2011 Genesis Sedan Dash Lights on

[Michigan Hyundai]

I have a 2011 Genesis sedan. Runs great though a week back most of my dash lights came on particularly brake systems lights and they won't go off. Parked while running then all of a sudden it stopped. Waited a few seconds it started again and drove home. Dash lights would come on again when driving. Took it to the dealer and had full electrical diagnostic check $300 +. Told it was some "can system" needs to be replace at the cost of 6k. Read some threads about resetting the negative battery cable and trying that. Has anyone had this issue? Thank you for your insight.
