YAMAHA Complaints

EXTREME JERKING AND STALLING OF THE ENGINE AT HWY SPEEDS IN A CONGESTED AREA CAUSING EXTREME WORRY ABOUT BEING HIT FROM BEHIND OR BEING TOSSED OFF AND TRASHED ON I-40. DURING THE MECHANICAL INSPECTION IT WAS DISCOVERED THAT THE FUEL PUMP'S PLASTIC HOUSING HAS A FLAW, THERE IS A COLD MOLD LINE IN THE PRESSURE VESSEL. THERE IS A LONG AREA OF THE HOUSING THAT IS VISIBLY FLAWED; AN EXCESSIVELY THIN WALL SECTION THAT IS A RESULT OF A MOLDING PROCESSES INABILITY TO MAINTAIN PROPER MOLD FLOW AT THE PROPER TEMP TO ASSURE A COMPLETELY SOLID PRESSURE VESSEL. THIS FLAW HAS ALLOWED THE FUEL PUMP HOUSING TO RUPTURE CAUSING RAPID CHANGES IN FUEL PRESSURE BEING SUPPLIED TO THE FUEL INJECTORS. THIS UNPREDICTABLE JERKING AND STALLING OF THE ENGINE IS A DANGER TO ALL WHO MAY HAVE THIS UNPREDICTABLE FLAW IN THEIR SYSTEM.

WHILE RIDING HOME FROM WORK, I SHIFTED INTO 3RD GEAR AT ABOUT 30 MILES PER HOUR AND HEARD A GRINDING SOUND. WHEN I SHIFTED INTO FOURTH, IT WENT AWAY. UPON DOWNSHIFTING, WHEN I DOWNSHIFTED INTO THIRD WHEN COMING TO A STOP AT A RED LIGHT, I HEARD THE NOISE AGAIN. WHEN I STARTED AGAIN FROM THE RED LIGHT, IT MADE THE NOISE AGAIN, ONLY IN THIRD GEAR. I LOOKED ONLINE AND SAW MANY OTHERS HAVE HAD THIS SAME PROBLEM. THIS MOTORCYCLE HAS BEEN RIDDEN VERY EASY, AND ONLY HAS 16,190 MILES IN 8 YEARS. THIS SHOULD NOT BE HAPPENING.

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 TO DIAGNOSE IT, SO THEY JUST PREFORMED SOME ROUTINE MAINTENANCE. TOOK IT TO MY LOCAL DEALER FOR A SECOND OPINION, THEY DIAGNOSED THE PROBLEM AS A FUEL PUMP ISSUE. YAMAHA WAS CONTACTED BUT DENIED THE CLAIM BECAUSE OF MILEAGE. AT THIS TIME I HAVE NOT MADE THE REPAIR AS IT DOES NOT SEEM COST EFFECTIVE. A 4 YEAR OLD SCOOTER WITH JUST OVER 10000 MI SHOULD NOT HAVE THIS PROBLEM!

TL* THE CONTACT OWNS A 2006 YAMAHA XVS11VR MOTORCYCLE. THE CONTACT STATED THAT WHILE RIDING AT APPROXIMATELY 65 MPH, THERE WAS AN ABNORMAL NOISE THAT CAME FROM THE REAR OF THE MOTORCYCLE AND THE ENGINE. THE MOTORCYCLE WAS DRIVEN TO THE DEALER. THE TECHNICIAN DIAGNOSED THAT THE REAR DRIVE SHAFT BOLT HAD FRACTURED AND THE ENGINE WAS DAMAGED. AS A RESULT, BOTH THE DRIVE SHAFT AND THE ENGINE NEEDED TO BE REPLACED. THE MOTORCYCLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 8,000.

WHILE RIDING APPROXIMATELY 60MPH IN TRAFFIC, JUST PULLED AHEAD OF SOME VEHICLES, AND THE ENGINE STARTED TO LOSE POWER, SHUDDER, AND THEN IT MADE A LOUD SCREETCHING SOUND, AND LOCKED UP THE REAR TIRE WHEN THE ENGINE DIED. I PULLED IN THE CLUTCH, RELEASING THE REAR TIRE, AND THE ENGINE WAS STILL DEAD. TRIED THE STARTER, NOTHING. DOWNSHIFTED AS THE BIKE COASTED SLOWER INTO 3RD GEAR, AND SLOWLY LET OUT THE CLUTCH, AND IT "BUMP STARTED" THE ENGINE, BUT NOW IT WAS MAKING A MASSIVE TICK TICK TICK TICK TICK NOISE. (MUCH LOUDER THAN THE OTHER MINOR TICK NOISES I'D HEARD, MAINLY WHEN IT WAS COLD, RIGHT AFTER START UP BEFORE.) I VERLY SLOWLY AND AT LOW RPM MADE IT TO WORK, AND THEN SLOWLY AT LOW RPM MADE IT HOME ON THE BIKE, BUT THE ENTIRE TIME, IT IS MAKING A LOUD TICK TICK TICK TICK NOISE. I TRIED A COMMON FIX, OF USING A LONGER SET SCREW, ADJUSTED FINGER TIGHT, TO KEEP THE "AUTOMATIC" CAM CHAIN TENSIONER FROM BACKING OFF, AND MAKING THE LOUD TICK TICK TICK TICK NOISE. THIS SEEMED TO FIX THE BIKE. I RODE TO WORK AGAIN THE NEXT MORNING, AND BAM, JUST ABOUT THE SAME PLACE, ABOUT 65MPH THIS TIME, AFTER PASSING SLOWER TRAFFIC, AND GETTING INTO THE CLEAR, THE BIKE SHUDDERED AND THEN EVEN LOUDER THAN BEFORE, THE ENGINE LOCKED UP, SLIDING THE REAR TIRE. I PULLED IN THE CLUTCH, AND IT RELEASED, AND I WAS NEARLY RUN OVER BY THE TRAFFIC BEHIND ME THAT I'D JUST PASSED. THIS IS NO LONGER JUST AN ISSUE OF NOISE< NOW IT"S PUTTING MY LIFE IN DANGER. LET ME REPEAT: THIS TIMING CHAIN NOISE HAS GONE FROM ANNOYING, TO LIFE THREATENING DUE TO ENGINE SIEZE UP AT SPEED NOW MULTIPLE TIMES. PLEASE FORCE YAMAHA TO STEP UP, REPLACE THIS FAULTY AND LIFE THREATENING DESIGN FLAW IMMEDIATELY.

I STOPPED DURING A MOTORCYCLE RIDE TO TAKE A PICTURE AND TURNED THE IGNITION KEY ON MY MOTORCYCLE TO THE OFF POSITION. WHEN I TURNED THE KEY BACK TO ON NO POWER WAS AVAILABLE. REPEATED ATTEMPTS TO USE THE KEY WERE UNSUCCESSFUL. I KNEW THERE HAD BEEN A RECALL ON SUBSEQUENT YEARS OF THE SAME MODEL MOTORCYCLE FOR THIS PROBLEM. IF THIS WOULD HAVE HAPPENED WHEN I WAS IN MOTION THE ENGINE WOULD HAVE IMMEDIATELY STOPPED AND ALL ELECTRICAL POWER TO THE MOTORCYCLE SYSTEMS WOULD HAVE BEEN LOST AS WELL.

THE SPEEDOMETER IS NOT BRIGHT ENOUGH TO PROVIDE CURRENT SPEED IN DAYLIGHT CONDITIONS AND CREATES AN INABILITY TO KNOW YOUR CURRENT SPEED.

TL* THE CONTACT OWNS A 2006 YAMAHA V STAR 1100. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 50 MPH, AN ABNORMAL GRINDING NOISE EMITTED FROM THE REAR PASSENGER SIDE OF THE VEHICLE. THE CONTACT ALSO NOTICED THAT THE SPEEDOMETER FAILED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC, WHERE IT WAS DIAGNOSED THAT THE DRIVESHAFT NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 23,266.

THE VEHICLE MAKE A PRONOUNCE RATTLING SOUND IN 3RD GEAR. OTHERS HAVE HAD THE THIRD GEAR FAIL AFTER NOTICING THIS RATTLING SOUND.

TL* THE CONTACT OWNS A 2009 YAMAHA XVS95CTYR (NA). WHILE DRIVING AT 65 MPH, THE REAR OF THE MOTORCYCLE WHEEL BEARING LOCKED UP. THE FAILURE RECURRED TWICE. THE MOTORCYCLE WAS TAKEN TO THE DEALER. THE TECHNICIAN INSPECTED THE VEHICLE, BUT WAS UNABLE TO DIAGNOSE THE FAILURE. THE MOTORCYCLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 15,000.
