I own a 2011 3 hatchback, bought new in 2010. Besides wear items, I think I’ve replaced one belt and one hose. It’s only on its third battery and 2nd/3rd lightbulbs all around. Absolutely the most reliable car I’ve ever owned, whether I measure by problems/mile, problems/year, or dollars/year.
I also have a Miata (ND - 4th gen) that gets driven less than 3K miles/year. No problems there other than Mazda’s buggy CarPlay (and insane choice to disable the touchscreen when in motion).
