have a 09 jeep grand cherokee and I am getting a metallic or carbon order into the cab. It seems to be worse on the drivers side and if the car sits for a day or two with the windows up in the garage, when you open the doors it smells like burnt plastic really bad. I have had it into 2 different dealers and both say they can't find anything wrong. Now they won't even look at it. I had a 2008 and everything was fine with that one until I had to have a ESM valve replaced and then it started having an odor as well. I traded it in for the 2009 and still getting an carbon odor smell. Any help would be greatly appreciated.
