TODAY I WAS DRIVING MOSTLY ON HIGHWAYS THEN I GOT OFF AND THE ABS LIGHT CAME ON. THEN I SAW SMOKE SO I STOPPED AND LOOKED AND THERE WAS A FIRE IN THE BRAKES AREA ON MY DRIVER SIDE FRONT TIRE. THERE WAS FLAMES SHOOTING UP 12 INCHES. AFTER DISTINGUISHING THE FIRE AND LETTING THE WHEEL COOL OFF I TOOK THE TIRE OFF TO INSPECT IT AND DISCOVERED THAT THE ABS SENSOR CAUGHT ON FIRE. *TR

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.
