I just had the same problem this morning. Went out and my dash said my door was open, my seatbelt wasn't on (it was) and my lights went out. The controls for the radio on the steering wheel went out too. I pulled the neg terminal from the battery for about 30 minutes and now my radio says disable, which is going to make the drive home fun as hells.
I'm going to autozone to pick up the Duralast 49-DL at lunch today and will see if that fixes the issue.
