So my car has been parked out front for less than 2 days... (decent drive on monday night, and moved it yesterday to shuffle the cars in the driveway) Just now the dogs started barking to what sounded like a paulsy victim playing 'Operation!'... Upon closer inspection, it turned out to be the Aurion which was emitting an erratic beep, in no particular rhythm, which sounded like the horn, but much much much quieter. My keyfob would not unlock the car, so i had to use the key, and as soon as i unlocked it, the beeping stopped. I closed the door again and tried out the keyfob which worked just fine. I then tried to start it, and what do you know.... nothing. The car didn't even 'tick over' as cars do when their battery is going flat. It did absolutely nothing. The dash lights still work when the key is turned but thats about the extent of it. The battery did run down last week due to the doors being open when i detailed the inside. Which i found to be odd, as the MAYBE 4 hours that the doors were open, i wouldnt think it would drain the battery. Is this just a sign telling me i need a replacement battery? Had it 2 years now, and didnt think it should already need replacing. OR is this something more serious? I will try to jump start the car once this bloody rain subsides, but for now, can't do much but search for information. Cheers for any help guys.
