Front Seat Power Adjust problems of the 2006 Honda Pilot

Drivers power seat adjuster assembly l reclining 81630-s3v-a30 failed catastrophically at front left corner bracket cracked due to metal fatigue leaving seat partially unsecured to the vehicle. This is not a wear point the metal support bracket simply sheared off. Vehicle was not involved in any accident or off road activities that might have caused or stressed vehicle or its components in any way. As a result seat and seat back are unsecured falling flipping backward during acceleration and certainly would not be safe during an accident especially a rear collision would probably causing serious bodily injury and possibly death to the occupant driver and effect the integrity of the seat belt and air bag systems. If this part was to fail while driving it might startle driver and cause and accident. Honda was immediately contacted and refused repair or replace at their expense or even participate / contribute in any amount toward the repair or replacement. They denied there is a known problem despite numerous similar complaints on this site and the Honda and accord forums. I believe this same part is common in Pilot, accura mdx and odyssey Mini vans model years of 2004, 2005, 2006, 2007 and 2008 and possibly others.
