[ODONO]

Hi all thanks for letting me share my problem I have a 2020 3.3 GT problem I get is between 26 and 29 mph I get a buffering sound in cabin sounds like air? like sometimes when you have a window open and you change the air pressure it buffers only way I can put it, car only done 1500miles not damaged tyres or hit anything also does it if I open a window, wondered if its the new 2020 exhaust please anyone had same problem many thanks.

Welcome to the Forum. My arrival here was to ask a question as well. Only between 26 and 29 MPH? That's pretty narrow range for annoying noise. Some kind of "harmonic" is established right at that point, in your particular vehicle. Just be glad it isn't a rattle, squeak or knocking sound, and continuous!

Did you also disable "smart ventilation"

Thanks ShannonC went in to AC setting and disabled smart vent, buffering noise still there
