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 7 model years this bulletin names have filed 2,752 complaints with NHTSA since 2015. 902 of them name 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.
On the 2017 Honda Pilot, the 87 owners who gave an odometer reading for Engine reported it at a median of 55,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
2017 Honda Odyssey Piston ring failure leading to stop spark plug working while driving. This makes car shake heavily and can’t drive more than 20mph, sound from engine is loud. Had been happening every 1000 miles or so, changing spark plug temporary fix it. Spark plug starts failing one after another.

Common questions
Source: NHTSA, 49 CFR 579.5Is Honda AEBM04182025901 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 AEBM04182025901 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 AEBM04182025901 cover?
The manufacturer filed it against 7 model years: 2017 Honda Accord, 2017 Honda Odyssey, 2018 Honda Pilot, 2017 Honda Pilot, 2019 Honda Ridgeline, 2018 Honda Ridgeline and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
