I have a 2012 dodge charger sxt it has 140,000 miles on it and for the past 2 yrs I've been dealing with a battery drain that neither an electrician or even a Mopar dealership has been able to figure out. It use to be an every once in a while thing where the battery would be perfectly fine without draining for say half a year, then it would drain and keep draining for a period of time about a week straight and it would be fine again for a while. I've gotten a new battery and the issue is still there. As of right now the problem has been persistent for more than a month now. The way around it has been to get a kill switch but no real fix. Would you happen to know what it could be? I know you've dealt with chargers before so wanted to see if this has ever popped out for you. Also I forgot to mention that the alternator is good according to auto part stores and the dealership.
