One swipe wipers

[AngeloUCF]

Not being short, but after having many vehicles with auto sensing wipers I pretty much know that swiping on startup in a dry garage means something isn’t quite right and isn’t a setting…
Doesn’t do it every time, about 70% is more accurate…

Mine also does this quite frequently when on rain-sensing mode, and it hits the tennis ball that I have hanging as a parking assist. Oddly, I parked outside last night and it rained, but they would not turn on automatically this morning when I started the car, even after I drove off. I had to initiate them manually.

I mentioned this on a quality survey from Chevrolet recently. Let me know if you end up taking it into the dealer and if they do anything to fix it.

It’s not a malfunction, it’s the setting you have them on. When you first start the vehicle they will operate based off the intermittent section when the wipers are set to auto. If you choose something other than inter you won’t have that issue on startup.

Have you checked the sensors to ensure they are clean? Sometimes it takes more than a car wash bath to get them clean, due to the small area that can occasionally get clogged up.
