Radio/tape Cd Player problems of the 2018 Land Rover Range Rover

The infotainment meant system which is the brains of the car is constantly failing to operate properly. The screen freezes leaving inability to control a/c, radio, bluetooth phone, climate, back up cameras. This vehicle has 4500 miles on it and has been in for service 3 times, it is now back at the deal a 4th time. The computer is erratic and constantly needs to updated. There have been 4 updates since I have owned the vehicle which was in Feb 2018. Landrover is fully aware of the issues but refuses to do anything about it. I have tried repurchase and replacement, which was denied and now I have to go to arbitration with the state lemon law. The cars computer is an epic failure and crosses over to most of the 2018 landrovers . These failures happen at any time , they have occurred while stopped at lights, in standstill traffic, when turning the car on, or just when driving. There is always another surprise waiting when I get in my car.
