Bought my 2008 last October & found out about the recall, but it was already replaced. However, when checking, I found out there was another recall, here it is, don't know if its applicable to other years, although I am the 3 owner, they did still did honor the recall & replaced my switch:
"Certain affected motorcycles may have the ignition switch lead wire that is improperly routed. Handlebar movement can result in abnormal flexing and damage to the ignition switch lead wire.
Damage to the ignition switch lead wire can result in intermittent or complete loss of electrical power, which can result in loss of lighting and/or stalling of the engine. This could result in a crash.
Suzuki dealers will thoroughly inspect the ignition switch lead wire routing. If the ignition switch lead wire is not routed or clamped properly, the dealer will replace the ignition switch/lead wire assembly. The original lock set will be installed onto the new ignition switch/lead wire assembly so that the original key will operate the ignition switch.
