2021 Cadillac CT4 V
I am 45 days into owning a CT4 V non BW. Some issues i am having is the cel is coming on after a couple hours driving on the interstate, intermittingly on startup i get the sound of a toilet flushing followed by a knocking noise coming form the center console/firewall area and slow speed brake noise not squeal. Any thoughts would be appreciated.

TY
