2022 BMW M235I

According to the dealer, a transmission sensor underneath the gear shifter got wet due to a liquid spill from the cupholders. While driving on the highway returning from scheduled dealer maintenance on the car, the informations screen showed a warning that there was a drive train malfunction and that the car would not be drivable after the current drive ended. The cupholders were not in use at this time so the spill must have occurred earlier, the fault apparently did not occur at the same time
