How serious. Out of all 19 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

Newest year first. Red = worse than average, gray = about average, too new (2023+: a partial score, marked “partial”) or too few complaints to score. #1, #2… = that year's YouTube rank among the 24 Toyota Prius years with enough videos (#1 = the year owners and reviewers talk about most positively). It is not a reliability rank.
