just a suggestion but it might be a good idea to document the VX maintance and symptoms. Also people that have experienced engine failure with this particular engine regardles of vehicle model (I.E. VX,TRooper) should keep in touch with one another. This way if there is reasonable doubt and proof (ISUZU bullletin, Logs) then the group can hire a lawyer and go after Isuzu as a group instead of trying to fight the Giant one by one. It also might help that Isuzu Customer service relation know that this group exists so the next VX or Trooper person might have a more courteous dealing with Corporate. I have found that information present and organized will get your further than trying to handle the person by word of mouth.

The net is large so groups such as this, planet Isuzu etc... can offer more voice than the average Joe. (Why doesn't the Joe ever get picked? )

ISUZU owners of the world UNITE!
