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.

I OWN A 2002 YAMAHA ROAD STAR WARRIOR. THE FUEL "QUICK DISCONNECTS" ARE IN MY OPINION, DESIGNED & ENGINEERED VERY POORLY. THEY VIBRATE OFF THE SEAT. THEY HAVE NEVER LEAKED FUEL, THE LOCKING TAB MAKES IT STAY LOCKED SO IT WON'T LEAK. HOWEVER, WHEN IT IS AGAINST THE LOCKING TAB, IT MOVES OFF ITS SEAT ABOUT 3/16" AND RESULTS IN NO FUEL FLOW FROM THE UPPER TANK TO THE LOWER TANK WHERE THE ELECTRIC FUEL PUMP IS. THAT RESULTS IN A "STALL" SITUATION. I WAS SITTING AT A RED LIGHT WAITING FOR IT TO TURN GREEN, I STARTED OUT AS I ALWAYS DO. I WAS AT 8 M…

I HAVE A 2002 YAMAHA ROAD STAR WARRIOR. I BOUGHT THE MOTORCYCLE NEW FROM THE DEALER AS A 2002 LEFTOVER IN MAY OF 2003. A FEW WEEKS AFTER I BOUGHT THE MOTORCYCLE, I WAS RIDING DOWN THE ROAD AND THE BIKE STARTED TO SLOW DOWN ON ITS OWN. BEING A FEW MILES FROM A FRIEND'S HOUSE, I DECIDED IT WOULD BE SAFER TO STOP THERE, SO I CONTINUED ON TO HIS HOUSE. WHEN I PULLED IN THE DRIVEWAY, I NOTICED MY REAR BRAKE ROTOR WAS GLOWING RED AND THE WHOLE CALIPER WAS SMOKING AND HOT. THE BRAKE LINE MELTED AND LEAKED FLUID ON THE HOT CALIPER AND THEN CAUGHT …
