GranTurismo –Trunk Lock Cover Check
DATE: March 31, 2026
Certain Maserati vehicles listed in MODISCS+ are involved in a Rapid Update to inspect and
possibly replace the rear trunk lock cover.
VEHICLES INVOLVED: GranTurismo (All versions), Model Years 2025–2026
As part of our internal quality monitoring, we have identified a potential manufacturing
irregularity affecting a limited number of vehicles. The trunk lock mechanism cover on certain
units may not have been installed to our intended specification. Over time, and particularly with
frequent or heavy use, this condition may cause the cover to become partially detached.
It is important to note that this concern has no impact on vehicle safety or trunk functionality.
The trunk continues to operate as designed. The issue is purely cosmetic and does not meet our
expected quality standards.
We remind you that all the Rapid Updates must be performed within the first workshop visit,
regardless of the Mandatory setting set in Modis, as required by Maserati policies.
Also, for vehicles in Stock Dealer / PDI, it is necessary to carry out all action operations before
delivery to the end customer, as required by the White Book and explicitly reported in the Predelivery checklist.
Please read and review this bulletin first before ordering parts and/or starting the procedure.
Contact your Regional AfterSales Manager (RAM) or the Technical Support Helpdesk if you
have any questions.
Thank You for your continued support and cooperation.

1. Always check ModisCS+ to see if the vehicle is involved in this action and if it has not been
previously performed.
2. Before checking the cover, perform 10 (ten) complete opening and closing cycles of the trunk lid.
IMPORTANT: To prevent potential damage, perform all trunk cycling operations using only the
vehicle’s designated open and close buttons. For vehicles equipped with automatic trunk
opening, allow the system to complete the full operation without applying any manual force.
3. After completing the stress cycle, use a 5 mm feeler gauge to check that the trunk lock cover is
seated correctly around the entire perimeter.
•
Note: Do not force the feeler gauge between the cover and the trunk’s interior trim. It should
slide only if a gap naturally exists.
4. If the 5 mm feeler gauge does not fit between the cover and the interior trim (it stays on the
outside), the vehicle is compliant.
•
No further action is required. The vehicle can be released.

5. If the 5 mm feeler gauge does slide in between the cover and the interior trim indicating a gap
larger than 5 mm—the cover is non-compliant (Not OK).
6. For non-compliant results, replace the cover following the procedure in the workshop manual:
•
Section 9.24.061 – Rear Hood Lock Cover: Removal/Refitting or Replacement
7. Once the replacement is complete, the procedure is finished and the vehicle can be approved.
