What it saysThe Replacement BCM Front Harness Is Not The Same As The Original NHTSA’s full summary ↓
Alfa Romeo filed this with NHTSA as a service bulletin dated Jul 21, 2023, received Sep 25, 2023, about the electrical system. It names 7 model years (2017–2023). 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 7 model years this bulletin names have filed 271 complaints with NHTSA since 2015. 71 of them name Electrical System — 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 contact owns a 2017 Alfa Romeo Giulia. The contact stated while driving at various speeds, the vehicle would suddenly shut off. During the failure, the check engine and auto stop/start warning lights were illuminated. The vehicle was taken to the local dealer who diagnosed that an unknown relay needed to be replaced.
2017 Alfa Romeo Giulia · Electrical System · filed with NHTSA Jun 25, 2021 · ODI 11422256
The vehicle intermittently fails to start or stop when using the Start/Stop push button. This is a critical safety concern. If the vehicle cannot be reliably started or stopped, and its ignition system operates unpredictably, it may fail during use, in traffic, or fail to respond in emergency scenarios.
2022 Alfa Romeo Giulia · Electrical System · filed with NHTSA Oct 28, 2025 · ODI 11695964
Due to a faulty starter relay, my Alfa Romeo Giulia would intermittently not start or restart. The dashboard illuminated properly but the starter did not engage and the engine did not attempt to crank. Afterwards, a warning lamp would sometimes appear saying "auto start/stop unavailable".
2019 Alfa Romeo Giulia · Electrical System · filed with NHTSA Oct 21, 2021 · ODI 11437604
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 S2308000089 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 S2308000089 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. Every Stellantis warranty extension on file lists the ones Stellantis has filed.
Which vehicles does S2308000089 cover?
The manufacturer filed it against 7 model years: 2023 Alfa Romeo Giulia, 2022 Alfa Romeo Giulia, 2021 Alfa Romeo Giulia, 2020 Alfa Romeo Giulia, 2019 Alfa Romeo Giulia, 2018 Alfa Romeo Giulia and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
