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.
One page for every brand it was filed under. Each brand’s bulletins: Jeep · Ram · Dodge · Chrysler · Alfa Romeo.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communication"CANISTER Vapor -If an issue is detected with the Evaporative System Integrity Module (ESIM) Detector and not the Vapor Canister, only replace the ESIM Detector. -Before replacing the Vapor Canister due to Hard to Fill condition, replicate the condition at the Gas Station. If the condition is replicated, then check: 1) for kinked or pinched Clean Air Hose between the ESIM and the EVAP Air Filter; 2) for plugged EVAP Air Filter; 3) for kinked or pinched Vapor Hose between the Fuel Tank and the Vapor Canister. If the EVAP Filter is restricted, the replace the Filter. -Check if the Vapor Canister is flooded with fuel or the Recirculation Line has fuel. If fuel is found in the Vapor Canister or the Recirculation Line, then drop the Fuel Tank, remove the FDM Lock Ring to check if the internal Vapor Line is properly connected to the FDM Port. If the Vapor Line is not connected, then drain the fuel from the internal Vapor Line and properly connect to the FDM. Replace the Vapor Canister and the ESIM."

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Stellantis 9100471 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 9100471 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 9100471 cover?
The manufacturer filed it against 84 model years across 5 brands (Jeep, Ram, Dodge, Chrysler and Alfa Romeo): 2025 Alfa Romeo Giulia, 2024 Alfa Romeo Giulia, 2023 Alfa Romeo Giulia, 2022 Alfa Romeo Giulia, 2021 Alfa Romeo Giulia, 2020 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.
