Wondering if it is possible to add adaptive cruise to my 2019 Sierra (it is loaded with all safety features front crash, cross traffic, following distance, etc.)  It this  just a different module I  can install, or is this simply too complex to do?

 

All input is welcome.  Thanks!!

My understanding is that all module 2 module communication is encrypted with unbreakable code

so it looks like I'm this generation you will not be able to add any modules from higher models.

That being said me just poking around it appears that every model has the same wiring harness.

I'm with you.  I wish this was possible as I have every option in my 2019 Denali, except for this.  Guess this is what I get for buying the first year of a model change.

I have the dealer researching this for me since I was not able to get any useful information from GM on the question.  I will share what I learn here.

 

I had a loaner with this feature for the last month, and it works really great.  No need to keep shutting it off when some jumps in front of you and slows down; the system just slows to match their speed and then speeds back up to your setting when the path is clear.  Really nice feature to have if you do a lot of freeway driving like me.

All right so originally this model was actually never going to have adaptive cruise control that's also why the HD doesnt have it. GM decided to add it very late in the development phase that's why it's based on a camera not on lasers or other radars.

Thanks for the comment topgear.  I was thinking that it used the radar for the following distance warning and the front crash auto breaking, which mine has both of those features.  It may not be possible if they added a seperate camera or laser just for this.  I will share what their answer is regardless.

On the models with adaptive cruise there is only 1 camera, the same single camera location used for the enhanced safety features in my 2019 Sierra Denali.  

I had a loaner 2020 AT4 with adaptive cruise. Only difference I could physically see was a different part number on the camera.

My understanding, very limited, is that it uses the camera for primary recognition and then it taps into the other sensors such as the following distance sensors to check its self. but notice how your following distance sensor doesn't really lock on to a vehicle until it's kind of close? That's way too close for adaptive use. imagine you're doing 80 miles an hour in the left lane and a car pulls out at 45 4.5 seconds isn't really enough for the truck to understand, interpret and apply the brakes in a way that doesn't give you whiplash.

GMs most recent generation of truck for both heavy duty and light-duty were both rushed to market a bit earlier then ideal. but at least they didn't cop out and pull a ram where they spent an entire redesign Budget on just redoing an interior and putting it on an old chassis with slight modifications.

Owned 2019 Ram 1500 Laramie 5.7 4X4 it was clear that vehicle was rushed especially in its dynamics. had a nice interior the issue is when you have that nice of interior Small things become a very big problem such as slight defects and panel gaps. wind noise was also unbefitting of the truck they really should have given it double glazed windows. and weird things like it has a drawer on the bench seat model that wiggles. things that you normally wouldn't care about in the pickup truck but when you have that nice of interior, you expect it all to be nice and the fact is the Rams simply isn't good enough to make up for its dynamic shortcomings.

The description of the adaptive cruise control on the 2020 GMC Sierra’s is “Adaptive Cruise Control-Camera”, which means it doesn’t not contain or use a radar, only the camera.

In contrast, my 2019 GMC Yukon Denali does have a camera and a radar module based adaptive cruise and is described as “Adaptive Cruise Control-Advanced” which means it uses both the camera and the radar (advanced).

My dealer tech that works on these says it is not possible to add this to my truck - too many expensive things to add/change and program.  There are new steering wheel controls, dash indicators, error reporting modules, etc.  Guess I will have to wait until the next truck.   Thanks to all posters for the great comments and content!

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.
