I noticed today that I had standing water in my rear passenger Floor board. So I vacumed it out, thing someone got in the car with wet shoes (I'm in Washington). Then while vacuming I let the seat down and noticed iit was damp in the trunk. So I lifted the spare tire cover and found about 1.5 inches of water. I immediately vacumed it out. Has anyone else seen this before? I saw articles about drain tubes but have yet to locate them. Can anyone help me?

I had this issue with my CTS and is a common problem with those cars. (I checked my LaCrosse this evening and it is designed the same way) There are four tubes, one in each corner of the sunroof. Take compressed air to the ends (or something that you can use to "feed" through the tubes...like a plumbers snake) to get rid of the debris. The tubes are not thick and can get clogged up. (well, at least with the CTS...our LaCrosse seems to have thicker tubing) With my CTS, I also had a third brake light leak PLUS "failed" moonroof seals...I'm pretty sure that wouldn't be the case for you as we do not even have a third brake light outside the vehicle. I HATE to see this happen to the LaCrosse too but seems evident as the design is similar to the CTS. Good luck!

You really should get your car inside somewhere so that things will dry out properly. If you had standing water than the trunk and carpet pad are soaked and need to be fully dried. I would take it in to the dealer and let them check and make certain that the drain tubes to the moon roof are clear and also let them check to make certain that water has not been absorbed in more areas of the carpet than you think.
If the carpet is not fully dry than it might be a good idea to let them keep the car and get the carpet dry.

What a reply and what a way for Buick to screw consumers. Used to be my favorite car.
