It really irks me that a Hyundai i40 or Nissan pulsar sedan are quieter than my car
Do you have wind noise as well or just the road noise? I have wind noise that becomes obtrusive over 45 mph. If I hold a glove or towel in the upper rear corner of the side window, along the b-pillar, it isolates it nicely. It is the same on the passenger side as well. My dealer is aware of it, but I suspect nothing will be able to be done to fix it, especially at this location. I don't see any gaps or anything that would lead me to believe an adjustment of any type would fix it. I believe it is just an inherent design flaw. I am going to try to get something manufactured to fit in this area that doesn't look as obvious as a towel duct taped to the window.
