Bought a new Accord LX. Made in Japan. Top quality, right?
Wrong. Drove the car for the first time in the rain yesterday. Rear right-side passenger seat was soaked... I mean sodden! No moisture in the trunk, and windows were closed. So water must be coming up from below.

Anyone have any idea where/how the water might be getting in?

What a disappointment! Car has only 1,000 miles.
