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.

THE C230 MERCEDES BENZ 2002 STARTED LURCHING WHEN COMING TO A STOP. UPON BRINGING THE VEHICLE TO THE DEALER THEY DID A GLYCOL TEST ON THE AUTOMATIC TRANSMISSION FLUID TO FIND GLYCOL IN THE TRANSMISSION. THE CAUSE WAS DUE TO A LEAK IN THE RADIATOR TO THE TRANSMISSION OIL COOLER. REPAIRS CURRENTLY INCLUDED A NEW RADIATOR, TRANSMISSION FLUSH, AND A NEW TRANSMISSION MODULE FOR ABOUT $2100, IF THAT DIDN'T WORK THEN A TORQUE CONVERTER FOR ANOTHER $2700. *AK
