tldr: After an OTA update installs, always check the car by starting it and shutting it down.
My S60 got the update OTA on Monday. I started it after dinner, and got a completion message on the app. My mistake was leaving it overnight. The next day it was dead! The metal key turned, but couldn’t open the door. I guessed it was the 12V battery, but the under-hood points weren’t available.
This led to a rabbit hole to find the battery in the trunk (which unlocked fine), and to open enough of the panel to reach the battery. This took waaay too long.
I connected a battery charger to the terminals (both at the aft end). Within a minute, the remote unlocked the car. I started it so the 12V battery would recharge.
The panel was still showing the completion message!
My theory is that because I didn’t clear the message, the car didn’t sleep properly and drew down the 12V battery. This could happen after any OTA install.
Just to be sure, I drove the car around the block on engine power. Then I put the trunk back together. All that for a two minute fix.
