Subaru bulletin 15-337-26
Subaru filed this with NHTSA as a service bulletin dated Apr 30, 2026, received May 4, 2026, about the electrical system. It names 11 model years (2016–2026). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Subaru 15-337-26 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 15-337-26 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 15-337-26 cover?
The manufacturer filed it against 11 model years: 2026 Subaru BRZ, 2025 Subaru BRZ, 2024 Subaru BRZ, 2023 Subaru BRZ, 2022 Subaru BRZ, 2020 Subaru BRZ and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
