Anyone have issues with the Supercruise with the roof panels off? When we were test driving one on Friday, we took the panels off and it was mid day and bright sun... Supercruise would not engage or stay on because it said that it couldn't see my face... Just curious if anyone else has had that issue..
I find this hilarious for some reason.
 
I’ve had mine brought into the dealer three times to fix the super cruise issue. Each time I bring it in they tell me there’s a new software update that will fix it but I still run into the same issues on maps roads.

For instance, driving up I 70 from Denver to Frisco all of I 70 is labeled as super cruise enabled and mapped. It also shows us on the map in the truck itself. But then I’ll get the random no road information and a disconnect. It happens about 3 to 4 times traveling in each direction. This is the part that confuses me about super cruise because I didn’t think it was dependent on having cell phone signal the entire time. I thought once the modules were updated then it just worked regardless of your cell phone coverage.

Yesterday I got the super cruise unavailable message. I ended up pulling over in a parking lot, since my wife had to go to the restroom anyways, and doing a full reboot on the truck via power cycling the truck with a five minute off period and then a reboot of the entertainment system. Super cruise then worked again. The truck was just in to fix this issue in late July. I figured I’ll deal with what I have until a real fix comes out.

When it does work though, it is one of the most fantastic features! Navigating the roads of I 70 through the mountains with traffic has to be the ultimate test. It does an amazing job! I never thought I would enjoy a vehicle driving me down the road at highway speeds while I just monitor it. It’s super fantastic.
 
Supercruise is impacted/directed by the mapping module, when/if the mapping module is malfunctioning you typically get the “Service Driver Assist System” warning notification in the dash/instrument panel, which disables SuperCruise amongst other things. Since purchasing my Hummer SUV Edition 1 back in January, I have continued to get the Service Driver Assist warning and SuperCruise has malfunctioned for 8 months & counting. I have taken the vehicle to my dealer tech repeatedly, undergone countless module re-programming, updates..until finally the mapping module was replaced..twice..and both times GM-TAC in Detroit ensured the new mapping modules had the parameters properly set before shipping. The malfunction remains to this day..and GM-TAC in Detroit’s resolve?..”it’s a known software anomaly that will be fixed soon with upcoming OTA’s. It’ now September, what OTA’s??!! My dealer technician is fantastic and only services Hummer EV’s, he’s well known and consulted on by other Hummer technicians for help nationwide. In the last month he instructed me to bring my Hummer in immediately whenever I receive the Service Driver Assist warning, so he can try to diagnosis real-time for resolve..but the same steps get repeated via GM-TAC. I’m not going through Lemon Law protocol. I’ve posted this story several times to offer factual insight to others..and maybe, just maybe..that the Moderator here would assist me somehow, direct me to higher management in GM for attention, etc..something besides instructing me to make sure my dealer technician did the required firmware update before/after installing the new mapping modules.
 
You can reach out to mary.barra@gm.com and politely explain your situation.

You will also get that error message if the sensors/cameras are dirty, misaligned, or not properly connected. It isn't just the module.

If the module was replaced you also need to go through a calibration process on each of the cameras. It isn't just plug and play on replacement.

I think you are right that there is a a process/commissioning after updates that some of the Hummer Techs are missing. My assumption is the written direction for the techs is missing items related to a required step by step process, or a final calibration moment that there are not doing. If I remember right (mine was done about 5 months ago) my tech went on an internal chat with other Hummer techs who had tips on what was needed beyond just grabbing the newest update, seemed like he was just going through like an initial setup/calibration process but it might also have just been a specific order that things need to be done in. Whatever my tech saw, it worked because it has been great in my hummer for a long time now.
 
SuperCruise is a SUPER disappointment. This option rarely works and when it does, it usually is not for long. I don't think i have ever made it more than 15 miles on the interstate without being informed that roadmaps are unavailable. Most times it will go a few miles, give me the warning and i can usually re-engage and it will work for a few more miles. Sometimes on a return trip, it works in the exact locations that it had not worked earlier in the day. I had it in for service yesterday and they said it works as expected, that if the maps are not available then that is not the problem of SuperCruise. WOW!
I have only owned this thing since May and I have quickly realized why i had left GM years ago.
 
They just ordered a new mapping module for me, takes two weeks. Should fix it. They did a recall for some ‘22s for a bad batch of modules from a supplier…seems like it should have extended that recall.
Thanks for the info Carac, i will reach out to my dealer and ask if this is an option for my vehicle.
 
There are usually two reasons Supercruise isn't working:

1) If it says something like "No Road info" that means it's on, initialized, and functioning but either the road you're on isn't mapped or the data connection sucks so bad it can't download it.

2) If it says "Supercruise Unavailable" that means that the system didn't initialize when you started the truck. i.e. it couldn't verify some part of the system was active, couldn't confirm you have an active subscription, etc. Here's the part that's so stupid I can't believe it made it to production...it doesn't reattempt to initialize until the truck is off and sits for some amount of time. It doesn't recheck every 30-60 seconds until it works...it basically throws up its hands and gives up until a power cycle. That means, if you're just setting off on a 3+ hour stint...you just don't have Supercruise until you pull over, turn off the truck, wait a couple minutes, then restart it (preferably in an area where it has a data connection). Out of everything involved with the truck that is the most mind-boggling thing. Why the hell doesn't it keep trying to get the system functioning. It's the vehicular equivalent of the worst employee ever. Like if they mistyped their password or keyed a door code in wrong and just went home. If the service sheet from my battery swap is correct and they DID update the Supercruise module it didn't do anything, which means I'm probably due a Supercruise module and wonder if the limited recall they did on the module shouldn't be expanded.
I can't for the life of me understand why you have to pay extra for this or it just won't work.

I was told by GM that the face recognition sensor on the steering column is not great and fails a lot shutting sc off.
 
it's free for 3 years no one is paying for it for the first several years of ownership.
 
Yes I realize that. I don't feel that should be a paid subscription after that through onstar of all people.
Super Cruise uses constantly maintained 3D LIDAR scanned maps of the roads that are fed to the vehicles modules. Yeah I'm fine with paying for this reason.
 
You make it sound fancy, it's not really. I don't think it should be a paid service at the hummers price.
Because it is fancy. These aren't flat maps like in Google Maps. The maps are 3D Scans of the road using LIDAR scanners by a specialized 3rd party company. GM uses these maps so the vehicles know where they are in a 3D environment.

These maps constantly change and grow. Next year there will be over 700K Miles of mapped roads in North America.
 
Mine works very well 95% of of the time. Every month or two I have a 2-3 day spell where is is really bad, engages for 10-20 secs then kicks out. Always goes away eventually. I have a 2023 ED1 Truck, maybe it’s an issue with the newer ones. I have noticed more two lane roads being added every month. Just on a State Road last week that has been added recently. Bummer its not working well for you.

The technology never consistently works for me on the same roads. I'm not fine paying for an underperforming service.

I bet an open source solution would rival Super Cruise if we.had the means. Something like what OpenStreetMap did to compete against Google Maps.
 
SuperCruise is not reliable and problematic..that is a fact. Regardless of 3D LIDAR technology..or any other technology..if SuperCruise fails to perform as advertised to me as the purchasing customer then the feature is worthless to me. Furthermore and more importantly, GM was/is fully aware that SuperCruise is a well known and ongoing item of malfunction, at least with the Hummers..and GM knowingly and continually highlights SuperCruise as a working feature. If something is free/don’t have to pay for it for a period of time..but it doesn’t work..ya well enough said!
 
well then I suggest you make sure you have a strong Cellular signal on those days it isn't working. Just a suggestion.
