Automatic Transmission problems of the 2020 Ford Expedition

See attached document for complaint.

The contact's husband owns a 2020 Ford Expedition max platinum. The contact stated that while driving at 65-70 mph on cruise control mode, the vehicle inadvertently downshifted, skipped a gear and lurched forward several times. There were no warning lights illuminated. The contact stated that the vehicle would skip from 3rd gear to 5th gear whenever she would depress the accelerator pedal. The contact was able to continue to drive the vehicle. The vehicle was taken to the dealer who diagnosed that the transmission needed to be replaced. The contact stated that the vehicle was repaired; however upon picking up the vehicle from the dealer and driving home, the accelerator pedal was depressed but the vehicle inadvertently decelerated on its own. There were no warning lights illuminated. The contact also stated that the rpm of the vehicle was jumping between 2 and 3. The contact continued to drive the vehicle. The vehicle was taken back to the dealer who test drove the vehicle but was unable to diagnose it. The dealer reset the adaptive learning of the vehicle; however the failure persisted and the vehicle would make abnormal clunking sounds when switching gears to drive. The vehicle was taken back to the dealer who advised the contact that they could not duplicate the failure. The contact stated that the failure reoccurred increasingly and significantly while driving and the driver side rear brake had a strong burning odor. The vehicle was taken to a second dealer( lebanon Ford 770 columbus Ave, lebanon, OH 45036) who advised the contact that they could not duplicate the failure. The dealer notified the manufacturer of the failure. The manufacturer's field technician advised the dealer to replace the brake light sensors. The contact stated that the brake light sensors were replaced; however upon picking up the vehicle, the start button was depressed but the vehicle failed to start. The manufacturer was notified of the failure and offered a buy back. The vehicle was not repaired. The approximate failure mileage was.

At 70+ mph the automatic transmission tried to drop into 1st gear while on the interstate in a passing lane with heavy traffic all around. It had a loud and physical clunk then began to lose power. It was erratic, disorienting and distracting. The sudden change in behavior of the vehicle could have caused me to lose control of the vehicle at speed on a federal interstate and could easily resulted in an accident causing major injury and damage. The dealer says the car has no fault codes and they have download "updates" to the software. To date they have no explanation for why the vehicle behaved in this manner. This is the second time I have taken the vehicle in for odd transmission behavior. I have a video of the dashboard during the event showing the speed, rpm, mileage and the gear selector gauge when the transmission attempted several times to shift from higher gears to the 1st gear. I shared the video with the dealer. The video I have was taken with a iphone. It would not up load to your site. I can make it available. This is dangerous with no asnwers!.
