Hmmm...My wifes 07 Trailblazer has Onstar.
We have not activated it, since the vehicle was bought used. I never liked the whole OnStar thing to begin with. A tracking device, like the EZ-Pass toll collection system. They are Transponders.
Perhaps with this story, the driver was using OnStar and sounded drunk and the operator notified authorities? Or someone used it to make the call on the hazardous driver.
I have been thinking about pulling the fuse to the system and disabling it.
We do not use it at all. That is if it is not tied into EVERYTHING in the vehicle to prevent that from happening.
I have a question for Shaun...Oh Shaun...
