I just traded in my F150 for a GMC Sierra 1500. Not real impressed so far. One reason I went with this specific truck is it has adaptive cruise control. After a week of driving, it’s starting to disengage the adaptive cruise and make it “unavailable.” It happened about 10 times on my 80 mile drive yesterday. The truck’s spotless, so no issues with something blocking sensors. Anyone else have this issue on GM vehicles?

You might have a sensor issue. If the computer senses any kind of issue with being able to “see” objects with the sensors it’s going to shut it down.
This could be. I drive mostly empty highway, so there isn’t much to detect most of the time.
Under warranty? Have them fix it.

I have a 2016 Sierra but no adaptive cruise. It is a 4x4 with all the bells and whistles. A/C seats are awesome in the summer. It’s been a great truck but I have to learn to live with the hard shifting 10 speed transmission.

That’s not normal
it’s not supposed to just shut down unless you take action to. You have some kind of issue. Take it by a dealership and get that seen about under warranty.

First mistake right there. I did the same thing several years ago, traded my F-150 for a Silverado and had nonstop issues with it until I finally said to hell with it and eventually went back to an F-150 and have not had a single problem with it in the 7 years I have been driving it.
There are so many things that start rattling in a Ford truck that it becomes unbearable. The quality has gone way down.
I’ll do that. Now I have the joy of leaving my vehicle at a dealership for days on end for them to tell me they can’t recreate the issue. Less than 1,000 miles and already planning a visit to the shop.
My wife’s ‘18 Expedition rattles pretty bad. Then again she treats a vehicle like a Bammer fan treats his dog after a loss to Auburn.
Keep the Sierra and get it fixed under warranty. Every manufacturer has some issues but never I repeat never will I purchase another Ford.
You and I have the same issue there. I swear... if my wife's passing a weaving 18-wheeler on the freeway, she'll hang out in his blind spot for seemingly an hour while eventually going by him at a speed of exactly .5 miles/hr faster than him.
On the other hand, if she needs to get by a Prius on a wide open road, she'll gun that thing like she's trying to win a drag race, and I can practically hear the transmission screaming for mercy

“Our technician couldn’t reproduce the problem, sir.” Get ready.
I’d recommend trying to film the issue if you can do so safely.
Toyota and GM were the most stubborn about honoring warranty IME. Ford was so-so. Honda has been great. All anecdotal.

Sounds as if you traded with the wrong dealership if you have that little confidence in them.
i have that little confidence in most dealerships. I bought from a dealership about 3 hours away, so they won't be my service location.
FYI, the brand of the vehicle has absolutely nothing to do with how stubborn they are about warranty. Dealerships are independent businesses that are totally separate from not only the manufacturer but also the sales division of the manufacturer. They also make just as much money from warranty repairs (if not more) as they do from out of warranty service and repairs. Manufacturer reimburses them a premium amount compared to the hourly rate for normal repairs and service, and they also have carte blanche to do just about whatever troubleshooting they want on the manufacturer’s dime if the problem is not easily reproducible.

Don't know how the adaptive cruise control works on your Sierra, but on my Subaru there are two cameras at the top of the windshield on either side of the rear view mirror. Basically, it can't see under conditions that you can't see well under - into the sun, hard rain, fog spray from other vehicles, etc.
How was the weather when yours quit working?
No it started on Friday, which was the first dry day we’ve had since I got it.
Good, sunny. It works, but after 20 miles or so it disengages. Then from that point until the end of the drive, it works for a few miles then cuts off repeatedly.
Don't 17 around with American Manufacturers, get a Tundra, it won't have AC shooting up your bung hole, but it rides good, has plenty of power, the biggest back seat and will operate for a decade/200k+ miles with no mechanical issues.
i bought mine at Phil Moore GMC in Jackson and had to leave it a few times and they always gave me a Sierra to drive. No need to overthink this.
No. A message “Adaptive Cruise Control Disengaged” pops up. Then if I hit the resume button, it says “Adaptive Cruise Control Not Available”. I can switch to regular cruise without issue. I can also completely turn off cruise and start again; it’ll go a few miles then repeat the disengage. This starts after about 20 - 25 miles of driving.
I absolutely hate adaptive cruise control. My wife's car has it and I just use the regular cruise control. I hate it constantly slowing down and speeding up on the interstate. I usually stay in the upper 70's while driving and it's just annoying to me as a driver.
I see I'm not the only one. It's not like I'm ever going to hit the car in front of me anyway, so it's pretty useless. But then with the false positives (slowing down when there's no need) and especially the false negatives (not slowing down when it should), it can be dangerous by lulling drivers into a false sense of security while they're texting on their cell phones.
I like mine too but it takes a bit of getting used to.
I have heard of people (none here) that use it on urban freeways in heavy traffic, and it's just not designed for that sort of thing.
See, I've always heard just the opposite. The manufacturer reimburses them for warranty work - but it's at a lower rate than they charge customers for service work. So if a dealership has their choice, they'd choose normal service work.
It's also my understanding they get paid for the actual warranty work - but not for the time they spend unsuccessfully trying to reproduce a problem. So if it's not a common problem, there's no error code logged, and you don't regularly bring your car into their shop for service - they're going to be reluctant to try and diagnose it.
Any service managers here who can tell us how it really works?
My experience with adaptive cruise control seems to always be as follows. On rural section of interstate, driving 78-79 or so in RH lane. Have another car about 50 yards behind me traveling about same speed. I come up on vehicle ahead of me going about 70, so I make a move to get over, except the ACC kicks in and slows me down before the lane change. This causes the car behind me to get over and pass me, and I have to wait on him before passing the original vehicle. The only other option is to proceed with the lane change anyway and then you cut off the guy behind you.
The biggest problem is that this encourages everyone’s least favorite driving behavior, getting over in the left lane earlier and staying there longer to avoid being slowed down by the system. I’ve also had other issues with things like bridges and construction barrels being picked up by the sensors and slowing you down for no reason at all.
It’s not beneficial on busy interstates, but I drive rural highways, so it’s nice to set it and sit back. Every once in a while, I come up on a car and it takes care of the speed until I pass. I got very used to it in my Ford, which worked like a charm. It creates a risk when I drive non-ACC cars and forget I don’t have ACC. That results in some unkind language from your spouse sitting shotgun.
Stop-Start isn’t exclusive to Ford....most all OEM’s are using it now to help hit CAFE targets for their fleets. And yes, it is universally annoying.
Regarding full-size trucks, it would appear you may be correct, at least in regards to the Silverado.

Oddly enough, the GMC at the higher price point scored lower than Silverado in terms of reliability, and was equal to the F-150.
