2015 Silverado Duramax?

timswi · Nov 20, 2016

Anyone own one that can give me the good and bad?...Please no Ford/Dodge gas/diesel thing I am well aware..Looking at a High country 2500 HD Duramax...My last diesel was pre current emissions. Yes I will pull with it..

Any honest opinions are welcome before I buy this..6000 miles. Buyers remorse thing with the previous owner, he couldn't afford it I guess. Getting a pretty good deal.

My son has a 2015 3500HD long box crew cab he bought new with 60,000 miles on it now and he's happy with it. Most the miles put on were pulling a 35 ft. trailer with 3 slides 8,500 lbs. gets good fuel mileage considering the size of the truck and trailer. Empty the mileage is double that of my 6 lt. gas.

I have a 2500HD Duramaxx LTZ one step down from the high country. Just turned 100,000mi. About 1/3 of that is with a 24ft box trailer. I'm happy with it over all. There have been a couple of recalls make sure they have been done.

I get 9-11mpg towing depending on terrain and my right foot. Unloaded I get 18-21mpg. Roughly 5000mi per fill up on DEF. I buy it at truck stops rather than in a jug. Much less expensive that way.

I've been religious abut maintenance and that pays off big time. Rotate the tires every 5000mi and they can last as long as 60,000mi. Not bad for a truck over all.

We have a fleet of Dmax trucks at my company. All are crew cab 3500 SRW 4x4. Currently we have north of 50. Some are 2011 and 2015 along with a 2008.

The 2008 and 2015 have all been pretty good. The 2011's not so much.

Back to the 2015's you are asking about. We probably have 25 and only 3 I know of had any real issues. All 3 have had leaking rear main seals. Other than that I remember a wheel bearing and a few other small items.

Just turned 36k trouble free miles on my 2015 2500HD LTZ CCSB, I still LOVE driving it! We average 18mpg but have gotten 22mpg on long highway trips and the DIC actually recorded 25mpg once!

Our last one with a leaking seal got fixed in KY. The tech took the truck out for a test drive and all was fine. A day later the employee it was assigned to got a call from our safety department about excessive speed.

Come to find out the tech ran the truck for a half hour at nearly 100 MPH. All our vehicles have GPS tracking. Needless to say we will not be using that dealer again.
