Usually it's not the chips actually desoldering so much as it is thermal cycling causing the solder joints to crack. Most ICs can't really survive being heated to solder melt temperature for an extended period. Either way, it's pretty bad that they didn't do something about it. That's indicative of a pretty serious manufacturing or design flaw.
