NHTSA gives the 2012 Toyota Prius an overall crash rating of 5 out of 5 stars. Crash ratings measure occupant protection in a collision; they do not measure reliability, which is what the complaint data above reflects.
All figures come from the U.S. National Highway Traffic Safety Administration (NHTSA) public APIs: the Office of Defects Investigation complaint database, the recalls database, and NCAP safety ratings, retrieved September 7, 2026.
Complaints are self-reported by consumers and are not verified by NHTSA or by this site. A single complaint may cite multiple vehicle systems, so system mentions can sum to more than the complaint total. Complaint volume is influenced by fleet size, media attention, and recall notices, and is not by itself a measure of defect rates.
