My 2013 Sonic over night started this. I started it and the radio is black. Will not come on. The turn signals won’t work right. No buttons on steering wheel work. And the cluster goes in and out with some lights flashing on it. What could it be I check alternator and it checks fine.

I would check the battery by doing a load test. Even then, a weak or intermittent dying battery can cause all sorts of weird issues.
If you have or can get a GOOD stout battery charger . . put that on for a few hours.

Also, check the battery cable connections for tightness and corrosion . Maybe evven disconnect and clean the battery and connectors. . . . . especially the Negative cable and

Hey. I tried everything. Battery is good. Posts are clean and good contact. And still doing the same thing. Anything else to check or anyone else have an idea ??

A bad clock spring in the steering wheel would cause that.
