Problem Honda (American Honda Motor Co.) is recalling certain 2018 Honda Civic vehicles. The manufacturing date area of the certification labels may have random characters which can affect the owner's ability to determine if a safety recall includes their vehicle. Risk If the owner is not able to verify if their vehicle is involved in safety recall, it can increase the risk of injury or crash. Fix Honda will notify owners, and dealers will replace the certification label, free of charge. The recall began August 7, 2018. Owners may contact Honda customer service at 1-888-234-2138.

Two numbers, one recall

Every safety recall carries two identifiers. U23 is the number Honda assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 18V421000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.

Check one specific vehicle

Both lookups check a VIN against the manufacturer’s own list and say whether the repair is still outstanding on that vehicle.
