Put gas in my car yesterday morning, 10 miles round trip. Came back home, parked the car and went about my day. Went to go out at 6PM and it wouldn't fire up. The idrive screen turned on and there was a Christmas tree of lights on the dash but the starter wasn't clicking.

Threw the battery charger on it last night (CTEK) and it says it's still charging this morning. I have a high capacity AGM in there that's only 4 months old....any idea's on what could've happened? Did the car get stuck in a loop and never go into sleep mode during the day and burn the entire battery down?

Edit 1:
I read a few other posts, and it seems like it could be bad gas, or that the fuel pump is shot. Hopefully I can get it up and running and it doesn't need to be flat bedded to the dealer.

Edit 2:
Battery Charger said the battery was fully charged after 18+ hours on the charger, Checked the voltage, and then tried to start it, fired right up. Checked to make sure it was charging and it was. What a weird gremlin I've got in my car.

Edit 3:
And dead again, up to the dealer it goes. This is super redic. Hopefully they can figure out what the issue is.
