Interesting question, not sure mine is washed any special way, I know it's not washed too frequently but does go through the car wash. It is stored outside but I live in Southern California and we have very little rain.
I just had this happen to my 2023 for a 2nd time - walked around my truck to see my white tail lights half out and flickering. Upon closer inspection saw half a centimeters of water sitting in the lights. I'm also getting an error on the dash about a "charge leak" that im guessing is related...
