High milage registry

How many miles does everybody have on and what issues have you had?

40K and only issue for me was the steering shaft that was finally resolved some time back. Oh, now my tranny won't hold....but that's my fault. Hello Suncoast!!

I have an 01 I bought new that has 140,000. I have doubled up chips on it at the dragstrip and the tranny is a little weak. I have had the injectors changed and I think the fuel pump may be weak. It pulls 26,000 pounds gross on a regular basis. I have an 2004, but I can't get it to get as good of fuel mileage.

This is a common problem. My 03 started doing it at approx 20kmiles. The TSB is as follows:

"Clunking Noise Under Hood and Can Be Felt In the Steering Wheel (Lubricate Intermediate Steering Shaft Assembly) #00-02-35-003B - (01/24/2003)"

Search the 2500HD/3500 Trucks & Drivetrain Forum for "steering clunk" for more info.


So far my 03 with 26kmiles has had the following problems fixed under warranty.

- Poor A/C Performance TSB - reprogram, new pressure switch and recharge.
- "Service 4WD Drive" Error, No 4WD - Replaced encoder motor assy in Transfer case.
- Intermediate Steering Shaft Clunk - grease shaft TSB
- Leaking Rear Axel seal- Replaced seal and e-brake shoes.

I consider the problems minor

tbrowne,
Far statement. I think that's the sort of stuff everbody and myself would like to know.

92,000 miles on my 01. Injector pump at 85,000 and no other problems.I get 20 mpg on a regular basis.

I have used AMSOIL from the beginning and change the oil filter every 6,000 and the oil and the fuel filter every 12,000. Oil consumption is negligible. Fuel mileage is 16 mpg in town, 18 mpg on the highway and 14 mpg towing 4,000 lb camper. Highway speeds are 80 mph plus towing or not.

I just replace the stock shocks with Bilsteins and added Bridgestone Revo 265X75X16 tires.

This is probably the best vehicle I have owned except a 1977 Buick that went 235,000 miles. The GMC may beat it at the rate it is going now.

IMHO - BB forums, dealer mechanics and diesel garages are good at providing input as to failure trends. However, these sources may not provide a balanced look at the overall picture.

In general, problem trucks appear in BB's and dealer shops. The others are rarely discussed or seen by those who work on them. This can present a biased look at any given issue.

Better data can come from knowing the total number of Duramax truck sales, and compare that to warranty service documentation. GM knows the numbers, but I doubt they'll share.

Just an intuitive guess, but I'd bet that if there was a 33% in-warranty injector failure rate, GM would have already stopped the bleeding.

GM most certainly knows the numbers (and no, they probably won't share). Warranty work of any sort is costly for both GM and the supplier of the part/component in question. GM tracks the warranty complaints of all supplier related components, and if the warranty track record of a supplier is bad enough, GM may not send new business to them in the future.

Every time you take your truck into the dealer for ANY warranty work, somebody gets a check next to their name, be it a supplier or the assembly plant for 'poor' workmanship... but that's another story... ;)

tbrowne - I hear ya. I've not had problems...yet with 55000 miles, but I'm concerned. What is the alternative? Ford has major issues, it's a crap shoot. Dodge now has Cummins with the same injectors the DMax has, AND still does not have an auto transmission. With my 5th wheeler, I need a diesel. I'm getting disgusted with the whole industry.

GM learned an important and valuable lesson with the Stanadyne DS4 electronic fuel injection pump. That being to better test and evaluate a new technology before committing to production, and to correct a design and/or manufacturing flaw before it damages a reputation or the bottom line.

No engine in the history of GM has received a more thorough testing and evaluation phase than the Duramax 6600. Engines were tested more than two years before going into production, and fleets of Duramax test trucks were placed in service in Alaska in the winter and the Southwest in the summer, all to illuminate any design or engineering flaws that would impact warranty service and/or customer concerns before going into production.

I personally drove two Duramax powered trucks a full year before the first one was sold to the public.

Now, manufacturing defects crop up from time to time, and assembly errors occur occasionally, but I believe the basic design is sound.

MP How does one get on that list?
