2017 Volt “service high voltage charging system”

Postby Patjws2017Volt » Sun Oct 28, 2018 3:27 pm

on a trip to the outer banks when the message “service high voltage charging system” popped up and the check engine light came on. I looked it up and seemed likely related to the high voltage battery cooling system, so I checked and found no coolant visible in that reservoir. Also, we did have very heavy rain while there.

1st question - is it safe to drive it until you can look at it?

Anyone else have this problem?
