Emerging complaint spikes
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.
2018: 0 complaints · 2019: 1 complaints
