Quick question (as in a response within 10 minutes would be nice) in looking at a brz, and on the test drive I noticed an occasional hissing sound, like escaping air, coming frm what sounded like just under the center of the dashboard. The ccar is pre owned and has the balance of factory warranty, but the cpo warranty is powertrain only. Is this something I should be concerned about .

God, kinja mobile feels like communicating with a vegetable.
