NHTSA Complaint #11540648 — 2021 FORD EXPEDITION

After owning the car a year and about 15,000 miles I started having transmission rough shifting and lurching motions when shifting - violent lurching. I took it in to the dealership and they reset the adaptive learning component for the transmission. Nothing changed. Brought it in again and drove with technician and was able to reproduce issue. They replaced the transmission and the problems continued and actually increased with losing all acceleration on the freeway (floppy pedal) and then completely losing 10th gear when trying to pass another car. Luckily I was able to pull over and I did not cause an accident. It also threw a code/warning light at that time. I took it back to the dealership. They assessed and reset adaptive driving module. It then lost accelleration and wouldn't engage 10th and started smoking. Took it back to dealership and they claimed all that was due to over full transmission fluid. Original problems of rough shifting, lurching, clunking still existed. I filed a report with Ford and got a case number with the concern department. This resulted in the rear end of the car being replaced??? Car still has transmission issues, with all the above mentioned issues, and now delayed acceleration in the lower gears. Enough is enough fighting about fixing it for a year, it has been in for repairs 7 times, and over 49 days of rental cars . The vehicle does not cause warning lights at any point with the rough shifting, lurching, or lack of acceleration. All have been experienced at various times by the dealership. No solution to date.
