Another update... Dealership is replacing the fuse box. Said there was a bunch of water and corrosion in it. I'll get it back in a week and will provide another update.
Just wanted to add more information to anyone looking with this same issue. I ended up replacing the battery, issue when up getting worse within 2-3 weeks of the new battery. The turn signal works about 20% of the time.
Any update on this? My 2017 started doing this last December when we were visiting Ohio. It hadn't done it all spring/summer and most of fall since then (we live in Florida). Just noticed this happening again randomly now that the weather has cooled down.
