#124 of 133 Am I that unusual? by jerrydock Jun 29, 2008 (11:07 am)
I bought a used 2005 Chevy 2500HD 4x4 with the Duramax and haven't had any problems. Are there others who have had no issues?

Replying to: rsorling (Aug 26, 2008 3:33 pm) I have a 2007 3500 crew cab and pull a fifth wheel that weighs just over 13,000 lbs. Next time you hear this look at the engine temp if it is just past 210 then it's the clutch fan kicking in not the turbo, mine it so load you can't hear the radio. I'm betting that's what it is.

#130 of 133 2004 GMC2500 Duramax Electrical Problems by slyjoe Oct 13, 2008 (6:10 am)
I've owned this truck since new and it has just under 60k miles now. I am on my third set of batteries. Does that seem excessive? I live in Las Vegas where the weather is often over 100 degrees. I haven't replaced them in over a year and haven't had any problems. Just yesterday a problem arose. The clock on the radio goes to 12:00 as if the truck has/had a dead battery. All the presets are still there, but ther clock reverts back to 12:00. The truck turns over, although a bit sluggish. Anyone have/had the same or similar problem? Thanks..Jarrett

I have a 2007 gmc duramax, the problem i,m having is the dash lights dont all work. the dealer replaced the radio because some of those lights went out at about 34000k miles. since then i have had more problems with other lights, like only part of the speedometer lights up, only half of the climate control lights work. now i have some interference in the front speakers. when the seat belt reminder chimes i can hear it in the front speakers. please any help would be great. aj
#132 of 133 6.6litre duramax diesel 2500HD 4x4 LTZ crew cab by dieselrookie3 Nov 09, 2008 (4:39 pm)
I just bought a travel trailer(5500 lbs dry weight- 7000 all in?)and need a long term vehicle to tow it. I've test driven the above vehicle and find it has LOTS of power. The question is...fuel economy. How can I get the best fuel economy with this truck? After market chip? Do I need the 6.6 or will the 6.0 litre be sufficient. Which of the 2 would you pick? Any specific problems with either one? The blog entries really don't describe any with the 08 models. Also, I am Canadian. Do you suggest I buy State side and pay the dollar difference? The only taxes I have to pay is the standard 7%pst + 5%gst. Just trying to be wise in my decision over the long run. thxs

well my 01 6.6 duramax with only 75000 mi had to have head gaskets put on at $4,700 i talked to the dealer ship and told them that i heard about the the problem with the gaskets on that and made like this is the first time they ever heard of it i got this truck when my son inlaw past away it was his baby the dealer ship also said if i was the first owner they might cover part of the cost anyone else as happy with G.M as me.
