2008 YAMAHA YP400 Complaints

THIS IS A 400CC MOTOR SCOOTER BEING RIDDEN DURING AN 85 DEGREE DAY. THE VEHICLE ENGINE STALLED AFTER ENTERING A BUSY INTERSECTION AND COULD NOT BE RESTARTED. AFTER PUSHING THE VEHICLE OUT OF THE INTERSECTION, ATTEMPTS TO RESTART FOR OVER AN HOUR FAILED AND THE VEHICLE WAS TRAILERED HOME. THIS SCENARIO WAS ( HOT TEMPERATURE STALL AND FAILED RESTART) WAS REPEATED AT MY RESIDENCE ON THREE DIFFERENT OCCASIONS. THE VEHICLE WAS TAKEN TO THE YAMAHA DEALERSHIP, DIAGNOSED WITH A FUEL PUMP ASSEMBLY FAILURE, AND CONFIRMED REPAIR UPON PUMP REPLACEMENT. IT CAN BE CALCULATED FOR APPROXIMATE PUMP LIFE TO BE 80 TO 120 HOURS OF OPERATION (AVERAGE 20 TO 30 MPH) FOR THE LIMITED 2360 MILES ACCUMULATED. THIS IS NOT AN ACCEPTABLE COMPONENT LIFE FOR A FUEL INJECTION VEHICLE AND INDICATIVE OF A MANUFACTURING QUALITY PROBLEM THAT COULD RESULT IN POTENTIALLY FATAL ACCIDENT SHOULD PUMP FAILURE OCCUR IN A BUSY INTERSECTION. I INQUIRED ABOUT WHETHER THIS PUMP FAILURE COULD BE CUSTOMER INDUCED AND WAS TOLD THEY WERE UNAWARE THAT IT WAS POSSIBLE TO CAUSE THIS IN-FUEL TANK PUMP TO BE ABUSED BY CUSTOMERS.
