The P55 had problems when it was first released. The Foxconn sockets would burn up if you overclocked/overvolted your cpu. This was fixed quickly by pulling all the boards with Foxconn sockets off the shelf and replacing them with other branded sockets. Not sure if H55 sockets were affected.
The newest recall is the P67/H67. Nothing wrong with the chipset, just that the Sata ports can degrade over time. They have been replaced now by the P67/H67 B3 revision.
Intel QC has not been good lately.
