 still gear hyper extends dont wanna shift 2 gear bangs 3 rundown rough then sometimes dowshifts back to 2 nd gear the transmission dosent wanna get hot to normal level.

The transmission shifts hard when downshifting from 10th gear on the highway. There is a loud audible clunk that you can also physically feel. Also when shifting around 3rd gear during city driving there is the same problem. Both of these could lead to loss of traction/vehicle control.

There is a hard jerk that happens when moving from a dead stop and then it will shift into gear. Its been reproduced by a maintenance shop. They stated it was the transmission. It has not been inspected by a manufacturer. There was no warning lamps which causes a high risk of safety, including a possibility of accident while on the road.

When the truck is put into reverse especially when cold the transmission does not initially go into gear. When it finally does the vehicle lurches rearward violently and I have to slam on the brakes to not hit anything. The transmission was just "bench" rebuilt under the Ford powertrain warranty supposedly with a cdf drum and valve body replacement along with software updates including adaptive reset and relearn with the appropriate drive cycles however the vehicle still exhibits this condition. I called Ford customer service and filed a complaint with them last month. They told me to bring to another dealer which the vehicle is currently at and has been for a month. They claim that it is normal for this transmission and refuse to fix it. I have video evidence of the truck being put into reverse and the rpm rising before it slams into reverse. I also demonstrated first thing one morning to a technician after a cold soak overnight and he agreed that the vehicle has a delayed engagement in reverse and when it did finally engage it did so violently. The dealer told me to record it and that would be the best evidence and I did along with presenting it to them. After this they changed their mind and said actually a technician has to witness which I also did. Again they said this wasn't good enough. A field engineer supposedly looked at the vehicle and they wont tell me what he said. Very odd. I feel like im getting the run around and have an unsafe vehicle that Ford refuses and it trying to worm their way out of safetly fixing! in the description below is when the truck can be seen in the video recreating the problem however it has done this countless times.

My truck started to over heat due to lost of radiator fluid. The cause was the transmission coolant line chafing against front drive shaft.

2021 Ford f150 powerboost hybrid. There is a lot of internet chatter and forum chatter about known issues with the following, and it recently almost led to a major and likely serious injury accident. Specific parameters: low speed (~5 mph) slow roll under internal combustion power, not battery in 2nd gear only when gas pedal is pressed vehicle does nothing. Does not respond. Two choices are to hammer the gas, or hit the breaks. Does two things, slams forward eventually after 3-4 second delay if gas pedal depressed or shifts down or into electric mode (internal combustion off) and then will once again go from first to third in normal acceleration progression and pace they must have an issue with the standard 1-3 skip programming with ice power and 2nd gear being a hang-up I almost got t boned by a semi truck due to this with family in car. This could have been deadly. It happens as an annoyance at least once per day but this one was scary. Online, and based on what I can find - Ford is aware of this issue as they have the 1-3-5 programming in the transmission but when it finds itself (due to real world driving conditions) in 2nd gear under internal combustion, it does not know what to do. I brought it to Ford last year in anchorage and they are attempting to blame it on normal hybrid system operation. That is not the case. It would be something that could be duplicated but with effort. A basic, simple test drive is not going to find this. They are aware of this being an issue. If you have any situation where you are rolling through, merging into traffic, or other scenario where you end up in 2 under ice you are in trouble. Dangerous, scary, and totally a manufacturer issue that is known and needs to be taken very seriously.

Loss of power pulling onto a major highway -- luckily I was able to pull off onto a side street but had I not I could have been rear ended. Vehicle has been at athens Ford since January 15th -- Ford states on their recall notification that parts are readily available -- they are not. I have been waiting for 2 months to get my vehicle back and have no resolution in sight. Dealer states they have no eta on parts availability; Ford customer service also does not have an update.

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.

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.
