When active cruise control is active the forward collection activates when their are shades and sun breaks in the road. Also when cruise control is activated, the forward colition should slow down and or stop the vehicle whne it approuches a vehicle in front of it. Often when approuching a stoped car etc infront or foward of the telluride it ds not break or slow down, it acts as if their are no obsticials in front of it. I have brought the vehicle to dealer when it had less than 3000 miles for this issue and will be bringing it back again on 1/28/2025 for this reacuring issue. Just today 1/17/25 it happened 7 times within a 5 mile travel.
