Honda Odyssey motor mount problem

I just had my 2005 Odyssey with 68,000 miles diagnosed with 2 broken motor mounts. The dealer said they cost $500 each plus labor. The dealer stated it is a common problem with that year Odyssey. Luckily my extended warranty is covering the cost of the repair, but Honda should clearly recall the 2005 Odyssey for bad motor mounts. I have never had a problem with broken motor mounts on other Hondas or Toyotas I have owned, all with more miles.
