On 2/4/2022 this vehicle was picked up from Rockville Mercedes Dealership Mercedes-Benz of Rockville Centre (Service Center) (516) 766-6900. The vehicle was brought in for service regarding error lights and service lights. I was driving the vehicle from dealership back to my home and was unable to stop my vehicle and ran a traffic light and crashed into a Northwell Hospital building. The vehicle errored out on the road stating "Vehicle Malfunction" and i was unable to STOP my vehicle. I've contacted Mercedes and the local shop regarding this and no follow-up contact was made.
