2013 Dodge Avenger Squeeling

I have a 2013 Dodge Avenger that has an intermittent squeal from the front right side of the car. The squeal resemble that of a worn brake pad, however, I have ruled that out as it sometime does it when the car is sitting still. It will do it if I turn the steering wheel all the way to one side or the other. But then again, it will sometime do it as I am driving straight. Took it to a mechanic and he said that its a normal sound when you turn the wheel all the way to one side. I explained to him that it will also do it if I am driving straight. I could tell the guy didn't want to mess with it because he basically just shrugged me off. It isn't normal because I have never had another car do this. Anyway, any help would be greatly appreciated.
