Hello. I own a 07 Cadillac Escalade ESV and I bought it used in 09. I had a one time issue five months ago with the battery going dead after 3 days of not starting the car. I Jump started the car and it seemed okay for a while. And then recently I haven't started the car in about a month and I found the battery dead again.
I'm not very experienced in fixing cars but after doing a little research online it seems like the car might have a electrical drain by a component in the car, or a problem with the alternator (although probably not). I plan to try replacing the battery with a new one and seeing if the problems occurs again.
What would be the best step to take? I read online that for many, the dealership had hard time finding the electrical leak and since my problem occurs inconsistently I thought replacing the battery would be the better option.
Any advice would be appreciated.
