Just wanted to toss in my $0.10 here. Ran into the same issues - clock not resetting the whole day yesterday despite repeated drives and the Bolt being connected to AT&T (my phone carrier is AT&T as well, so no issues with signal). Also tried resetting it manually then put it back on Auto - no bueno. Eventually, I just forgot about it and trusted that it would fix itself at some point. This morning, on startup, the time was accurately reflected. Problem fixed. Thank you, Bolt. 2017 Premier with the software update installed (14.5.0).

me too // my 2017 bolt never adjusted for DST / it was set to AUTO had to change to manual to turn it back 1 hour

I'm going on 2 days of the Bolt not adjusting to DST (living in SF Bay Area). Seriously? How in the world could GM implement a clock that doesn't update to DST. They know everything about me already as I get the monthly reports on 'quality' of my driving.

I don't remember this problem last year but perhaps didn't pay attention. I understand that it should go away in time, but it's quite distracting to have the wrong time.

2019 Bolt - The time still won't auto adjust after 36 hours.

Has anybody gotten a definitive answer on what is going on here? I can access the car through the myChevrolet app even though I don't have a payed plan. I can use car-play. How in the world in this age can a car not get the time correct? There are so many ways it could get the accurate time but limits it to just through a cell connection.

I had to go to manual too. This wasn't a problem last year that I remember. ???

I noticed on the Sunday morning after the "fall back" that mine had not changed when I drove off. I was going through the settings (on "auto" set via cell network) and had resigned myself that I would reset it manually the next time I stopped the car. A few minutes of driving later I noticed that the time had corrected itself. It was kind of spooky, but in a nice way.

Questions:
Do you have an OnStar account?
Do you have an account with a cell provider that uses the vehicle phone (I don't mean a personal cell phone).
Do you have a data plan for the vehicle?

I have none of the above and my clock does not seem to want to update automatically (it's set to auto via cell network).

 

[ekutter]

Yesterday afternoon I tried setting my clock back to "auto" and it actually stayed on the correct time (I had manually adjusted it). Before it would immediately revert to the wrong time. So there is hope. Still crazy that it takes over two days to adjust.

I have none of that stuff either.

Thanks, that pretty much kills my idea that OnStar is the reason.

There might be something to this. Around the same time the clock started misbehaving, the shifter failed. (You can scan this site for the intermittent issues with the Bolt shifter.)
Possible root causes are then:

1) Clock resets to 12pm ... caused by loose positive terminal connector on 12V battery (likely to disconnect as temperature falls and rises overnight)
2) Clock does not auto-set from cellular network ... caused by Chevy Service not reactivating free OnStar subscription when changing out the radio (assumes you need at least a Basic OnStar subscription for auto-set to work. It's hard to prove if this assumption is true until 5 years have passed since GM started selling Bolts.)

As the original poster I want to declare that the problem is finally fixed (after 8 months). The original problem must have been the loose battery cable. The secondary problem (no automatic time corrections) was caused by Chevy Service not activating the free OnStar service after replacing the radio.

In the end, Chevy unnecessarily replaced the radio twice and the window regulator once when all they really needed to do was put the car on a diagnostic overnight and discover that the battery cable was loose and regularly dropping 12V power to the vehicle. Don't they have a diagnostic error code for 12V battery temporarily disconnected? And wouldn't the service tech disconnect the 12V battery as part of the radio replacement procedure? If he did he didn't tighten the connector when he was done.

Regarding the window regulator, that seems to be one of the few systems in the car that needs a manual reset after a 12V power failure.

Wow... For lack of a nail........ I still have random weird clock times tho - there's one special part of town where the clock just loses it - jumps forward backward, even sideways. Must be related to the cell signal there, but geeze, my smart phone never does this [it's on Verizon not ATT but still...]. And it happens occasionally in other locations where cell sigs are not robust.

It's been said before and it'll be said again: for hybrid and electric vehicles that rely on a 12V auxiliary battery, if you're having weird problems the battery is the first thing to check.

Argh. Another software glitch. And I did not see anyone else reporting it.

The cycle goes like this:

1. Clock is wrong
2. I manually set it to correct time and date
3. Next time I get in the car the time is wrong again (by hours sometimes)

And this is not a time zone issue because the minutes don't match the correct time either.

I took it to the dealer and they told me there is nothing they can do because "the time is controlled by the OnStar satellite". I asked, then, why it had a screen for setting the time. The reply was that it doesn't do anything useful because the time is controlled by OnStar.
My 2015 Chevy equinox is doing the same thing.
Can it be? And why did OnStar send my car, and only my car, the wrong time? It sends time to all GM vehicles, right?

I kind of think it may have sent a time correction factor like (run 1.2x faster than the electronic clock onboard the vehicle) such that it is either running way faster than it should or way slower.
I'll try to track that.

My clock keeps time after I reset until I shut my engine off.

Same here, gets frustrating.

Clock gets its time from the ATT cell signal. Onstar satellite is pure GM BS. OnStar is ATT cell only.
When the ATT cell signal is there but weak, the clock time set data gets corrupted, and the clock SW is too stupid to realize the data are invalid.

 

[EV Fan]

If you go into the setting menu for the clock, there should be an "auto set" option. Try turning the option off and then setting the time. I remember some problems with clocks not changing during daylight savings time, and this was the workaround.

MY CHEVY SPARK DOES THIS TOO!!
