Ever since I bought my 2004 ES330 six years ago, there's been a mild wind noise. The wind noise occurs when traveling about 55 mph or more on certain days, presumably when the wind hits in a certain direction, etc. The sound comes from the sunroof area and sounds like the sunroof is very slightly open.
When I go to my local Lexus dealer for regular service, I ask them to look at it, but they've never been able to get rid of the problem. When I look at the way the sunroof aligns with the roof, it looks pretty smooth to me. I can't figure out what could be generating this noise. Is this a design defect? Am I just wasting my time asking them to fix it?
