Old Accord

I've just had a similar problem with a 2013 CR-V the wing mirror would not fold or tilt, also the security lights would not flash when locking. It seems to be the car management system that has cut them off. Disconnecting the battery and reconnecting has fixed everything but I also checked my battery voltage and it is below 12 volts and doesn't pick up even after a half hour run. I think the battery is getting old and the car is not getting a lot of use at the moment. Hope this helps.
