Honda bulletin AATS31549
Honda filed this with NHTSA as a manufacturer communication dated Aug 31, 2026, received Sep 2, 2026, about the electrical system. It names 5 model years (2018–2022). A manufacturer communication 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; the full text comes from the manufacturer or a dealer. 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. Quote it at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Honda AATS31549 a recall?
No. A manufacturer communication 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 AATS31549 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 AATS31549 cover?
The manufacturer filed it against 5 model years: 2022 Honda Accord, 2021 Honda Accord, 2020 Honda Accord, 2019 Honda Accord, 2018 Honda Accord. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
