I have a draw somewhere, the original battery died when it got cold. Replaced it with a x2 h6 battery and it died in 2 days after install. Alternator was charging at 15+v and had to jump it every day. Took it out because it seemed like I bought a bad battery, batteries plus test it and load test it and it works perfectly fine with them. I purchased a autozone duralast h6 agm platinum and it made it further than the X2. Sat overnight at the dealer this morning when they went to look at it the battery was completely dead. I can not figure it out, neither can they. My Cobb tuner cord is pulling a 5 mili amp with the accessport unplugged. Which isn’t enough to completely kill a battery overnight. The alternator is fine according to them and so is the starter. Is there a common issue that I’m not able to find or??? Please help!

you getting deep sleep notifications as well or does it just die. Early 2020s have had issues with deep sleep and module firmware updates was the solution. But if this is a recent thing, you might have something else going on. i would keep it on a trickle charger for he time being as you are going to kill your new battery letting it die. I would also make sure you are on Sync 23188 and turning off wifi, auto update and anonymous feedback. Lock the car when parked at home.

I get a mixture of deep sleep notifications and none at all. This last time it died completely overnight. I have uninstalled the tune and tuner as well to see if that was causing the issue. I’ll also do the WiFi and all as well. I lock the car and place my key on the far end of the house.
