Honda GL1800, GL1800A and 5 more models

Certain motorcycles equipped with combined-brake systems have a proportioning control valve (pcv) that mechanically proportions brake force when the rear brake is applied.

Source: NHTSA data as of September 22, 2026. Last refreshed Sep 23, 2026, 2:43 AM UTC.

Summary
Certain motorcycles equipped with combined-brake systems have a proportioning control valve (pcv) that mechanically proportions brake force when the rear brake is applied. A seal in some pcvs is improperly shaped, and brake fluid leakage may occur.
Consequence
If the motorcycle continues to be used after a leak occurs, the rear brake would eventually become inoperative. A loss of rear brake force could increase the risk of a crash.
Remedy
Dealers will inspect the rear brake forleakage. If leakage is confirmed, the dealer will replace the pcv free of charge. The recall began on January 31, 2005. Owners may contact Honda at 866-784-1870.

Honda recall NO.P65.CUSTOMERS may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to http://www.safercar.gov.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Honda been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. Recall repairs are free.
