My clock wont work either
 

Battery went dead. Everything came back with recharge EXCEPT THE CLOCK. Time buttons wont work and time block blank.

A little more detail about the car wouldn't hurt. Model year and whether or not it has the navigation unit. Info. might or might not help.

Seems to be a common problem since sometime in December 2018. Some seem to think it has something to do with a satellite reboot cycle and may come back after April 6, 2019. Based on some Forum posts it happens to the C-6 from 2005 to 2010 or 2011. Pretty strange, I changed my battery and experienced the same thing. I guess we will just have to wait and see if our clocks come back.:toetap:

April 6th is just a few days away now. It will be interesting to see if these clock issues resolve themselves later this week. Please keep us posted if you have a car that is impacted by this and let us know if it starts working again.

You're a member of a big club!

The battery died in my 2007 about a month ago. After replacing it, all I've had to do is re-register the windows. I had no problems with the clock before or after changing the battery. My car doesn't appear to be affected even though it was assembled in the first week of August 2006, right in the middle of the range of time that folks are reporting problems.

2010-ZR1, clock gone, waiting till the 6th, other then that the system all works perfect.

Five more days and we will see what happens.

Do you have NAV? Only affects vehicles that get their clock from the GPS satellites.

If your clock still isn't working after today, please post year model of your car here.

:lurk:

still no clock
 

2007 base 3lt. No clock and GPS with slash thru square box

Simply changing out the battery in February didn't deprive Red of power long enough. Friday the battery was disconnected all day while the supercharger went through its 100,000 maintenance. When I drove out of the shop on April 5, I noticed I no longer had a clock. It did not re-appear on April 6. Curiously, the NAV worked perfectly and guided me home from NYC to StL no problem.

2007 C6 Conv 3LT. It came off the assembly line at BG the first week of August 2006.

CLOCK IS BACK !!! Saturday April 5th at about 10:45 AM it suddenly reappeared on my 2007. I guess the April date rumor was true.:thumbs:.

Hmmm
How long did you drive before it came back?

I will fire mine up see what happens.

I was driving to a car show about 85 miles north for about 45 miles and looked down and there it was. Still don't have the "INFO" button illuminated on the screen. Both the clock and Info button went off at the same time but only the clock came back on. Does anyone know what is up with the Info button? I did have to re-set the clock time but noticed that the date info also popped up showing December 31, 2000. What's with that? I have not tried to reset the date function yet.

Check out a brand new post on Corvette Action Center. I just experienced the same problem. Did a bunch of research and I think I found a cause (USAF) but no cure.

Well, we're going on April 8th and NADA!

Us Cadillac owners with Nav are having the same issue, I jumped on your forum hoping you guys would have the answer.:(
