Recall history

2 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.

07V219000 · Fuel System, Gasoline:Delivery:Fuel Pump

Reported: 2007-05-24 (May 24, 2007)

ON CERTAIN MOTORCYCLES, A LEAK AT THE FUEL PUMP SEAL MAY ALLOW FUEL LEAKAGE.

Consequence: FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.

Remedy: DEALERS WILL REPLACE THE FUEL PUMP SEAL FREE OF CHARGE. THE RECALL BEGAN ON JUNE 18, 2007. OWNERS MAY CONTACT YAMAHA AT 1-800-962-7926.

NHTSA campaign record ↗

08V180000 · Fuel System, Gasoline:Delivery:Fuel Pump

Reported: 2008-04-23 (April 23, 2008)

YAMAHA IS RECALLING 9,600 MY 2006-2007 CP250 AND MY 2005-2007 YP400 MOTORCYCLES. THE ENGINE COULD STALL AND BE DIFFICULT TO RESTART BECAUSE THE WIRE TERMINALS IN THE FUEL PUMP WIRE COUPLER HAVE CORRODED. WATER CAN ENTER FROM THE MAIN WIRE HARNESS END AND RUN THROUGH THE HARNESS TO THE FUEL PUMP COUPLER.

Consequence: IF THE WATER REMAINS IN THE COUPLER FOR AN EXTENDED PERIOD OF TIME, THE TERMINALS CAN BECOME CORRODED, WHICH CAN PREVENT THE FUEL PUMP FROM OPERATING PROPERLY. IF THIS CORROSION AFFECTS FUEL PUMP OPERATION WHILE THE SCOOTER IS BEING RIDDEN, THERE COULD BE A CRASH RESULTING IN INJURY OR DEATH.

Remedy: DEALERS WILL INSTALL A SUB-HARNESS WHICH IS DESIGNED TO ALLOW ANY WATER BETWEEN THE WIRE HARNESS AND THE FUEL PUMP TO DRAIN OUT BEFORE IT REACHES THE FUEL PUMP. THE DEALER WILL ALSO INSPECT THE CONNECTORS. IF EITHER THE MAIN WIRE HARNESS CONNECTOR OR THE FUEL PUMP CONNECTORS IS ALREADY CORRODED, THE CORRESPONDING ASSEMBLY(IES) WILL ALSO BE REPLACED. THE RECALL BEGAN ON MAY 9, 2008. OWNERS MAY CONTACT YAMAHA AT 1-800-962-7926.

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.
