Unless you purchased "seal and gasket" insurance, then no the seals are not covered. The caulking on the roof seams, which the dealer is probably talking about, is a normal maintenance item and is also not covered. You should check and re-caulk where necessary at least once a year.
I, and many others on the forum, covered all of my roof seams with
Eternabond tape which you can put on right over the existing caulk after cleaning it. It makes the seam impossible to leak and should last for many years. Mine has been on since 2005 or so and still looks like the day it was installed. No more worries about leaks! :B
