    Wow, 12.5mpg tops in a 4x2 1500? That's terrible. The 2500 4x4 does feel quite huge - I can actually look over a Suburban's roof from the driver's seat! It is a wonderful truck, but I would find it a bit big for a daily driver (though my wife uses it that way - she rarely ventures downtown). We got it to pull a horse trailer (5000lbs empty, up to 10,000 loaded) and it is absolutely wonderful for that purpose. We have been getting 14-15mpg pulling that trailer at 70mph, both on flatland and up and down hills!

    I have used, on my light gray fabric Jeep seats, a car upholstery cleaning product that I think is from 3M and claims to contain teflon. It appears to spot right when you use it, but after it dries there are no spots. I'll try to look up the exact name later.

    caribou1: My ball joints have no shield. The cap is a siler like metal, Mine were checked yesterday, and no problem....yet. The tec said the shield is to prevent heat transfer. So far they have not seen a Liberty with ball joint problems this year. $6.25 a gallon? Oh that's gota hurt! With this war news in the east maybe it will get close to that.

    Hi Farout,
    There was a tv report about a family travelling all over the world with a diesel camper. When in Iran, they said to have paid one US dime for a gallon (2 cts of a Euro per liter). Are we paying for their fuel?
    These people had an IVECO-Fiat common rail, they didn't seem to suffer from poor fuel quality. I wouldn't dare taking my Jeep out there without special precautions!

    I was talking to a mechanic at Van City RV in St. Louis when we stopped to see the Sprinter Van Conversions while on vacation earlier this week. He said that one of their customers who had an engineering background had a Liberty CRD, and became frustrated with the frequent EGR change outs. This customer apparently developed a plate with which he could divert the soot from the EGR and keep it from clogging up and staying stuck open. The customer was supposed to have been in consultation with DC about his solution.

    The Van City mechanic appeared to be knowledgeable about the EGR challenge. I asked him if there were any issues with the Mercedes five cylinder. He replied that the 2002 and 2003 Sprinter models had problems, but that the models from 2004 and on appeared to have worked the issues out.

    I have a Liberty Sport built 05/2005 achieving 20-21.5 mpg in every day mixed driving. I am on my fourth EGR valve and have replaced one glow plug that had a hairline crack.

    You may recall my post about having to replace (both) fuel pressure regulators a couple months ago. The problem (intermittent cutting out of the engine and finally completely cutting out) occurred again today, about 1000 miles after the repair. Took it back to same mechanic, a good diesel mechanic I believe. He didn't trust the computer when it said one of the two new regulators was bad. By chance (and experience I think) he shook the wiring harness and voila! the engine died. Repeated 7 or 8 times with same result so we've concluded there is a short in the harness and he'll either find/fix it or put in a new harness. Funny the computer doesn't sense these things apparently - it just said the regulator wasn't working.

    winter2: Am I correct you live in Canada? I seem to remember you using the km after some milage, or am I wrong. I find using the Metric system is rather amusing. I have been to Mexico City several times and the Metric System is used there. So when some one says they were doing 100 that's only 60mph here. It's neat to me anyway.

    tailgate: Hey I was not sure if more than two of us had CRD's in MO. We are here on Lake of the Ozarks, where are you located? We have the tan interior, and keeping it clean is a real chore. Now to prevent the satins that's a new idea. We have not given that much thought.

    In the Mopar book about CRD goodies (the same as the 3.7 Liberty) they have some rubber mats that look pretty good.

    Hi Budsip,

    When data is out of range on a component an error code(s) is stored by the computer for retrieval and probably a light is turned on. If a wire to a sensor or component is open or shorted it would be seen as data out of range. So, in a sense the computer is reading either the component or sometimes the wire.

    I find your experience interesting in the context of the earlier post by Bmartinpe who is unbelievably on his 4th EGR valve.

    Bmartinpe, was any follow up done to verify that the EGR valves were actually bad? Could it be a bad wiring harness creating EGR error codes also. This would be a monumental diagnostic screw up if components are being replaced because of intermittent problems with wiring harnesses.

    caribou1: I would expect a Jeeps life or for that matter any vehicle, to last more than a year in Iran would be a risky and in Iraq it would be fool hardy.
    While at my dealer today and the tec whom I feel is pretty up on the CRD said after the warranty is out, the repair cost will be unafordable, unless your rich. Now that made my day! I am so hacked off with DCX! If anyone doubts we are a test market, than I don't know how much more it will take to prove it.
    At least Caribou1 can get parts. Are parts there very expensive, or do you know? I am really begining to feel really dumb to have bought this CRD, I wish I couls see some light at the end of the tunnel. And soon!

    I live in the Rolla Area. I know there are at least 2 other CRD units seen fairly regularly around town. I was missed one having his muffler replaced at a local muffler shop. The guys replacing the muffler told me they didnt even know the Liberty was a Diesel, cause the owner told them what he wanted, part # etc, so the guys doing the work on the Liberty had to do no research, and had no Idea there was a diesel under the hood, and started it up (after they replaced the muffler), heard the vehicle run, but it just didn't sound quit right to them (for a gasshopper), then they open the hood, in order to trace down the problem, and got enlighten. A week earlier, I told the owner of the Muffler Shop, that some of the Libertys had Diesels, then he remembered, and connected the dots. Bingo..."this is what Tailgate was talking about, he bought one of these Libertys, he wasn't pulling our leg after all".

    Being There to see that.....Priceless. Needless to say, they were impressed with the discovery. Dont worry about Resale, the interest in big.

    The mechanic verified that the valves were dirty with soot and stuck open. Plus, when my check engine light came on, my mpg began to suffer.

    Some observations:

    Have not taken off the hoses to see any effect of the oil change. Are yours staying clean. I am assuming you are still stock-muffler, airbox and your mileage is well below 20K.

    Some post had a used buyer from Houston's crd fail in NM and the wife is flying home today because the TC is a week away. Ours still can't handle the torque except going downhill. The new TC's are in stock in the Dallas warehouse and we are trying to buy it and the front pump and the rest of the kit and not send trash through the tranny. But the dark side of me says - let it trash everything, try not to get stranded on a dark interstate night far from home and get a new CAC.

    Got my front tires balanced by the local tire dealer-took tires one by one in the trunk of the malibu - some idiot there believes in jacking up the front end by the lower control arm. Will be buying BFG's at discount next time. While there saw a 239K 4cyl chrysler minvan getting an alignment and a jeep GC getting new rear springs.

    Went to Mike's off road (did my tranny skid plate) and asked about receiver fixes. The man thought I was nuts. He then put a ball mount into the receiver and saw the slop. I am also still trying to resolve the hollow tube used on the jack kit under the seat-used it once and don't trust it for a second use.

    I think it was an australian post that had the fix for the noise in the drivers seat when someone is straddling you. Pulled the rubber molding off the rear drivers side door chassis frame and found some pathetic foam goo at the corner - used multiple layers of duct tape along the top half of the frame after other products failed. Will test it this weekend.

    Look at your tranny coolant lines for rubbing at the bottom radiator brace-Iam going to use a split rubber hose-couldn't find stand-offs.

    Good luck winter2, just trying to head off any problems for you and I am seriously not trying to be condescending. I know how you want this to be your crd. I waited too long for my half-ton diesel and I guess I should've been born in another country. If this post rubs you wrong - I hope it doesn't - I honestly wish all the good people well - I will continue to be silent and listen to the bs like at lost about the air intake and here about what do youhang on your mirror. I always thought jeeps were - - -.

    If we buy a new gm soon, I can't let someone buy ours unless it is better than the way dcx sold it to us. We are not that type of people.

    I apologize to everyone here at edmunds for using this as my personal email to winter2 but we go back quite a bit and are civil posters compared to some on the net.
  • nescosmonescosmo Member Posts: 453
    Farout.... Look at the difference between the gaser and the diesel; How many parts does the gaser has that can go wrong and how many parts the diesel have that can go wrong. If you look it at it on the diesel you can count the parts with your hand think about it. it is a new product and we all are afraid ever the dealer. after the ULSD settle down we all going to see the [non-permissible content removed] and the US build more diesel. I would said withing three years or so.
  • budinctbudinct Member Posts: 21
    I am looking to purchase a new CRD and I am not thinking negatively about the product being dc. In fact, I feel it is an opportunity to get a good deal. If I can get one for $20K, I know that in 4 years it will be worth about $5000 but I will have put 100K miles and hopefully take advantage of good MPG and the utility of it. I will take my chance with parts but in 4 years it should be supported sufficiently enough. Longer than 4 years, I would be wary. The resale value will certainly be lousy.

  • faroutfarout Member Posts: 1,609
    nescosmo: I am not as optimistic as you are. There is nothing else in the US that has a V M MOTORI diesel in a vehicle is there? Even right now price a turbo on this, or even the egr, or a glo-plug. Now add freight, and labor...wow. I do not do any work on vehicles (I am disabled) so that labor is something I cant fight. I finally got an oil change down to $56.00, and that's a $36. savings.
    do not have confidence in DCX to do the right thing by us when something happens after 100,000 miles are hit then DCX is free and clear. We can't get anything out of the customer care line but "I am sorry to hear that." What hope have we that this engine will not have more egr or other major problems? I think we are stuck with a CRD that will drop in value so even trading it in will be a loss so huge we will not be able to dump it anywhere. I got a quote on a 2006 CRD yesterday a Sport window sticker $28300. for $21200. That's a huge drop and it's brand new.

    and for &7k under retail? wow, that's very interesting to me. i might be replacing/trading due to one of my TDIs it being maybe totalled by hailstorm.
    i think pre-2007 diesels are going to remain quite desirable especially after folks see some of the extra $ and possible hassles that the 2007s & later might bring...
  • pttrilliumpttrillium Member Posts: 62
    Here's my opinion for what it's worth. Resale value on any vehicle is pretty lousy. The exceptions are some Hondas and Toyotas but, while they are very desirable cars, don't interest me in the least.

    I have been in this position before with a rare car that everyone predicted doom and gloom about and until I got this CRD, was my favorite out of 15 cars and trucks I've owned.

    That car was a 1986 Merkur XR4Ti. It had a custom intercooler and Borla stainless exhaust that I added. I had it up to 148 miles an hour on a closed road and clocked 145,000 very very happy miles with it.

    I never really had trouble getting parts or service in the years I owned it. I had a couple of big bills around 100,000 miles but hey, it was a German Ford.

    I'm not saying this CRD is going to break or lose value like a rock over a cliff, but my opinion is that I don't care and you should buy and drive cars you love.

    My CRD makes me very happy.
  • winter2winter2 Member Posts: 1,801
    Dave,

    I see nothing offensive in your post.

    I will be breaking the 11K barrier shortly. I still have all the stock items you mention in place. As to the hoses, they are remaining the same. The amount of black goo in them has not worsened and it fact is beginning to dry out. It is much less sticky than a month ago. I have no oil leaks anywhere, not even on the turbo housing or the hoses. Everything is bone dry.

    Sorry you are having difficulty with the trans and the TC. BTW, what is CAC? I will check the trans coolant lines after dinner to make sure there are no problems. Thanks for the heads up.

    Dave, if there is one thing you are, you are not condescending. I enjoy sharing with you and others in this forum.

    As for tires, good luck with the BFG tires. Which ones are you getting? I like my Bridgestone Alenza tires. Very nice rain tire and very good dry pavement tire. After these are worn out, I will go back to either Yokohama GS-51's or Pirelli tires. The Bridgestones are just a bit number than I like (not enough road feel transmitted).
  • faroutfarout Member Posts: 1,609
    tired old dave: Hey dude, I doubt you are older than me but, you have nothing to apologize for what so ever!!!! By what I think I hear you say, we are in a similar position. I don't dislike the CRD, it's well made (I hope) and the engine so far with us, is doing well. What kicks me in the rear of my pants, is that (at least we were) led to believe this would be an on going CRD for sometime. We assumed this would be a huge increase in mpg over the gas 3.7, which turned out with the increase in diesel fuel costs we spend more than the gas 3.7. We traded in a 2005 Liberty Limited that had almost everything, for this Sport CRD that lacks much of what we had in the Limited. So we have some buyers remorse, and all the rest just adds to this feeling of (test marketitest" being taken.
    Dave have you looked at the GoodYear Wrangler Silent Armor tires? I have these tires and they are the very first GoodYear tires I have ever bought, as all the GoodYear tires that have come with the new vehicle are usually not fit for the road, in my opinion. But these Silent Armor tires are quiet, smooth and good in snow, ice, gravel, and rain. To find a tire that does all these things well is really great I think. Take a look, can't hurt to look.

  • zachinmizachinmi Member Posts: 228
    Farout, while I share your concerns, I think you're dwelling on the wrong issue. I agree that parts availability and the honoring of the warranty, especially for the EGR valve and transmission, are very important and raise a few worries. However, as long as parts are available and the warranty is honored, I see no reason to care whether we were a test market or not, or how many/few CRDs were sold. I had a Honda Accord with a transmission failure at 26,000 miles and had to wait several days for a replacement, despite it being one of the most common vehicles on the road. My concern, which could happen with most any make (as proven by my Honda!) is having the vehicle out of service for a few days and either being without wheels or paying through the nose for a rental car. But apart from that, I'm not too excited.

    arvman,

    From a vehicle quality point of view, I'm happy with my Limited. As I've stated before, I traded in a full size pickup for this Jeep, so I'm having some trouble making the size adjustment, but that has nothing to do with the quality of the Jeep. I bought the Jeep, in fact I went looking for the Jeep, knowing full well that it was a DCX Test. Frankly it was kinda hard not to know that if you were reading about it at all. From the beginning in 2004 DCX was very clear in almost everything that I've ever read that this was a test to see if the demand existed in the US for Diesel. Most of the reviews I've read reiterated that point. In fact they stated that they planned to build only 5000 units. That number was increased later. Now whether or not the increase to 11,000 units was part of the plan and was just a bit of marketing, we'll never know. ... but if you were doing any sort of research before buying then it has always been pretty clear that this was a market test. I really don't mean to offend anyone, I'm just wondering where this sudden realization that we are part of a marketing test comes from.

    So, aside from really missing my pickup (yes I am considering trading for a cummins powered RAM) the Limited has been great. Sure is a blast to drive.

    arvman: I basically like the vehicle, and other than, 3 fuel gauge sending units, 5 ECU & PCM reflashes, a PCM, 2 front passenger seat belts, two front door weather gaskets, egr cooling hose, seat covers came loose, all this took 10 trips to the dealer in 16,600 miles and 10 months. Conidering we live more than 50 miles from the dealer these trips do take time and it takes at least 1 hour to get there. Thursday I was wating in the customer waitingroom from 9AM until 5:17PM, which makes a very long day for a guy who is older than dave and dirt as well.
    I do not expect more than nit picky stuff to go wrong with the CRD, but we bought this thinking it would last as long as our 96 Dodge Neon which has almost 187,000 miles on the orignal engine. I see this problem of unnpredictable cost and availability of CRD parts as areal concern for retired people like us.
    I too hope to keep this CRD for many moons as we counted on, but I have my doubts, until I see someone with 100,000 miles or more on their CRD,.....cheers back.

    You couldn't ask for a happier guy, Arvman.

    The Jeep Liberty CRD was a gift to the American automotive public. The CRD has a unique combination of capabilities and qualities that do not exist in any other vehicle. It also has a unique combination of minor irritating qualities that have been overly beaten with a rubber hose. H@ll, we&#146;ve beaten the hoses with a rubber hose.

    Everything that I read prior to the introduction of the CRD said that DC would be subsidizing its production just to get it out there because diesel is the future. The limited break-even production run could not have made DC much money. If quality was shaved a little on some parts, DC is paying for it in warrantee work now.

    We were never a test market in the sense that we were beta testers of the vehicle itself. If anything, the introduction of the CRD was a test of the acceptability of a different class of affordable diesel than previously existed. DC passed the test by introducing a unique and very useful vehicle. The American public failed the test by not buying a great vehicle as ravenously as they buy many utterly useless and incapable vehicles (in my opinion).

    ULSD availability has dramatically affected decisions of diesel vehicle manufacturers in different ways even though they all saw it coming. For example, VW opted not to produce a 2007 diesel Jetta, but produced extra 2006 units to help fill the gap. Furthermore, VW could not introduce a 2007 mid-year in 2006 because ULSD was not available except for California (maybe a few other places) where it was and is illegal to buy a new diesel! The DC decision is not that much different from VW&#146;s decision. Even the new diesel Grand Cherokee is a 2007 and a half. DC could not introduce a 2007 GC because for all practical purposes there was no fuel mid-2006!

    Some of the hand wringing on parts availability is unwarranted. Accessories like air conditioner compressor and alternator rotate much slower than average and should last longer on this diesel than on almost any gasser. The rest of the vehicle, except for the engine, is standard off-the-shelf Mopar. If you take care of an engine it will take care of you. We could find ourselves knee deep in common rail fuel system parts at local parts stores as diesels become more prevalent a few years down the road.

    I have spent a lot of time discussing some of the problems because I thought the discussions were interesting, not because I don't like the vehicle.
  • arvmanarvman Member Posts: 95
    Well eveyone it seems many of us are on the same page.I too went from a full size e-cab pickup to the CRD.I had the advantage of knowing this engine's predecessor from an overseas tour in 2001.We had 2 vehicles in camp with motori's and the only problems were people putting gas in them.Despite the problems some of us have had,(hopefully these will get rectified under warranty)we should get good use from this rig.I agree we should keep each other informed as to potential problems and experiences.I'll be going through the rockies at the end of the month so I should get to put her through the paces on some nice hills.

    03/05 Build date CRD bought in central MO. Now moved to KS.

    EGR @ 16,500

    Transmission @ 25,890

    DCX - after much work on my part picked up rental car for week while Torque converter and Transmission kit installed.

    Typical millage - 21

    Following DCX maintenance schedule exactly.

    Seats stain with water like all others.

    Currently 31,000 miles. Hope ULSD helps.

    Anyone know what the valve on top left of radiator is. Haven't moved it, but curious what it controls.

    Occasionally will start and stall and hard to restart unless I prime the fuel pump again. Haven't scoured the list to see what these symptoms indicate. Did catch some discussion earlier this month on some fuel system issues.

    Don't know much about common rail injection but it sounds like your suckin air big time,maybe take a quick look underneath and inspect the fuel lines as much as you can when it's shut down to see any leakage.Make sure the filters are on tight too...

    CAC - charge air cooler. I guess it is also known as intercooler. The alenza's have 18k miles on them. Pressured to 35psi, all wearing the same with only one front to back rotation after ~5k miles. But the center grooves were 1/32 more worn than the outer other grooves. Down to 6/32 and 7/32. Back to 33psi. Bought yoko's when they came out for the ford van-sipes don't go all the way through and after some wear, just as slippery as the michelin's. Loved p77's years ago. Considered scorpions but never bought them. Revo's seem to outlast the KO's but I don't think we will need to buy a set of tires for this vehicle again.
  • tired_old_davetired_old_dave Member Posts: 710
    You are right. Just shy of SS checks (if it stays in place).

    Had goodyear rs-a on a ford and the st's here. I like the idea of kevlar but it seems goodyear always has a marketing breakthrough and overpriced. One repair shop owner used goodyear but always bought new tires when they were half worn.

    Better half drove for a short trip yesterday. She drove it liked she owned it. I had stopped all additives in the fuel. Even with this high heat the evic was showing 23-25. Fueled up and came back with a true 21. She is fed up but can't stomach the thought of paying cash to someone to get rid of this. We think of you. I may take my own advice and buy a disposable cheap korean suv. But more likely, another push rod from the general.

    I'm interested in trading my 2002 limited for a diesel. Drove a 2006 and didn't like the clatter. I'm waiting to see if they're going to put in some soundproofing in the dash. Is this a lost cause??
    Any info appreciated.
  • zachinmizachinmi Member Posts: 228
    That's normal, and if DCX could stop it for a reasonable price they would. Part of their excuse in the Car and Driver test was that the turbo is so close to the firewall that there isn't much room for soundproofing. I don't know how true that is, but I would take it as a sign that the dealership isn't even go to try to reduce the sound level. The noise is there but I never find it annoying. Noise levels go down with:
    -break-in of the engine
    -premium (higher cetane) fuel
    -biodiesel blend fuel (B20)

    Running B20 the "diesel crackling" mostly goes away and it sounds almost like a gas engine, though not one up to 2006 expectations for noise level.

    I have used Pirelli Scorpion AT tires on my Dakota 4X2. Very good all around tire and quiet in spite of aggressive tread design. Howl a little in the rain, especially when there is tons of water on the road. Scorpions tend to ride more harshly than other tires I have used but make up for it in significantly improved handling and control.

    Yoko GS-51 tires are different. Grooves and sipes are deep and go right to the outside and inside tread. Never had any wet control issues with them.

    Yes, I think there is a 2007 Diesel Liberty, but only if you plan to buy it and drive it in Europe. If you go to Toledo, you will be able to watch 2007 Liberty CRD's rolling out the door before they are put on a railcar and then a ship to be delivered to some happy driver in England or Germany, or France.

ULSD will have lower sulfur (lower acid build up in the oil and combustion system which "may" prevent future EGR valve failures and extend oil drain intervals) and slightly higher cetane (improve startability and quiet the combustion noise). USLD is required by and for the medium and heavy duty Diesel engines for 2007 that will have Diesel Particulate Filters (DPF). The ULSD will prevent "sulfur poisoning" of the catalyst in the exhaust aftertreatment system. ULSD will also have slightly lower BTU content resulting in possible lower fuel mileage. ULSD has been in use in several states since May 2006. I just came from a meeting in Minnesota and all on-highway Diesel fuel being sold today is ULSD (2% bio added which is renewable and adds lubricity). It looks like the cost of ULSD is only going to be a few pennies more per gallon than current LSD (500ppm) fuel. CJ-4 oil is going to be about $1 more per gallon of oil over the current CI-4+ oil.

    ULSD will cost more and result in equal to or lower fuel mileage. Tell me again what ULSD does to help our CRDs. Thanks!

    Saberia... I try to reason with this guy but could not, thank you to see it my way.

    I had a chevrolet avalache with every thing that you could think of, It was a 2003 it was the best but trade it for the liberty it was a big difference; I had only 3000 miles on it and I trade it because the mileage and I am happy that I did I research the liberty and I knew what I was buying so thank you and I think that we are the few and at the end we will be proud. :)

    joornn: The oil in the CRD is Mobil 1 0-40w. If you were to go to a 5-40w the clatter you hear will last less than a minuet. But 15-40w is not within the guide lines of V M Motori the maker of the CRD, and DCX says not to use it. There is a big difference of opinion on this, but this is how I believe is best. This engine is pretty typical of most diesels as I have noticed. Good luck and welcome to the forum.

    Anyone know what the valve on top left of radiator is. Haven't moved it, but curious what it controls.

    Dave, if you mean left while facing the vehicle? I think that it is a radiator fill plug that is removable, since the actual radiator cap is on the recovery tank instead of the radiator.

    Farmer,

    Your post pretty much has all of the answers in it.

    S15 will help the EGR problem in a few ways. Less sulfur, less PM/soot and that impacts on the EGR valve directly and should and probably will result in fewer EGR issues.

    Higher cetane also results in a faster and cleaner burn thus reducing PM/soot. In removing the sulfur by whatever process is used, many of the aromatic substances are also removed. These aromatics may contribute some energy but they also contribute some very nasty substances when burned called PAH (polycyclic aromatic hydrocarbons) which are potent carcinogens. It will be nice to get rid of them.

    I have been using S15 for the past several tankfuls. Here is what I have observed.

    1. Almost no exhaust odor whereas I had some before.
    2. Less knocking/nailing.
    3. No impact/change in FE or performance.
    4. Less smoke under load. Had practically none to begin with.
    5. Starting, no change except a little quieter when cold.
    6. Less vibration at idle once warmed up.
    7. No sagging in the first 100 feet after first start of the day.
    8. Cost: about three cents more per gallon, but still cheaper than gasoline (2.899 versus 3.159).

    winter2 - Thanks for the additional information and also the personal observations.

    I am near Canton, OH and use BP Supreme. I do not know of any ULSD in my area. The fuel price was $2.959 on Friday when I filled the tank (regular gasoline was $3.059). Diesel fuel has been bouncing between $2.999 and $2.959 the past several weeks.

    6700 miles, no problems, and keeping my fingers crossed! :D
