Agreed I don't think the dealer will pay for the cost of this. I know
that the 04 TSXs had this problem but Acura paid for the replacement
as there was a high number of people who were getting this problem.
Seals go bad and unfortunately the only true way to repair this is by
replacing the headlamp assembly. Make sure that you don't let a puddle
of water form on the inside of the lens or you can kiss you headlights
goodbye, and those Xeon bulbs are expensive to replace.

And as tegger says, it requires the removal of the front bumper so you
need to be mechanically inclined to do this. It isn't an impossible
job to do but you need to know what you are doing.
