2016~2023 Slow Draw Because of Water on Lift Gate Sensor

My wife tried to start her 2016 CX-9 yesterday and it wouldnt start. A bunch of dash text flashed on the right gauge and the infotainment screen wouldnt come on.

It turns out the battery was dead, because I was able to jump it.

I took it to the dealer and they tested the battery and said it was good. But they know of cases where water on the lift gate sensor will cause a slow draw on the battery.

Has anybody else experienced such an issue? And was it easy for the dealer to resolve?
