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 17 model years this bulletin names have filed 6,892 complaints with NHTSA since 2015. 77 of them name Structure — 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 2016 Honda Pilot, the 28 owners who gave an odometer reading for Structure reported it at a median of 26,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2017 Honda Pilot. While the vehicle was stationary, the contact noticed mold in the rear seats and in the folds of the doors. Honda of kirkland dealer located at 12420 ne 85th st, kirkland, wa 98033 diagnosed that water entered into the vehicle through a sealant gap of the firewall behind the dashboard.

There are some major electrical issues going on with this vehicle. The tailgate locks and will not open so we are not able to access the bed of the truck or the trunk in the bed. Also, the vehicle locks itself occasionally even with the key inside. The USB / plugs in the back seat of the vehicle do not work.

I have a 2016 Honda Pilot elite and I noticed on my last road trip that the hood on the vehicle moves violently when I pass on coming vehicles especially large trucks. I also noticed that this happens during high wind situations as well. I made a service appointment for this week to address this with Honda.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Honda A24-048 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 A24-048 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 A24-048 cover?
The manufacturer filed it against 17 model years: 2022 Honda Passport, 2021 Honda Passport, 2020 Honda Passport, 2019 Honda Passport, 2022 Honda Pilot, 2021 Honda Pilot and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
