    Tony,

    The engine will be discontinued in this country because DCX will not invest the money to make it emissions legal. The engine will continue to be available in Europe for sometime to come so parts should be a non-issue.

    The only issue we will all have is finding a good competent diesel tech and a dealer with a really good service department.

    I have moved to Florida from Maryland and am looking for a good dealer in the Delray Beach area. Any suggestions welcome.

    Wheel back on the rear of crd. Talked to a very knowledgeable woman at a parts store. I and the betterhalf (we) are not alone. She has heard a lot of problems with the liberty (she's not biased since she understands the cherokee and wrangler and mechanicals more than some males).

    Without investigating fully, it appears if the crd was to have an upper anti-rattle spring - it didn't have one. Wasn't supposed to or selling dealership mechanic didn't put it back on at the 2k mile grinding noise from hell fix. The anti-rattle slider? slid out and cut grooves in the back of the mag wheel.

    Liberty 2004 made top ten list of worst vehicles. Can the 2005 claim that honor also. No answers please.

    I see posts from pttrillium and winter2 have addressed the support issues, and I agree with their statements. I like my CRD, but if you're going to be overseas for a while I might hesitate as I don't know how long it will take to get italian engine parts for a Jeep shipped to SE Asia or wherever you might be. If you're posted in Europe I wouldn't hesitate at all.

    One thing to consider - you need synthetic 0w40 or 5w40 oil with a diesel rating (CF or higher) in the CRD. Is that available where you are?

    Apart from parts, who is the mechanic to work on it? The diesel system probably requires someone with diesel-specific knowledge. Do you have on-base mechanics? Are they trained only on gas engines or on diesel also? I would think someone who can handle a truck diesel could work on this engine, but I won't say the same for someone who only knows car gasoline engines.

    Other comment - 25k seems like a lot even for a well equipped model. I bought a decently equipped Sport in January for closer to 20k, and that was before they were discontinued. I don't know what kind of deals you can expect as overseas military but 25k doesn't sound like anything special to me.

    I wasn't sure which system the OP was using but surely I had older systems in mind. More modern systems do indeed use high sampling rates with four or more channels to partially offset the significant errors in civilian GPS. :)

    Here's what I was thinking: GPS and Speed Measurements

    Another consideration is that speedometers are often calibrated to display a slightly higher speed than the actual speed for reasons of legal cover.

    In any case, the milepost technique is tried and true.

    I got my Jeep CRD KJ in 2005 and have really liked it despite some problems. The thing cruises well.

    The most recent problem which I've had was the yellow light on the dahboard for potential engine problems was lighting intermittently. I took it to the dealer and they hookede it up to their machine. The codes received were indecypherable to the folks at the dealer. They told me to bring it in if the yellow light comes on again. Dealer support has been good.

    The yellow light did come on again. The engine began to run like it was running on three cylinders. Of course it happened on a Saturday night when no dealer would be available for assistance. I poked around myself and reseated the plug that that "talks" to the fuel injection computer. The Jeep ran fine after messing with the plug and has run well for the last three weeks. So you may expect the yellow check engine light to come on if you procure a CRD Jeep. I wouldn't let a few problems like the "lemon" light (check engine light) stop you from buying a CRD Jeep.

    Note that maintenance is somewhat less frequent for a diesel Jeep than a gas Jeep. This is nice. Note also that mileage is a bit better. This is nice. Diesel engines are supposed to last a long time. This also may be nice.

    The Jeep does have a turbocharger so in Florida you will have to watch for overheating very carefully. Failure of a turbocharger leads to an extremely expensive repair. Expensive repairs are not nice.

    I request that you let the forum know what you've decided. It will be interesting.

    pttrillium: We bought our 2005 Sport CRD Sept.29 05. With in 1 week the diesel rose about 50 cents above reg gas. We traded our 2005 Liberty Limited 3.7 in on the CRD. So we made a very serious venture to get the CRD. After buying it I felt over come by being totally unfamiliar with diesel. There was a lot of conflicting information that was hard to digest. Use Cetane boosters, no use anti gel cetane boosters, no use 15-45 oil, no use 10-30 oil, and so on and so forth. Then reading some very unfortunate buyers complain about various problems. I was really thinking we made a mistake. However, I started calling major dealers that sold large numbers of Jeep Liberty CRD's. I found one dealer in Toledo Ohio, that their Tec also helps in the factory when they have a problem with a stubborn CRD. He has been to Italy, and knows his stuff, even been trained in the factory. I also e-mailed the factory two times for information. So I feel I am caught up enough to be comfortable with our CRD. Id not do any of the work myself. I am blessed to have a excellent dealership and a top notch tec to do my CRD work. So I now am confident we are doing good by the CRD.
    Each person has to make up your own mind if this would be a wise choice for you.
    Our CRD has 19,400 miles in it. I am changing oil every 8,000 miles, I use Shell Rotella 5-40 w Synsethic oil. I do not fit either the A or B schedule, so I sorta split the two. I am under the miles for the schedule A but above the B. I do not use additives, I don't drive it any different than I would a gas Liberty, with the exceptions of letting the engine cool down for a couple of minuets after a long ride. I try not to go over 3,000 rpm except when more power is required. I drive conservatively only because I am not is a huge rush. We go pretty much by the speed limit. Saves money on tickets too.
    I am glad we put on the 100,000 mile extended service contract warranty. Max. care 0 deduct able. With all this I can say I am pleased at 19,400 miles. It costs me 11.7 cents a mile for fuel. I get 22 to 26.1 mpg. Never been on a trip so far.
    Use caution, ask questions, and might even ask the good LORD what His will is for ya.

    My experience is this: bought in 4/05. Now have 33k miles, only 1 repair, EGR, beyond normal maint. I change oil @ 9k (split between a/b service) and use dealer (0-40) oil. I use no additives and start car in winter (coldest -12F) without use of plug in heater. I treat CRD as a car, nothing more, nothing less. It has given me good service (so far) and is "fun" to drive. My usual mpg is around 25 with 80% hiway at 70-75mph. I just finished a 1200 mile trip to northern quebec which included over 300 mi on dirt roads/trails in full time 4wd. CRD performed flawlessly in all conditions. Even during that segment of trip, I still got 22mpg. To give you a good difference between the CRD and other SUVs, my buddy with an explorer had to buy 5 gal of gas from the trip outfitter in order to make it back to main road. At 312 mi I still had plenty of fuel for the trip out.

    Yes the car has its quirks and you do see alot of whining about every squeak and rattle here, but in the main, it has been good to me. I know its a Liberty and I do not expect 300,000 miles just cause it has a diesel. Anyone who does is on drugs.

    So, buy it if you want, but be real in expectation: it is rugged, but not indestructible, nor will you get jetta tdi mileage.
  • faroutfarout Member Posts: 1,609
    vtdog: You and I agree and are almost the same as the way we drive. Except here is we do 70-75 around the lake, we would be in the lake! I personally think additives with this engine might offer some little help, but not enough to notice, except in your wallet!
    By what I read the Jetta TDI has a lot more problems then our CRD will ever think of having!

    Wow,pttrillium, thanks for all the info. I understand a lot more about what you are saying. The only thing, I have looked for information on the drivetrain warrenty and have not found anything. If it is 100,000 miles on the diesel, then I have no worries at all. I guess that was what I was worried about was engine problems..it seems I just need to find a competent mechanic/delaership when I return from overseas. Where do I find info about a star rating?
    once again, thank you very much.
    I will respond to everyone else now as well.
    And we have decided to get the car.. :)
  • tony67sstony67ss Member Posts: 6
    Thanks for the reply, I am in Belgium and they have a great Jeep dealership right now the street. Diesels are everywhere over here. And the oil, I will probably have to order online--I have been researching the proper oil as well, synthetics, etc..
    As far as the price, I have to pay frieght both from Ohio to the port (Baltimore) and then to here in Belgium as well as customs fees.
    So that comes to just over $2200.
    So Basically, the price I mentioned includes all those charges.
    Thanks for the information, and the oil is something I need to check on.
    Best Regards,
    Anthony
  • tony67sstony67ss Member Posts: 6
    Thanks for the information. I think I read another post of your regarding the best type of oil to use, but that is a whole different subject. I will do more research on that as time goes on. If you have any advice on the break in period, as far as what to do, I would appreciate any info you could provide. We will be driving it about 400 miles from the port to my home in Belgium. From what I have read, just dont cruise control and try to vary the RPM's.
    Thanks again for the valuable info,
    Regards,
    Anthony
  • zachinmizachinmi Member Posts: 228
    The price sounds much more reasonable after that explanation. And being in Europe you will almost certainly get better diesel mechanics than we do here in the states. I wouldn't worry too much about the oil - the local Jeep dealer should know what works, whether or not it's in your owner's manual (assuming it's used in the CRD flavor sold to locals). Enjoy your CRD!
  • synlubessynlubes Member Posts: 184
    my 2005 march build crd has always gotten eighteen to nineteen miles par gallon last few tanks have been twenty in town and twenty five on the road more than happy with it plus it is fun to drive nineteen thousand miles on it
  • synlubessynlubes Member Posts: 184
    i happen to be a oil distributor dont worry about the oil is is probably better than most oils in the states i would run synthetic whatever they have there will be fine probably c astro syntec

    The best part of our past crd ownership has been the good people here (including those who took a hit and are not forgotten). The garage now has two generals.

    I do wish you the best of luck. I suspect your vehicle will serve you well - most seem happy with their decisions. I know I am extremely happy with mine. Time will tell in all these things. Stay positive and enjoy your Jeep. Just don't stick your head in the sand ;0)

    Would it not be ironic if the person who buys your CRD does not have a lick of trouble with it? :blush:
  • nescosmonescosmo Member Posts: 453
    Tired-old-dave..... I know that you probably will never read this but I hope that you will not use your H3 because the bad gas mileage that you will get from it. I had an Avalanche bought it on 03 and sold it on o5 with only 3k mile and took a big lost. It had a 5.6 engine and gas consumption was very bad. hope you love your H3 and hope the gas prices will go down so you can enjoy it. GOOD L....

    Ok, last week received the emissions recall. Called today for an appointment. They told me the lower ball joint recall had just appeared online (at the dealership) today. Mine is recalled. BUT, no parts. LOL. They said parts will be slow in coming because it is a massive recall. They hope to have my parts within the next two weeks. Since it's an '06 with only 3500 miles I'm not worried about a couple of weeks or even months. I told them it shudders occasionally. They will check that out as well but also told me it would be officially noted and if nothing was found at this time, it would still be covered even if whatever it is breaks after the warranty period. I don't have the extended warranty but was considering buying it. Maybe I won't need it afterall. My dealership (Claremore Oklahoma) has been beautiful to work with over the past several years and they seems to be just as interested in this vehicle. Incidentally - Love this little jeep! MPG is 24.1 on short trips. No long ones yet.
  • faroutfarout Member Posts: 1,609
    Well with the new ULSD we got 26.4!!!!! I am happy! I notice no other difference. Our CRD has not nor does not now blow any smoke, I have read that other have seen smoke when the punch it, but not even then for us. But 26.1 is stop and go, staying running with air on, while wife is shopping, and driving at 73 for about 70 miles. So that's real nice. For a while I thought the reports of 24mpg were maybe a little over estimated.

    Now some not so good news for our Liberty RENEGADE friends. No Renegade for 2007. Yep it's true, just like no CRD for 2007. What are these DCX boys thinking?
    Diesel is $2.759 in Columbia, Missouri. It's finally looking like we just might see $2.60 a gallon again.....hope.

    my 2006 crd up to now(@2500 miles) has been absolutely awesome! however this weekend it was more like a turd. all of a sudden from nowhere it had zero power & would barely go. after turning it off and back on we were back to normal. today driving down the road every light in the dash went off like i hope to see a slot machine do one day. luckily it only last a minute. the only recall notcie i have received is to reprogram the ecm which i will be promptly getting it to the dodge house first thing. mileage has been 21 no matter what. :lemon: ??? or just one of the hurdles?

    I have a 2005 4x4 diesel Liberty (March production). I'm interested in using biodiesel and have seen the references to the warranty being voided by using higher than 5%. I can find nothing in my owner's manual or warranty book that addresses biodiesel.
  • zachinmizachinmi Member Posts: 228
    I have used a fair bit of B20 with no problems. It sometimes takes longer to start with B20, but once running is as good or better than on petrodiesel.

    There have been a number of posts here and apparently VM Motori rejects warranty claims if over B5 is used. However, the warranty is from DCX, not VM Motori, so I don't care if VM Motori disapproves. Another post indicated that DCX inspects any failed fuel pumps and if scoring marks are found then they assert biodiesel over B5 was used and deny warranty coverage; I don't know if there's any truth in this. I had not yet gotten around to reading the whole manual and warranty book to see if there's anything on biodiesel, but I'm glad to hear that there isn't.

    Biodiesel from reliable sources is used extensively by bus fleets (school and city) and by the US military for non-combat vehicles. Those are pretty strong endorsements in my view. Not a guarantee that it won't cause problems in the CRD, but certainly reassuring to know. I have not heard directly of any biodiesel problems, and the ones I hear of indirectly usually seem to involve homebrew or some problem that Minnesota had last winter with its mandated biodiesel percentage in all diesel sold.

    My two cents - make sure your biodiesel source is reliable and provides clean, good quality fuel. I would and do use B20 without a concern. I personally don't use anything above B20, but I have read on other forums of people using B99 with good results. Your mileage may vary!

    As far as I can tell, there is no ULSD in Middle Tennessee yet. There are two B-20 pumps, one in downtown Nashville, and the other in southern Brentwood. But the price of diesel including B-20 is still in the $2.90 to $3.00 range.

    I think Farout is living a charmed life. We have never averaged over 24 mpg, and that was on a long drive. Fuel economy is now about 21-22 mpg with the check engine light on. I will soon be installing this Jeep's sixth EGR valve. That's an average of one EGR every two months. I keep telling them about the need for a PCM replacement with the EGR, but they kind of just shrug their shoulders, and say that the authorization must come from DCX.

    Pairiegirl- Just FYI we purchased the 6or7 year/75000 premium for just a little on $1200.00 with the $100 deductible. It took 3 dealers and alot of talking to get them down to that price. If you do decide to get the extended warranty maybe this info will help you get a good price on it.

    This happened to my wife a few weeks ago with our '05. In over 12K miles it was the first problem requiring service. It threw a code and the ECM reflash fixed it. I think they may have tightened some hoses, too. Total down time was 4 hours at the dealer. Not too bad for a full year of use and an average of 23 mpg combined.
  • winter2winter2 Member Posts: 1,801
    We must remember that this version of Bluetec does not use the AdBlue liquid.

    Does anyone know which part or parts of the CARB standard the Bluetec diesels failed and by how much?
  • zachinmizachinmi Member Posts: 228
    I doubt that this was the cause of your problem, but just in case... back at the end of June I was in the Colorado mountains near Breckenridge and had a loss of 80% or more of power after a long descent. The Jeep would not accelerate past 25mph and would barely go up hill. We limped to our hotel and the next morning it ran fine. Most likely cause was fuel gelling, as the last 4 tanks of fuel had been purchased in low elevation areas so were likely summer diesel #2 which gels around 32 degrees or maybe even higher. I added an anti-gel fuel additive and had no further problems.

    Again, I doubt this is the cause of your problem, but am tossing it out just in case.
  • winter2winter2 Member Posts: 1,801
    I regularly get 30 to 31 MPG if I keep the speed around 60 to 62 MPH.

    I recently drove to Florida at an average speed of about 72 MPH and got 27+ MPG for a 1025 mile trip.
  • winter2winter2 Member Posts: 1,801
    Keep an eye on the hose clamps. I check them monthly to make sure they remain snug.

    I had a similar incident with my 2005 CRD at 686 miles. While travelling on a local road, it simply died. I was able to coast it over to the shoulder and restart it but whenever I took it over 20 MPH, it would die. It was in Limp-in-mode. A flash of the controller with updated software fixed the issue.

    How many of you have put in the Provent or a racor system (Highly efficient oil separation as a closed as well as an open system providing ideal protection for the turbocharger and other components installed downstream.) I just had my EGR replace again at 20,000 miles and I think the oil blow by is cause of these problems. Has any just gone with a open system? Thanks

    Talked to the better half and its 6yr 75,000 max care for $1200 even. Our 06 sport has been great 2000 miles on it and no problems. 20mpg all city driving. Diesel down to 2.72 a gallon. As far as the EGR problems I also own a 06 Ford PSD and the forum I watch for info, its the same complaints.

    When I investigated service contracts at the DCX website last year, it clearly stated that diesels and turbocharged engines were excluded. The quote below is from the DCX website this morning.

    ULTIMATE CONVENIENCE PACKAGE
    This plan is available with a $0 Deductible on 2005 model year and newer Chrysler, Dodge and Jeep® vehicles covered by a minimum 3/36 Basic Warranty (excluding Crossfire, Viper, Diesels, SRT-10 and all other vehicles that require synethic oil). Vehicles are eligible within 120 days of the original warranty start date.

    In fact, the only contract that I could buy at the time was the Essential Care Service: oil changes (for about $23.00 per service).

    In view of the disclaimer, how are y'all getting these dealers to write and commit to an extended warranty service contract?

    P.S. I wonder what synethic oil is? I thought our CRD oil was synthetic.
  • mdamickmdamick Member Posts: 277
    It has to get a lot colder than you think for fuel to gel-even straight #2.
    Most likely it was a computer screw up. Mine has done it a few times-just shut it off for a minute or so & restart.

    w5mtw: Do not take that the Owners manual says nothing as an approval of Bio fuel higher than 5. DCX does not approve of Bio fuels, but they say B-5 is ok, nothing more.
    Go to http//richard.fortin.free.fr/kj_diesel/Common_Position_Paper_FIE-{producer_0904.- pdf
    Long web address but the information is very important to every Liberty CRD owner. This clearly states why only B-5 is the highest bio fuel to use. This is the exact information V M Motori sent me with a note explaining why to use 5-40w oil.

    bmartinpe: It is so unreal to hear someone say my mileage is hard to believe. I was so convinced my fuel mileage was stuck at 22mpg! It has only been after I hit about 18,500 miles that any noticeable change took place. It was with Murphy (Walmarts gas station) that our mileage increased. So I try to use is as often as I can.
    A s for prices it is all over the place from $3.069 to $2.759 all with in a 50 mile range. I can't understand why the big differences.
    I too believe the Good Lord has blessed us and given us, at least for now a charmed life.
    As for the PCM I think you might consider calling 1800 992 1997 the DCX help line. Tell them what the Yard Jeep Service dept has said that's what they do and never have had to replace one they have R&R the PCM with the EGR. Why does your dealer not call STAR. Something with the Tec that you are using us not right. But according to Dan, at Yark Jeep in Toledo, Ohio,

    eebo: May I tell you what I have done for the last three DCX Extended Service Contract Warranty. I bought the DCX Max Care $ 0 deductible 5 year, 100,000 miles for $1,540. Which is the best I have heard of. Now the best part my payments are $42.78 for 36 months at 0% interest. Here is how to do this. You should have gotten in the mail a offer and a folder from Chrysler Service Contracts offering you the Warranties for several choices of miles and time, and miles. And they finance at no interest. Call the dealer you bought from, and tell them you will pay $100. over their cost for the warranty I told you about. Cost might be a litter higher, but not much. If your dealer says no start calling every DCX dealer you can. One will do it for you.
    I had to convince my dealers finance manager to try it, and he did . From the first time I have done this three times. The issue is the dealer does not get paid until the contract is either paid off or canceled. We had this on our 2004 Dodge Neon, and a Texas Driver pulled in front of our daughter. The Neon was totalled, the contract was cancels, we got back about $80. after paying for 14 months. We have been very pleased with the DCX Service Contracts. we have had more than 11 vehicles with those Contracts and never lost a dime. Hope this helps.

    winter2: Is the CRD doing ok? I hope so. Go to
    www.jeepnewsnow.com?modules/news/ This is known by "MIKES TOTALLY FREE JEEP NEWS" This a a very informative site, it's my second favorite web site next to this one. The California emission standards are what 4 other states go by. So DCX is attempting to pass on CA standards or stay the way they now are. Eventually if CA does not make a standard that Diesel vehicles can meet, they may just find they are going to have a hard time finding vehicles to do the work with the gasoline engines only!
    But with the very odd governor, who signs bills that demand little children to learn things in school that only parents should teach, then why should we expect more than rejection of standards that 45 States agree is good for them?

    bmartinpe- We paid $1100 for the max care and they charged us $100 extra for the diesel. it took 3 dealers to slowly bring down the price. Just make sure you beat on the dealer and call around to get the price down. They did offer to finace the warranty for 0%.
  • winter2winter2 Member Posts: 1,801
    The CRD is running just fine. I have been to the website you have suggested. It does have lots of good information.

    I believe that once Bluetec with the AdBlue liquid is in place, then it should easily pass CARB emissions. Federal emissions rules are going to be very similar if not the same some time down the road.

    The biggest road block to the AdBlue liquid will be the EPA.
  • winter2winter2 Member Posts: 1,801
    I considered a Provent system for some months. I have found an alternate solution in the motor oil I use. I did some serious investigation of the various oils and found that the motor oils recommended by DCX namely the Mobil 1 0W-40 and 5W-40 have high vaporization loss rates in excess of 10% and in some cases approaching 12 to 13 percent.

    I use Amsoil 15W-40 full synthetic oil. Many of it's specs are very close to Mobil 1 5W-40 but the vaporization loss rate is about 6.5%.

    I am presently working in southern Florida and have located a five star dealer with a factory trained CRD mechanic. They have about 30 or 40 CRD customers. Many of them use this same oil because of the heat here and the mechanic stated that DCX does not really care because the oil meets and or exceeds the CI-4 spec. He also stated that he has never seen any engine issues when using this oil, including the Cummins and Powerstroke diesels.

    Wondering about this, as I had assumed it was gelling. I just did some research and can't find anything definitive on the temperature at which #2 diesel gels, but one site suggested -9 C. or so. I realize #2 diesel is a general range rather than one exact compound so there will be a range of gelling temps. When I had the problem we were descending a mountain freeway above 10,000 feet in an air temp no higher than 40 F. and possibly below 30 F. The last two tanks of fuel were from hot dry areas (Grand Junction and Eastern Colorado) so were presumably #2 diesel with no anti-gelling additives. The symptom was simply a severe loss of power, but no other behavior and no warning lights. I have not had any similar problem before or since, and have not had any computer related problems, which makes me still tend to think a fuel gelling issue (perhaps filter plugging?). However, it does appear that the outside temperature was well above a typical fuel gelling temperature. Any thoughts?
