When I arrived in the parking lot and selected the R (reverse), the vehicle stayed in the D (Drive) although that it was moving backwards and was able to park it. The shift selector was stuck in DRIVE (Drive) leaving the vehicle on but not operational. After several attempts to allow the vehicle to cool and the battery to reset, (30 minutes_ later), the car started and took the vehicle to be serviced. The vehicle technician said they had a difficult time diagnosing the vehicle because it was giving different codes. They said that while testing they found the Transmission Shift Selector Module was damaged. Not physically but electronically damaged. They also stated that the car could have other problems but that they needed to replace the module first because it could be the cause of the other errors.

Incident sounds similar to those experienced with the dual clutch transmissions. November 2022, all of the vehicle warning lights were on and remained on. The vehicle would not move and the transmission selector/shifter was locked in place. Working with the local service/dealership, the vehicle was repaired after 3 weeks with a new transmission shift actuator (or possibly other part). Similarity in the experience and possibility of risk with little information about trends or others in similar situations or resolution. We've had another (Same make/model/year) vehicle present similar circumstances.
