What this means for owners
- Check open recalls first. A manufacturer recall covering this component means the repair is free at a dealer — the 2005 Toyota Prius recall list is on the model year page.
- Reported, not proven. These are unverified owner complaints. Volume shows a pattern worth checking with a dealer or mechanic, not a confirmed defect in every vehicle.
- Mileage is a guide, not a schedule. Half of the reported failures happened before the median mileage and half after — maintenance history and driving conditions move that point a lot.
- Compare within the model line. If this component also fails early on adjacent model years, the pattern is stronger than a single-year spike.
