Subaru bulletin 15-246-19R

Subaru filed this with NHTSA as a service bulletin dated Jun 30, 2026, received Oct 1, 2019, about the electrical system — 20 documents under this number. It names 23 model years (2020–2024). 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.

What the bulletin says

Source: NHTSA's summary of the manufacturer's communication

This Service Information Bulletin outlines a new required procedure to follow when performing immobilizer-related repairs on the all-new 2020 Legacy and Outback. To further enhance vehicle security, this new procedure requires connection to a secure SBR server for authentication and to access immobilizer information. An 8-digit “Authentication Keyâ€� supplied by SBR will be a required input when working with SSM4. Unlike the previous system where Teaching Codes have been unchanged, the new Authentication Key will change every 6 months. This bulletin will be updated with the latest Authentication Key as it becomes available. The new vehicles utilize an Immobilizer Type “Gâ€� or “Hâ€� system depending on model: • G: Vehicles with a turn key ignition switch • H: Keyless Access with Push-Button Start.

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.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Subaru 15-246-19R 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 15-246-19R 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 15-246-19R cover?

The manufacturer filed it against 23 model years: 2024 Subaru Ascent, 2023 Subaru Ascent, 2024 Subaru BRZ, 2023 Subaru BRZ, 2022 Subaru BRZ, 2024 Subaru Crosstrek and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
