I have a 2012 Volt and a 2014 ELR. If you have seen my earlier posts, my 2012 had a lot of charging issues that turned out to be a bad BECM. Essentially, the contacts on the board are vastly undersized for the job they need to do. Well, a little over a year later, the 2014 had the same issue. I would recommend that anyone experiencing wonky charging issues with their Volt/ELR DO NOT ACCEPT the dealerships answers when they say it needed a "Software update" or it was a transient issue that cleared. MAKE THEM PROVE TO YOU it's not the board!!!! I can't stress this enough. The dealership techs have no idea how to repair these cars and they just call TAC. I am now in the market for a new battery and have sunk nearly 3k in the ELR and I still can't charge. The dealership model is a relic of the 20th century. No upgrades, no skills, just sell you a new car! Pics attached:
