Sounds fishy to me. Like others have pointed out, the driveshaft doesn't get that hot and is a very unlikely candidate to melt the dust boot for the shift assembly. Ask to look at it for yourself and take a photo.
Regardless of what happened, if you or another shop installed the short shifter and did not secure the dust boot properly, then it and whatever it damaged will not be covered by the Nissan warranty.
