Yes. If your vehicle is stolen, alert authorities and file a police report. When you do so, let law enforcement know you have OnStar. An OnStar Advisor can use GPS technology to help law enforcement locate your vehicle. If your vehicle is stationary, OnStar can tell police where to find it and send a Remote Ignition Block signal to keep the engine from restarting.
Once your vehicle is recovered, the Advisor or police will contact you and let you know when and where you can retrieve your vehicle.
