2018 LAND ROVER RANGE ROVER EVOQUE Steering Problems

When traveling on [XXX] in New York, at 78 mph, my 2018 Range Rover Evoque experienced an electronic power steering rack failure I had just picked up my neighbors from the airport and were on the way home. When traveling on a smooth, straight highway, the audible notification alerted and a message on the dash appeared stating "power steering reduced". When just trying to change lanes on the straight highway I would feel the strong resistance. When exiting the Interstate my neighbor sitting in the passenger seat even helped me with turning the wheel on the exit ramp. We manage to make it back to my driveway. My wife normally drives this vehicle and if it was her driving at the time of the failure in our more rural area, there is no doubt she would not have been able to steer and would have crashed with a high possibility...

When I reverse in cold outside temperatures there is a very loud squealing noise. When turning wheel slowly left or right there is a loud grinding noise that gets louder when pressing the gas. When I turn the heater on over 2 notches a loud buzzing whistling sound gets louder the higher I turn the heater on. I have taken it to Land Rover and they tell me they couldn’t find anything wrong but there is definitely something wrong.
