Software problems of the 2017 Land Rover Range Rover Sport

Vehicle has several electrical problems. The board will go black screen while driving. I took it to the dealer 2 times for the same problem, and they told me that they will contact me with a software update. It never happened. I dont have time to take a car to the dealer every week. It is a new car. I leased it on Sep. It would indicate malfunction engine light last time. The vehicle stopped in the middle of the road. I would start the engine and would not shift gear. I had to drive the vehicle mannually at 5 miles per hour to my house. The tow truck took my car 2 weeks ago to the dealer. The car is under repairs. No luck as to what is going on. Today they called that are changing the fuel pump. Waiting for the part and after installation they see if the problems are resolved.
