For the first time today I heard a distinct "whooshing" sound when I accelerated my 2017 Tucson 1.6T, hi/low speed did not seem to be a variable. The car has ~25k miles on it. I've read similar concerns regarding the Sonata 2.0T. I'm calling the service department first thing Monday. Thought I'd reach out the forum as well. Helpful insights are appreciated. Thanks!
