What do I need to be aware of buying?

[mxgirl75]

I've been looking at the 2020, still might end up with a 2017 or 2018 3500....

What do I need to be aware of?

I have friend who is involved with extended service contracts and he says the thing he sees is the high pressure fuel injection pump?

He also states that GM seems to be the least problematic...

17 and up L5P do not have the CP4 issue olders trucks had.

ive been looking around my 2020 for possible problematic areas and have not found much other than doing my own PCV re-route to keep the intake clean.

if you can swing the 2020 over the older models, i would do it in a heartbeat for the 10 speed and larger cooling stack. massive difference between them and towing heavy

How much can your 2020 2500 tow?

 

[Chevy1925]

18,500lbs. My toyhauler is 15k loaded, towed with both my 02 and 20

Only giving insight for 2019 L5P. It’s a Denali 3500 and gets used for hauling the 3 horse trailer with living quarters. After 20k miles no issues and just can’t find anything I don’t like about it. Neither can the owner (wife). We got it with the “puck” system for towing so it’s easy to swap in the ball for gooseneck. With 3 horses and loaded I believe she said it weighed around 16k lbs. when she makes her runs for horse shows she says she has to set speed limit warning on cause the truck still pulls it effortlessly and doesn’t realize how fast she gets moving down Highway.

2020 should be a great pick too though. Anything GM makes in diesel truck world

 

[mxgirl75]

Thanks everyone for their input!! I really appreciate it...

Going to take my piece of crap over to one GMC dealer who has a 3500HD Sierra with technology package on it... $65.329 we will see, they need to tell me the trade in value, also in detail and writing the warranty and lifetime powertrain coverage...

 

[KyleC4]

And make sure what they offer is through the dealership and what’s through the manufacturer. Only saying that because you mentioned lifetime power train coverage. We have a dealer out here that’s doing 10yr 200k powertrain coverage but vehicle must be service at dealer at their recommended intervals as well as that coverage is only supported there. Meaning if you were to go somewhere else when your GM warranty has expired they would not honor that warranty as it’s through dealer.

Thank you, yes I am going to make them tell me what is involved with the lifetime stuff....

Seems there are issues owning a diesel

I posted on my FB page and got hammered by several people about owning a diesel...

I have read about a stock diesel pulling a reasonably heavy load up a hill... I could potentially be pulling a 15,000 - 17,000 pound toy hauler up some pretty big hills on I84 from Oregon to Idaho for races in Boise...

Some people have said with the high compression fuel injection it can put garbage into the pump and destroy the engine...

I am not wanting a gas engine as they do not have what it takes to.pull that kind of load...

 

[mxgirl75]

Just the exhaust emissions systems alone.OMG.Scared...We lease a couple of brand new big rigs with this stuff.Constant issues...Lights flashing."exhaust filter" "re gen needed asap" "stop now" ...Do your homework.Check the forums or groups.

Diesel make sure they cover the fuel system that's the pump high pressure fuel rail injectors big ticket item if or when they go bad.
That goes with the EGR cooler oil cooler, DEF, Turbo. system.
Some warranty will cover just the motor.


These are two of the comments I got

 

[Chevy1925]

Why ask us these questions if you are just going to post elsewhere and then question what we have stated because some morons on there have no idea how the 17-20 trucks operate?

either you trust us who have well more wealth of information as well as some of the top performance racers and builders on this site along with top notch mechanics or you believe these idiots who try to compare a big rig operating system to these trucks or this other idiot who doesnt understand how a warranty works or the fact there was a high pressure pump redesign, different turbo used and so on since the 11-16 trucks.

Im in a mood today and frankly, FB warriors f**king piss me off because everyone is a god damn expert with no experience in the trucks we are talking about. as you can tell, this site very much specializes in these trucks

You really need to spend your time researching these trucks via either here or google on how the engine works, what the newer trucks use, the advances in filtering tech for the exhaust and so on. i understand you are new to this but you are extremely green as well if those facebook comments freak you out. you have ALOT of searching and reading to do

[Bdsankey]

I guess third?

The 17+ trucks are not able to be compared to any other duramax produced (01-16). As James said, Facebook warriors do not know what they're talking about. Sure, there are some knowledgeable people on the Facebook groups but their knowledge is drowned out by 10 million posts of bullsh*t from idiots.

 

[mxgirl75]

Well thanks for your input everyone!!!!

I am hoping to head over and see what they will give me for the piece of crap...


First I have to go deal with a bank issue.....

 

[trapman01]

The semi trucks seem to have the most problems with egr coolers and exhaust treatment devices. We replace them a lot. The emission system has separate warrantees for the semi trucks also.
The pickup truck market is nowhere near as bad.
I have had many of the duramaxes (04.5, 06, 08, 11, 14, 16, and now a 19)
And have been very happy with them and only had minor problems. They have treated me much better than the fleet of class A trucks at work.
I tow an 18,000 lb fifth wheel toy hauler.

Good luck

My experience, which is nowhere close to some other here, is that the gas trucks tend to nickel and dime you over the course of ownership while the diesel trucks tend to go a long time with nothing but when they need it it cost a lot.

Some complain about the oil changes costing a more but the intervals are further apart too

From what I have seen, and delt with myself. Gas trucks have coil packs that go out it seems on every make and model. Plugs, wires. Several with evap issues. Oxygen sensor problems. Throttle valves, distributors, fuel pumps, etc.

Most of these don't cost more then a few hundred. Most far less. But it seems they happen more often but because of the lower cost people are less shocked and pay out without hesitation.

For the Duramax, 11-16 has the rare but possible fuel pump issue that can take out injectors with it. probably no more then a few percent of the trucks will have this but can set you back thousands. The LB7 had injectors that when bad prematurely. Again could be several thousand dollars. When the emissions where tighten up and EGRs, DPFs and urea injection was implemented, it had growing pains. Most of that has matured to the point where it isn't much of a concern anymore. Just remember, when emission controls first went on gas rigs people hated them and routinely gutted cats or removed them. Now most don't even think twice about it. Diesel is not far behind

When it comes to the rest of the truck. Most everything else is the same. Steering, wheel bearings, suspension, electronics, etc

I say to each their own. I have no need for a diesel, don't pull enough to justify it. But I wouldn't have anything else

Merged your two threads, and moved them to Smoke Signals....thats where all the "buying and selling" threads seem to go.

Good luck in your search, and dont listen to the FB idiocy.
