Apparently. The 1st thing I experienced in '06 was the leak. The dealer replaced the seal. It leaked again and the dealer claimed it was due to vent tube contamination.
A knowledgeable friend thoroughly explained that the whine indicates damage so after the third leak began, I insisted that the carrier be replaced. The dealer complied.
