Hi all. I’ve owned a truck for many years but recently bought my first GMC. I was at a dodge dealership looking at a new Ram when I noticed a GMC on their lot. It really caught my eye and after checking it out I took it home. It’s a 2020 Sierra 1500 and was traded in with only 7k miles. Seems some lady had it and wanted a jeep instead. Lucky me!  I gotta say this truck is smooth and quiet. I already love it. 
 

so, what are the important things to know for GMC trucks?

Congrats on the beautiful truck. This past year, I got my step-dad to convert from a F150 to a white GMC Sierra SLT. After driving it, he couldn't believe how it rode and drove. Was blown away. A year later he still states how he can't believe how much better the GMC is than the Ford. I had been telling him this for the previous 8 years, but he always just went and got another F150.  Hopefully the truck treats you wonderfully like mine and his has to us.

DFM is a pain in the dick but other than that there isn't a whole lot.

If you got the sliding glass rear window it can leak.

GMC is by far the nicest looking half ton, imo

I have had MANY trucks. This new GMC platform is about the best I have owned. Great truck. There can be minor things but overall they are a great truck. Enjoy.

It seems the 2019-2021 GM trucks (Sierra and Silverado), are plagued by two major problems. The first is lifter failure which may be attributed to DFM (dynamic fuel management), the lifters, or a combination of both. The second is a leaking rear window. If you search the forum, you’ll find information about both problems.

Leaking rear window is a "when" and not an "if".  Lifters seem hit or miss.  Lots on the plus side though.  Ride, mileage, power (depends on engine), etc.  Pretty happy with mine other than leaking back window which was hopefully fixed earlier this week.

had 4 T1 GM trucks and 2 with rear sliding windows.......no issues on any of them, my first had lil clunk on 8 spd but not horrible, second 8spd was flawless........ dont live in rain and snow so only car washes

 

think GMC was better looking and slightly nicer finish overall, but 4 trucks 4 good results for as long as i kept them......

      Tire psi

      By jgaudet99 · Posted

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.
