Honda bulletin AA29051
Honda filed this with NHTSA as a manufacturer communication dated Aug 4, 2025, received Aug 18, 2025, about the electrical system. It names 7 model years (2023–2026). 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 AA29051 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 AA29051 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 AA29051 cover?
The manufacturer filed it against 7 model years: 2025 Honda Accord, 2024 Honda Accord, 2023 Honda Accord, 2026 Honda CR-V, 2026 Honda Civic, 2025 Honda Civic and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
