It's going in for warranty work in a week. They ordered new front and back cameras and the cable that connects them. I'm not convinced that will solve the problem but we'll see. I'll circle back after the work is done.
For what it's worth, they will also be addressing the wipers going on when the feel like it (yes, even when the wiper is in the off position), as well as a U0285, code which is a lower grill shutter fault. I cleared that code and it comes right back on after next start up, which stinks because remote start won't work and I live in Michigan.
