ive had problems with mine, water under the drivers seat.
turned out that pretty much all the drains were clogged, and i mean clogged ashell. after cleaning them out, front and back, no more problems.
so just make sure you look at them now that you know about the possible problems. there are 2 drains on both sides of the battery, and 2 are in the back when you put your car in service position.
heres where they are located in the diagrams
