Why does the EPB and auto hold light keep coming on my 2013 optima

This is a new car. First check the manual for an answer. Next call the dealer you bought it from & ask for the saleman who sold it to you. Ask the sale person the same questions, If you can't get an answer, take the car back to the dealer & let them figure it out.

epb stands for eletronic parking brake and the auto hold feature is for holding the car stopped on a hill so you dont have to keep your foot on the brake.both lights come on because the auto hold feature is turned on on the vehicle. there should be a switch somewhere to the left of the steering wheel on the dash to turn this off if you like
