A single report can name several systems, so these figures overlap and must not be added together — their sum is larger than the report total above.

A further 7,941 complaint records exist for this vehicle where the source stated no model year. They are not counted above and appear on no year page.

These are owner-submitted allegations, not confirmed defects. Counts are record counts in the dataset. No exposure denominator exists, so no failure rate or reliability score can be derived from them.
