If it is a dealer installed mechanism they should have disclosed that information to you. The dealer i bought mine from informed me off a GPS module installed on mine. They do that just in case they have to locate the vehicle for non payment and the buyer tries to hide it. I have no problem with that because i intend to make every payment, and if someone steals it, it can be located. I don't think dealers are allowed to install mechanisms to shut down vehicles anymore. That has proven to be dangerous for the buyer.
