Read by machine from the document NHTSA serves (4 pages), read Oct 4, 2026. A part number is shown only where it matches Honda’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 140 complaints with NHTSA since 2015. 21 of them name Fuel/Propulsion System, Engine — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The contact owns a 2025 Honda Civic Hatchback. The contact stated that while driving 55 MPH, the vehicle suddenly shutoff with the check engine warning light flashing on the instrument panel. The contact pulled over to the side of the road and the vehicle was restarted. The warning light was off after the vehicle was restarted.

Common questions
Source: NHTSA, 49 CFR 579.5Is Honda A26-089 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 A26-089 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 Honda warranty extension on file lists the ones Honda has filed.
Which vehicles does A26-089 cover?
The manufacturer filed it against 2 model years: 2026 Honda Civic, 2025 Honda Civic. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
