2018 Volvo S90 shuts down in Eco mode

My s90 just got little over 600 miles and the check engine is on . What I notice while driving the vehicle is that the Eco mode or Comfort positions does not work properly , the car should shot down the engine when complete stop. The check engine is on , I going to the dealership. Very frustrated with the situation

Sure it is frustrating but most likely the warranty will take care of this . Is that a misprint ( 600 miles on a 2018 ) . Also when the check engine light is on certain functions will not work , that is normal.

No is not a misprint, the vehicle has only 635 mile , just purchased on feb. 15
