Warning problem #1

Radio, hands free calling, and light on mirror shorting out. None of them work. It’s like it has a short in the wiring.

Blind Spot Detection problem #2

It starts to “warn” you by the seat doing whatever it does and the dash lights up collision flashing and slams on the brakes when nothing is even around.
