My car has been at the tint shop since Monday. I pick it up tonight and see an envelope in the corner of the navi screen. The 2 msgs were low batt and ABS and VSA were not working because of low batt.

I drove home fine and don't seem to have a low battery and VSA light was not off. Has anyone experienced this? Do I need to worry about this?

 

Its up to you if you want to worry about it or not.

or

You could go and get your battery tested to see what charge its holding and pay attention to any indications of a low battery i.e. slow crank start, dimmer lights, etc.
