CC works sporadically. Many times, I cannot get it to engage. Dealer couldn't diagnose the problem. What to do?

There has been some chatter about this. Mine does the same thing sporadically. Tap or lift the brake pedal and try it again when it doesn't work. I haven't had to try that yet but others say it's a brake pedal issue. I think the dealers should have a bulletin about it as well.
There are threads about a problem with a switch associated with the brake pedal.

If the dealership won't look into it and it's still under the B2B warranty, I'm sure Amber in customer service who monitors this forum will contact you and arrange for service elewhere. I'd never set foot in that particular serine department. I currently go to a dealership 18mmiles away as opposed to the one 3 mile away because they 18 mile place is far more talented (and Paula and Dawn are far prettier than Michael and Kevin)

Thank you all for your feedback. Very helpful. And pardon an (almost duplicate) post from me if it appears; this is my first time using the forum, and I didn't realize that my question above had been successfully posted and replied to, so I posted the question again!
Cruise control quits
I've been reading through all the posts regarding cruise control not working intermittently. I have the same problem, but the dealer in Warrenton, Oregon (31 miles from me) will not touch it unless it is not working while at their service department. Of course, it always works when I am there. Is there a service recall bulletin on this problem yet? Any other suggestions?

I have read a post describing slightly mis-adjusted brake pedal switch but haven't had luck finding it. The poster had elongated the hole in the switch bracket, re-positioned the switch and, after tightening the bolt, applied hot glue to prevent any further relative movement between the switch and the frame. He solved his CC problem that way, I believe.

in case you really have a bad switch.

For the first time, I just experienced a problem tonight while driving with the cruise control. It would not engage at all. I stopped the car in a parking lot, turned it off, then on again and drove again. The cruise now worked on the first button push, but then not at all after trying to get it to re-engage after braking. I arrived at my destination, parked, came out again 2 hours later and began to drive home. The cruise control wouldn't engage at all at first. However, after several failed attempts, it started to work again and everything was fine for the rest of the ride home. I took a small video on my phone which documents it not working, and then working again, so it is proof to the dealer if I bring it in.
A couple of weeks ago, my ICE came on despite the fact I had not put the car into hold mode and there was almost a full charge. It wasn't due to temperature, or old gas, or having the hood opened. I posted about that, and so far the problem has not occurred again...but could there be something related between the 2 different things that have happened?
My car is 2 years old and has about 32K miles. I'm thinking I should bring it in to be fixed, but am doubting that they will be able to duplicate the problems and figure it out. But maybe I need to do this just to document that there was an issue while the car was still under warranty.
Thoughts? BTW, no error messages for either problem.

next time it happens, put your foot behind brake pedal and pull it towards you(opposite of braking)see if it starts working,
if it does, could be your brake switch
if it does, could be your brake switch
Probably not applicable to the cruise in your LT, but the Adaptive Cruise in my Premier got flaky on me the other day and eventually would not engage at all. At the same time I noticed that my regen seemed to be much weaker, both when driving in L and when using the paddle - It was only maybe 60 to 75% or so of normal
Both problems turned out to be tire pressure. I didn't have a tire low enough to set off the TPMS - All 4 were at 33 or 34 psi and when I aired them back up to 40, everything was working normally again and it hasn't done it again since

So, cruise control today was working fine. If it does act up again I will definitely try that pedal trick, lifting it up. The 12 volt battery is fine, and the engine has been run often enough that "6 week fluid recycling" is not applicable. If the cruise control switch is dirty, I would be surprised...my car will be 2 years old in a week, so it isn't very old. I've never had a problem with cruise control in any other car that I've owned, and I usually hang on to my cars for quite a long time. Maybe I should just bring the car in to to the dealer and ask them to fix it. In 2 years, I've had quite a few little issues so far with this car, more than any car that I've owned. I'm starting to lose patience over its lack of reliability. However, when working correctly, I've enjoyed this car more than any other that I've had.

A couple nights ago the problem happened again. I was driving for about an hour on the highway, and could not get the cruise control to engage at all. I tried lifting up on the brake pedal, as suggested by others, but it didn't change anything. I got off the highway, turned the car off and then back on. The cruise control was still not functioning. Then, while at a stoplight, I pushed down really hard on the brake pedal while already stopped. The stoplight turned green, and as I got going, I tried the cruise again. It worked a couple times, but then not at all. I got to my destination and parked the car. 3 hours later, I started the car to go home, and now the cruise worked perfectly with no issues. It is still working now 3 days later. I don't know what to do about this intermittent problem, because if I can't duplicate it to the dealer, I don't think they will fix it. I am coming up on the end of my warranty, since my mileage is at about 32.5K miles. Any suggestions on how I can get action if I bring it into the dealer, and if I can't duplicate the problem? I really am frustrated with this. I've had quite a few little problems in my 2 years of ownership with this car. When I drive on the highway, I want my cruise control to work, and not have to hope that it will! I don't have an extended warranty. I've always thought they were a waste of money, but maybe in this case it would be a smart investment given my experience so far.
Sounds like an intermittent switch problem. I'd change out the brake switch first as it is likely to be cheap(er) and easy to do. Or you might have an intermittent switch on CC (not so easy or cheap).
I had an intermittent aftermarket CC on my '91 Integra and I found if it didn't work sometimes switching it off then on again would appear to reset the electronics. I didn't use the CC often (which might have been part of the problem) so wasn't too concerned but could usually get it working after fiddling with it a bit by turning it off and on then setting it.

Cruise control in the VOLT or any other car has a brake switch to cancel cruise during a brake application. Last week my cruise failed the resume command so I lifted the pedal up with my foot hit resume and it worked. I also have not found the switch location if someone will share where it is we can clean or replace as needed.
The brake pedal switch is called the "brake pedal position sensor" in the Chiltons online library.
"Thaniel" pasted a link from the NM Library system that you can use to log in to Chiltons with:
https://gm-volt.com/forum/showthread.php?282505-Free-Service-Manual-access!/page2
select your car by year make model, might need to cheat and go one model year earlier. it only goes up to MY2015 so far.
click select and wait for a page load.
click on the "repair" link and you are brought to a Table Of Contents page. click on the search glass near the top of the T.of C. and type in: brake pedal position sensor
hit enter and you get a listing that will include: Brake Pedal Position Sensor Replacement
this will give you the pictures of where to look and how to remove and replace the switch.
Brake Pedal Position Sensor is located up above the brake pedal sort of awkward to reach...
I had the same issue on my suburban and this same switch was the culprit. remove and replace and the Cruise control should work, because the malfunctioning brake position switch will no longer be sending a "cancel" signal to the cruise control logic circuitry.
YMMV
Cheers.

eDommer, I'll assume you have ACC. Your problem is normal. My '17 Volt also disables the ACC in moderate or heavy rain. Guess why? The radar sensors that are "seeing" the car in front of you are being overwhelmed by water and the system shuts down to protect you. If it didn't, it may keep your set speed and hit the car. I'll bet those here with the "normal" CC do not see this shut down as the driver is used to manually keeping distance with cruise. (And really, nobody should be using cruise in those conditions anyway).
