I have had my 2003 Sorento EX for 2 months now. I noticed when I first got it, there was a slight vibration in the steering when taking off. It looks like it would only do it when the car was cold. Now it seems like anytime you park the car for a while and get back in and go to take off it does it. I asked the guy at the dealership and he said this was normal. Seemed like he knew what I was talking about. It seems like it is beginning to do it more frequent but only when taking off. Anyone else experienced this?
