I have a 2005 Jeep Liberty CRD with the GDE tune and other minor mods. Overall not a bad vehicle, but not the fountain of economy that I expected. Looking forward to looking at the new Grand Cherokee diesel but having owned one now for a while I will be more knowledable regarding my decision.
Hi I am an Australia jeep diesel owner with the new grand cherokee. I have had a wide range of diesel jeeps in the past including wrangler, patriot, liberty/cherokee and yes all with diesels. I am being told we will also be getting the new cherokee in diesel here in Australia this year with a Alpha 4 cylinder good for 50 mpg and with stop start technology. It will become the family second car when it arrives.
I'm about to do my 2nd timing belt at 200K. If Jeep does the job their book rate is 6.3 hours I believe and you can buy a parts kit from idparts.com for around $400, so the total should be in the $12-1300 range. I'm also a fan of the eco tune, had mine for 160,000 of my 200,000 miles. Itow a lot so Iput in the heavy duty torque converter, but my daughter still has the stock in her CRDHave had an 05 Liberty CRD for about 3 yrs. Not the greatest mileage. Had some stupid little issues early on, but now its at 96k. I did find out something interesting. I priced the Timing Belt/Water pump/pullies replacement at 100k... The dealer who knows the most about CRD around me here in the DC area quoted me approx. $2400 for the work. My brother-in-law priced it near him at between $700-1000 (western Ohio).
This thing smokes like a champ.... Much more than the other 3 diesels I own.
Still debating the GDE Eco Tune. But have the re-flash and stock(orig) Torque converter. My youngest daughter will be driving it as her daily shortly.
Had the GDC about a month now and love it. Averaging about 26 mpg so far.
Just turned 20k miles on my 2014 Overland JGC diesel with no problems other than some minor interior rattles, which I hear may be caused by the extra bit of vibration from the diesel engine. Had a couple of minor recall items handled with recent service, but so far so good.
