Dash Wiring problems of the 2004 Land Rover Range Rover

While driving at speed in excess of 60mph the suspension, transmission, driveshafts failed multiple times. Require tow serviced each time due to complete powerfailures. Vehicle locked and forced me into emergency lane on the NJ turnpike. Landrover replaced only the battery and alternator the first time and 3 months later the failure happened again , and they replaced the battery and alternator again. Vehicle has electronic problems I have had speakers,ecu sensors, steering wheel motor, parking sensors all replaced in a 12 month span of a 2 year lease. Landrover will not help me obtain a safe replacement for the remained of my lease.
