    I have a 2012 Volt (56K mi) and I just got this dreaded message (Service High Voltage Charging System). The battery coolant level is at the half-way level, right above the top of a white sticker on the side of the container. If I've read the forum messages carefully, that's where it should be.

    What should I do? Is my only recourse the local dealership? What should I tell them, and what should I expect? Should I have them replace the coolant? And should I replace the sensor (WopOnTour) so this can be avoided in the future?

    Thanks,
