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.

My wife's Outback was doing similar things for about a year. I would take it to the car wash and then out of the blue the idiot lights would turn on and the car wouldn't turn over. 15 minutes later all good. It then happened to her months later at the grocery store parking lot. The battery was recently replaced and fine so we took it into the dealership and they found that the intake piping was not properly fitted after the air filter and it solved the issue. What ticked me off is that the only people that touched the intake plumbing was the dealership as they clearly didn't re-assemble the intake properly after last changing the air filter.
