2016 Chevy Trax screen freezes, radio freezes and also does now keep programming
I’m not a mechanic but a couple of possibilities come to mind. You could have a weak alternator or battery. There could be a problem with the head unit itself. Or the body control module could be wonky but that would be a last option. An actual mechanic with hands on the vehicle can tell you more.
these might be of some help…
