Here's my honest opinion. This issue came with the dash redesign in 2011. So, August 2010 is when people started seeing this. They aren't going to fix it. Compared to other problems, this is such a minor issue. If something like this bothers you, consider stepping out of the Wrangler and into something else.
Chrysler has some of the worst QA out of the major car manufacturers and the Wrangler is the bottom of their priority list. You're LUCKY to only have that issue.
