Why would they spend thousands of dollars importing fuel blends from around the world when they can just ship a couple test cars to certain locations? I also remember some statements that the suspension was actually tuned by region, so our FR-S probably has a different setup than the GT-86, not a huge difference but there's different parts in there.

Five bucks says the engineers shrug it off, it's only a noise after all, the PR team probably forced a fix to retain "legendary reliability".

You may be right, or they didn't test the cars for more than 2-300 miles. Some people weren't getting the chirp until they got closer to 1000 miles.
