Computer Failure problems of the 2017 Toyota RAV4

When it is raining, or snowing and for some reason, the sensors get wet from the bumper, crosstraffic alert or backup or side warning, the whole system shuts down. Driving on the freeway and it is raining and the whole computer just froze, and lost all sensors and a failure alert showed up on the dashboard, along with the cars transmission have a hard time shifting as exiting the free way. This is total computer failure but after exiting the freeway and driving down a road, and at a stop light put the transmission in neutral and shifting back to drive, all the computer errors cleared. Took it to the dealer and of course they found nothing. This is dangerous for blind spot warning sensors to go out the pbm sensor said failure and there is an electric harness issue with this car where the wires either were not insulated or nick along with the computer model to the transmission. There is faulty insulation, this happens only on occasion and not all the time, and every now and then there is a computer issue, the clears itself. Also the clock was losing time. Due to the electrical issues this is a safety issue,. When everything shuts down when the car is being driven is a safety issue. Yet, shifting the transmission cleared the errros off the dash.
