Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 1 recall campaign for the 2022 Prius Prime over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.

Remedy: Dealers will update the ECU software, free of charge. Owner notification letters were mailed November 18, 2021. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 21TB07/21TA07.
Carmakers sent NHTSA 125 service bulletins and notices that cover the 2022 Prius Prime, the latest on Jan 30, 2026. They tell dealers how to fix known issues.
The parts they mention most: electrical system (37), unknown or other (33), structure (27), equipment (24), engine (6).
NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
