So ever since I bought my skyactiv almost a year ago I've been hearing wind noise right behind me(rear drivers door somewhere ) especially when driving at faster speeds. At times its so loud that it sounds like the window is slightly cracked. At first I disregarded that thinking that I get what I pay for ( thinking its no BMW or Lexus) but I now drive more on highway and this is getting annoying. Has anyone experienced an issue like that? No weather seals are damaged or anything. Should I take to the dealership in hopes they repair under warranty? Just don't want them to make it worse.
