KNOWN ISSUE FOR QUITE SOME TIME. MOST, IF NOT ALL CHINESE MADE FUEL PUMPS ON 2009 YAMAHA ZUMA 125'S HAVE FAILED OR WILL FAIL. YAMAHA, SO FAR, REFUSES TO ACKNOWLEDGE THAT THEY HAVE A PROBLEM, AND REFUSE TO FIX THE ISSUE. OR EVEN REPLACE THE PART. *TT
ZUMA 125 STALLED AT A RED LIGHT IN A LEFT TURN LANE WITH THREE LANES ON EITHER SIDE OF ME, PUTTING ME IN A DANGEROUS POSITION. AT THE TIME I HAD ALTERNATE TRANSPORTATION AND DID NOT TRY TO RIDE IT AGAIN TILL THE FALL. ALL THROUGH WINTER AND SPRING I WENT WITHOUT PROBLEMS, BUT AGAIN THIS MAY IT STARTED TO ACT UP. IT WOULD NOT START IF PARKED IN THE SUN, AND WOULD OFTEN STALL IF IDLING AT A LIGHT, AFTER WHICH IT WOULD NOT START (OFTEN LEAVING ME IN THE MIDDLE OF TRAFFIC). I TOOK IT TO A LOCAL REPAIR SHOP BUT THEY COULD NOT RECREATE THIS PROBLEM …

The 2021 Yamaha Zuma 125 is a fuel injected motorcycle/scooter which can achieve 65 miles per hour and boasts a passenger/load capacity of over 500 lbs. During routine maintenance I found cracks in the front seat support structure, where the seat support is welded to the frame. These cracks are on both sides of the front seat support and are a result of metal fatigue. The steel seat support structures are thin, 16 gauge steel and not well designed to support even a 200lbs passenger. This seat support structure can break without warning caus…

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.

WHEN IT IS HOT, MY YAMAHA ZUMA 125 WILL STALL AT A TRAFFIC LIGHT AND WILL NOT RESTART. WAITING AND TRYING AGAIN SEEMS TO BE THE ONLY SOLUTION AVAILABLE. THE WAIT TIME IS UNPREDICTABLE, 15 MINUTES TO 2 HOURS. SUSPECTING IT IS RELATED TO HEAT I TRY TO WAIT IN SHADE. THE PROBLEM FIRST MANIFESTED MORE THAN A YEAR AGO, AND IS HAPPENING AGAIN WITH INCREASING FREQUENCY. THIS SUMMER IS HOTTER THAN LAST. I HAVE NOTICED RECENTLY THE USUAL HUM W/CLICKING SOUND THAT HAPPENS WHEN THE KEY IS SWITCHED ON IS NOT HAPPENING WHEN THERE IS A PROBLEM. I BELI…
WE BOUGHT THIS BRAND NEW IN 09'. I RODE THIS ONLY AROUND THE NEIGHBORHOOD BECAUSE OUR FAMILY MEMBERS LIVE CLOSE. WE THOUGHT WE HAD A BATTERY PROBLEM AT FIRST AND REPLACED IT IN 2010. THEN WE WENT ON A TRIP SO I WASN'T ABLE TO RIDE IT MUCH FOR THE SEASON. WE TRIED TO RUN IT IN 2011 AND IT RAN FOR A MINUTE (IN THE DRIVEWAY) AND THEN IT STOPPED AND WOULD NOT START AT ALL. WE TESTED THE NEW BATTERY AND IT WAS NOT THE PROBLEM. SO I COULDN'T RIDE IT AT ALL LAST YEAR. THIS YEAR WE BOUGHT ANOTHER BATTERY AND STILL NOT FIRING. THE ONE THING WE NOTIC…
