I have a cousin who just bought a 2006 Tucson (approx 6000 kms). The rear seats fold down flat. Both seat belt buckles in the rear have gotten caught somewhere during lowering and raising of the seats. Now both buckles are broken (plastic housing is busted off). Hyundai says that they wil not cover this under warranty. Has this ever happened to anyone else? If so, did this get covered by Hyundai? Thanks
