Just joined the forum after searching for the water in the trunk problem. My first Lexus 400 (1991) had a major trunk leak and filled up with enough water enough to have fish in the wheel well...dealer had it for a month doing all kinds of things supposedly fixing the problem...and still had the problem. Took it in again and they replaced the trunk lid gasket and it solved the problem. Bought another LS400 (2000) and I now have another trunk with water in it after a few years...not what you would expect from a $60K car. Going back to the dealer one more time for the same bad gasket design.
