I just heard on the news that cars with Onstar that are stolen, may not be able to be traced for location. What the car theives are doing is immediately after stealing it, they drive it into a steel-boxed truck cutting off the tracking signal! Kinda like when you are on a cell phone and you go into an elevator. Has anyone else heard about this? I was just starting to think theft would be one reason I would have Onstar. I guess there is a way around everything.
