There are no current service bulletins for this issue on the base model audio units, usually this type of concern has a software update for a fix. Disconnect the battery for 10min then connect the cables again. If you should have a bunch of orange ABS lights on the dash afterwards don't panic, it's normal, drive the vehicle over 8mph in a straight line and they will go away automatically.
Sometimes the audio units just goof up like this, easy fix. If it keeps happening it will need a complete audio unit replacement.
