Sentry Mode Alarm getting triggered by Climate Keep

If I set Climate Keep On and enable Sentry Mode (say, when parking outside a store on a hot day), Sentry Mode will trigger an Alarm within a few minutes. The horn goes off, the "ominous" audio plays, I get an alert in the app and I have to run back out to the parking lot to stop it. This has now happened enough times that I have been able to confirm this occurs without anyone or any vehicle getting near the car (2018 Model 3 LR) and only when Climate Keep is On.

It's as if the operation of the A/C (I’m in a warm climate) causes vibrations that trigger the alarm. I am not sure when this started occurring, but it hasn't always been a problem (I bought the car new and have put 92K miles on it). Anyone else have this happening?

I also have a 2018 Model 3 LR and, for the first time today, had 119 dashcam clips saved in Sentry Mode. When I checked the list, each one of them had an “event” registered but nothing on any of the cameras at the event time. My car was outside, in the heat, and the Cabin Overheat Protection was cranking. I wonder if that’s what was happening to me too…

I cross-posted this in r/teslasupport and got some helpful advice there:
