Make sure your fuse box is all set (bolts tight). https://www.tsbsearch.com/Chevrolet/PIT5756 On my 2020 (since traded) I had some electrical gremlins and when I checked all of my fuses seemed to be loose. I could push them all back in. All of my bolts were tight (dealer verified and inspected per the TSB guidance). After that I didn't have any more issues. This thread may be helpful. While not the exact same problem a lot of electrical problems are caused by the same issues.

Not all dealers are doing this. This is not a GM requirement to sell at a higher than MSRP price. This sounds like some shitty dealers taking advantage of the shortage and demand of trucks. I just bought a truck last week (AT4 with 3.0). almost 10k off sticker. With the good rebates that GM offers right now it is putting even more pressure on what inventory there is.

After 2 different production delays I finally got my AT4 10 days ago. diesel noise is only noticeable when accelerating. When cruising the truck is quiet. I actually think it is quieter than my TB. 430 miles and 22.3 MPG for lifetime which has some city and idle time. easily get 25-27 on several 30-40 mile trips.

Battery Tender does list some solar options. https://www.batterytender.com/solar-panels

Yes but I am hoping that it is also "Other drivers see me red". I had my 2020 TB for 15 months and it was Black. At least once a week I would have someone either pull out in front of, drift into my lane, etc. Broad daylight or at night. Some how I managed to avoid all of them. One of them was a 18 wheeler that ignored the yield signs...... Several times I would have died if I hadn't avoided the crash. I think the truck had a death wish.

It is listed with "Rated up to 400 lbs. of evenly distributed weight". Not sure how that translates to crush weight. I ordered the MX4.

My truck ended up being able to remote start with low fuel (2020 Trailboss w/ 6.2) so I must of been remembering my Ram. I would assume that my 2021 Sierra is the same.

Sorry about making contact with bambi. Hopefully you get it fixed and back soon.

So far I love it. Power is really good. Not the instant off the line power of the 6.2 that I had but over all very good. Averaging 22.3 over the 230ish miles I have put on it. Mix of city, country roads and highway (75-80) with a little bit of idle. I have had a couple trips around 25 miles that were around 25-27mpg (mix with no highway and minimal stops) and another one that was 65 miles and was a mix of all driving (mostly highway and country road) and got 24 mpg.

Sounds like what my previous cover allowed for on last truck. Thanks.

Power tailgate still work with the cover? Did you install the drain hose at the front of the bed?

Did you install it yourself?

I was looking at that cover too. Do you have pics?

Anyone have experience with this cover? https://bakindustries.com/revolver-x4s/2021/gmc/sierra-1500

2021 AT4. Cardinal Red. 3.0 duramax. adding the off-road steps this week and a cover soon. Also will be swapping badges to be black for the AT4 and GMC logos. Black exhaust outlets too.

I could be thinking of my last truck. I’ll try it next time my fuel light is on.

I have the 6.2 w/ the 10 speed. 13k miles. Mixed driving of highway, country roads, in town driving. Some idle for warm up in the winter and cool down in the summer. my life time mpg is 14.8. I can get 18-22 when not in town. highway is more around 15-18 as I am usually around 80 mph. I drove a 3.0 last November 16.4 mile test drive of mix of in town and country roads and averaged 24.8. This was in a brand new chevy LTZ. while not quite as snappy as my 6.2 having all of the tourqe available at 1500~ RPM is very nice. I thought the power was more then acceptable. I didn't get to drive on the highway... For the the added MPG etc I have an AT4 with the 3.0 on order (if it ever shows up). I will give up a little bit of stop light power.

Go to dealer to get reason for code. FYI--low fuel (warning light on) also will not allow a remote start. I know this isn't your problem but just wanted to share/add.

Hopefully my truck is in there. Been waiting since Nov 23 due to 2 different delays......

between those 2 the GMC. 10 speed.

I currently have the 6.2 and before I ordered the 3.0 I test drove one. I was very surprised at how well it drove and the power/responsiveness was very good. Not as good as the 6.2 but with basically all the torque available at 1500 it is very good. Plus the MPG is a huge increase.

Utility trailer?

For those of you that have a truck on order or are placing an order soon be aware that there is a delay/hold if you order the truck with either the AT4 high clearance running boards or the offroad running boards. This seems to be the case when ordering them if they are part of a package (AT4 Premium package) or as a separate add on. My dealer had to modify my order. Removed the premium package and replaced with the value package (same options just the value doesn't have the high clearance running board). Also adding the offroad running board put the order on delay. When I initially placed the order the value package didn't exist. My salesman had to work with his GMC rep to figure out what the hold up was. Other trucks they ordered about 2 weeks before mine had already been delivered and sold. My truck was originally ordered on Nov 23. There were constraints on the duramax first and then the running boards..... Once the offroad steps are in stock I will order them. My son (special needs) can't get in the truck without some type of step.
