Loud high pitched whistling noise?

Does anyone else have this problem.  My 2007 Aveo makes this horrible noise when I am driving on the freeway.  It seems to be worse on windy days.  Sounds like it is coming from front passenger side.  Only starts at speeds over 60 mph.  Because I make trips back and forth to Nashville Tn to see family I find this problem very irritating!!  3 hours of squealing so loud even the radio cant drown it out.  I have taken it to the dealership twice and they said "we test drove it and didnt hear it so we cant diagnose it and we cant fix it"!!!  Any ideas???

Take it to another dealer for a 2nd opinion. If you're hearig it everytime you drive it, then sounds like the dealer was a litle lazy and didn't road test it well enough.
Its probably a weather stripping around the door that isn't tight enough. Could probably fix it with a door latch adjustment

Its hard to describe sound on the internet but we just replaced the wheel bearings in the front of one of our work cars 06 avoe after only 56K miles, but it was more of a humming noise???

weather stripping is probably the problem...if not check the brakes, because if they get bad enough the will make a high pitched noise even when they aren''t in use..

I also had to replace the wheel bearings at 60,000 miles on my 2006 Aveo. I realize that''s a lot of miles for a 2006, but other Aveo owners should take note.

Yeah I know what you''re talking about. I had an 07 aveo that did the same thing. It only happened to me when I was driving 85+ though. It''s not the bearings so don''t go and replace your bearings pre-maturely. If it''s the same thing as mine was it was a whistling coming from the passenger wheel-well. The plastic lining in mine was a little loose so it made a whistling noise when I hit high speeds. I just epoxied it down and it stopped.
