Anyone else with a 2020 Sierra 2500HD experiencing excessive noise from the cabin pressure relief vent(s) and if so is there any fix to tame it down a little bit? I realize it's not a lexus but I've never owned a truck with so much road, air, and exhaust noise from cabin vents. My expectation would be that it's always as quiet as it is when the recirculator is on.
