It's moisture related. Causing intermittent connections and a short/ overcurrent.
Error Likely a red herring the front bumper cameras are the most prone.

Remove screws holding flap between wheel well and bumper... push tab on harness that connects to side view camera and disconnect harness. Use hairdryer to remove moisture. Reconnect harness and refasten flap. Repeat for other side. Reconnect and test cameras.
This is after dealer tried to fix 5 times. 4 years in a row. Acts up every time when weather changes. Dealer is giving me excuses after car gets into extended warranty period. Decided to fix it myself instead.
