I've been having troubles with my 2013 C-Max Energi (this model has since been discontinued). Before InsideEVs forum, I found the forum at fordcmaxenergiforum dot com particularly useful for this vehicle. The website no longer appears active... anyone else wondering where it went??!! I had so many minor issues solved there with the help of the C-Max owners. I woke up to a completely dead car this morning that wouldn't turn on. Waiting for my buddy to get home so I can borrow his volt meter & battery charger to find out what in the world is wrong... I fear it is the dreaded & known 12V issue.
