general problems of the 2021 Ford F-250

Transmission has shifting issues. Sometimes is don't down shift below 4th gear and when in an intersection truck barley moves then it shifts hard and can move . It also is constantly shifting between gears. It will shift form 10th to 5yh while driving.

The vehicle experienced a sudden loss of motive power and became inoperable due to failure of the high-pressure fuel system. This VIN is subject to an active safety recall (NHTSA 24v957 / Ford 24s78) addressing high-pressure fuel pump failure that can result in loss of motive power while driving. Prior to failure, the vehicle exhibited reduced engine performance and drivability issues consistent with fuel system malfunction. No water-in-fuel warning or alert was displayed prior to the failure. The vehicle was inspected by an authorized Ford dealership. Ford and the dealership asserted “fuel contamination” as the cause and refused to repair the vehicle under the recall or warranty unless the customer paid for diagnostic teardown. The recall repair was not performed. The vehicle remains unrepaired and was removed from the dealership. The loss of motive power created a safety risk to the occupants and other motorists. We are concerned that a recalled safety defect affecting the fuel system is not being remedied and is being mischaracterized to avoid recall repair.

The contact owns a 2021 Ford F-250. The contact stated while driving approximately 5 mph, there was an abnormal popping sound coming from under the floorboards. The contact was towing a 16-foot dump trailer with an approximate load of 16,000 lbs. During the failure. The contact stated no warning light was illuminated. The contact stated that the vehicle lost motive power. The contact stopped the vehicle and inspected the rear of the vehicle and became aware that the rear of the drive shaft was hanging down and touching the road surface. The contact had the vehicle towed to a dealer who diagnosed that the rear axle housing had failed, causing the driveshaft to shear off. The vehicle was not repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA hotline for assistance. The contact researched online and related the failure to NHTSA campaign number: 21v536000 (power train); however, the VIN nor the model vehicle was included. The failure mileage was approximately 52,000.

10 speed transmission causing unsafe operation. Stalling , stopping decelerated shifting. . Replace with a new transmission by Ford and nown14k miles in its doing the same thing. Someone will wreck because of this and it won't be good!.

My 2021 Ford F-250 equipped with the 10r140 10-speed transmission suffered a sudden internal failure around ~100,000 miles. The failure symptoms and internal damage match the defect Ford acknowledged in safety recall 22v-256, which applies to the 2020 F-250/f-350 trucks using the same 10r140 transmission. Despite identical symptoms and the same transmission design, my VIN [xxx] ) was excluded from the recall. Nhtsa’s VIN decoder also returned an “ambiguous model year” notice, suggesting this vehicle may have been built during the transition period where Ford continued using the same defective 10r140 components. Symptoms experienced prior to failure included harsh shifting, delayed engagement, gear slipping, and eventual loss of drive. A transmission shop stated they “won’t touch these transmissions” due to known issues. The failure created a serious safety risk due to sudden loss of power while driving. This appears to be a recall scope error. Early 2021 units like mine are experiencing the same 10r140 internal failures as the recalled 2020 population. I request NHTSA investigate whether Ford under-reported the affected VIN range and whether the recall should be expanded to include early-2021 F-250 trucks. 10r140 transmission failure on a 2021 Ford F-250. Identical to the failure described in 2020 recall 22v-256. Early 2021 VIN, suspected recall scope error. Approximately sometime in January 2025 not exact date. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Bad transmission at only 75,000 miles.

December 24, 2024, traveling in a line of vehicles on a two lane road, the vehicles ahead of me slowed to almost a complete stop. I braked and slowed along with the traffic to a near stop. As the traffic began moving again, I released my brake and pressed the accelerator pedal. The engine rpm's raised but the the vehicle did not move. It felt as if the transmission was in neutral. After releasing the accelerator and pressing it a second time, the engine revved again and then the transmission made a loud bang engaging the transmission and lurched the truck forward. I released the accelerator and braked to avoid striking the vehicle ahead of me. I pressed the accelerator again only to have the same scenario happen again. Fortunately, each time the truck did this, I did not strike the vehicle ahead of me. This is the not the first incident of this occurring with this vehicle. The truck then drove normally and did not experience this again on this trip. This had occurred previously a several months before with the same issue. I am unable to duplicate the issue and am unsure what causes the truck to do this. It appears that the transmission is unable to determine what gear it needs to be in and therefore acts as if it is in neutral when this occurs.

This vehicle is subject to two open safety recalls for which no repair remedy is currently available from the manufacturer: 1. Recall 24v957 (24s78) Dec 20, 2024 involves the high-pressure fuel pump and powertrain control system. The recall states the fuel pump may fail and cause extended cranking/no start or loss of motive power while driving. Loss of motive power while in traffic or while towing increases the risk of a crash. The manufacturer has stated that parts and/or software are not available to repair this defect. The vehicle is regularly used for towing a recreational trailer, which increases the safety risk if loss of power occurs during operation, especially at highway speeds or while merging. 2. Recall 25v686 (25sa8) oct 10, 2025 involves the 360-degree/rear-view camera system. The recall states that the rear camera image may become dark in certain reversing situations when front and side cameras are exposed to significantly more light than the rear camera. Reduced visibility while reversing increases crash risk, particularly when maneuvering a large pickup truck. The manufacturer has acknowledged both recalls but has not provided a repair remedy within a reasonable timeframe. The powertrain-related recall has remained unresolved for an extended period. The vehicle has not been repaired because the manufacturer states parts/software are unavailable. At this time, the defect conditions have not resulted in a confirmed failure event, but the vehicle continues to be operated with open safety recalls that cannot be remedied. The safety risk remains present due to lack of available repair. Due to the prolonged unavailability of a repair remedy for a recall involving potential loss of motive power, I am unable to safely use the vehicle for its intended purpose of towing, as doing so would increase the risk of a crash if the defect occurs.

This car has had a recall for almost year. I’m am terrified to drive my truck especially with my kids in it. Sometimes if I press the gas trying to cross traffic, it takes a while to go. Also sometimes it won’t crank up and start. It takes awhile few tried. My back up camera doesn’t work the way it should.

The contact owns a 2021 Ford F-250. The contact stated that while at a stop and attempting to accelerate, the rpm's rapidly increased, but the vehicle failed to respond as intended and experienced a loss of motive power. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA hotline for assistance. The failure mileage was 70,000.

Transmission would not engage the next gear , while proceeding through a large traffic intersection. Very scary.

The transmission suffers erratic shifting normally between 3rd to 5th, and 9th to 10th gears where it feels as if the transmission goes into neutral when upshifting or downshifting between these gears. But, one issue occurred which has concerned me. After stopping at an intersection, when it was safe to proceed, I moved my foot from the brake to the gas pedal to proceed. The engine revved to higher rpm's, but the truck did not move as if it was in neutral instead of gear. As I looked down at the tachometer, the truck suddenly locked into gear causing the tires to chirp and the truck then lunged forward through the intersection. This was a t intersection where you have to turn right or left. This incident was so harsh and unexpected, it threw me back into my seat. I was able to maintain control and make my turn to the left without going off the end of the road. This incident has not happened again, but the erratic shifting continues.

My truck currently has 92,305 miles and are all highway miles. This truck is not used for towing outside of the weight rating. The issue is that there was a vibration when I reached speeds of 65mph and higher. The dealer states that the rear end has excessive back lash, excessive wear in the ring and pinion gears and metal shavings in the rear differential fluid. Ford's rear differential service recommendation is 100,000 miles which I have not reached. I'm now required to pay over $3200 in repairs for the carrier bearings, hub bearings, pinion bearings, seals and rings plus the transmission fluid. Based on my driving habits, I do not think this issue is something that I caused, I believe it to be a Ford issue which they deny. I have read many blogs online where other owners have this same issue and someone needs to look into it further.

Known mechanical design issue with the 10r140 transmission cdf drum where a bushing moves blocking / partially blocking fluid transfer ports. This causes transmission fluid overheating, clutch slippage, hard shifting, etc. This mechanical design issue poses a danger to the driver, passengers and other surrounding vehicles when this potential failure occurs.

Vehicle surging accelerator acts like lake of air theb shoots off.

I bought this truck used with 20k miles on it, after only two days of driving it. I was in the credit union parking lot, started it up, foot on the brake, put the truck in drive and it leaped forward. I had to jump harder on the break to stop the motion. I almost hit the truck crossing in front of me. If he was heading the other direction and closer to me, I would have easily hit him. This morning 28 oct 2022, I stopped at the gas station and filled up and the same thing happened when leaving the station, but no one else was around.

Transmission hard shifting from 1-3 and hard shifting down from 10-8.

Dear staff; I purchased my 2021 Ford F-250 new July 25th, 2021. I noticed my undercarriage was covered in great portions of rust. The front driveshaft to the outer ends and the rear housing, including the rear driveshaft u-joint has a significant amount of rust. What’s surprising is I have only 5400 miles and the truck appears to look 20 years old. I have a neighbor who is a gm of another competitor dealership. He crawled under the truck and said this is a safety issue which needs to be addressed. Two Ford dealership service managers informed over the phone this is a common issue and not to be concerned. I have owned eight Ford pickups throughout my life and never had this deep concern. Knowing this rust has perforated the tie rods, I don’t feel safe driving this $60,000 vehicle. My only recourse since Ford won’t honor its warranty is for me to trade it in on a GMC. I have been loyal to Ford for 36 years to finally get shrugged off.

The forward heat shield/sound insulator became dislodged from the retainers and dropped onto the forward driveshaft. This damaged the driveshaft. This incident could have resulted in the driveshaft fracturing and may have resulted in an accident. This condition is documented in NHTSA campaign number 22v-087 and Ford recall 22s09. Per the Ford dealer who repaired the truck and per an employee of Ford motor company, the two wheel drive Ford super duty trucks have not been included in the recall. These places thousands of vehicle owners at risk of an accident related to this condition.

The 10-speed automatic transmission shifts hard and randomly. Leaving a stop sign, at any rate of speed, causes slippage in the shifting. Sometimes it'll shift too slowly, resulting in a jerky motion of the vehicle. Sometimes when on the highway, usually traveling at 68mph (cruise control), the vehicle will randomly jump gears when it's not necessary. Recently while getting up to speed we heard a large grinding noise shifting into 4th gear. The vehicle, otherwise, runs great. The transmission leaves alot to be desired and I do not have any confidence in the shifting. It's comparable to a teenager just learning how to drive a stick shift. If I wanted that, I would have one. My transmission fluid is where it should be and the vehicle has less than 8,000 miles on it.

The contact owns a 2021 Ford F-250. The contact stated that upon starting the vehicle, the transmission was slipping. The contact wait for a while before the vehicle responded as needed. There were no warning lights illuminated. The vehicle was taken to a local dealer, but the vehicle was not diagnosed or repaired. The vehicle was taken to three other local dealers: desoto Ford (3039 se hwy 70, arcadia, FL 34266); mcdonald Ford (6790 midland rd. , freeland, mi 48623); and richardson Ford (3781 s huron rd. , standish, mi 48658), and was made aware of TSB: ssm 51420; and that the vehicle was working as designed. The contact was informed that engine oil was moving into the torque converter and needed to warm up for proper operation. The mechanic informed the contact to let the vehicle run for a while before shifting into gear. The manufacturer was contacted and referred the contact to the NHTSA hotline to report the failure. The failure mileage was approximately 2,000.
