I bought a used 2018 WRX about 2 months ago. Had no problems until now. Something is draining my battery. The owner before me upgraded to a stage 2 perrin with the Cobb AP. I unplug my AP every time I get out the car for the day or even on the weekend thinking it might be draining it. By Monday the battery is still dead. The battery was bought in Feb this year. Had it tested at Autozone and it passed. Any clue what could be doing this? Or what I can look for and test? Thanks.
