Solid line: filed complaints. Dashed amber lines: recall announcement dates for this vehicle selection; markers include all recall components. The latest month is partial. Temporal proximity does not establish causation.
Monthly counts, recall campaigns and complaint examples
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
