Toyota Prius — the 16 years we've written up
2010–2024, side by side: what goes wrong on each, what the fix costs, and what they typically ask. 11 of the 16 carry a high-severity issue.
What this page is
These are the 16 Toyota Prius model years Kestrel has done the homework on — not every year Toyota built one. A year that isn't listed here isn't a year we're warning you off; it's one we haven't written up yet. Ranking a whole model run would mean telling you about years we've never looked at.
