Features not working , lack of comfort

I drove 2100 km for a long distance there is a lack of comfort for the driver, dashboard hits the knee while pressing the clutch if the seat is adjusted then the clutch and break not reachable to the feet, due to this knee pain starting for long distance. Central locking not working after 2-3 days. Headlights go down at night while using the power window due to this visibility getting low on the road. Due to this excitement lost in buying my first new car.
