I have a 2012 Volt with 59K miles on it, and I haven't had a problem with it until recently. About two and a half weeks ago, the check engine light came on. I don't have Onstar, so I don't have codes for anything here. Anyway, I took it to my dealer, and they replaced part of the charging system, which included tightening the charge door. I would be more specific but can't locate the paperwork stating what they did; I must have misplaced it in the Christmas rush.
So on the drive home from picking it up, I get the "battery too cold, plug in car" message, which I found from searching relates to temperatures much colder than I was driving in (which were in the 30s - I'm in the Detroit area). I took the Volt back out again a couple hours later, and the engine light was back on, and the battery too cold message popped up once or twice. So I took it back again. The service folks told me the next day that they'd have to order a part from GM, as they'd never seen this issue come up before. A week later, I pick up the car. This time, the problem was diagnosed as "hybrid battery section 2 - temp sensor 6 failure," and they replaced that battery section.
I picked up the car Monday, and the the temps were not cold enough to start the gas engine until yesterday. As soon as the gas engine started, the check engine light came on, and has not gone off since. This is getting a bit frustrating. Anyone have anything remotely like this? The car has run and charged normally at all points since this started, so far as I can tell. If the engine light had never come on, I would not have been able to discern anything wrong with the car.
