ON CERTAIN RECREATIONAL VEHICLES BUILT ON GM GMT610 RV CHASSIS, DUE TO A CHANGE IN THE FUEL SYSTEM OF THESE CHASSIS, INCREASED PRESSURE RESULTS IN THE FUEL RETURN LINE. THE FUEL RETURN LINE IS USED TO PROVIDE A FUEL TAP FOR GENERATORS AND AUXILIARY ENGINES.
OPERATING THE GENERATOR WHILE THE VEHICLE ENGINE IS RUNNING WILL STALL THE GENERATOR DUE TO OVERFUELING. STARTING, PRIMING OR OPERATING THE GENERATOR WITH THE VEHICLE ENGINE RUNNING COULD RESULT IN FUEL OVERFLOWING THE CARBURETOR, FLOODING THE GENERATOR ENGINE AND SPILLING FUEL INTO THE GENERATOR COMPARTMENT AND ON THE GROUND.
GM/ONAN ADVISED JAYCO TO STOP DELIVERY OF THESE UNITS UNTIL A SOLUTION TO THE PROBLEM IS DEVELOPED. THE MANUFACTURER HAS NOT YET PROVIDED AN OWNER NOTIFICATION SCHEDULE FOR THIS CAMPAIGN. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT JAYCO AT 1-574-825-0653.
CUSTOMERS CAN ALSO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S AUTO SAFETY HOTLINE AT 1-888-DASH-2-DOT (1-888-327-4236).
