Stopped in a right turn lane with a vehicle in front of me stopped. It 1as a right turn with a yield sign. The vehicle in front of me started turning and pulling away, I rolled forward at about 8mph and looked left. The vehicle that was in front of me had stopped after beginning to pull away. I didn't notice. I rear ended the vehicle a white newer body style town and country mini van set up with a rear wheel chair ramp like the Braun style vans. My right front of bumper close to the emblem on the hood contacted the left rear bumper of the van. I'd say the whole left side of emblem over to edge of vehicle. No airbag deployment. But the forward collision warning didn't go off and the AEB SYSTEM also did not engage. The system seems to be functioning properly. There is no warning lights on the dash. And the system has activated before, both the forward collision warning and the AEB. The following day while turning around on a dead ened street, the forward collision warning engaged the chime whenni got close to another vehicle. The system has engage early before, the dealer checked for codes a long time ago after complaining about early.or false engagements. The vehicle is stated to be inspected by hyundai this week. The current mileage is 49,000. The vehicle has never been in an accident before this. It is going in to check the electronic parking brake system as we have had faults in the auto hold system where it faults and stops working and a light does come on the dash
