Body problems of the 1996 Infiniti I30

This is my second Infiniti I30 which is the exact same vehicle as the Nissan maxima. I currently own a 1996 and have owned a 1997 prior and both had rust in the middle of the lower radiator core support. Over the weekend I looked at a 2000 Infiniti I30 for a family member considering purchase and noticed the same problem. After 3 different cars all of different model years I did extensive research and have discovered all over the internet that this is a major problem effecting every Nissan maxima and Infiniti I30 from the years 1995-2000 regardless of climate or region. The problem has been brought forth in more of a "venting" format and many people did not think to contact the manufacturer directly. This lower radiator support has a lower engine mount brace that screws in, and once it rusts completely, will allow the engine of the vehicle to potentially drop out from beneath and cause a major automotive collision or even fatality. I have been quoted $1200 to rectify the problem, however I do not think I am responsible or should have to pay for a manufacturers defect. Something needs to be done before lives are lost!!!!.
