So I get my rx350 and notice that it was loud in the cabin like if a window was partially opened , couldn't figure out what it was. Took it through car wash of course I make sure everything was closed including sunroof and it starts dripping on the inside at the rear if sunroof where the rubber was. Would explain the noise too if the seal broken. Anyone else have this problem?

No, my sympathies. Your dealer should have checked it before delivering the car. Didn't they notice when they washed the car???

Inside the channel around the top are two drain holes; these drain the water through rubber tubes (downspouts) that empty to the pavement under the car. A sunroof leak is often caused by a blockage in this drain system. Pour a little water into the trough and see if it drips out under the car.
(PS: I might add that this is based on prior cars I have owned. I am presuming that the RX has the same system to get that water out, but I have not had this problem in my RX, and I have never even looked for the drain system.)

Like "tfischer" said above with drain holes. If you park your vehicle outside especially where you have heavy pollen, you may have the drainage cloged up. I have this problem with Miata which is parked inside at home but left outside under a tree at work and pollen and leaves will clog the drain hole so it requires regular cleaning to prevent water in trunk and/or inside the cabin.
