MY 2009 SUBARU IMPREZA WRX, WHICH I USE AS A DAILY DRIVER, HAD A MAJOR ENGINE BREAKDOWN AT ABOUT 9000 MILES CONSISTING OF A LOUD KNOCKING SOUND AND EXTREME ENGINE VIBRATION.

SCHEDULED MAINTENANCE HAD BEEN DONE PRIOR TO THE FAILURE (OIL CHANGES).

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
