Hi everyone. I have a 2012 Infiniti G37x that I purchased back in October of 2015. As of late, when I am going around 15-30 MPH, when I take a left turn, there is a weird humming/whining noise coming from my steering column. I tried looking online and found a few things about this. I checked my steering fluid and it is at the max level. Would this be covered under my CPO warranty? What about my extended elite warranty? I am asking because my local dealership seems to beat around the bush when I ask about these questions. I never get a straight answer and I feel like I am being screwed around with.

P.S. I read through what is covered in the CPO booklet and do not see steering being covered or not covered; it don't see any mention of it.
