Here is a simple solution. Go to your local Isuzu dealer. Hopefully there is one nearby. Give the sevice tech guy your
VIN # and ask him to check the service records for you. If any work has been done by an Isuzu Dealer, and it probably was because it was under warrenty, it will show up.

Hope that helps.
