Alfa Romeo bulletin S2418000016
Alfa Romeo filed this with NHTSA as a service bulletin dated Dec 11, 2024, received Dec 10, 2024, about the engine. It names 8 model years (2021–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 43 complaints with NHTSA since 2015. 4 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.
The engine oil cooling system failed on my 2021 Alfa Romeo Stelvio 2.0T at approximately 45,000 miles. The failure caused engine oil to contaminate the engine coolant system, creating a brown/milky “milkshake” substance inside the coolant reservoir and throughout the cooling system.

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 Alfa Romeo S2418000016 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 S2418000016 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.
Which vehicles does S2418000016 cover?
The manufacturer filed it against 8 model years: 2024 Alfa Romeo Giulia, 2023 Alfa Romeo Giulia, 2022 Alfa Romeo Giulia, 2021 Alfa Romeo Giulia, 2024 Alfa Romeo Stelvio, 2023 Alfa Romeo Stelvio and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
