My wife observed something strange the other day with our Bolt. Not sure if we'll ever see this again, but thought I'd share.

When she got in the car and pressed the power button the loading screen was stuck for nearly a minute as shown in the photo. She pushed the power button to power off the car and then again to try and start the car but the same loading screen was stuck again. Once she got out of the car and got back in the car started up just fine. The weather was in the mid 60's.

Would there have been another thing to try if this comes up again? Has anyone experienced this in another EV?

That's odd, makes me believe that it was a problem between the key fob and the car since it worked after she got in and out. But it could be a case of "third time's the charm"...

The main touch screen was stuck for 5 minutes or so. The back up camera would not come on, Apple car play. Nothing. Turned the car off and on a few times to reboot. Finally screen came on.

I've noticed a similiar problem with the display when using favorite shifters on steering wheel. At one point, the display got stuck. After exiting the car and letting the car reset, the problem fixed itself.

Sounds like a recurring problem if two members here are seeing the same thing. Best thing to do is record it occurring again and show it to your dealership. Sometimes you can't recreate it when needed.

I would definitely bring it to the attention of your dealers so that you at least have it on file that it happened. That way if it happens again they may be able to do something about it. A software update may need to be in order.

Thank you everyone for the feedback. Sharing this with the dealer to get it on record is a great idea.

Just guessing here- We have two people that have stuck screens and the solution seems to be getting out of the car and back in again. Rather than a problem with the key fob, I suspect the user's cellphone. When the car makes the bluetooth connection to the phone it may have an issue with something on the phone, or what the phone app is relating to the car.

Next time somebody has a frozen screen, try turning off the phone, or at least the bluetooth and see if that helps. Sadly, the reality is this car needs a more powerful computer to run than cars in the past and now, do to consumer demand, that same computer has to interface with a multitude of other computers that can have thousands of different bits of software installed by users. A potential conflict could be a computer programmer's nightmare to trouble shoot.

I just hope we don't have screens going down and computer seizures while we're driving! :eek:

My impression is that the speedometer screen is driven by a system that's independent of the infotainment system and I imagine that it's a lot less likely to suffer these kinds of issues.

Well, in the OP, the problem was that the speedometer screen wouldn't boot up until they left the car. I'm not so sure there are two independent computers. It would be good to know for sure.

This did happen to me. As I drove my new Bolt off the dealer's lot, the main infotainment screen went black and began rebooting as if I had just started the car. I think both displays went dark, but don't recall for sure. Driving functions did not seem to be affected, but it made me nervous and I u-turned back onto the lot to ask about it (the dealer unsurprisingly had no useful information). You may be right about the computer/phone interface at least in this case - at the time I was trying (and failing) to make a call thru Android Auto.

Over 1500 miles on the car now, and that has never happened again.

Ah, you're right - that's a bit disconcerting.

Although I notice that the screen was still on and it still had a speed readout. It may be that the area of the screen that said "loading" was an area in which infotainment data is displayed (e.g., current radio station) and the infotainment system hadn't yet supplied that information.

Something that is consistent with phil0909 story is that my wife plugs her phone in and uses Android Auto. I like the theory right now that it could have been related to the phone connection. I will share if it happens again and we'll try troubleshooting at the phone connection rather than musical chairs.

My display goes blank too

I purchased the Bolt last week. Once while driving home for the first time and again today, the infotainment center screen went blank when the power on button was pushed. The screen behind the steering wheel said "loading". After what seems like several minutes, a brief message comes up too fast to read but seemed to say something like "error corrected...". Then everything came back on and my music started playing.


I do not use a cell phone, nothing is paired. Since it did this on the way home after buying the car, I went right back to the dealer. Their service guy had no idea what it could be and made sure my "dimming" rheostat was turned all the way up so it doesn't dim in the dark. Yes, the car seems to drive OK but with a blank screen I pull over and await the system to "load" and reboot.


I called another dealer and told the service guy what happens. He said he would research the issue. Nothing heard so far. Since this thread exists I am surprised Chevy is not listening.

I'm sure they are, just don't expect a response on an internet forum. All the car companies found out years and years ago not to get stuck in the quagmire that can be an internet forum. GM is not likely to announce a technical service bulletin to their dealers until they actually have a fix. In this case, it is no doubt a software issue and not a hardware issue, so they have to reproduce the problem on their end, figure out why it's happening and then recode the OS. Then they can issue an update version and let all the dealers know about it.

I think a problem like this takes some time because it's intermittent, not an obvious mechanical failure and doesn't seem to effect all cars.

And I'll bet problems like this only get fixed after one of more dealers upload software logs, so don't be shy about taking the car in for a service incident to report a bug (so perhaps I won't have to)...

Manufacturers like Chevy are more likely to take notice of a problem like the black screen if dealerships are sending in reports about them. So there's no shame in bringing your car for a check up if anything looks funky.

Happened to me as well

Car is only two weeks old, 150 miles. Turned on with the "Bolt EV" screen, but that screen did not go away.
I tried a variety of buttons, to no effect. The DIC still worked, and the fan buttons worked. Pressing "Max"
made the fan and AC come on full blast. No other misbehavior...just the frozen screen.

After three or four minutes, while fiddling with the infotainment power and volume knobs yet again, the home
screen appeared. It behaved normally after that.

Weird. What process takes three or four minutes? Does Chevy push new firmware downloads at random times?
I too had my IPhone connected via Bluetooth (but not by cable). I did nothing different this time compared to
a drive 10 minutes earlier (or indeed every other time).

If it happens again, it's best to bring it in for a checkup. I don't think Chevy can push through firmware updates wireless if that's what you're wondering.
