I occasionally have an issue where the car's Bluetooth media/phone connections are active even while the car's off. I first noticed this while having trouble taking a call. If I check the Bluetooth settings, it'll show it's connected to the Model 3. Bouncing the Bluetooth connection has no effect, it'll connect right back up again within a few seconds. The issue tends to last for an hour or two, but I've seen it last up to four. If I go out and look at the car, there are no signs of it being awake (it's locked, screen/lights off, no fans or other noises, sometimes plugged in/charging, sometimes not). I work from home, and sit ~ 5ft from my car 8-10h a day, and I notice this issue probably at least once a week. It also doesn't necessarily correspond with a recent trip- last week, I hadn't driven the car for two days when it happened. Anyone else?
