NOTE: Before starting this procedure, you MUST read these instructions carefully and completely.
MASERATI SAFETY RECALL BULLETIN
PERFORM THE PROCEDURE OUTLINED IN THIS TECHNICAL BULLETIN ON ALL AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE NEXT TIME THE CAR IS IN THE SHOP FOR MAINTENANCE OR REPAIRS.
Maserati dealers must ensure recalls are completed after having been notified by Maserati North America, Inc. (MNA) that a safety-related defect or noncompliance exists in any motor vehicle or item of replacement equipment in the dealer’s possession at the time of notification. In MNA's case, this notification would typically be made by the issuance of a recall notification in the form of a Technical Bulletin.
Under the National Traffic and Motor Vehicle Safety Act of 1966, as amended (or in the case of Canadian vehicles, Motor Vehicle Safety Act S.C. 1993, as amended), if a recall campaign is announced by MNA, dealers must ensure that all recalls on new vehicles and new items of replacement equipment are completed BEFORE delivery to the consumer. This means that dealers may not legally deliver new motor vehicles or new items of replacement equipment to consumers with an open recall.
The Safety Act also prohibits dealers from selling or leasing the motor vehicle or item of replacement equipment, unless and until the open recall has been completed BEFORE delivery.
Under the terms of the Certified Pre-Owned (CPO) program, CPO vehicles with an open recall may not be sold or delivered to the consumer.
Finally, MNA dealers should not sell or use parts that have been recalled by MNA. Please follow the specific instructions provided by MNA on the return or disposition of the parts.
Description of Vehicle Safety Recall 359
Maserati S.p.A. and MNA have determined that the above described vehicles were manufactured with a low pressure fuel pump resistor that could potentially fail when the operative current reaches the maximum allowed by the resistor; in that case the resistor failure comes as a result of cycle time and temperature fatigue. If the resistor fails, the low pressure pump will stop working due to an open circuit (resistor failure) and without the fuel pump working, the engine will lose power and eventually stall.
Illustration of the Low Pressure Fuel Pump Resistor Harness
This repair procedure will be performed free of charge to the customer.
NOTE: Be sure to have the customer supply the radio security code because the battery will be disconnected from the vehicle.
Which Vehicles Are Affected
Please refer to the VIN List for the affected vehicles in the U.S. and Canada at the end of the bulletin and in ModisCS+.
