2016–2023 Acura and Honda: structure recall
Failure of rear suspension components, such as the rear control arm, can cause a loss of vehicle handling and control, increasing the risk of a crash or injury.
What was reported
Source: manufacturer filing, 49 CFR Part 573Reported to NHTSA Jun 4, 2026 by Honda (American Honda Motor Co.).
What that means, in plain English
Source: WhichTrim's reading of the filing above — not NHTSA's wordingCorrosion-induced rear subframe failure can cause loss of suspension integrity and vehicle handling, which can lead to a crash, but the filing describes a gradual corrosion process rather than a sudden, complete loss of control, and no stop-drive order was issued.
Written for us by a language model from the manufacturer's filed text, which is quoted in full above. Where the two differ, the filing is the record and this is only our summary of it.
The fix, from the dealer bulletin
Source: NHTSA remedy instructions and dealer noticeThe remedy, in the manufacturer’s words: Install the rear subframe reinforcement kit.
The advisory, as filed: “Next Unread Message View Message DATE: June 5, 2026 TO: All Honda Sales, Service & Parts Managers, and Personnel FROM: Erik Blank, Manager of Auto Campaigns and Recalls Re: Stop Sale/Safety Recall: 2016-2023 Multi-Model Rear Subframe Corrosion.”
Read from NHTSA’s copy of the manufacturer’s dealer documents (manufacturer campaign AOU, AOT). The procedure itself is in the bulletin; a franchised dealer has the current copy on the manufacturer’s portal, and that copy governs. Working a lot or a fleet? Recall Watch carries this line on every VIN it checks: remedy status, hours, stop-sale.
Which vehicles are covered

Those are the model years inside WhichTrim's range, 2016 onward. The campaign may cover others outside it, and the only thing that settles whether one specific vehicle is included is its VIN.

Check one specific vehicle
A recall applies to a build range, so year, make and model cannot settle it. Type the VIN and the WhichTrim recall report checks this campaign’s build window and engine against it.

Common questions
Source: NHTSA, 49 CFR Part 573Is AOU, AOT the same recall as 26V365000?
Yes. AOU, AOT is the number Honda (American Honda Motor Co.) uses for this campaign in its own paperwork and in the letter it sends owners. 26V365000 is the number NHTSA files it under. One recall, two references — dealers and service departments generally quote the manufacturer's.
Does this recall repair cost anything?
No. Federal law requires the manufacturer to remedy a safety defect or a compliance failure at no charge, for vehicles up to 15 years old measured from the date of first sale. A dealer that asks you to pay for a recall repair is in the wrong.
How do I know whether my vehicle is included?
By VIN, not by model year. This campaign covers vehicles built May 4, 2015 to Jan 10, 2023. The manufacturer files a build range with NHTSA and only vehicles inside it are covered, so two identical-looking cars from the same year can differ. NHTSA's own lookup checks a VIN against the manufacturer's list.
What if the repair is not available yet?
It happens, and often. Manufacturers must notify owners when a defect is found even if the parts or the software are not ready, then notify them a second time once the remedy exists. This campaign was filed without a repair available — Honda (American Honda Motor Co.) says so in the text above.
What did the manufacturer say was wrong?
The problem, risk and fix quoted on this page are the manufacturer's own words as filed with NHTSA under 49 CFR Part 573. WhichTrim does not paraphrase them.
Who started this recall?
NHTSA's record credits the manufacturer. A recall can begin with the manufacturer's own testing, with a defect investigation, or with a compliance test against a Federal Motor Vehicle Safety Standard.
