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.

I BROUGHT MY EXTENDED 2002 TRAILBLAZER IN TO THE DEALER FOR A RECALL ON THE REAR DOORS, A SEAL FOR THE BOTTOM. I THINK IT WAS FOR THE DOOR LATCH RUSTING OUT AND FLYING OPEN WHILE YOUR DRIVING. I TOLD THEM TO CHECK THE ABS BECAUSE THE WARNING LIGHT WAS ON. THEY SUPPOSEDLY CHECKED IT OUT AND TOLD ME THAT THE FRONT DRIVERS SIDE HUB WAS VERY WOBBLY AND IT CAUSED THE SENSOR TO GO BAD. ME BEING A MECHANIC ALSO, DECIDED TO TAKE IT TO MY TRUSTED GARAGE AND TOLD THEM TO REPLACE THE HUB. MY VEHICLE ONLY HAS 45000 MILES ON IT AND I DIDN'T THINK THAT THIS …

CHECK ENGINE LIGHT CAME ON MY 2002 CHEVROLET TRAILBLAZER (86,000 MILES). TEAM CHEVROLET ANALYZED AND ADVISED THE GAS TANK IS CRACKED. THIS SAME PROBLEM OCCURRED AT 12,000 MILES BUT WAS REPAIRED FOR FREE AS VEHICLE WAS UNDER WARRANTY AND THERE WAS AN ALERT ISSUED FOR THIS PROBLEM. HOWEVER, THE ALERT "POLICY" RAN OUT AT 70,000 MILES SO THE DEALERSHIP, NOR GM WILL COVER THE ESTIMATED EXPENSES OF $850. I PROTESTED THAT THIS WAS A KNOWN AND REPEATED PROBLEM AND A FIRE/SAFETY ISSUE BUT THEY ARE NOT WILLING TO ASSIST IN ANY WAY. *JB
