Over the last few months I have been having intermittent problems with Super Cruise. 99% of the time it is fine; occasionally it won't work on startup, but after the car is parked for a bit, (like a reboot) it works again; Experienced short times of disconnect while driving and then it connects. Yesterday, completely dead. Took it to the dealership and the Service Manager and I took it for a ride. DEAD as a doornail. To the shop Tuesday to see what it up. Bumer. Any ideas in the meantime?

Complex electronics/systems that become constipated and require outside the box customer intervention to work is unacceptable imo.
Perhaps a battery disconnection will clear the problem. These vehicles require a in cabin breaker switch.
Having it completely dead though could be a fuse, loose connection or maybe a failed download/update which triggers a full shutdown.
Interested to hear what is the problem.
See they plan to have SC in all Cadillac's by 2020.
How do you like the vehicle so far?

Additionally, none of the other safety features, (lane departure, etc) work now. Other then these glitches I really like it. I had a 2017 CT6 3.00TT Black on Black and really, really loved that car. Lost it in atlanta in June 2018 when an 18 wheeler decided he wanted my lane. This 2018 is that Crystal Clear Coat White. I really like it. Compared it to MB, BMW and Audi. $$ for $$, with the content, it is a better deal. It is my last car so I guess I better enjoy it Really, it is a good deal and it was a good choice.

It could be many things, but the fact it would "reset" after a longer shutdown would indicate a bad module to me, based on my experience with my wife's 2017 Acadia. Her telematics module was bad but it was intermittent and turning it off it for a time so it would completely shut down, like ten minutes, would bring it back to life. It was amazing what didn't work because of that module, not just OnStar but no voice command no Bluetooth and a bunch of other stuff. It finally got to a point that it died and could be diagnosed. So it may be the module that controls Super Cruise ahs gone bad.

On a few occasions I've tried to engage Super Cruise and it simply isn't available and won't turn on no matter how many times I try. The 2-3 times this has happened, I take the next exit off the highway, find a safe place to stop and park the vehicle, turn the engine off, immediately turn the engine back on, get back on the highway and Super Cruise works again. I purchased my CT6 new and have had it for 10 months now and used Super Cruise probably 100 times by now, so this issue is not at all frequent. At least one of the times this happened I was on a stretch of highway I don't normally drive, so at first I thought it was a lack of map data (this happened before the recent firmware update to Super Cruise - since that update the vehicle seems to provide more info on why Super Cruise won't engage when that's the case) but turning the engine off then on again did the trick.

Has anyone else had this issue?

Are you sure that you weren't "locked out" by the SuperCruise? I was having a couple of successive sips of coffee one time and the SC shut off as apparently it couldn't see my eyes, even though I could see the road just fine. I had to take the next exit, go through the stop/start sequence, and finish the coffee. Worked fine after that.

Still dead. Goes to the shop at 0 Dark Early tomorrow.

 

[khubbell]

I've had Super Cruise state it was not available because my OnStar coverage was not current. After parking for about a half an hour the system functioned again. No changes on my part.

I've also have it disconnect on our outer belt, a route that I've take many times, and when I try to re-engage the displayed message said I going too fast. I was doing 65.

They've go some bugs to workout.

Cadillac can’t even get an iPod to work in an Escalade so why would I believe their “Supercruise” tech could drive me safely home? Their technology is a joke. Learn from your experience and don’t put your life into the hands of these putz’s

I got the car back this morning and everything seems to be OK. Time will tell.

Problem was twofold. 1) the MAP sensor was out (?) Took them 2 days to get a new one. 2.)When they tried to connect it with Onstar that's when the 2d problem arose. Seems Onstar wasn't aware that the CT6 with Supercruise came with a 3 year connection(or so they said). They kept telling the Caddy folks it was a 6 month trial. Well, between OnStar, Cadillac Tech Support and the dealership they finally got it worked out. Worked very well on the way home, so we will see. BTW, they gave me an XTS as a loaner. Didn't like it one bit. It was unforgettable (for me); CUE was very confusing and the seats were hard as an stool. I could never get comfortable in the car. When I got in mine, it was like putting on a nicely worn pair of sneakers.

No issues that I can think of on 13k miles at least 10k on SC only.
Lots of tips and tricks to consider.
Could be glasses or the road or hw issue
If you get the sc icon the car is good and it a driver issue like glasses or the camera cannot see you.
If you don’t get a sc ion on a known SC road it’s a car issue.
Feel free to provide more info it should work very well.

So does super cruise work if you have sun glasses on?

 

[ROADRUNNER2]

Yes it does.

 

[04fxdwgi]

Yes it does, but I have found that occasionally, when the sun is to the left rear of car and shining in on the dash just right, it can blind the camera at times and cause the SC to cut out, with a warning of course.

There are also some roads where the SC won't allow engagement for what ever reason. Not every road is 100% compatible w/ the SC, even if it is a divided highway.

The SC, in my opinion, is not completely matured. But it is well on it's way. Kind of like a "beta version" if you will, and must be considered not yet perfected. Us early adapters are like lab mice (or crash test dummies) on this one and must maintain situational awareness, accordingly. And be willing to work through the shortcomings with an open mind.

It will get better with age and upgrades, if the SC keeps being available. Don't be surprised if it is completely superseded when the next generation appears after all the lessons learned on this version are learned and fine tuned.

Level 3 autominous driving is 5-10 years away in the US. I ain't gonna be around for it; at least behind the wheel.

Fully automatous driving will never be for me. Bad enough having a human driving while I am in the passenger seat.
Having your automaton getting blinded by the sun is a rolling disaster waiting to happen.
Movie fiction IMO

Having fully autonomous driving in a single controlled lane may be possible, but having it in mainstream traffic, ummmm no!

 

[carter's_sts]

Haven't you heard, you're just supposed to believe. All non-believers will be rounded up and put in reeducation camps where you must drive an obstical course all day until you relent. Then you will be issued a one time voucher to summon a self driving car to take you home as they tow away your personal car and send to the crusher because it's been deemed too dangerous to the self driving car fleet run by the department of transportation.

 

[ccclarke]

Because current semi-autonomous vehicle sensor systems rely too heavily on cameras, they are ineffective in inclement weather. Roads need to be upgraded with electronic marker systems (smart roads) to solve this. Once that type of infrastructure is in place, fully-autonomous vehicles will happen. The biggest safety obstacle remaining will be manual drivers.

At that point, manual driving will be made prohibitively expensive through high insurance premiums to force drivers into cars that drive themselves and justified by lower highway fatalities (for our own good). Fully autonomous driving is a long way off.
