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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Honda ONL6EY09192024 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 ONL6EY09192024 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 ONL6EY09192024 cover?
The manufacturer filed it against 1 model year: 2023 Honda Accord. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
