What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationOwner Notification Letter - Your vehicle may be equipped with an improperly functioning on-board emission-related diagnostic system that violates California and Federal standards and regulations. While transitioning from hybrid mode (engine on) to EV mode, a software programming error results in the PGM-FI ECU resetting and inappropriately erasing stored memory data in the PGM-FI ECU. In some cases, the Malfunction Indicator Lamp (MIL) may be set as a result.

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 FE6 a recall?
No. A emissions 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 FE6 repair free?
A emissions communication is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does FE6 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.
