Anyone having issues with wipers activating when using the turn signal?

Slightly related but unrelated. I had a 2008 Colorado that would kick the wipers over once or twice randomly. It was some sort of interference in the wiring harness, GM put a bulletin  out for it, required a computer program tweak.

I have that problem on my 2024 2500. It’s random and I have been unable to reproduce it at will. I can grab the blinker stalk and jiggle it, lightly rotate it, etc and it won’t happen. I have a call into the service to get it checked. They are waiting for a loaner car for me first.

Just dropped my truck off at the dealer for this issue. I’ll report what they say.

The tech at the dealer thought initially that  I was using the blinker stalk wrong and pushing the wiper button until it happened to him twice during a drive with the service advisor. He ended up replacing the blinker stalk and returned my truck. I’ve only driven it about 50 miles since getting it back with lots of turns. So far no random wiper activation.
