The article notes that the most recent recall was a physical one, not a software update, and implies that that was unusual. I wonder if you exclude "recalls" resolved by software updates, for all cars, where it would rank then?
Not sure where it would rank at '5 recalls' instead of '6 recalls' but suboptimal nevertheless.
(I think the article noted that because the immediately previous one *was* a software update ... but it appears that's the only one that was)
