OnStar 'ignition block' disables stolen vehicles

OnStar, General Motors' in-vehicle safety and communications system, has launched a service to keep car thieves from starting a vehicle that has been reported stolen. As of July 20, three stolen cars had been disabled by the technology, called "remote ignition block." The feature is available on select 2009 and 2010 GM models. Subscribers must report their vehicles stolen to police officials and request assistance from OnStar, which then sends a signal that prevents the car from restarting.
