NHTSA Complaint #11425589 — 2020 FORD EXPEDITION

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 answers!
