Hi fellow Cube owners. I was driving on the freeway earlier today and noticed a high pitched noise. I turned off the radio and noticed the sound appeared when I drove at least 70mph. Driving slower than 70 and the sound would disappear. The sound is very annoying now that I notice it. I was thinking it might be wind noise coming from the windshield. I'm hoping it's not the engine or something serious. Maybe it's part of the breaking in process. Any ideas? Has anyone else experienced this problem? Thanks for the help.
