Is the active grill shutter on 2021 Rogue equiped with a motor or actuator? My check engine light is on and the dealer is telling he cannot erase the code since the grill shutter needs to be replaced. I am wondering if there is an actuator to be replaced instead of the whole grill. I had some snow and ice stuck in there this winter and they were able to erase the code. Now they cannot erase it...strange. Obviously the grill shutter were not tested during real winter conditions. I hate that when engineers do not fully test their products. I guess that is why they recommend to never buy a vehicle in its first year.
