Child Safety Lock Failure notice — both parked or driving, I will hear a clicking noise coming from the doors. Sometimes I will receive a Child Safety Lock Failure error message on the dash. This would sporadically continue to happen while driving and even if my vehicle is parked and off and I happen to do something like open the doors. The vehicle has been serviced numerous times by Hyundai dealership and the door actuators have been replaced but the problem persists.
