I have the same issue when cold and snowy/icy, even in heavy rain sometimes.
The system disables itself as Jwithing said. I also have a long paved driveway and I typically back in and the system also doesn’t work if you reverse over a few MPH - it tells me this as well. That said, I do appreciate the sensors and use them when parking in unfamiliar areas where I don’t normally park. Anywhere I normally park it’s more like muscle memory for me, and I’m still an old fashioned rear and side mirrors guy as opposed to using the rear camera. My kids make fun of me because they all use the rear cameras in their vehicles now. [emoji1]
