Yes many of us here have faced the issue of AC system failing, claiming warranty and having the part replaced.
As for the steering, the same goes, have the dealer checked and claim for warranty (I have too) and before that, record a video of the issue at home or elsewhere in the event it doesn’t reoccur on the day of inspection. Please explain what kind of sound you hear? I hear a clanking clicking noise mostly when I do a full circle or close to it.
