OnStar or undocumented GSM systems in Tesla...

(under Prevention Measures). "After the first 500 Roadsters, Tesla added a remote monitoring system to the vehicles, connecting through AT&T’s GSM-based cellular network. Tesla uses this system to monitor various vehicle metrics including the battery charge levels, as long as the vehicle has the GSM connection activated4 and is within range of AT&T’s network. According to the Tesla service manager, Tesla has used this information on multiple occasions to proactively telephone customers to warn them when their Roadster’s battery was dangerously low. In at least one case, Tesla went even further. The Tesla service manager admitted that, unable to contact an owner by phone, Tesla remotely activated a dying vehicle’s GPS to determine its location and then dispatched Tesla staff to go there. It is not clear if Tesla had obtained this owner’s consent to allow this tracking5, or if the owner is even aware that his vehicle had been tracked. Further, the service manager acknowledged that this use of tracking was not something they generally tell customers about. Going to these lengths could be seen as customer service, but it would also seem to fit with an internal awareness at Tesla of the gravity of the “bricking” problem, and the potentially disastrous public relations and sales fallout that could result from it becoming more broadly known."
