GMC, in an effort to give their vehicles more appeal to consumers, will begin offering an “OnStar Vehicle Diagnostics” program for free, where GM will remotely scan your vehicle for problems once a month via it’s OnStar system.

GM has had this ability for a while, however it was always “On Request”. OnStar is already automatically notified in the event of an airbag deployment, and can remotely unlock your vehicle. While this seems handy, I am interested if anyone here fears the security implications of the OnStar system’s power?
