Honda bulletin A25-062
Honda filed this with NHTSA as a service bulletin dated Oct 13, 2025, received Aug 21, 2025, about the engine — 2 documents under this number. It names 5 model years (2017–2021). 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 communicationService Bulletin - Water could enter the hood scoop and accumulate down inside the no. 4 spark plug hole. This can corrode the ignition coil, plug tube, and spark plug, leading to a misfire to the no. 4 cylinder. If a misfire is detected, DTC P0304 is stored.

Common questions
Source: NHTSA, 49 CFR 579.5Is Honda A25-062 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 A25-062 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 A25-062 cover?
The manufacturer filed it against 5 model years: 2021 Honda Civic, 2020 Honda Civic, 2019 Honda Civic, 2018 Honda Civic, 2017 Honda Civic. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
