Very active HV contacts

In the past couple weeks, I've noticed the HV battery contacts clicking a lot more than before while my car is plugged in and sitting in the garage - like every few minutes. Before I'd only hear them when starting to charge, or if the 12v battery needed to be topped off. My 12v is only 3 months old so I don't think it is about to fail, though I'm not sure what else it could be. Phantom power drain has remained fairly constant over many months.

I found a model 3 thread regarding the HV contacts clicking a lot while plugged in, and the report from Tesla in that thread was that this was a new bug in the firmware and would be corrected in a future version. Same issue across all models maybe?
