Sorry, I was never notified someone replied to this.
All of it. The cloth especially. The plastic gets a white haze to it. The dealer was going to replace all the panels but at the time I figured it would be the same. I'm out of warranty now for the interior. It's been 3 years.
If my skin is dry and rub up against the door panels or seats, the cloth turns white. I have the black and charcoal interior.
