2016 Buick Enclave Steering problems

Was driving my car and went to turn into the gas station. When I tried to turn it was a loud whirring sound. I took it back to where I bought it. I haven't even owned the car for 30 days yet. They said power steering fluid was leaking. They checked to see if it was coming from pump or hose and it was from the pump. So had to replace power steering pump. Got my car back last night and the steering still feels off it isn't making the whirring noise now. It is so hard to explain. It feels bouncy when you make a right turn I guess you could call it. The car makes a squeaking noise when turning as well and they couldn't figure out why.

Power steering has started failing when turning, making it extremely hard to turn the steering wheel. Seems worse at slow speed. Happens whenever and wherever I try to turn the steering wheel. Will drive okay when going straight. Made appointment for service. I suspect power steering pump needs replaced, but just guessing.

I have a 2016 buick enclave - the have exceeded my warranty by approximately by approximately 7,000 miles noticed that the vehicle had begun making squealing sound mainly when turning. Took it to my local mechanic and he confirmed a leak from the power steering hose. He found that there is a published service bulletin regarding the issue. I feel this should be covered under a warranty or a recall.
