Noticed that water was pooling behind driver's seat on the floor and saw some running down side of rear seat. Thought it was a door seal leak. I also saw water droplets coming out of vent in cargo area. Thought water was somehow getting into heating vent system.

It turns out neither were true. The dealer identified that the sunroof leaks on rear corner. Water drops directly down onto side of rear seat and pools on floor. It also runs behind headliner and wall panels to rear cargo area and comes out of the vent on the wall. That vent, they tell me, is only decorative and not linked to heating ventilation system.

So, entire sunroof must be replaced. Big job. But, it's covered by warranty.
