    I bought my '05 Liberty Sport CRD at Dave Smith Motors. They are a HUGE Dodge dealer, but their Jeep inventory isn't as big. Don't get me wrong, there are probably over a hundred Jeeps on the lots at any time (most of the town is made up of Dave Smith lots), but they have many more Dodges in stock than Jeeps. They also sell GM products. There were probably ten Sport CRDs in their stock when I bought mine in May '05.

    Great place to shop, though. Very fast, no BS. When I bought my '02 GMC Sierra there, I was in and out with a new vehicle in about 45 minutes, including trade-in and financing. The Liberty took a little longer, but not much. Amazing, compared to what purchases are like at other dealers.

    As you mentioned, they don't have a searchable inventory on-line any more (they did in 2002). It's annoying, and I wish they'd go back to the old system.

    My disclaimers: I don't work for them and they don't pay me to say good things about them. Just a happy customer - even if the CRD is turning out to be an orphan.

    "Be sure and have a " chase car "

    Thanks for the chuckle. I just made that chase car statement to my better half this afternoon when she mentioned out of town. Then I showed her how we couldn't get out of our shadow with the tranny now - and have to wait until it blows to get help from dcx when the parts are available. It feels like the 50's and 60's slushmatic - rpm's but you almost get rear-ended.

    Showed the better half the fully loaded silverado with tow package and yes even though we know tow means 3.73 and 4.10 the maroney said 3.23 locking rear dif. She loved it just looking at it. Mileage is continuing to drop as the tranny continues not to be a tranny.

    I'll be between vancouver island and kamloops,about a 4 hour drive from vancouver.there is a long hill called the coquihala pass that's known to be a tranny killer on many a vehicle so I'll recce dealerships in the towns along the way .I'm almost hoping this thing will blow,kind of crazy maybe,but the thing's been workin great so we'll see,won't be till next weekend(oops).Guess it will be crunch time on that trip.Just have to cover the bases as best as I can and hope for the best.

    Good evening all. Found the forum about a week after buying my 06 crd and have been reading every day since. Have learned alot from the group. I also own a 06 Ford PSD and have been reading another forum on them and am hearing alot of the same issues on that site. EGR,Turbo's and Trans problems. I have friends that have PSD's and have been thru many EGR's. So I don't think its just a DC issue. I hope mine will be worry free, but i don't think it will right along with my Ford

    I think I have said most of what I have wanted to say on this board. Each person has to make their own decision and spend their time and money their own way. I just think people should have full disclosure about this vehicle. It is a great idea - I bought into it. But the reality has been nothing like the fantasy. I don't have the time or the patience to deal with this poorly tested vehicle and have the desire and money to do soemthing about it. So for me, reliability and my time are far more important than loyalty. I refuse to stick by a brand that has not stuck by me. I will pay cash for my next vehicle and move on. Since I work on a mountain at a ski resort I need a vehicle I can count on. I am doing my homework, researching the boards, and feel good about my decision. If you would research some of these other brands as I have, you would find out that others (like Hyundai) do have good resale and are atually the third highest quality car company out there according to JD Powers. #1 is Porche, #2 is Lexus, #3 is Hyundai, #4 is Toyota, #5Jaguar, #6Honda, #7 Cadillac, #8 Infiniti, #9 GMC #10 Acura, #11 Chrysler, #12Lincoln, #13 Nissan, #14 Chevrolet - the rest are below the industry average. Jeep ended up 33rd out of 39. Jeep has 50% more problems per 100 vehicles manufactored than Hyundai. Their warranty is half of Hyundai. I really don't care if others like or agree with my decisions, just do your research before making your decisions and comments. I personally hope the new diesel technologies work because I think they are a great alternative for US car buyers - I just don't want to be part of the research pool. Someone else can do that! For the moment I am still a CRD owner and will continue to read the board until next week when I expect to bail on my diesel affair. I suspect many of you will be ok with the transmission issue because you don't place much of demand on your vehicles. I believe it was the driving up and down the mountain every day that found the weak link in the powertrain and caused it to break. If you aren't having problems with this vehicle - stick with it. If you are, then make your own decision based upon research and your own personal priorities.
    Good luck..... :)

    I will try not to make this a Ford vs. something else war, but for what it's worth Dodge proudly advertises that the Cummins (at least for 2006) does not have EGR as they didn't need it for emissions. It also doesn't have glowplugs. I have a 2006 Ram 2500/Cummins along with my CRD and the Ram has been trouble free and so far worry-free. It's a shame our CRDs aren't free of EGR.
  • nescosmonescosmo Member Posts: 453
    New2diesel.... I am very sorry that your experience was so bad it was fun while you were here. I had a 2001 santa fe and it was a lemon, front end problem, timing jumping, tranny problem ,brakes an so the story goes. If you want a good vehicle get a Honda, they are good. For me the vehicle is as good as the dealer the worse dealer on earth is the Land Rover so I wish you well......

    "Since I work on a mountain at a ski resort I need a vehicle I can count on. ...according to JD Powers. ..."

    Because you are still reading, and other reasons. Please don't buy until after the middle of August. Don't put so much faith in JD.

    Take your reasoning to ad absurdum, think outside the box etc. My request to you to test a new chevy was for us and you. We can't make a silverado fit in our garage and are reworking our options. My better half loves the idea of on star. We have made many non-stop 1300 mile trips. It seems nowadays our interdependent society leaves a lot to be desired and we find we have to do things ourselves.

    A few years ago my father-in-law sold his 30 year old chevy truck. Stupid me thought it had no value. Guys lined up to buy it and a guy from Colorado, first in line got it. The sad look on the faces of the also rans will never leave me.

    If you truly need reliabilty and believe the chevy truck is that bad, why not buy an old body on frame, an old iron block, new carburetor etc you get the message. If no new car line is reliable like everyone says then depend on yourself.
  • tired_old_davetired_old_dave Member Posts: 710
    What one says is just as important as what one doesn't say. We were told to use 0w40 and yet you keep telling us the engine manufacturer said to use 5w40 and 10w40. Reconcile that. Who's 10w40 diesel oil do you use?

    Last year I talked about mechantibilty - I was hoping those of us who wanted out would have a champion to let dcx bite the bullet and not us. Nobody took my bait and I am not an attorney or connected.

    Our Liberty CRD had to be towed to the dealer yesterday. The engine stalled in stop and go traffic and could not be re-started. It cranked over but would not fire. I had my wife prime the fuel system but that didn't work. Last week we had the engine light come on a few times and go off. Called the dealer and schedual for next week but it didn't make it now.... did... it. Road side assistance was there within 15 minutes. Now we have a loaner "car"

    I'll let ya'll know what they found that would have killed it when we get it back.
  • smokinclattersmokinclatter Member Posts: 40
    I have been looking at the Hummer H3. If you go to their Edmunds Forum you see very few posts, some problems, but mostly bragging on their vehicle. The lack of posts is what is most apealling. No diesel available yet....but it has a big 5 cylinder.
    But I have temporarily lost faith in my 37 years of new car buying expierience......so who knows?
  • siberiasiberia Member Posts: 520
    Remember when all we used to worry about was water in the fuel, a little brake chatter in the morning backing out of the driveway and cheesy tires. Those were the days, weren't they? :)

    One of the reasons I bought a CRD was diesel dependability (Ha!). I have never owned a vehicle with the potential to quit so many ways - fuel system, fuel, electronics, over heating, transmission,... If you are not a pretty good shade-tree mechanic and you are thinking about buying a CRD, run away!!

    I really like the vehicle, it has exceeded my expectations in every way and I am going to stick with it, mainly because I can do every thing it's going to need in my reasonably equipped garage, except for the computer flash BS. That does not mean that I want to work on it. I guess I'm going to have to buy a tow bar or tow dolly, someday.:shades:
  • kphoustonkphouston Member Posts: 15
    From the sounds of what I am reading we have enough of a war with the crd's. I had not even heard crd's until a week before we bought ours. I wished I had done a little more invetigating on them. OK alot more. The wife loved the looks and the $50. fill ups compared to the $90 for the Expedition. We don't tow anything with it and she only uses it to go back and forth to work so I am holding out hope for no major issues.
  • ecrdecrd Member Posts: 5
    I have been searching all the posts but it has been difficult to figure out what the solution is to the transmission problem. Could someone point me to a post that discusses the solution, or if it doesn't exist, simply state what the solution is? THANKS
  • arvmanarvman Member Posts: 95
    Quite a few posts back siberia gave me the numbers on the T.S.B.'S regarding tranny and e.c.m. issues.
    18-009-06 t.c.m.
    18-018-05 e.c.m.
    Mine's working fine so far so I don't want to fix it if it's not broken.Just feels like I'm sittin on a time bomb.Problem is I like this vehicle,good luck,ecrd...
  • siberiasiberia Member Posts: 520
    I think the post you are looking for, Ecrd, is #6907 by Ggrimm01. The solution is to replace the transmission pump with a redesigned pump and what ever parts got damaged.

    The TSB(s) that Arvman mentioned was for "T-conv improvement and durability." My transmission has not failed, yet. I don't know if the TSB will save it or not, but it acts considerably better. The problem is that my tranny did some clunking and grabbing before the TSB was applied. My guess is that the TSB has delayed the inevitable.
  • zachinmizachinmi Member Posts: 228
    Sure is depressing reading the posts since last night. So many problems and negative views. My CRD has had all the current TSBs but the transmission still clunks a fair bit. Again, I haven't had any problems so far, but I am wondering more and more about this vehicle. I wonder if DCX pulled the plug two months ago - a bit early - to limit the number of warranty claims they have to deal with. This seems to be a good reliable engine/tranny in the Euro market but they screwed something up for US purposes.

    I am reading all these and wondering at what point we need to organize a petition to DCX to either fix our CRDs or buy them back at a fair price. This would not be totally unprecedented.
  • farmer52farmer52 Member Posts: 61
    At this moment, I really like my 03/06 CRD. I have about 7300 trouble free miles (fingers crossed). I like the way it handles/rides, the low end torque, and the fuel mileage (28+ highway). Although I drive it like I have an egg under my foot and I have not towed a trailer yet. I do wish it was several inches longer behind the rear seat and Jeep would relocate the spare tire. I bought a "third" party bumper-to-bumper extended warranty ($700)(3yrs/100K miles). I just hope I can make it to the third year and 70K+ miles then I will consider trading for another vehicle. Best of luck to all of us with our CRDs as we will need all the luck we can get. :)

    Perhaps DCX will consider giving us fair market value plus a $5000 bonus. The only DCX products that I like are the Dakota (V8 w/manual tranny) and the Caliber. No Hemi powered vehicles do it for me. A HEMI is not a HEMI unless it is a 426 cu in with 2-4bbl carbs. :shades:
  • tidestertidester Member Posts: 10,059
    A HEMI is not a HEMI unless it is a 426 cu in with 2-4bbl carbs.

    Tell that to the SRT-8 owners with their puny 6.1 Liter (372 in3) hemis! ;)

    tidester, host
  • winter2winter2 Member Posts: 1,801
    The old 426 dual quad hemi engines were conservatively rated at either 425 to 435 HP. It was not uncommon to dyno one of these engines and see in excess of 625 to 650 HP stock from the factory. I have personally seen that.

    I have also had the privilege to be a passenger in a late 60's Super Bee with a hemi. Zero to sixty was frighteningly fast. Sixty to 120 was even faster and more frightening. I have yet to to try a new SRT-8, but I do not think it can duplicate the hemi of old when it comes to that feat.
  • winter2winter2 Member Posts: 1,801
    After reading some of the posts related to this issue, I felt I had to say something.

    For those of you with problems that just will not seem to quit, I feel for all of you. I have been there and done that at least once or twice in my life. It is very unsettling at best. In some cases you truly have a lemon, in other cases, incompetent techs.

    For those of us with reasonably reliable equipment, I guess we are lucky or our turn is yet to come.

    But on the other hand, some of the other major brands are not faring so well either. Toyota has had to recall in excess of one million vehicles for various problems including some that are downright dangerous, like steering that falls apart or sticking gas pedals, or serious software problems that cause a car to totally stop functioning (Prius HSD models). Toyota had a sludging problem with some of their engines in the late 90's to the early 2000's that they refused to acknowledge. A CCV redesign fixed the issue. VW had a similar problem. Honda has had problems with transfer cases that disintegrate in their Pilot.

    What I have just written are just a few examples and I am sure I could fill many posts with dozens more. My point is that there are several solutions to these problems.

    1. Get them fixed by finding a competent dealer.
    2. If your state has a Lemon Law, use it.
    3. Find good non-DC mechanic who can fix these issues, and see if DC will refund you all or some of the repair.
    4. Realize that no one makes a perfect vehicle and that you will have failures. It just seems worse when it is your own. Your faith in the vehicle and the company gets slammed when you experience repetitive failures of the same type and you have no real resolution.
    5. Just get rid of the bloody thing and hope what you replace it with is better.

    Realize as emissions controls grow tighter for all vehicles, their complexity will increase and so will the number of failures.

    the nineteen sixty three hemi was for hundred twenty five horsepower to the rear wheels and they wer fast i had a nineteen sixty three chevy three forty eight three hundred fifty horse power the hemi would eat it alive
  • vtdogvtdog Member Posts: 163
    I have not been on this site for a while and it seems that it has turned very ugly against the crd. The change seems to be led by a few who have had problems with their car. To them I say: sorry. My advice is fix it, trade it, sell it, lemon law it, but just don't whine about it.

    There are many others who have had little or no problems with the car. In my personal case I have just under 30k miles on a '05 sport. It has been in the shop exactly ONCE for repair other than normal maint: EGR (not a surprise). I regularly get the mpg listed by EPA and have made no mods other than to get rid of the lousy OEM tires. It has started in all weather (-12F being the coldest) and blows cold A/C on the hottest days. I use it for a daily driver and for recreation. I don't rock climb, but do take it on dirt trails. In short, it has at least met minimum expectations, if not passed them in many categories. Sure, I worry about the noted problems, but I don't lose sleep over it. It is just a car, for Gods sake. As Bart would say: "don't have a cow, man!".

    There was a poll on another jeep site which asked if you would buy the crd again. I don't remember the exact figures but only about 5-8% said they would not. It probably isn't statistically valid, but it does give at least a snapshot of owner feelings. That being the case, a 90%+ rebuy seems to be an impressive number to me.
  • goodcrdgoodcrd Member Posts: 253
    What classifies an engine as a "HEMI"? Is it just the Shape of the top of the combustion chamber of the cylinder head? Or do they also change the way the air flows into the intake? Maybe both. I know the answer. Do you? And how many of the engines which mopar uses can be classified as hemis?
    My first car was a Fury III with a 440 with the six pack and 727 trans. It had the Dana rear. Couldn't make it past a gas station to save my life. It was a beast!! But I love my CRD. I now have 30,000 miles plus and it runs great. No complaints here. Wish fuel was still below 75 cents a gallon when I had the 1970 Fury but when we are kids we don't take care of cars. We just run them and enjoy them. Torque is KING!! Horse power was for the little engines that didn't have the torque. I love my CRD!
  • tidestertidester Member Posts: 10,059
    Zero to sixty was frighteningly fast.

    Really! A lot of muscle car owners had their attitudes adjusted - much to their dismay.

    tidester, host
  • tidestertidester Member Posts: 10,059
    My understanding that it is both the geometry and air flow. I'll leave it to the experts here to fill in the details.

    tidester, host
  • goodcrdgoodcrd Member Posts: 253
    Your exactly correct! The neon's 2.0 would be considered a hemi if it was just the shape of the combustion chamber of the cylinder head. But it's old tech. Makes a great marketing tool.
  • steverstever Guest Posts: 52,454
    "Hemi engine" is a trademark of DC, but BMWs, Peugeots, Toyota, Porsche and Mitsubishi have all sold variations of "hemi" engines. Wikipedia says that the modern DC engines aren't even true hemi's since they have a "polyspherical combustion chamber" instead of hemispherical.
  • goodcrdgoodcrd Member Posts: 253
    Hearing about the problems posted by the relatively few except for the EGR failures, I'd like to here from the CRD owners with no problems other the EGR issues. The Egr issue should be calming down about now. The few trans and engine defects I'm hearing sound like common minor defects which plague every model. Yes even Honda and Toyota. If you read the complaints in detail the engine problems are varied and few. The trans issue of the torque converter and pump is not wide spread enough to effect more the 3 to 5 percent of the CRD owners. 20% is considered a model defect. Also most dealers send trans work out to specialty shops so their is an added delay in transferring the vehicle. The trans issue will resolve itself over the next year when the techs get familiar with this trans. As I have stated before. I love my CRD. I'm not worried about the trans. If I need to get it rebuilt I know the price is going to be between $1500 and $2500 that will be after 70,000 miles. It is Cheaper to put the money in the bank and wait then to buy one of those overprice extended warranties. They always make a profit on this type of insurance. As for myself I'll pull my trans myself take it to a good trans shop and have them either overhaul it or swap it with one they already rebuilt. I used to rebuild them myself but I find it easier to just take the unit in and get the warranty they provide with the rebuild. Don't scare yourself into losing money. If you can't get yours fixed or fix it yourself, yes you have to consider "your" best interest. But don't just bail out on someone else's problems. I'm sure about the EGR valve issue with the surging and bucking is fuel related. The trans issue about the pump not suppling enough volume. I have my doubts. The changing of the filters and examining the material found in the filter and the pan would always be my first step after checking the pressures. There are a number of things which can deep six a trans. And it is not uncommon for new vehicles to have trans issues in the first 30,000 miles. Most trans which have something wrong from the factory will show up with the first 20,000 miles if you make 40,000 miles or more trouble free than most likely you won't have a problem. What I'm trying to say is don't let fear and not understanding a problem lead you into giving your hard earned money away.

    Gee, I just had a Sally Fields moment (of course, I'm driving the Ford Explorer folks nuts today with my no tranny fluid maintenance rant :shades: ).

    A polyspherical discussion; who would have guessed. I miss Dusty hanging out in SUVs; we need to pry him loose from Pickups.

    Last week JD Power predicted that the current ~3.2 market share for diesel cars and trucks will go to 10% by 2015. (link) That seems a bit low and a bit of a long time to get there. Dropping the Liberty CRD for a year doesn't help any I suppose.

    Where did the ford Explorer stuff come from. That model is junk, pure and simple. From head gaskets to dropping valves to you name it. If some CRD owners with problems want to feel better just go to one of the problem and solution forums for the Explorer. Years ago I read somewhere what dusty posted. There are different ways of getting power out of engines. I find Ford V8's breath the best. Chevy V8's are very tolerant to abuse and Mopar loves V8 torque monsters. Back in 70's Mopar ruled the drag stripes. I love Corvettes. They are just beautiful. A 2006 red convertable with a tan top and tan leather interior. Auto for cruising the shore down by Cape May.
  • tidestertidester Member Posts: 10,059
    I love Corvettes.

    So would you rather be cruising in a Corvette or doing some serious offroading in your Liberty CRD?

    Can the ERG be eliminated in the CRD? Can it be bypassed? Will the computer have to be re-calabrated.
  • gob2gob2 Member Posts: 3
    This gloom and doom is depressing. Does anyone know of code
    readers for our CRD that reads all the codes and writes things
    like tire size changes? I talked with Mr Jay Horak with Autoenginuity and he said they could write code if they had a
    vehicle to read. Are any members in the Mesa Arizona region willing to explore this?
  • rnaborsrnabors Member Posts: 25
    I am one of the very happy CRD owners. Mine is a 3/05 build and I have 12000 miles on it.
    I have added mud guards, a skid plate under the transmission, Bridgestone Alenza's 235x16, rear air deflector, and a Garmin GPS.
    I have followed the maintenance called for in the owners manual, the oil called for in the manual, the work is done by my local Jeep dealer, and by the way, the service manager of the dealership drives a CRD.
    I have not tinkered with it, added anything to the oil or fuel, cleaned out any hoses etc.
    I have had zero problems other than occasional noisy rear brakes in the morning.
    Interestingly enough I have recently talked to two other CRD owners other than the service manager (the only ones I have talked to) that had the same good experience with their 05 CRD's.
    I feel bad for the people that have experienced problems and hope they get corrected.
    I would also be careful in assuming all CRD's have problems---they don't.

  • winter2winter2 Member Posts: 1,801
    A "hemi" head engine, okay let me see if I can explain it to you.

    Take a ball, slice it in half. Take one of the halves and scoop it out. That is the shape of the combustion chamber as it lives in the head. The spark plug is located centrally and the valves are on either side of it.

    In the days of old, let us say from the mid-fifties to present, there were many. Their displacements were, in cubic inches, 303, 331, 354, 392, and 426. The 392 was one of the stoutest engines ever built and was nearly impossible to destroy.

    DC still makes hemis like the old ones but they are only available through Direct Connection, DC performance parts division. None of them are cheap. They range in size from the 426 to 572 cubic inches in displacement. The 426 comes in several flavors from ones that will run on pump gas to others that are designed to run on exotic fuels. The 572 is usually reserved for dragsters and when properly setup is good for more than 2500 HP and about 3000 lb-ft or more of torque.

    The new hemi engines have semi hemi heads. They have some or most of the characteristics of the old hemis but it would take forever to explain. The new heads are easier and cheaper to make. The old, original hemi was more expensive and harder to build because you had to splay the valves to accomodate the shape of the combustion chamber.
  • winter2winter2 Member Posts: 1,801
    Vtdog,

    I agree with your comments. When it is your car and the repairs are not being done properly, or at all and you are being given the run around, it really inflames the situation you are experiencing.

    I just broke 11K miles and have been generally pleased with my CRD. It does what it is suppose to do and on the highway exceeds EPA values.

    I have been using S15 diesel for the past several tanks and the little guy runs better than ever. Yesterday I sniffed the exhaust fumes. I do this from time to time to make sure I do not have a blown head gasket or I am burning any oil. Since my CRD has been on S15, the exhaust is nearly odorless. It has less odor than the exhaust from my wife's 1998 Chrysler Concorde.
  • vtdogvtdog Member Posts: 163
    S-15? Is that 15% biod?
  • winter2winter2 Member Posts: 1,801
    No. S15 is another way of saying ULSD. It denotes the amount of sulfur in the fuel, 15 ppm. S500 is also known as LSD, low sulfur diesel.

    There is no biodiesel in it.
  • ampmanampman Member Posts: 6
    I also like my CRD. I had the EGR replaced and the updated TSB's completed. I ahve not had any other issues and have had no tranny shutter even when the cruise control is locked at 55mph and accending a slight upgrade of an overpass. I have gotten 34 mpg cruising at 72mph @2000rpm highway and a steady 22mpg city. The only thing that I don't like is the spotting of the seats with any type of water ie. rain or sweat. I've been using Shell 5W40 synthetic,B5 Bio and a splash of Stanadyne Performance for cetane enhancement and added lubricity. The CAC hoses have minimal oil trails and while off for inspection I wiped out the EGR throttle body. Next week I will begin using ULSD blended at B10, hopefully this will eliminate any future EGR issues. Overall its been a vehicle that has lived up to my expectations and look foward to good long trip up through the Blue Ridge Parkway.

    I have been having a steady decrease in my fuel economy in my 2006 CRD. I have been very happy with my Jeep other than this issue. I changed the oil at 1500 miles and use Rotella 5-40. I have checked my inter cooler hose and there is a very slight amount of oil residue present. I had to take my Jeep to the dealer for a recall for one of the modules for the dome lights. I requested my vehicle be checked to try to determine the loss of fuel economy. When I first purchased my Jeep we checked and we were getting 26 miles to the gallon. Now it has dropped down to 20 miles to the gallon. It does not matter if is is city or highway driving. I have tried all different types of fuel. I always use the directed amount of Stanadyne Performance formula. I don't have the trip computer. I refill the same way each time. Any ideas any one? Thanks in advance for your help.

    The Technician at the Dealership had a brilliant reason for the drop in fuel economy. I had my GoodYear SR-A highway tread tire changed at 100 miles to General All Terrain. The Tires are the specified size. I asked " so, I have lost 6 miles per gallon because of a different tread design??? He said "Yes", Hmmmm well,I did initially get 26 MPG even with these evil tires. He got quiet and walked away.
    There was an update for my Jeep that was performed to update the Torque converter lock up points.

    You might be heading for EGR failure or else your trans may not be locking up properly giving you more slippage or it could be in the wrong gear for whatever given speed you are at.

    As to the tires, the more aggressive the tread design the more friction you end up with. If they are the same size as stock, you might lose some FE but very little.

    How many miles do you have on it at this point?

    Well, after much thought and reading, I decided to try the CRD. I already am used to the test mule issue as I had one of the first Hemi 03 Dodge trucks. I won't even get into its issues as there is probably another forum out there for them and this isn't the place. At least I gave it back to them and got a good trade price out of it.
    So far the CRD is going good. The first tank through netted me 20mpg even- hand calculated.The computer showed as high as 26.8 avg. This is kind of country- city driving, go a few miles at 55 -stop and go again type of thing. Much better than what the Hemi delivered.
    Dealer called tonight on a recall for the battery- drain issue. Said thats all he has on it. I'm wondering if the trans parts have been updated on these last ones built- anybody have any idea? My build date is Feb - 06. It goes in Wed to get re-booted for the Battery. Is there anything else I should check on while they have it plugged in?

    So whinning about the whinning is OK ? Just not the lack of qualified techs, back ordered parts, multi week stays in the service dept etc.

    I agree, although it showed no fault codes yet, The EGR is what I also suspect from what I have read here. I guess we will have to wait for the fault code to appear. It seems to be locking up cosistantly. It's about 1700@ 60 mph.

    I agree with you about the tires, At worst I figured I could loose 1/2 to 1/4 MPG. They are the exact size as stock.

    I have right at 5000 miles now.

    Thank You!
