2006-Sportivo

Hi Guys, I bought a 2006 MCV36R Sportivo three months ago. It has one annoying feature. Whenever I rest my arm on the door (top or armrest) it's noisy. I've had quite a few cars over the years and none have done this. Just curious if this is a common feature of the model or if it's something that can be corrected. Any feedback you can offer would be most welcome. Cheers.
