Yup, I believe for all affected R50s it's always only the passenger side inflator.
As the population and area of the whole country doesn't even get close to rival that of the smallest state in the US, most car brands are usually served by one dealer with branches in other provinces. Interestingly enough, Nissan at some point had two different dealers but one merged and went on to sell something else so we're back to just one and I'm screwed.
Locally they are insisting all checks on the VIN come up as being safe. The Nissan US rep told me to sit tight and they would take care of talking to whatever dealer is rejecting the replacement, which leads me to think they checked the VIN. If there is an internal database at Nissan with more accurate data than what the NHTSA or Nissan's public website output, then I'd love to have at least an screenshot of that, alas, I don't have anything.
I'll give Nissan US another week or so and the next step after that is going to the dealer personally to get some evidence of where they claim my VIN is showing up as safe.
