I restarted my car after driving about 90 miles. Everything except the controls for cruise control have stopped working. Interestingly my steering wheel is still heating but the lighted button is off and I can not turn off the heating. The volume buttons fav buttons and menu controls to change the speedometer display are all inoperative. Could there be something as simple as a fuse? I will be calling the dealer for service on Monday. Right now the car is drive able and there are no error messages.

All functions are working normally after turning off for fifteen minutes and restarting. I guess it's like a cell phone. Reboot and cross your fingers that it won't happen again.

That's usually the case with most things these days, reboot/restart them and there's a good chance an issue will clear up. But you do have a point about the fuse, apparently those can go at any time, even on new vehicles.

There is a software update (not official yet) for steering wheel control functions inop.
It's a USB file upload for the (instrument panel) IP and it should resolve this problem.
Mine stopped working intermittently and after updating the IP, it has not returned.

drdiesel1,

Perhaps I have missed it, but is there any background info or information on how software gets updated? By this I mean how is the operating system accessed and are files physically transferred (via USB, as you mention)? Thanks -

This has to be done by the dealer. They download the file to a USB thumbdrive and use it
to upload to the IP. No software update on this one.

I doubt it. I was talking with one of GM's infotainment specialist and he told me about it.
At that time there were no TSB's for it. I have not seen one, but, I did the update on my car
and have not had any problems since. I updated all my modules on the same day.

Are you wearing your seat belt ? L mode will not stop the car if the belt is not buckled.

good catch, i didn't buckle the belt because i was just doing a quick test. thanks for the info!

seems weird though, you'd think they'd want the car to stop if you weren't wearing a belt.

It's part of the safety systems and has other functions tied into it.

They don't want you stopping in L, then forgetting to power down or placing it in park before getting out.

When you stop in L Mode and unlatch the seat belt the car automatically activates the parking brake. IIRC, it will also apply the parking brake and put it in park if you open the door.

Trained my brain to think of L stopping/slowing as a convenience. It's fun to drive that way but if you see brake lights or some other reason to slow down one still needs to keep in mind the reaction time to go from 'gas' to brake pedal.

As to software glitches; I have had a couple of occasions where I could not get the infotainment system out of On Star and the volume was full blast. I had to restart the car. Another case when my phone would not connect and a restart fixed that.

Does anyone else notice that if you put the car in R before fully booting up the lines on the backup camera won't come on the screen? Or has anyone had the back up camera come on in a smaller window when putting in R before full boot up?

I've had the first scenario happen multiple times. Sometimes, it recovers after a moment and the gridlines appear after a few seconds. Other times, you don't ever see them appear.

If you catch the system while it's booting up and pop it into reverse, it's your fault.
You can't interrupt the systems boot up without paying the price...:nerd:
