Every time I hand wash my 03 TLs I notice a small puddle of water on the center of the rear seat. This does not happen when it rains. Best I can figure the water must be comming in near the nav antenna, although I don't see any moisture anywhere on the inside of the roof. Has anyone else noticed this?

 

How about taking it to the Service Dept?

 

That's some weird $hit....defin take it in.
