Yeah, here is a snippet of their last update with link:

Sales of the Jeep Liberty CRD turbo-diesel have exceeded expectations and that's great news. It's about time Americans got more familiar with the efficient diesel engines that are common in sport-utility vehicles sold in Europe.
The bad news is that production for the Jeep Liberty diesel has stopped. The current 2.8-liter doesn't meet new emission rules. So, you either have to settle for one on a dealer's lot, or wait for a diesel Jeep Grand Cherokee due next year.
The Liberty was a test of the acceptance of diesel SUVs in America. We certainly accepted our 2005 Liberty which has been fault free a full year and 18,000 miles. Our overall test results of 21.9 miles per gallon may be only 10% better than a V6 gas Liberty, but it exceeded 28 miles per gallon on the highway.
So, while the 11,000 Liberty diesels may only be a drop in the bucket now, maybe that trickle will turn into a steady stream, as even more efficient diesel engines prove that you don't have to give up power for economy in an SUV.
