It's pretty bad how Chrylser has let their poor quality make it to the Jeep brand. My parents have had brand new jeeps since 1985 ... they're going to replace the wrangler with a Ford most likely.

Folks with 3.8L minivans have had cylinder heads and pistons replaced. Sometimes that cures the problem, and sometimes it doesn't. Sometimes a new long block is installed and that always fixes it.
1 qt / 750 is considered normal for this engine

Of course, when you have the quality control that Chrysler (doesn't) have, engines with 60k burning oil and knocking *are* normal.
What a horrible organization.
My obvious advice is to take it to another dealer. Exactly how much oil does it use? Has the mandated maintenance been performed at the proper intervals?
I've called other dealers, they don't seem interested. It burns 1 quart per 500 miles. Or when they run it down the highway (such as coming out to see me), it'll drink a quart in about 350. We've also seen small bits of metal come up on the dip stick.
