2021 Ford Expedition Powertrain & Transmission Problems

Transmission harsh shifting. Common problem with ford on the 10r80. Was told from ford need new transmission

The 10r80 transmission went out in it after 80k miles. It would get "stuck" in gears and not want to shift. The lack of shifting would cause the vehicle to stall while driving. Ford was able to reproduce the issue and the transmission is getting replaced by Ford through our extended warranty company. There was a clunking noise when driving prior to the transmission having shifting issues. No, there were not any warning lights when this was happening.

The 10r80 transmission of this vehicle failed resulting in erratic shifting, slowing and stopping of the vehicle in traffic, having to pull over in the middle of traffic. Rapid acceleration and deceleration resulting in jolting the people in the vehicle and abrupt speed changes. This has been confirmed by a private mechanic and a rebuilt transmission purchased from local Ford dealership. The broken transmission will be returned to Ford as the core is required to be returned for deposit refund. There were no warning lights or indications of failure other than shifting issues.

The cdf drum in the 10R80 transmission in 2021 Ford Expedition has failed causing inability to accelerate or decrease speech reliably. For safety during interstate driving, there is a indisputable need for quick and reliable increases and decreases in speed. Being able to clear an intersection quickly is important not only for the driver's safety but the safety of others in an intersection. Dealership has confirmed the problem. Ford released a TSB that has been around since 2023 regarding how this part fails and needs to be repaired. There were no warning lights or messages about the problem. The vehicle was purchased used at only 60,000 miles and dealership made no indication that transmissions had been an issue and could be a safety issue going forward.

Most mornings when I shift the vehicle from Park to Drive the transmission slams into gear and it feels like the vehicle just hit a wall. Also when shifting from 4th through 8th gear the transmission shudders through the shift sequence and sometimes it completely cuts out, total loss of power and have to coast to a stop on the side of the highway. This happens all the time.

Faulty CDF Clutch Drum. The vehicle failed to shift properly while driving in mountains which could have lead to a runaway. Problem has been identified by my dealer and is a known issue with 2017-2023 Ford Expedtions. Vehicle inspected my FoMoCo mechanic and found issue with drum. No warnings or prompts before issue occurred.

During highway operation, vehicle transmission makes very loud and angry sound and then loses ability to move , almost caused us to get hit at an intersection. Vehicle often jumps violently when shifting to reverse, and often loses propulsion when going uphill and shifting. No issues have been identified by mechanics but I have found several forums on line with drivers reporting similar occurrences. This is very dangerous and if not addressed will result in loss of life. We purchased this vehicle certified by the dealer with 92000 miles on it and it began doing this less than a week after purchase. We took it in for recall work and reported it and they said nothing was wrong with it. Manufacturer failure to rectify this very common problem is going to cause may citizens to be injured or killed.

Have had jerky shifts and hard down shifts while driving 2021 Ford Expedition. Told dealership and was told it was normal. Then went in for oil change told the dealership about lose of power while shifting and hard shifts they advised to have transmission fluid changed. Not even 3 weeks later while pulling out onto a busy road my vehicles engine revved very high but the transmission never engaged past 2nd gear. I was almost hit by a car coming at me on the 2 lane road. After letting off the gas and then reapplying gas the transmission engaged. I drove to the dealership. Today they informed me that the transmission has multiple failures at the shift point between 1-2 and 7-8 along with hard down shifts between 4 and 3 gears. Was informed that the transmission would need to be replaced. I never got any error or warning codes that anything was wrong. I told the dealership that I felt unsafe driving the vehicle due to the transmission. The first instance happened less than a month ago. My vehicle is at the shop now waiting to have a replacement at my expense when Ford knew what the transmission is like.

While attempting to pass a slower moving vehicle and changing from the right lane to left, I attempted to accelerate past the vehicle when the check manual light appeared on the vehicle display dashboard and I lost all power. I had no acceleration and no power from the gas pedal, after gliding past the slower vehicle and completely taking my foot off the gas pedal, the truck reset itself and power came back to the vehicle and was able to accelerate again, as if nothing happened.

The contact owns a 2021 Ford Expedition. The contact stated that while driving at 45 MPH, the engine overheated. The message “Drive Mode Inoperable” was displayed. The contact pulled over for 20 minutes, and the vehicle was restarted. The vehicle was towed to the local dealer, who confirmed that parts were on back order for NHTSA Campaign Number: 22V346000 (Engine). The vehicle was diagnosed, and it was determined that the failure was due to the transmission. The vehicle was not repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 99,130.

Nn 9/15/2025 While the car was running but parked, we began to smell burnt plastic/electrical. Upon trying to shut off the vehicle several service lamps came on advising to go immediately to a service center and that there was a powertrain issue. Vehicle would also not shut off. Upon arrival at dealership they diagnosed that the battery box had corroded and would need replaced under the 1time battery Junction box replacement campaign (22N19). Upon repair they discovered that the wiring harness was badly melted and would need replace part [XXX] . The problem lies here. This part is backordered with no date for availability. Ford refuses to acknowledge this as a problem, and will not help with rental or loaner assistance, as that repair shouldn't take more then a few hours to complete.

Automobile falls out of gear randomly losing all forward power to move the car. While pulling out into traffic, this causes the car to not gain speed with traffic endangering those in the car. Dealer currently has the car and has quoted to replace the Transmission with a rebuilt unit. No warning lights in the car to tell us anything was wrong. Based on research, I believe Ford knows this transmission is faulty, and will not recall due to cost. Issue has scared my wife and family on multiple occasions before finally getting a scheduled check on the car.

10R80 transmission jerky shifting and failing to engage correctly leading to loss of power and unsafe driving/ jerky acceleration.

While towing a rented trailer from Tractor Supply, the trailer detached because it was not properly secured by store staff. The trailer struck the rear bumper of my 2021 Ford Expedition, causing visible body damage and raising concerns about hidden damage to the drivetrain and transmission due to the sudden force of the impact. After the incident, the vehicle was taken to a Ford dealership for inspection. Documentation exists showing that additional drivetrain and transmission evaluation is needed to determine the full extent of damage. The rear-view camera is also under active NHTSA recall (25V048), and its poor image quality complicates safe reversing after the incident. The safety risk is significant: the trailer detachment created a roadway hazard and impact, while the rear camera defect reduces visibility and increases crash risk when backing. The vehicle has been inspected by a Ford dealership and is being reviewed under an insurance claim with Tractor Supply’s insurer. Full documentation of the service visit and inspection is available upon request.

I originally leased and have since purchased this vehicle. Since owning the vehicle, it sometimes has a harsh shift between gears. It is so harsh that I have mentioned it to at least two different Ford dealerships during the transmission warranry period. No remedy was provided at the time. The car has continued to have shifting issues and now the car will pop out of gear while driving, which is a major safety issue. We informed a Ford dealership about this experience and they are now telling us we need a new transmission as they found metal in the transmission fluid. The transmission warranty just expired and there is a NHTSA bulletin about this very issue and there is an open recall on the power module for this car.

Transmission has completely failed at 68,000 miles and 4 years old. Ford is willing to cover cost of the tramission with a “partial good faith” agreement but the dealership who provides the service is charging $5,656 to put in new transmission. This is a widely known transmission problem with safety issues with multiple service bulletins. They are passing the issue onto the consumer instead of recalling. Shameful.

Transmission Failure Rough or jerky shifting: This occurs when accelerating or decelerating, and even when shifting between gears. Delayed gear engagement: Shifting from park to drive or reverse can be slow, or the vehicle may lunge into gear. Transmission slipping: The transmission slips between gears, causing a loss of power or acceleration. It can also cause a violent grinding/shaking between shifting gearshifts resulting in loss of acceleration.

The transmission shifts gears irregularly and has loss complete power when going up hill. This is a known issue with the 10 speed transmission but Ford has not corrected the issue that is impacting thousand of vehicles. This issue with the shifting happens everyday that I drive it.

May 17th was trying to get over one lane on service road, gave car gas and it acted like it fail out of gear, let off gas and then it was fine. Did the something again about 4 hours later. Car only has 94,000 miles on it and dealership is saying that it needs a new transmission. I have never hauled anything with this car, only driving on the highway. I did take my Ford in at 57,000 because it was rough sounding when it would change gears. They said they couldn't find anything wrong. Now we need a new transmission and it is out of warranty of course. I just don't see how this transmission could not last longer then 94,000 miles. The note on the car still has a few years left on it. There are not active recall per Ford Relationship Center. I also have a claim with them as well. They told me to made a claim there as well.

Wiring has soy based bioplastic insulation which apparently attract rodent damage. This damaged battery, caused spark plug to be damaged and need to be replaced. It has also caused voltage and computer performance problems affecting engine idling and shifting. Issues were extremely unpredictable and hard to diagnose leading to 5 visits to the shop and many failed attempts to repair.
