Power Steering Pump problems of the 2016 Subaru Crosstrek

While driving at night around curves at about 15-20 mph the steering wheel kind of locked, and could not go back straight. Had to stop, turn the car off in order to the steering wheel feel normal. It did it a couple of times, also while parking it made like a clicking noise by the front passenger wheel. Had it fix, Subaru replace relief valve, electric oil pump. Even though Subaru is at fault, I had to pay almost $600 to have this fix because my car had a condition that was not covered by their warranty. It isn't fair. I bought this Subaru because of their reliability. It shouldn't have defects. This situation exposed my daughter's life and mine. I hope nobody else goes through this risky situation. Thank you.
