Replying to: boilermaker2 (Jan 05, 2007 1:50 pm) I am pretty much thinking if this CRD gives any more recalls or things needing warranty repair between now and when the 2008 Liberty's come out, I will take the Lemon Law all the way no matter what. I like the CRD, but I am not needing a fulltime hobby. How is your CRD doing now? Farout

Do you understand which group I'm pointing to? In Europe when you buy a local common rail, you almost know 'by contract' that you will face problems.

Replying to: boilermaker2 (Jan 04, 2007 12:34 pm) Let me explain the "American greed and laziness" to you and others here. While I was in FL, I had an oil change done on my CRD. I provided the oil and filter and told the dealer that I expected to see one-half quart of oil on the back seat floor when they were done. Where do you think that one-half quart ended up? Yup, in the crankcase where it did not belong. I made them drain the oil and do it right. Also had the two recalls, ball joint and F37 done in FL. Both dealers tried to sell me services I did not need namely fuel filter (due  25K) and differential and transfer case service. In either case, the latter service cost about $350. I am taking it to a local independent shop here in MD who will do the differentials and transfer case service for $160 including the lubricants (all synthetic). I will do the fuel filter myself. Farout, you may regret being a guinea pig like some others in this and other forums. You are entitled to feel that way. I however do not. Yes, the recalls and the few other repairs have been an inconvience., but they cost me nothing except a little bit of time. If the CRD is/was an experiment and I am happy to be part of it. I feel that I am helping to pave the way for diesel power to make a come back in this country. I do not feel deceived or duped. I took the risk just like the rest of the CRD buyers in this forum and elsewhere. Nobody put a gun to my head and said you have to buy a CRD and I am sure that this the case for everyone else who owns a CRD. As to the EGR valve, I chalk that up to fuel and design. Boiler, you stated that you used 51 cetane ULSD when available. What percentage of the time did you get it? Domestic 51 cetane ULSD is not EU quality 51 cetane ULSD, plain and simple. The EU spec for diesel is quite different than the domestic spec. EGR failures in our CRDs is a design problem (hardware and software) exacerbated by the use of domestic LSD (S500) fuel with a low cetane rating.

Replying to: caribou1 (Jan 10, 2007 1:41 am) Looks like you are pointing to the Bosch people. I heard at one point that their reputation was quite good. Have their products and their quality taken that much of a turn for the bad? If so, that is a shame. I had a 1993 Dodge truck with Bosch injectors and injection controller in it. Had to replace six of eight injectors by 80K miles for leaking fuel. Other than that, it worked well. In Europe when you buy a local common rail, you almost know 'by contract' that you will face problems. What kind of problems/issues do I have to look forward to?

Replying to: winter2 (Jan 10, 2007 9:25 am) If you were to go back to 1993 Bosch parts, you would again have this beautiful quality. I was in the bar turning industry when american car manufacturers decided to use fuel injection. Bosch specifications for making injectors were very strict. The chosen manufacturers were the richest ones, those that had invested in quality control and modern machines that were built to match these specifications. I live in the heart of the former bar turning industry area, between Chamonix and Geneva. Today every company seeks immediate profit because products change rapidly. It's the same as asking a granny to cook something and comparing to how our kids interpret ate the word 'cooking'. We unfortunately share the same issues, perhaps paying more over here.

Replying to: caribou1 (Jan 11, 2007 9:07 am) This comment is so true. So what kind of issues should I be looking forward to? I can think of a few such as injector failure, leaking injection system, controller failure, sensor problems, etc. What are you seeing or hearing? I would really like to know. Way back in 1993, it was the second year Chrysler had used port injection from Bosch on this particular engine, 5.2 L V-8. In 1992, the system had a lot of problems and miserable reliability. In 1981, my Isuzu diesel car had a Bosch licensed system on it. The distributor pump got a little cranky as it aged and the injectors had to be replaced at 110K miles for internal leaking. What are the Asians using in their diesels. I know Hyundai licenses the 1.5L three cylinder diesel from V.M. Motori, but which injection system do they use?

Replying to: winter2 (Jan 10, 2007 9:06 am) As for taking a risk, I did not believe that DCX would place me at risk when buying this vehicle. I should tell you we bought a 2006 Liberty 3.7 Sport and in almost 9,000 miles there has been not one problem. Most all of our issues with the CRD are related to the engine add on parts, not the block or head. I am not going to justify or except being a risk taker, or "Test Market buyer". No one expects to take sub quality vehicles just to be part of an "experiment" as Dr. Z said in a press conference when he announced the Liberty CRD would not be offered on 2007. I do not think I am being unreasonable, I just want what I was told I was buying. Fair enough I think. Farout |

Replying to: farout (Jan 11, 2007 5:32 pm) As for taking a risk, we do that every time we buy something. For your dealer to tell you that this vehicle is more reliable is probably a half truth. If it was bought in the EU and maintained there, that probably would be the case. Even Toyota is not without significant problems. They just settled a multimillion dollar lawsuit (they lost) to cover complaints of engine sludging in properly maintained engines. Question. If you had been told that the CRD was for testing purposes as it is now known, would have still purchased it? Now for something totally different. Started my CRD this afternoon. The low coolant light came on. Always check to see if there is lots of white smoke when I start it cold. None of that so no head gasket issue. No puddles on the ground and no seepage on any of the cooling system hoses. So what has changed recently? New EGR valve a few weeks ago. Problem(s), two possible. Since the EGR is liquid cooled, it could be leaking internally. If that were the case, I might see some white smoke. Most likely scenario is that when the EGR was replaced, the technician in FL did not purge all of the air from the cooling system properly. Added more coolant (the correct stuff)and a little distilled water. Will watch and if the level again drops, then to the dealer we shall go. I will keep you informed. |

Replying to: farout (Jan 11, 2007 5:32 pm) Something struck me at about 3:00 A.M. this morning concerning the cruise control issue in your CRD. The cruise control and rear brake light switch are an integrated unit as far as I recall. That unit should be adjustable and it may be a bit too close to the brake pedal so that every time you hit a dip or bump, it disengages. The other possibility that came to me was that the return spring for the brake pedal might be a bit weak. Let me know what you think.
