Stiff brake pedal at start, no audio?

[markitzero]

This morning I fired I fired up my ‘23 4v BW and dropped the kids off. No problem. Then when I started the car again the brake pedal was rock hard, and when I was driving I had no turn signal sound, and no speaker sound. Something must be shorted out, any idea/has anybody has this happen?

Scanned for trouble codes? Maybe a battery disconnect and reset if nothing resolves itself.

Did you have the wiring loom recall fix done?

No, it doesn’t show up in my Cadillac app as something that has been done or needs to be done. Any info about that?
