Honda filed this with NHTSA as a service bulletin dated Dec 12, 2023, received Dec 23, 2023, about the power train. It names 2 model years (2023). 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.

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 857 complaints with NHTSA since 2015. 42 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.
I purchased a new 2023 Honda Accord from Woodland Hills Honda on 1/20/24. On 1/23/24, I pull into my garage after driving home from work and turn off the car. I get out to an overwhelming smell of gasoline. I inspect the car for visible leaks, which I don’t see, but the gasoline fumes kept growing and spreading throughout my garage.

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 AATS231201 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 AATS231201 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 AATS231201 cover?
The manufacturer filed it against 2 model years: 2023 Honda Accord, 2023 Honda CR-V. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
