The 2006 Honda GL1800 has 4 recalls, the most serious being a Takata airbag inflator that can rupture and send metal fragments into the rider, with the risk of serious injury or death.
The remaining recall covers the rear braking system and applies broadly across the GL1800 lineup. A secondary master cylinder in the combined braking system can cause the rear brake to drag after the rider releases it. That drag creates two problems: the unexpected braking force can destabilize the motorcycle and raise the risk of a crash, and if the brake continues dragging over an extended ride, the friction generates enough heat that the rear brake assembly can catch fire. Prior repair attempts did not fully resolve the issue, which is why this brake defect appears across multiple recall campaigns spanning a wide range of model years.
