2024 Sierra Denali Ultimate in Sterling Metallic

Did you purchase from Rockwall GMC? I just purchased my 2024 Denali Ultimate from them. Great price but less than thorough salesman and after sale info. Overall ok though.

Only temporarily. There is definitely something wrong with the 2024 SW version as my 2023 worked great. The speedo on HUD & DIC have both gone away and GM CS has said to take it to the dealer, which is what the next step is. I'll post an update after that visit in a few weeks. I will not accept anything other than it working all the time on a list price truck of$89000!!! GM needs to rectify this ASAP!

I'm having this same issue, similar chain of events. This seems to be a 2024 issue as my 2023 worked great. Talked with Onstar & GM customer support for hours, twice-resetting everything. The speed limit sign works only in certain areas and there's no rhyme or reason to it. It doesn't work at all where I live. My 2023 worked fine everywhere. GM told me it needs updating at the dealer, that's the next step for me.

It's absolutely horrible. GM must have been given a ton of money for this crap!

With the vehicle running and in park hold down the "end call" button for 15 seconds. Head unit will hard restart. You can also with the vehicle off open the driver door for 2 minutes. Not sure what this does but it was a troubleshooting step by Onstar. These were both told to me by Onstar to try and get my data and HUD speedo working. I just wanted to share the info here. If having Onstar issues or data issues you may also try resetting the head unit in the settings menu. Reset and clear everything out and start over. Clear the vehicle from your phone also.

I had this same issue after my purchase went through, after the dealership let me use the truck for a few days until my check came in. I was on the dang phone with Onstar & GM rep's for over 2 hours. Terrible support. Finally an Onstar guy helped me with the following steps. There is a hidden reset for the head unit. With the truck on and running HOLD the 'end call' button until the head unit turns off (15 seconds). It will reboot and takes a few minutes. After it all boots up you may want to shut off the truck and open the driver door for "2 minutes". If this doesn't work, go through the process of resetting the settings in the 'settings' menu of the head unit. Reset & clear everything! Finally got all my speedo stuff and data working after that last step.

GMC customer support is now in the mix, for what it’s worth. They contacted the dealer and relayed the same message I was told by the dealer. Not sure how that is helping but that’s the facts. I thought there might could be a way to contact other dealer parts dept.’s to try to find a headlight but I’m just using common sense. If I could I’d drill some holes to allow the condensation to escape until a new one is installed but I seriously doubt they’ll allow that. I’m sure the light can be remanned by someone but it’s going to be harder the longer it’s wet in there. I’m actually surprised it’s still working. I’ll update when I get it replaced.

Is anyone experiencing dealers unable to do warrantied repairs for lack of parts available? Purchased my 2023 GMC Sierra SLT in January 2023. I've had a damaged (full of condensation) headlight since October and all I can get from the dealer SA is "it's on backorder". Pretty ridiculous if you ask me. If they can make new ones (which they obviously are) they can spare one for a truck under warranty.

The view of my front wheels from the side is not clear (2023 Sierra). Anyone have a picture of how theirs looks? I need to take the truck in for rough idle, I might as well throw everything at them when I go.

I couldn't agree more. It's not where you want it it's how much do you want it. Especially the one to the right of the steering wheel.

I usually run aftermarket "Cold Air Intakes"(CAI) on all my vehicles. I have not looked at this trucks' air filter so I'm unsure what this Heavy Duty Air Filter actually is. I will look at it in the next few days just to lay eyes on it. My question is: has anyone exchanged this air filter for a K&N filter or any aftermarket CAI? Is it really that special of an air filter or is it just thicker or a higher priced GM filter? I did a search for this and found nothing and I'm a curious fella'. Just trying to fill in the holes here.

Definitely glad I got the 2023 with the huge screen; my old a$$ eyes need it. I kind of like the button rail down lower though. I think I saw somewhere that they just changed the start button, maybe 2024.

What'd you use to get them red?
