All, I have a 2021 GMC Sierra 2500HD with the 6.6L gas engine and roughly 8K miles. At the end of last week I was on the highway and my CEL came on and I received a message that said "Service Emissions System within 7 days" or something to that effect. I called my dealer right away and they booked me out a little over 2 weeks and now the CEL and message went away. The truck never ran any differently. Everything I find on the web refers to the Duramax and a similar message. I'm still going to have it checked out but 1) any one else have this message on the gas engine and what was the cause, 2) should I be alarmed that I can't get it in sooner, I only put about 100 miles a week and 3) should I be relieved, alarmed or neither that the code went away after running it for a few days (maybe 50-60 miles). Thanks!

Agreed, but I would say only by a couple weeks. I guess do you settle on the color and get it a couple weeks early, or wait it out. Also, TPW is usually assigned within about a week of 3000 code, so do you need to decide now or can you wait for the TPW to be assigned? Earlier this year, your assumption was right, TPW about 4 weeks after assigned and delivery within 4 weeks after that. I haven’t been following it lately.

Is anyone else having still seeing issues with a newer build 2021? I have a 2021 2500 SLE with a build date of mid-March and mine is like a constant road noise rattle from the steering column area. It isn't the clunk that others are talking about but more of a vibration rattle whether turning or going straight down the road, fairly smooth road or potholes I hear it from 5 MPH to about 45-50 MPH. It doesn't go away at 50 but is drowned out by wind/road noise. I looked under the dash and questioned whether it may be the e-brake cable or something else rattling against something else but it sounds higher. I'll try zip tying it out of the way a little to see if that helps, just wondering if anyone else is seeing the same thing.

Yes, the military discount program still exists and it is a fixed amount ($500 I believe) directly from GM corporate, so dealers should honor it either way, but some do not. When people say they did away with the discount, what they mean is that prior to May 1, the military discount was the same as Supplier Discount which is roughly 5-7% off MSRP. Like the previous poster said, by buying on April 30 vs May 1, his discount was $5500 vs $500.

As the previous poster suggested, the discount is now $500. While I understand that you run this risk when ordering the truck and rebates change, generally speaking these discounts have been more predictable. With that said, I would try to leverage your previous discussions with the dealer and try to negotiate a better dealer discount. When I ordered in February, the dealer beat supplier pricing so it is possible, whether they will do it in this market it is hard to say.

This is what I was referring to. The discount still exists but $500 is not as good as the previous discount program.

It looks like the Educator discount is in the same situation. They took away the Build and Price option and only mention the $500 discount. The Supplier discount site however is still showing the Build and Price option and the true discount. Build and Price is not available for 2022 models yet however. Frankly, since this move is across all product lines and models I don’t think it has much to do with demand alone and of all of the programs to cut the military discount just seems like a low blow. If you are going to tout these programs as a PR platform for good corporate stewardship, then you should stand behind them unequivocally.

I would say for this installation, a cheap inline blocking diode would be cheap insurance. Wire it to the console switch side of the T you are installing in order to allow power flow from the console switch but prevent back-feed. I assume that the different LEDs in the bed are all in parallel so the additional 1.7V drop across the blocking diode shouldn’t be an issue.

I guess I’m on the other end of this spectrum. I came from a 2013 1500 LT with All Star pkg and the amount of features now standard on an LT are a huge upgrade. That’s why I was originally looking at the the LT with leather. Due to the leather pkg constraint, I ordered an LTZ. When it became apparent that my order wouldn’t be placed due to constraints I went back to the SLE with added leather. My other option was a Denali but I couldn’t justify $15k for the few features I mentioned above. In the end neither of those are a deal breaker, my previous truck didn’t have blind spot detection but my wife’s SUV does, and with the tow mirrors, I’ve adjusted the lower panel for my blind spot. And memory seats, my wife has driven the truck once in the month we have had it, for $15k I can adjust my seat once a month. But again, I went into this looking to buy an LT and that is roughly where I ended up in the end.

I’m also surprised by the leather package since that was also on constraint since the beginning of the year. I started looking at an LT with leather, then ordered an LTZ and ultimately ended up with a GMC SLE with added leather. The sport package gets you the same LED lights as the LTZ. The normal LT lights say LED but only the DRL are LED. The only features I feel I’m missing out on are blind spot detection and memory seats. The all star package should include safety 1 package and memory seats is only because I’m 6’4” and my wife is 5’2”.

Based on your post I assume you would qualify for the Military Discount. If you could find a dealer currently accepting it that may be your best bet for any discount. If my memory serves me correct it should be somewhere around 5-7% off MSRP before rebates. But like the previous post said, it’s pretty tough dealing right now and some dealers aren’t honoring all discounts.

Could you send those to me as well? I have yet to see them in an HD. Thanks

Thanks newdude. I was basing the assumption that they were welded on the installation instructions for the 6 inch rectangular model. The instructions say the HD comes with 12 M8 bolts while the 1500 comes with 16 or 2 bolts per bracket. After looking at an exploded view for replacement end caps and treads and such, I can see you are correct and they show the brackets bolted. That makes it easy enough to remove the 4th bracket if need be but I'm still curious why GM doesn't utilize that location on the 2500. Thanks for your help.

I was wondering if anyone could tell me why some of the OEM steps available for the 2500 share a part number with the 1500 part and utilize four brackets, while others have different part numbers and utilize a different number of brackets. For example the "Sport Step Assist Steps" are the same P/N for both 1500/2500 and four brackets which I believe are welded. On the other hand the the "6-Inch Rectangular Assist Steps " have different P/Ns for the 1500 vs the 2500 with the 1500 having four welded brackets and 2500 having three. Further more, the installation instructions for the second example show the following picture. The only reason I ask this is that I've been looking for a pair of take-off sport steps locally and passed on some this week that came off an AT4 1500 because I saw the 4 brackets and knew that there was a difference on these other steps. I'm having trouble following GMs logic on this one so is there any reason why something shouldn't me bolted to this "Location 3" in the drawing above? You would think that if they could standardize this, they would. Can those of you with the sport steps confirm that you in fact have 4 mounting points?

This is exactly the situation I was in and I started tracking inventory in December. On the first few months I had a few options but I wasn’t really ready to pull the trigger. I decided to order but then that turned into a mess with allocations and constraints. If I weren’t in need of a 3/4 ton before camping season I probably would have waiting until this blew over and the market returned to normal. Good luck in whatever you decide.

Agreed, definitely spray in but I can see how it may look like some type of drop in that’s either chemically or thermally activated to bond. It has a smoother, shinier finish than my LineX in my last truck. My truck is white and they didn’t spray up under the bed rails very well so when installing my tonneau it was obvious that it’s a spray in.

@BrentH I may decide to make the conversion down the road as my truck already has the 250A alternator since I have the snow plow prep package. It’s more of a nice to have at this point and if I find myself boondocking a lot then I can add it later.

Thanks Brent for all your work on this. I spoke with my dealer about installing the second battery and they were ultimately stumped on how to do it since there is no kit to convert it. I thought it would be nice for off grid camping to have a battery on the vehicle and a be able to charge it while driving between fishing or hunting spots. I ultimately just bought a parallel battery for my camper and will use my suitcase generator.

Yes, wait for the actual purchase for the authorization code, but I would tell the dealer I am using the discount and make sure they are honoring it. Agree on the price after military discount but before rebates since those could be different by the time of purchase.

Picked it up yesterday and yes I’m relieved that this is over. Things just got crazy with the wait and constraints and not knowing when the truck would be built. I’m glad I made the call to cancel my order find a truck in route.

I was able to use the supplier discount yesterday. Even though we had agreed to the terms before the truck was delivered, it was still accepted by GM. So unless it is a regional issue, GM isn’t the issue.

That's great, Congrats on the beautiful truck. I just found out mine arrived yesterday, is going through PDI today and I'll pick it up tomorrow.

Duplicate post.

I put a deposit on a Sierra 2500 SLE last week using the educator/supplier discount. Before that I spoke with 7-8 dealerships throughout the northeast and only 2 were not honoring it. With that said, those were dealership decisions and not GM. I hope my signed work up and deposit hold up, the truck is due to arrive on Friday.
