I have a 2018 Chevy Traverse High Country with side collision temporary unavailable message on the front display. My Traverse is clean and garage kept. Of course this issue started a year after the warranty ended. The dealership wants to charge me $600 to trouble shoot. Not to fix it just troubleshoot. I purchased the Haynes repair manual but nothing in there. I figured maybe a fuse or something simple but nothing. we live our 2018 Traverse. It only has 60k miles.
