Has anyone had a problem with their sunroof making a dragging/slipping noise when opening? This happens only at the very start of the open/close or tilt open/close. I have noticed it happens when it is very hot outside, above 80/85 or so. The hotter it is and the longer it has sat in the sun, the louder the noise and the longer is lasts. It appears that the seal may be swelling and causing it to drag. I took it to the dealer, and he said he heard the same noise on two other cars on the lot (not just RX330's) , but was still unable to diagnose the cause. I also live where it is extremely humid, so this may be a factor. This week it was noticeable every day (we were in the high 90's) but today it dropped to 75 and no noise.
