I've got the same problem, and the dealer thinks its do to dirt/leaves tht get into the weather seal track, and or clogged tubes in the sunroof (which they cleaned out in May). The cargo area carpet is soaked, but the water also travels to the front carpets due to driving/braking. has anyone else found a solution, and/or gotten the dealer to cover the cost?
Thanks
Had similar problem with my 2000 LX. Dealer replaced seal around RHMSL(Rear High Mount Stop Lamp). Water was traveling through the light down the trim and onto my rear cargo carpet. Mine was under warranty so they replaced it free.
