2011 w/ no leaks to date.
The leaks seem to be caused by the drain tubes becoming clogged and causing the water to back up. A yearly snaking out with weed whacker line or blowing them out with compressed air on vehicles that have leaks seems to be a good solution for many.
As said, to date mine has not leaked. I have had the a-pillar trim off and the tubes are clear so I have not done anything to them. I am not touching them unless a leak happens. Leaving well enough alone.
Note - I routinely take my Patriot through the local touch free car wash with it's very high pressure rinse. No leaks there either. I have even had the headliner tray slid back so I can look around the sunroof to see if any water gets in and it is always bone dry. The only time I have had any water get in is when I accidentally left it in vent mode when I went inside and it started to rain. Luckily I had the headliner tray closed so no water got inside the vehicle.
