Complaint evidence
Examples provide context, not a representative sample or a verified diagnosis.
(1) PROBLEM WITH BOTH ENGINE CRANKSHAFT PULLEY AND DRIVE SHAFT. THE ALLEGATION IS THAT THE ENGINE CRANKSHAFT PULLEY FAILURE CAUSES LOSS OF POWER STEERING ASSIST AND ACCELERATION WHICH MAY INCREASE THE RISK OF AN ACCIDENT(1 FAILURE). (2) REPEATED PROBLEMS WITH FRONT BRAKE PADS DUE TO PROBLEM IDENTIFIED BY SERVICE TECHNICIAN CONCERNING BOTH FRONT BRAKE HOSES(3-4 FAILURES). (3) CRACKED CATALYST CONVERTERS PROBLEM THAT IS PROBLEMATIC WITH ML AND REQUIRES A $3-4000 REPAIR(1 FAILURE). *NM
THE FUEL PUMP FAILED LAST YEAR, WHICH I UNDERSTAND IS COMMON IN THIS VEHICLE. THE TWO MAJOR PROBLEMS NOW ARE THAT THE CAR MAKES A LOUD "CLUNK" WHEN MAKING CONTINUOUS TURNS (E.G., RAMPS) EVEN AT LOW SPEED, AND THE STEERING WHEEL IS MAKING ODD SOUNDS. ALSO THE HEATER MAKES THE FRONT CONSOLE TOO HOT TO TOUCH ON THE RIGHT SIDE.*AK

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.
