The 2003 Honda GL1800 has 2 recalls, both centered on the same brake defect: the rear brake can continue dragging after the rider releases it, raising the risk of a crash and, with extended riding, enough heat buildup to start a fire.
The combined braking system's secondary master cylinder can fail to fully release the rear brake, leaving it partially applied without the rider's input. This drag slows the motorcycle unexpectedly and, if the condition persists over distance, the friction can generate enough heat to ignite the brake components.
