This has only happened to me a few times in the last couple months, but I have noticed a vibration/grinding feeling in my steering wheel when I hit bumps while turning. It has only happened on highway on/off ramps that are bumpy. Once it happens, the steering wheel feeling doesn't end until I straighten the wheel out. My first guess was the CV or Ball Joints, but I just had them checked two days ago and the shop I brought it to told me they looked fine. However, I don't know how closely they inspected them. I don't get any kind of noise when turning normally and have no indication that any front end components are compromised.

Anybody have and ideas about what could be causing this?

 

I had a 2012 4 dr that did the same thing.. Never found out why... It's traded in now, be interested to know tho
