2009 Yamaha YW125

MY ZUMA 125 SCOOTER WITH AROUND 800 MILES STALLED WHILE I WAS IDLING IN A FAST FOOD DRIVE-THRU ON A DAY WHEN THE TEMPERATURE WAS OVER 90 F AND WOULD NOT RESTART. I WAS ABLE TO RESTART AFTER LETTING THE SCOOTER COOL DOWN FOR ABOUT 20 MINUTES IN THE SHADE. THIS SAME ISSUE OCCURRED AGAIN ON ANOTHER HOT DAY AROUND 95 F WHILE I WAS AT A STOP LIGHT ON A BUSY ROAD. AFTER PUSHING MY SCOOTER TO A NEARBY GAS STATION I WAS ABLE TO RESTART AFTER COOLING DOWN THE SCOOTER FOR ABOUT 20 MINUTES IN THE SHADE. I AM NOW UNABLE TO START OR KEEP MY SCOOTER RUNNING WHEN IN DIRECT SUNLIGHT ON A HOT DAY AND HAVE HAD NO PROBLEMS ON COOLER DAYS OR IN THE EVENING. I HAVE CALLED LOCAL YAMAHA DEALERS AND THEIR PRIMARY CUSTOMER SERVICE NUMBER ONLY TO BE TOLD THAT THERE ARE NO KNOWN ISSUES. AFTER CHECKING ONLINE FORUMS I HAVE DISCOVERED THAT THERE IS A COMMON ISSUE WITH THE FUEL PUMP, WHICH YAMAHA HAS SINCE REDESIGNED, YET STILL DOES NOT RECOGNIZE AS THE SAFETY ISSUE THAT IT IS. MY FUEL PUMP ISSUE STILL EXISTS AND I AM UNABLE TO RIDE MY SCOOTER DURING THE DAY. THE FUEL PUMPS ARE ALSO CURRENTLY ON BACKORDER DUE TO THE COMMON FAILURES. *TR

THE VEHICLE WILL START UP MOST OF THE TIME AFTER BEING PARKED FOR EXTENDED PERIODS OF TIME, BUT AS THE VEHICLE IS BEING USED REGULARLY DURING THE HOTTEST PART OF THE DAY IT WOULD STALL WHILE AT A LOW SPEED OR IDLE. THE PROBLEM GETS WORSE OVER TIME, AND EVENTUALLY IT WILL STALL WHILE AT FULL THROTTLE AND WILL NOT RESTART AFTER SEVERAL ATTEMPTS. THE VEHICLE HAS STALLED ON ME ONCE WHILE ON A 45MPH STREET AND ONCE ON AN INTERSTATE HIGHWAY IN THE SLOW LANE WHILE AT GREATER THAN 55MPH. ON THE LATER OCCASION I WAS STRANDED ON THE SIDE OF THE HIGHWAY AND HAD TO PUSH THE VEHICLE ALONG THE SIDE OF THE ROAD BACK TO THE DEALERSHIP DURING THE NIGHT AFTER SEVERAL FAILED ATTEMPTS TO START IT UP. I HAVE ALSO HAD THE VEHICLE STALL IN THE MIDDLE OF A BUSY INTERSECTION DURING HEAVY TRAFFIC WHILE TAKING A LEFT HAND TURN. I HAD TO WALK THE VEHICLE TO THE SIDE OF THE ROAD TO PREVENT AN ACCIDENT. I HAVE SINCE TAKEN THE VEHICLE TO THE SERVICE SHOP FOR WARRANTY REPAIR ON MULTIPLE OCCASIONS TO SOLVE THIS PROBLEM. THEY HAVE REPLACED THE FUEL PUMP, THROTTLE BODY, BATTERY, ECU, AS WELL AS REGULAR MAINTENANCE TO TRY TO RESOLVE THIS PROBLEM. THE PROBLEM PERSISTS AS OF THIS COMPLAINT AS THE SERVICE SHOP HAS NOT SUCCESSFULLY REPAIRED THE VEHICLE. I DO NOT HAVE POSSESSION OF THE OLD PARTS THAT WERE REPLACED UNDER WARRANTY. THE VEHICLE IS A 2009 YAMAHA ZUMA 125 SCOOTER WITH APPROXIMATELY 6400MILES. *TR
