But when she's out, like today in a car wash, shell try and restart and it will be COMPLETELY dead. Like barely clicks. So it's being drawn down in under 10min when it happens.
It's not all the time and I'm pretty sure the alternator works. I've seen a recall on a CANBUS issue that creates a big parasitic draw but that was 2015-2020 models.
Any ideas or thoughts?? She doesn't run heated seats, stereo, etc and is now basically done with it. So I get a new toy (M40i elec?) We've got it at ALL Makes today.

I once had the switch/sensor (probably not the correct term) on my brake pedal go bad. Basically the vehicle thought the brakes were on all the time and the brake light stayed on even when the pedal was not depressed. It would kill the battery after sitting all day/overnight at work. Maybe something like that, although that doesn't seem to be enough of a draw to kill the battery in a few minutes.
