I am going to be driving in the US for a month or so this summer. I am wondering if, should anything go wrong, it is possible to use Versa or fake-Versa parts to fix a possible Micra problem?

Not expecting any issues as I have only 15,000 kms on my Micra and most of the kinks worked out with a fabulous dealership here in Victoria, but it would be nice to know.....
