High Pitch Whistle above 70 mph
When I hit about 70-90mph I start to hear a high pitch whistling noise. It only happens when I'm accelerating. I could hear it the loudest when I just barely tap my gas pedal and as well as when I'm on cruise control. Sounds like it might be coming from the rear but not 100% sure.
