 I was surprised to see the review by leon written 1/15/2008. I have just experienced the exact same failure on my Hyundais' front passenger side wheel collapsing. My local dealership also refused to repair my sub-frame rusting under warranty. This seems to be a wide-spread problem. And I too believe this should be repaired under their 10 yr bumper-bumper warranty. The Sonata is a fun, sleek and enjoyable car, but Hyundai often waffles on their warranty coverage; which was one of the major selling points that impacted my purchasing decision. .
