2010 TOYOTA PRIUS

What owners reported to NHTSA, ranked by how often and how seriously.

This is complaint data, not a random sample.

It only includes owners who chose to file a federal complaint, so it over-represents dramatic and safety-related problems and under-represents minor issues an owner just had fixed without reporting. Read this as what NHTSA complainants report most, not as this vehicle's true failure rate. Full methodology.
