Air conditioning unit stays on after exiting vehicle

Most likely a bug in 16.2. Anyone else noticing it?

I made sure that the option to keep the climate on is set to OFF. I’ve noticed on several occasions, the AC does not turn off even if you exit the vehicle and lock it. This is especially true if I’d set it on via the app before entering the car.

Just be careful and make sure that you’ve manually turned it off either before exiting or via the app right after exiting. Don’t drain your battery by mistake.
 
How long have you seen it continue to run?

If I see that it didn’t turn off as soon as I exited the car and locked it, I manually switch it off right away, so I guess for half a minute or so. I never waited longer than that to see if it turns itself off. Previously It would always turn off right away but I’ve been noticing since 16.2 that it stays on.
 
I definitely experienced this last night. Here's the thing - the A/C didn't stay on. It turned on all by itself!

I got home and exited that car. I wasn't using the A/C.
After twenty minutes, I went back into the garage, and I could hear the compressor running! I opened the door and manually turned it off. I don't believe it turned on again for the rest of the night.

We have experienced this recently as well too. I can only surmise it is battery cooling as it has been hot here in FL.
 
This has been happening for me even on my last 2 firmwares (12.1 & 12.2). It doesn’t seem to be battery cooling at all because it has happened even at very mild temps in the 50s. Also it’s a completely different sound and a different location from the battery cooling fans.

It sounds exactly like the AC running. You can even place your hand in the area where to AC intake is and feel the airflow. It is also random, I have parked the car in the garage not heard the fan and then came back over an hour later to here it running. I’ve also heard it running and continuing to run immediately after I exit the car and close the door. I’ve never timed how long it runs, but it seems to be awhile.
 
A short cut for those that don’t know, press and hold the fan icon for a few seconds and it turns off the A/C and blower.

Helpful but not relevant to this discussion. Switching off the car means everything should switch off on its own. It was working perfectly until now. And now it doesn’t.

Also, Battery cooling has nothing to do with cabin A/C.
 
I have a feeling this is working as intended. To me it’s just drying out the AC system after use in order to prevent the musty smell you sometimes get in other cars due to moisture build up in the system.

Although I don’t know how long it runs or what triggers it I know it’s not getting “stuck” on and running continually because it always stops on it’s own for me. Also if you quickly open the door and place your hand in front of the interior vents it’s not actually blowing air into the cabin. You could also test this by leaving the window down and feel that nothing is blowing into the cabin I guess.

I noticed something similar a day or two ago, but at the time I had manually turned on AC while in BT range before getting in to drive somewhere and then after being out of the car for 30ish minutes I walked by it and noticed the fan was going. Opened the app and saw that the climate was on so I turned it off and the fan stopped.

I'm not sure if it was from walking back up to the car, or if it got into some weird state that it thought I wanted the AC on from when I first got in.
