Thank you for your feedback John. Sounds like an auto start-stop system is turned off which automatically shuts off your engine when you come to a stop. You can refer your owner's manual to find out how to turn that off. We encourage you to visit your local authorized Hyundai dealership for further inspection regarding computer going off. If you have any questions or concerns after the dealership visit, please contact our customer connect center at (800) 633-5151. Thank you ^cc.
