Anyone else hearing these random subsonic BOOMs while sitting quietly parked with HVAC running (camp mode)?
When it's happening it is one boom every few minutes or so, and I never know when it will act up. I would say It is more felt than heard. It is a very low frequency impulse that sounds like an explosion somewhere nearby shaking the ground. After the initial impulse I believe I can hear a brief rush of fluid or gas for second.
I've been following this for a few weeks now to try to determine under what conditions it happens but nothing conclusive yet. I did notice that by changing the temperature setting on the climate control I was able to make it stop a couple times, so I suspect it is related. Perhaps some sort of pressure release from the heating/cooling system?
I've read about the accounts of noises from the battery case expansion/contraction, but I don't know if that would account for the associated fluid sound. It sounds like a burst valve is opening to blow off pressure somewhere.
