no leaks here..but sometimes it gives me a hard time closing it..but sometimes..

No leaks so far but My roof blew up instead
 

There must be something with these roofs. On my car the sunroof never leaks but a few weeks ago when driving on a cold day over a mountain pass the main panel of the roof just blew out. There were no cars ahead of me so it was definitely not a rock that flew from in front of me.

The dealership replaced the cassette and so far I'm in luck.

Mine leaked too
 

I took it in to be serviced, and they did not fix it the first time, in fact deleted that from the service ticket.

Brought it back, and they replaced the gasket - took 2 weeks, and the new sunroof was incorrectly installed - the bellows were bent and ripped the first time I opened the roof. And the paint on the roof was cut through to the metal, apparently in the attempt to remove the gasket. And BTW, the roof still leaked (into the rear storage by the radio).

The third trip to the dealer for this problem resulted in a replaced sunroof cassette and a new paint job. All was fixed.

I have gone through the wash a few times and on the high powered blow dry system I will occassionally get a little spray through the sun roof. No big deal given the power of the dryers.
