What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationThe purpose of this document is to provide guidelines for managing concerns regarding oil leakage from the side/axle seals of the rear differential. In these cases, it is recommended to replace only the oil seals instead of the entire assembly. This procedure is permitted only for Levante vehicles, both within and beyond the warranty period. BOL opening as “Factory Information” is required with pictures of the leakage before proceeding with the seal replacement.

What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 31 complaints with NHTSA since 2015. 13 of them name Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
While driving at low speeds, under 5mph, the car will shift itself into neutral. This happens while slowing, coasting, or slow accelerations. This has caused an immediate safety issue as you lose control of the car, especially when the shift into neutral is a hard shift.

I’ve owned this car since Jan 2021. Throughout this time the car will show the exact problems mentioned in the Maserati Recall 338. The car will shut off while I’m in traffic, or if I’m slowly going through a yield sign the car will unexpectedly shift into neutral.
2017 Maserati Levante · Engine · filed with NHTSA Aug 13, 2024 · ODI 11608174
A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Maserati MAS004067 MTB 24-23 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the MAS004067 MTB 24-23 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.

The manufacturer filed it against 9 model years: 2024 Maserati Levante, 2023 Maserati Levante, 2022 Maserati Levante, 2021 Maserati Levante, 2020 Maserati Levante, 2019 Maserati Levante and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
