2021 Ford Expedition

The 10R80 transmission, even after rebuilt by the dealership continues to shift in unexpected ways (hard shifts, not picking the right gear, hesitation under acceleration). It doesn't happen all the time, and isn't reproduceable at will. When the problem occurs, it is very noticeable. The vehicle will hesitate and not accelerate when pushing on the gas pedal, and then all of a sudden jump forward unexpectedly. The dealership has examined it after the transmission was rebuilt, and states that it is operating normally, but we were unable to duplicate the problem at that time. The next day, it happened again while driving on the highway when merging into traffic. Pressed on the gas pedal, but the car did not accelerate as expected (long hesitation), and then the transmission decided to change gears, and experienced hard shifts to the point the whole car jerks abruptly (this was NOT because of extreme pressing of the gas pedal). Just normal pressure on the gas pedal, and it will randomly decide how it will shift.

The contact owns a 2021 Ford Expedition. The contact stated while driving 80 MPH, the vehicle began to shake forcefully. The contact stated that the check engine warning light was illuminated before the vehicle stalled. The contact was able to park on the side of the roadway, restart the vehicle, and continued driving. The contact took the vehicle to the local dealer who was unable to duplicate the failure. The contact continued to experience the failure within 24 hours. The contact took the vehicle back to the local dealer, where it was diagnosed with needing the fuel injectors to be replaced. The vehicle was repaired but experienced the failure a third time. The contact stated the catalytic converter, and the transmission warning lights were illuminated. The contact took the vehicle a third time to the local dealer, diagnosed, and it was determined that the catalytic converter and the transmission needed to be replaced. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was unknown.

10-Speed transmission frequently shifts hard, and sometimes misses a shift entirely resulting in no power for a few seconds while the transmission tries to "find" the right gear. This has occurred in busy intersections which obviously presents a major safety risk. Awkward shifting started about 2 months ago, complete loss of power has occurred 3 times in that time period. Vehicle is currently sitting in a Ford dealership service department awaiting diagnoses and repair since 5/29/23.

The contact owns a 2021 Ford Expedition. The contact stated while driving 25 MPH, the vehicle lost motive power with a messaging to restart the vehicle being displayed. The contact restarted the vehicle and the vehicle started operating normally. The vehicle was taken to the dealer and the dealer stated that no failure was found. On another occasion, the contact contacted the dealer and the dealer stated that the failure was a known issue however, there was no recall for the failure. The manufacturer was contacted, and the manufacturer stated that the vehicle needed to be diagnosed. The contact was referred to the NHTSA Hotline to file a complaint. The failure mileage was 4,000.

Daily the automatic transmission will erratically and forcefully downshift at highway speed. When changing Driving Modes the transmission display on the dash has numbers disappear and the transmission downshifts with great force which has lead to injuries. After sitting for more than a few hours the transmission will not go into reverse at first but will then violently shift into reverse after several minutes. These issues began not long after we purchased this vehicle new. The service manager at the dealership the vehicle was purchased from when I told him about these problems told me that I don’t understand how a 10 speed transmission works. Sometimes the driver’s seatbelt will not buckle.

I purchased this 2021 Ford Expedition brand new from Ford of Kirkland in WA and discover there's a hard shift or pause when downshifting especially on an uphill. Often time it made a loud metal snapping sound from under the hood when that happened. I was driving on the freeway one afternoon the vehicle jolted and paused and doesn't engage for about 2-3 seconds causing the vehicle behind me to honk. It finally re-engaged after making the loud metal snapping sound. This vehicle had been in service 3 times for the same complaints but still not fixed and discovered that other people with the same Ford vehicle had the same complaints as me

We just purchased this vehicle and started to notice a hard down shift when slowing down from 6th gear. I drove it Saturday January 21st and when I shifted the vehicle into reverse to back into a parking space it threw the transmission into a fault and had no reverse. Still drove forward. Took the vehicle in for service on 1/25/23. They ordered parts to fix the harsh shift. No comment on the reverse issue. Picked up vehicle evening of 1/25/23. Drove from dealership to gas station close to home, about 15 miles. Shut vehicle off to fuel. When I restarted the vehicle it kept pushing forward against trans pawl and then rolling back repeatedly. After it did this 10 times or so I put the vehicle in Nuetral and it proceeded to drive forward for 20-30 feet uphill. After 20-30 feet of driving forward the wrench light turned on and the vehicle stopped driving forward and rolled backwards down the hill as it should have. After this the vehicle had forward gears but no reverse gears. Wrench light and CEL light both illuminated when driving home from gas station. Will have dealership tow back 1/26/23 due to safety issue of vehicle driving forward while not in gear.

Front differential failed. I was driving to the mountains and when I reached snow level it was about 38 degrees F and I slowed to less than 20 mph and switched to 4A. Within a few moments I heard and felt a grinding sound from the front. I have used 4WD several times over the year or so I've had the vehicle and have never heard this noise before. I thought it was the hubs not engaging completely and so I switched it back to 2wd and while the noise was less it continued. I switched back to 4wd and I confirmed that 4wd was working but the noise persisted. I bought this vehicle specfically for its 4wd and my family's life depends on it working when we are up in the Sierras where it snows 2-3 inches per hour. When we returned I immediately took the vehicle to the dealer who informed me that it was the front differential that failed and parts are on back order. I am still waiting two weeks later. They said this is not common but why are parts on back order if it is not so common?
