Recall 18V173 affects 9,044 2017 Maserati Quattroporte and Ghibli vehicles for unexpected neutral shifts or engine shutdown. Repair is free at any franchised Maserati dealer.
Maserati is recalling 9,044 certain 2017 Quattroporte and Ghibli vehicles because an engine software problem can make the transmission shift into neutral or park at slow speeds, or shut the engine off without warning. That loss of power or gear control raises crash risk in traffic, and Maserati dealers will complete the repair free of charge.

What's wrong?
These 2017 Maserati Quattroporte V6 and Ghibli vehicles use engine control software to manage how the engine and transmission talk to each other. At very low road speed, about 2 miles per hour, the software should keep the engine running and keep the transmission in the selected drive range unless the driver commands a change.
In the recalled software calibration, that control logic does not handle low engine speed correctly. During slow traffic or creeping stops, the transmission can shift into neutral or park, or the engine can shut off without driver input. The remedy software is a newer calibration for the same system, so the dealer repair updates the control program rather than replacing a mechanical part.
There is no warning sign before failure. The first thing an owner notices can be the vehicle losing drive at low speed, the gear indicator changing to neutral or park, or the engine shutting off while moving slowly.

What should I do?

- Contact your nearest franchised Maserati dealer to schedule the free engine-control-module software update that fixes the low-speed shift and shutoff problem.
- Bring the recall notice if Maserati mailed one. If not, reference recall number 18V173 and Maserati recall 365 when you call.
- Avoid unnecessary stop-and-go driving until the software update is complete.
- Call Maserati customer service at 1-877-696-2737 with questions about scheduling or owner notices.
What happens at the repair
At the dealer, a Maserati technician updates the engine control module software so the transmission and engine control logic use the corrected calibration. The dealer work is free under the recall. Maserati did not set up a separate reimbursement program because the affected vehicles were under warranty and owners were not expected to have paid for this repair before the recall notice. If you have prior repair paperwork, ask the service desk how warranty coverage applies.
