I honestly can't think of a reason to buy a KL over other vehicles, and I think that is it's biggest problem. It is simply too expensive, not capable enough, and doesn't get good enough fuel mileage to seriously consider it over other vehicles. There is likely a very limited market for the combination of capabilities and price that the KL has.
It isn't much more capable than a Subaru Forester. I honestly think the Subaru actually has a better AWD system, since the KL lacks a true 50/50 split mode and only engages the rear axle when the front wheels slip (even the Trailhawk has this system). Non-Trailhawks don't offer anything capability wise-over the Subaru (in fact the Subaru is probably more capable than most trims of the KL) and the Trailhawk only offers a slight increase in capability for a $10k+ premium. Plus the Subaru is cheaper and gets better gas mileage than the KL.
Conversely for only a few grand more you can get a WK2 which is more capable, is offered with true 4WD and a real transfer-case, has better fit and finish, has greater towing capacity, has better engine options, and is just an overall better vehicle.
If you are looking for capability and aren't concerned about gas mileage you could get an Xtera or 4-door Wrangler for about the same price as the KL.
If you aren't concerned about capability at all and just want a cross-over you could get a RAV4, CRV, Equinox, Escape, etc. for the same price or less.
I really just don't see where the KL fits and it seems there are better options for just about every need.
The Patriot has a market because it is cheap and relatively capable making it a good "budget" option , the KL simply doesn't offer much to distinguish itself over competitive vehicles and the price is too high for what it does offer.
