I had the same problem yesterday with my 2012 Civic ex, I read many many forums in the 45 minutes it took me to restart the car at a random parking lot.
3. Replace the battery. These you can do yourself for under $150.
If it fixes it, great, otherwise it will require professional work.
Did you actually replace the battery?
Same (kinda) happened to me: the car was stopped and unused for few days. Tried to start it, dead battery. Went to Autozone and they charged and checked the battery. Come home and all alerts popping in.
So apparently just driving it around should make them disappear?
Latter edit: YES, it did. LOL.
