duramax problems

[MHorne]

Hey fellas i know a lot of you know your stuff about the three differnt makes and was wandering what problems the d-max was having. You see i married into a chevy family and they are glad i didn't buy a ford but say i should have bought the "great and awesome d-max. " they say that the cummins is using old technology and the d-max is the elite now. Rumor has it they are overheating cause of their aluminum heads. Is that true. Give me some trash on those things, i know they have them. Hell he told me not to modify it cause it will cause that "cummins" to have problems. Even a simple chip would cause it to have problems. He says the d-max will handle anything you throw its way. Give me some trash guys, its time i started talking back.

Injector issues, 2 T Stats instead of one ... water pump that requires a degree to figure out how to remove. . T Cases (263?) that seem to take a crap right after your warranty runs out . . I started, someone else continue!!

I own both and love the Cummins and hate the WussaMax. If you own one with the LLY engine it has the worst turbo lag I have ever been around. If the light turns yellow you better hit the brakes because by the time the turbo spools you will be hit from the side by a car coming the other way. They did fix that on the new LLZ motor. I have a bigger complaint about the truck it's self. Doors sag, rattels, speedo problems, fuel pumps quite and I think I have had it in 3 or 4 times for unknown electrical problems ( lights, plugs ect). It has less than 40K on it, did I mention crapy fuel milage, with a small tank? Next...

Well, around 700 hp or so, they start chunking rods out the side of the block, and I think I read that swapping a turbo takes 15+ hours. Also, the motor is made by IZUSU!

and, on top of all that, you have to use A BUNCH of drugs to get them running!



hope this helps

I'm no Duramax fan but Izuzu has their experience building diesels. You know those orange excavators you see everywhere that have HITACHI written on the side. I operate heavy equipment for a living and I am very impressed with the Hitachi/Izuzu combo. Caterpillar is still trying to catch up Oo. The biggest problem with the Chebby is the truck that surrounds the motor.

Isuzu builds some very good diesels, but, they didn't have GM designing them. :-laf





Aluminum heads on cast iron block without enough head bolts to hold it? Yeah, THATS an excellent design.





Injector problems, even worse than the Cummins. I bought an 05 Ram. My cousin and her husband bought a Dmax. I had 15k and they had 5k when they spent 3 days twiddling thumbs 500 miles away from home waiting for all the injectors to be replaced.





Add enough power to a Dmax and it will throw away a couple pistons trying to be like its big brother Cummins. That oughta set the tone for the evening family discussion!! :-laf :-laf

They do seem to be behind the times with their frame (the chevy), but is the body really that bad!!?? They seem to be an ok truck to me. But... . I would never own a truck I can't work on. And on the other hand, I can do most anything to even the newest Dodge/Cummins truck.

>Not enigne/ Trans related, but the darn frame is so low it's ill-advised to use on fire roads or hard to get to places while off road. I think the frame sits some 8"-10" below the body, exposing the parking brake cable.



>The frame on the Chevy/ GMC HD is a "C" notch channel and not fully boxed like a 3rd generation Ram.



> IFS front suspension is weak and inferior in the Heavy Duty segment.



> Ridiculously small brakes hidden by tiny 16" wheels.



> No manual transmission option.



> Anonymous styling, dated.

I work with someone that is a nice guy, but has had his Dmax in the shop alot lately. Seems to be having alot of problems with injectors going bad (one or two at a time) and the dealer is only fixing them when they go bad and wont change the complete set out. It is a recurring problem and he just bought a new 5th wheel trailer and trying to sell his old one. He has 2 trailers and no working truck to move them. . He's not a "Happy Camper" about his Dmax. But Hey, he says my cummins is too noisy...

 

[WUnderwood]

have you ever popped the hood on one of those things? I wouldn't know where to start! :{



one of the main reasons from going to a Powerstroke to a Cummins is the ease of working on the thing!

[Diesel Nut]

I got a budy that blew the turbo to hell in the first 5K miles. truck wasn't 2 weeks old, and stock to boot!

 

[nutter3]

My friend with a Dmax is alsways compaining about the knocking sound he has on his. It is the injectors, but his dealer wont replace them.

He's had some funny electrical issues too.

I sure wouldnt trade my 2000 for his.

 

[CHolman]

I run into a guy with a 2003 D MAX from time to time at the gas pumps and he put a deablo Power Puck and it screwed his truck up. "So he says" it caused his injector's to go bad. Also that his transmission didn't feel right anymore, I said "no" not the might Allison...

 

[Morse]

I'm not a brand loyal kinda guy. . I'm just diesel loyal. . I've had both. . My 2003 dmax was a nice truck. It got 18 mpg the first tank of fuel I ran through it. The ride was nice, and the cloth interior was better quality than the dodge. It also reacts to programmers much better than the cummins. If you want to have an easy 14 second or better truck that doesn't see many heavy loads, you don't mind setting a little lower (unless you lift it), and you don't plan on keeping it forever, I'd go with the dmax. If you plan on eventually doing some really quick times, or truck pulling with your new truck go with the dodge. Also, my dmax ran 13's in the quarter, but when I strapped a 10,000 pound load to it, my 7. 3 powerstroke with a 60 hp chip had way more balls. It was really odd. The cummins pulls a load well. I did like the allison much more than the 48RE. Night and day difference. I did tear the front end out of my dmax as well. . Tie rods and cv joints broke. . That was an expensive pop. . I was in a truck pull at the time. . Sucked real bad. In all, the dodge just feels like a heavier truck that is proven to last a long time. If you want a truck that gets good mileage, is more car like, you don't truck pull, is easy to run low 14's or better, you don't pull heavy loads, go with a dmax. Throw a program and a set of big fancy wheels on it and you're ready to go. .

common now have you really taking a look at that p. o. s it still looks like an 1988 chevy new style, they just round the edges so they think its faster they did they same on the inside so really you just buy a newer p. o. s maybe if they made some BIG changes id look

 

[ACoffel]

I agree with MORSE , if you want a truck to be used in a cars capacity, then get a

Durajunk, but if your looking for something that can pony up to a load and have a

long happy life doing it, then Dodge is the only choice in the light duty truck segment.

While the Dodge does have a few areas in need of improvement, the overall platform

is more conducive to a real trucks generally accepted and intended use. I personally

think IFS is for PANSIES !

I had the Dmax For about 18 months , It was a waist of my time and money. The truck did not perform well at all loaded, and was in the service bay to many times. Don't pull the dmax and allison too heavy or you will have transmission problems and oh by the way the new emiisions on the dmax send oil into the intercooler, watch the hoses on that they are generally lose and if you get any more boost than just normal driving they will blow oil out around the hoses. I had a lot of trouble pulling a 24' prowler camper in 108 degree weather, the clutch fan came on all the time and we started using oil and coolant. Mileage was not good either7. 5mpg at 65-70 mph.

Oh one other thing also and i quote( my dealer sais that these trucks were not made to pull a trailer down the road day in and day out. His suggestion was to go to a one ton)

I have had my cummins for 6 mos now and no problems, power is great and mileage is way better 29' keystone fifth wheel with a 20' stratos bass boat behind that and we are getting 10. 5 - 12 mpg at 65-70 on the highway with great power.

BS, I hate the chevy interiors, most uncomfortable pile of crap if you ask me.



I really dislike chevys due to thier suspension design, its not really that its IFS, but the fact that there is not a sway bar on the front thats worth a damn. they have WAY to much body roll. Yeah a stiffer sway bar would result in a slightly rougher ride, but i like being able to take a corner at 30mph and faster and not feel like I am going to roll over.
