I just bought a 2020 gmc 3500 AT4  ..I am trying to figure out if I have it???  It says LD model only??   I have been looking in manual however, it does not appear that I have?  I spent over $70K fully loaded you would think this would be included????

2020 HD models do not have ACC available on any trim level.  LD is Light Duty models, which is the 1500, and they only got it in 2020.  HD models should get it for 2021, but no confirmation yet from GM.  And if not in 2021, certainly in 2022.

LD only. There are lots of threads about this.    And everyone here knows what they cost.

I have a 2019 Yukon SLT with adaptive cruise control and if I could I would trade the car back in for one without ACC.  The only way to shut ACC off is to not use cruise control.  There is no way to s

Didn't show up in the 2021 HD Order guide...

 

(of course it could still appear in an order guide update)

I would pay pretty damn good money to add ACC to my 2020 Sierra 2500HD Denali. I have the Ultimate package, so I have everything, but I am dying for ACC. I just bought the truck, I knew it didn't include it, and I know the 2021 doesn't have it. I swore my next truck was going to have it but I really didn't want a Ram or Ford.

 

What's it cost? If a company came up with a solution, I would definitely be interested....it would be cheaper to add it then it will be to trade in a year or so when it's available.

I agree with you. The ACC is the reason I traded in my 19 Trail Boss for the AT4. Once you have it (previous Volt), you want it in every vehicle.

Has anyone figured out a way to record the rear view mirror camera. Seems like such a waste to have to buy and install a rear view dash cam when there is a perfectly high definition functional one in the car. Maybe GM can do us a solid like what Tesla did for their customers. Tesla vehicles can now record from the cameras unto a usb flash drive. I would actually be willing to pay a little to have this feature. 
Is $1,000 fair enough of a price?

I had this included in my deal when I bought my truck. The cost to install is actually more than the unit itself. Dealership charged about $520 for the install.

It will "work" with lots of programming involved according to the community developer using the comma's system to interface with GM's control modules, it is out of reach for anyone that does not have the ability to modify and program ECM or any other OEM modules. I am following the community group for GM, it is doable with vehicles that has only Lane Keep Assist, the openpilot system will take care of the distance and keeping the vehicle in the center of the lane. Having Lane Keep Assist ensures the vehicle has the digital means to be interfaced for steering.

 

I have a 2020 AT4, Adaptive Cruise Control can be turned off, but it actually works really well. I do want to point out, I had my old truck's snow tires on when I first got the 2020 AT4, the Adaptive Cruise Control was acting strange, feels as if it is a little slow to make changes to speed or apply brake. After I changed to 33.5 inch tires, Adaptive Cruise works very well. The vehicle has the ability to stay in the center of the lane, but GM has limit the amount of steering assist it will provide.

Where is that community you follow? I currently have a ‘19 AT4 with lane keep assist, if I can get open pilot to work with that and allow me

to end up with ACC I would love it. 
 

Thanks

I know Openpilot doesn't officially support it, but I would be curious if it could be made to work and if anyone in the community has tried it on our trucks. I've considered buying it for some of the longer trips I take so I don't have to upgrade next year to super cruise. The ACC in the high country could just be slightly better for the lane keep on major highways and I would keep my truck a very long time. I know you guys are looking for just the capability of ACC, but I would like a little better L2 driving.

There are quite a few hardware changes to make this happen (more than you'd think ;)) if this is something you truly want to do drop us a line from our site  and we can discuss it :)

I am interested in this. What is your site

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.

      "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
