GM and Chrysler aren't the only one with ignition issues. Harley-Davidson is recalling over 3,300 bikes that could switch from "on" to "accessory" because of excessive vibration.
According to the recall notice, the issue affects 2014.5 FXDL Dyna Low Rider bikes made between January 6 and June 19, 2014. Apparently a factory modification that allows the engine to rev past 5,600 rpm sends enough vibration through the engine mount to shake the ignition switch and move the key position.
Harley noticed the defect after four warranty complaints were filed by customers and an investigation by its service department. The fix involves a bracket assembly and ignition switch knob, both of which H-D will replace for free.
