NHTSA Complaint #11529070 — 2014 HYUNDAI ELANTRA

While driving over the last month, the car shuts off with no warning. There are no check engine or other lights that come on once it shuts down. There does not appear to be any consistency in the occurences, sometimes while idling, sometimes while driving 40 mph. Up until recently, the car would restart once I put it in neutral, but it now does not restart right away.
