I have the EXACT same issue with my LS. I have not tried to fix it - yet, but I would hazzard a guess that the rubber that the windows touches when the window is closed, has dried up and hardened ( maybe shrank ( is that a word ? ) ), so instead of holding the window firmly, it makes noise when the window moves around and lets the air in too.

.... ahhhhh hem, Chris, that is my theory - which is mine ( borrowed from Monte Python )

Some rubber conditioner may fix it - or some sort of extra (thin) soft rubber strip attached to the old one is what I'll try, unless someone knows a better solution

An old thread, but did anyone find a permanent solution to this?

There is probably no solution to old age rubber. Left exposed to the sun continually to the ambient cliamate and SUV exposure, there can be little doubt but what that the rubber will deteriorate. This means the rubber will become hardened and less able to form a seal to prevent wind noise. If the car is garaged and/or covered during exposure to the daylight sun and environment, little can be done to prevent eventual deterioration.

My car has always been garaged and the rubber and interior is in excellent shape, near original condition. I had a 1992 SC400 which I convered with a car cover while at work every day that it was possible. That kept the car in excellent condition for 20 years.

There is no such thing as a car that is designed and produced to remain in perfect condition forever!

I have used this on my Avalon with some success. It reduce the noise some, but not 100%.

Lexus engineers were outsmarted again, with a more cost effective solution! I use clear packaging tape myself to hold the car together, namely the pass side drip rail.
