We've had our 2015 LTZ 4WD for a week now and I've noticed the air pressure in the cabin bothers my ears (all windows and doors closed). This is particularly noticeable at highway speeds. I've never had this occur in a vehicle before. Have tried using climate control on recirculate rather than fresh air but no luck. Does anyone know where the air exhaust vents for pressure equalization are in this model? This thing is sealed up a little too well for my taste.
