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

Yeah, definitely no interest in paying for it. Now, if they gave it for free, I would gladly accept. ?   Has anyone figured out a way to record the rear view mirror camera. Seems like such a

Does anyone think GM would/could offer this for the 2019 models? 

Could? I don't know. Would? Absolutely not.  Then you'd have no reason to trade up for the 2020... ?

Can anyone tell me if ACC can be disabled and normal cruise control be utilized?  If the 2020 only has the ACC available and it works as well as the Yukon did I am going to snatch up a 2019 quick. 

 

I am not a fan of GM's adaptive cruise control at all.  Had it in both of my wife's 2015 & 2016 Yukon Denalis and it was horribly inconsistent.  Overall ACC defeats the purpose of setting a speed, if it varies with all the left lane idiots in front you become one of the left lane sheep.  So, I am looking at end of year deals on 2019 Sierra Denalis and know the 2020's have ACC.  Any insight is appreciated.

If it’s like most current products hold the cancel button to disable ACC.

So you have both traditional cruise control and adaptive as an option to use?

It should, I can't seem them going back on that it was a relatively new feature/function.

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 shut off ACC but still have regular cruise.  Whenever I use the ACC on trips at least once or twice per trip the car will incorrectly detect a car in front of me and slam on the brakes.  Here I am on the freeway traveling 75 mph and the next second I'm at 55 mph.  This is extremely dangerous especially if there is traffic behind me.  You have to shut the cruise off or slam on the gas to get it going back up to speed.  The owners manual says ACC may not work properly on hilly or windy roads.  Uh, hello, that's pretty much every road here in Washington State.  ACC is a horrible system that makes me not want to buy a GMC again.

Guess i can stop complaining about the k2xx 2014 - 2018 trucks not having ACC.

I'd be very surprised if the 2020 with ACC didn't have the option to switch over to conventional cruise control.  I have two vehicles with ACC and both allow you to switch over to regular CC.  The owner's manual should have instructions on how to do it.

Below is the reply I got... certainly not going to invest in adaptive cruise :)

 

its doable but its a huge job, different camera, adding a few modules, steering wheel change, cluster programming, bcm programming etc. Doable but pretty expensive :(

Define "pretty expensive"?  I'm sure it's something I don't want to pay that much for, but just curious on what it would cost, since I do about 60 highway miles a day. 

 

Thanks!

I have a 2018 Suburban with ACC. If I had realized it when I bought the truck I would have passed on it, I hate it. I can verify that the hold the Cancel button to revert to standard CC does not work on these vehicles.

Sees the 2020 Sierra Owners Manual says that the ACC can be switched back to regular cruise, if desired.

 

Switching Between ACC and Regular Cruise Control


To switch between ACC and regular cruise control, press and hold *.
A Driver Information Display (DIC) message displays.

See Vehicle Messages pg 156.

 

When ACC is engaged, a green indicator will be lit on the instrument cluster and the following gap will be displayed.

When the regular cruise control is engaged, a (different) green indicator will be lit on the instrument cluster; the following gap will not display.

 

When the vehicle is turned on, the cruise control mode will be set to the last mode used before the vehicle was turned off. 

 

And there's more, of course. 

And of course, this doesn't mean that's how it works in a Yukon.  Some of GM's ACC literature indicates there may be differences in how if functions in different applications (or maybe just different ACC generations)

This. I have never driven any vehicle with ACC till I got my 2020 Sierra on Thursday. I did not even know how to use it really well till this weekend. There are 2 different icons for ACC. One is when the ACC is active the icon looks like a speedometer with a car on the top right. The other when it's not active is just the speedometer. I read the comments above and looked at a video on how the system works. It showed to make the system not active to press and hold the cancel button. I tried this today and it changed the icon from active ACC to non active ACC. I also got a warning on the DIC that following distance and auto braking were not active in that mode. The truck worked just fine like the old cruise in my 16 had.

 

Yes the ACC is not standard. It comes on the Driver Alert Package 2 which is included in the SLT Premium plus package that my truck has.

      Well one of our most reliable vehicles was sold yesterday. The first and only I gave for free to a grandkid. If they got skin in the game they take care of it. My wife bought new. Five years later my daughter got it to use. We got it back and gave it to our grandson after graduation. He did zero maintenance just oil changes. When the AC quit he drove his mother’s car rather than get it fixed. Instead he just bought a beater and sold the Elantra.

      OCI, not when but why?

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.
