How is water getting inside my 2009 Subaru Outback?

Twice now in heavy rain our '09 Outback has taken in a significant amount of water, mainly collecting in rear passenger seat foot-wells. Any idea how it’s getting in? All windows were closed.

Short of a broken or degraded window seal, check the door rubbers for signs of damage. Sometimes, it’s as simple as a small twig or even a thick blade of grass sticking to the rubber seals that will allow water in. However, there’s a more likely answer. If it was the front-seat foot-wells that were wet, I’d be blaming the air-conditioning vent that is supposed to drain the water - that builds up in the system - to under the car, but can sometimes lock or clog and run the water into the car.

So let me ask you a question: Does your car have a sunroof? If the answer is yes, that’s where I’d be looking. The sunroof, being set into the roof panel, naturally collects water when it rains. So, there are tubes that run from the sunroof, down the rear pillars of the car and vent to the outside just in front of the rear wheels. If these drain tubes block up, the water will run down the outside of them and into the rear foot-wells. Cleaning out the tubes will usually fix the problem.
