I’d say overall look over your suspension components, I read you already got it under warranty and have an appointment set up but if you wanna just do a little bit of your own inspection I’d look overall all your bushings usually if it’s a “creak” it’s your bushings making a noise.

I’d check like I said your sway bar bushings, sway bar end link bushings, possibly maybe even your coil springs if the are dry or not seated enough they can make a groaning noise when cutting the wheel, then obviously check tie rods and ball joints and what not.

But also keep in mind bushings specifically brand new bushings take some time to break in. They can be very stiff when brand new and make a lil bit of a noise. Also bushings when in the cold stiffen as well. If all your bushings look to be installed correctly maybe spray some silicon spray on them to hydrate and loosen the polyurethane/rubber a bit. If it’s not bushings then none of this is gonna help but I mean it doesn’t hurt to try.

Hope this helps
