Software problems of the 2019 Toyota Highlander

I bought this car new with about 11 mile on it. The transmission immediately had shifting issues as it could not decide what forward gear to go into and shifted hard and felt as if it was going into two gears at one time and after a short drive the instrument cluster warning display indicated a check engine light and warning that the transmission was overheating and acted as if the engine was starving of fuel as it surged and did not deliver power to go beyond 35 mph. After I bought it the dealer reassured me at least three times that the car was okay and that this is the way that the transmission shifts. I repeatedly had the dealer check it and the dealer reassured me that there was no trouble code and no problems found although the check engine light was on and the instrument cluster showed transmission overheating and they fixed a wiring connector to try and fix the running problem. A class action suit came out for the fuel pump failure recall and the 8 speed transmission. I feel that this is a very common problem that the dealer and manufacture are trying to hide. After 13 months and 2,800 total miles the transmission overheated, burned up the internal clutch set and I now have no forward and reverse gears. I feel that the surging and transmission problems are a software defect as the shifting defect comes and goes and vastly promoted if I drive it very gently from a cold start. Once warmed up it does not act up as often except when two gears seem to be engaged at the same time. The key also intermittently does not allow the car to start and instrument cluster also shows trac light , abs failure light, bsm not available, Smart key failure, and complete black out of the instrument cluster and shown to the dealer mechanic and service writers and photographed and videotaped for documentation and in the repair orders.
