The 2006 Yamaha Yp400 has 2 NHTSA recall campaigns affecting an estimated 23,558 vehicles. Recall repairs are always free at any authorized dealer. Owners have filed 5 complaints with NHTSA, most often about the engine and engine cooling. Last updated July 5, 2026.
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…
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.
