These are unverified consumer reports and manufacturer recalls filed with the National Highway Traffic Safety Administration — not validated defect rates, and not adjusted for how many units were produced or sold. High-volume and older vehicles naturally accumulate more complaints. Use this as one research signal, not a verdict on any individual vehicle, and not financial, safety, or purchasing advice.
