Odd sound

My month old 2022 make a “ffifft” sound at random times. It’s like a puff of air sound coming somewhere down by the drivers footwell. Could it be coolant pressure change? Magnetic shock noise? Lift issues?
Nothing on gauges shows danger but I’m ready to call dealer just in case.

Not to worry we all hear it. It’s the DFM system switching between V8 and V4 modes.

This is the correct answer. Next time you go for a ride, make a note of the V8/V4 indicator. When you hear the PFFFFT sound, quickly check the V8/V4 indicator again. It will most likely have changed.
