My question. Since the computer for the Hemi was changed in 2006 to allow a higher engine compression (leaner engine) before injecting additional fuel, why hasn't a TSB been issued to allow a reflash for the 2005 models, which due to this issue suffer from a lack of compression and thus the ability to crawl down steep grades smoothly? This is a safety issue as well as a "black eye" for the Jeep name in an era of competitive vehicles touting downhill assist control.
Besides some hardware differences between '05 & '06 preventing it, flashing a different engine calibration in a vehicle is not permitted unless it is covered by an emissions certification.

Although the WK CRD seems to be listed at top dollar (on the Limited), I have interest, in part as a tow vehicle for my TJ. I'd also like to see the CRD offered on the Laredo (Jeep.com does not now say that it does, but I thought at one time it did?).

Also, I test drove a KJ CRD and loved the torque! Thanks for visiting with us!

The Jeep Grand Cherokee diesel has just begun to hit Jeep dealers. At this time most of our efforts are focused via the Web.

The diesel engine will be offered on both the Limited and Overland models. While, we can't discuss specific numbers, we will be able to meet consumer demand.

If you love the KJ CRD -- you'll really love the Jeep Grand Cherokee diesel with its best-in-class torque and towing.

Thanks for your interest

Coming from a 2001 WJ I had the same initial feeling--hard seats. They are now much more comfortable than my 2001. They are GREAT seats IMO!

The 5.7L engine has canted valves and some valvetrain noise is typical with this type of valve arrangement due to the forces applied to the valve stem by the rocker - not only do you have downward force, but some side-loading as well. Rest assured, it will not result in any issues as the engine accrues miles.

Are they ever planning on putting the spare tire back inside like the WJ?
And is a SFA ever going to return?

Would not the emissions certification for the '06 apply to the '05, or are there other considerations/issues?

On this note, and in light of other 3.7L with a QTII option offerred on the Off-Road Package...QDII is out of the question but QTII is doable since it has already been offered?? Please correct me if I'm wrong.

Thanks for giving us this opportunity.

I am running larger tires 285/70/17. How do I get my speedometer correct?

Thanks in advance

A question per the Tow/Haul switch mode... does engaging this ("Overdrive off") simply lock the transmission out of 5th gear and nothing else, or are other shift parameters changed as well?

I thought my wife's leather seats in her '04 KJ were a bit stiff at first, but I really like them now. Just needed to be broke in.

Remember, we're dealing with the Federal government on this and they are not flexible. A Certificate of Conformity is very specific about the model year. Were we to do a reflash without proper emissions certification, DCX and/or the dealer would be subject to non-compliance fines.

The dealer can only recalibrate for factory size tires. So it is possible to go from a 235/65R17 to a 245/65R17 for example, but nothing larger.

As you mentioned, it will lock the transmission out of 5th gear, but it also utilizes a revised shift schedule for improved towing performance.
