Just took delivery on a black AWD RS with all the bells and whistles and can't wait to get her out on the road. Hoping it gets better MPG than my previous 2018 Jeep Compass Trailhawk got (14PMG!!). Just took it for a little drive down the street there is a faint whistle like noise, you can hear it when the car is decelerating most I think - should I be worried? Or do you think it's something that might go away once the car is broken in a little? I guess it could be the breaks working or something, but it happens before I even push the breaks. The guy who delivered it said it could be the turbo taking in some air though, but I honestly have no idea. Would love some input if anybody has any! Looking forward to being a part of this community!
