Problem with 12 Volt Battery in 2016 Prius 4 Touring

Another update. After the last time this code issue had come up and all the dealer did was reseat the connector at the ECU and the right rear wheel sensor we went over 10,000 miles without an issue. Unfortunately this past week the same warning messages and codes came back. Not certain if driving in wet weather conditions impacts this or not. The warnings came and went several times while we were heading to the closest dealer. Unfortunately with no appointment and. Holiday weekend they would not be able to even look at it until the following Tuesday. The war went away, but I am taking it in to the dealer on Friday. This is the fourth time and my patience has grown thin. We will see what the dealer says, but I need a car I can trust.
