MASERATI EMMISSIONS RECALL BULLETIN
PERFORM THE PROCEDURE OUTLINED IN THIS TECHNICAL BULLETIN ON ALL
AFFECTED NEW VEHICLES BEFORE CUSTOMER DELIVERY OR FOR VEHICLES
ALREADY SOLD AND DELIVERED THE NEXT TIME THE VEHICLE 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 or emissions-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.
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.
Furthermore, dealers are prohibited from selling or leasing the motor vehicle or
item of replacement equipment, unless and until the open recall has been
completed BEFORE delivery. This also pertains to items of replacement
equipment. In addition, you may not sell a vehicle with an open recall as part of
the Certified Pre-Owned program.
Finally, MNA dealers should not sell or use parts that have been recalled by
MNA. Please follow the specific instructions provided by MNA for the return or
disposition of any parts.

IMPORTANT EMISSIONS RECALL
February 1, 2019

Maserati VERR#: 373

Dear Maserati Dealer:
This notice is sent to you in accordance with the requirements of the U.S.
Environmental Protection Agency’s (EPA) Voluntary Emission Recall procedures.
Maserati S.p.A. and Maserati North America, Inc., (“MNA”) have decided that a defect
that relates to motor vehicle emissions exists in MYs 2011-2018 Maserati GranCabrio,
GranTurismo/GranTurismo Convertible and Quattroporte vehicles, equipped with the
4.2L and 4.7L gasoline engines.
The suspect vehicles are included in a voluntary emissions recall and a service
campaign related to an engine software defect. Upon start-up of the vehicle, the engine
software does not properly complete the secondary air monitor, resulting in a low
IUMPR ratio. The low IUMPR ratio does not meet the OBD II regulatory requirements.
The remedy for the affected vehicles involves uploading new ECM (engine control
module) operating software into the vehicle. The remedy procedure will be performed
free of charge to the vehicle owner. Please refer to Maserati Recall Bulletin 373MAS001736 for information and VIN specific details for the models affected by this
Recall Campaign. Please refer to Maserati Technical Bulletin 374-MAS001737 for
additional vehicles that are covered under the Service Campaign.
MNA has assigned this campaign an internal Maserati number of 373. We will of course
reimburse you for the labor necessary to carry out this recall campaign. Obviously, if
you have any of the affected vehicles in your stock, you must not sell them until you
have performed the necessary repairs on the vehicle. If you have already sold any of
the vehicles with the indicated VIN in the enclosed instructions and have not yet sent in
the new owner information to MNA, please do so at once so we may notify these
owners.

IMPORTANT EMISSIONS RECALL
NOTE: Additional Information for California Residents/Dealers: The state of
California requires the completion of emission recall repairs prior to vehicle registration
renewal. Failure to complete recalls also may cause the vehicle or engine to fail a
vehicle inspection or smog check test when these tests are required under California
state law. State of California regulations require manufacturer’s dealers to provide the
Department of Motor Vehicles with a record of all vehicles that have not had the recall
service performed.
Once the recall has been performed please fill out the form and provide it to the
customer.
Thank you for your cooperation.
Sincerely,
Maserati Vehicle Safety and Regulatory Compliance

Q&A
Q19. What is the difference between a recall and a service campaign?
A.
A recall requires that all owners be notified directly by mail to have their
vehicle repaired. A service campaign does not require that an owner be
notified by mail (except in Canada, which requires all owners be notified of
a defect). Under a service campaign, the vehicle is repaired when an owner
brings their vehicle into a registered dealer for routine maintenance.
Vehicles are repaired free of charge under both a recall or a service
campaign.
Q20. Why am I being notified for a service campaign in Canada?
A.
All vehicle owners in Canada are required by law to be notified of a defect,
regardless of whether the vehicle is subject to a recall or a service
campaign.
