New vehicle with under 4,000 miles was being driven on a busy parkway when the engine suddenly stalled and would not restart. No visible warning lights prior to stall. Incident occurred just past the top of a hill, creating the potential for a rear-end collision. A police officer was called and arrived, parking behind the stalled vehicle with emergency lights flashing in order to prevent a collision. The driver of the vehicle tried repeatedly, 5 or 6 times to use the vehicle's built-in roadside assistance to get help but got disconnected every time before a tow truck could be dispatched. Vehicle was in the middle of the highway for over 20 minutes. Dealer confirmed engine has seized and has to be replaced.
