American Honda Motor Co., Inc. (AHM) is actively investigating reports of an oil leak originating from the head cover gasket in certain 2022-2023 Honda Civic models. This initiative, identified as a "Request for Parts: 2022-2023 Civic Head Cover Leak (ACTION REQUIRED)" communication to dealerships, aims to gather specific vehicle components to better understand the underlying cause of this condition.

What Honda is Investigating

Honda's Technical Information & Support Group is seeking to collect parts from vehicles exhibiting a confirmed oil leak from the head cover area. This data collection is crucial for engineers to analyze the components and determine why the head cover gasket may be failing. The goal is to develop a comprehensive understanding of the issue before any repair procedures are finalized or broader actions are taken.

What Owners Should Do

If you own a 2022-2023 Honda Civic and suspect you have a Honda Civic head cover leak that meets the above criteria, you should contact your authorized Honda dealership. While this communication is directed at dealership personnel, they are the point of contact for owners whose vehicles might qualify for this investigation. Do not attempt to repair the leak yourself or have an independent shop replace the head cover gasket if you believe your vehicle could be part of this program, as Honda wishes to collect original parts.

Important Information for Dealerships

Dealership personnel who identify a vehicle matching these qualifiers are instructed to email Technical Information & Support (TIS) at [email protected] or call 800-880-1072 (Monday-Friday, 7am-5pm PST). TIS will then provide further instructions and record specific vehicle information. The email to TIS should include the Model Year, Model Name, Issue (e.g., "Head Cover Leak"), and VIN in the title. The email body must contain the Dealer Number, your Name, Best Phone Number, Current Mileage, confirmation that the vehicle meets all qualifiers, and attached wide-angle and close-up photos of the leaking area, along with the DPTS#.

As a gesture of appreciation, Honda will provide a VISA gift card to dealership personnel who successfully identify and report a qualifying vehicle that is accepted as a candidate for parts collection.
