C8 problems

That's a pretty weird thing to do though, but in any case it should have done it a month ago when I first plugged it in. So kinda odd it decided to stop recognizing things just now, maybe it accidentally attempted to read one of the system files and just got into an error loop, or thought one of the directories were a playlist and just moved in there but refused to move out? (Which again would be weird because I didn't touch anything related to music on the drive over while it was working)

An actual problem I did run into today.
My C8 seems to have corrupted my USB drive I use for music. Randomly it stopped recognizing the files on the USB last night despite not having touched it in days.
It wasn't anything major, but the only thing I had on there were .mp3 files, when I ran a basic repair on it however it brought up a bunch of android system directories on the USB making me think that the car was attempting to write to the USB or was creating system folders during it's indexing of the songs and was probably just touching folders/files while doing so for some reason. I probably should have saved it off for troubleshooting sake, but I didn't see anything that was particularly note worthy, just mostly empty directories and a few files, so I just deleted the files and the repairs seems to have worked.
However it's still a bit of a weird issue. Anyone else run into that?

Tried to read the USB-C thumbdrive on my PC and it was unreadable. I reformatted it and it was still working. At this point I switched to using a CarPlay based AI box.
Really sucks because GM is now saying they will remove all AndroidAuto and CarPlay integration. How long before a "experience boosting" OTA update removes these features from existing cars?
I don't buy their excuse because I used a WIRED connection and there is never any hiccups, latency or issues. I definitely don't pay for their Onstar data plan and don't pay for their infotainment center based GPS maps though. I bet that has a lot more to do with their decision.
BYE BYE INTEGRATION!

Like the DCT issues a count of what you describe would come up with a statistically inaccurate result. I've never heard any howling noise coming from the rear of my 2021 after 2+ years of ownership.

There's DI noises, exhaust valve noises, sometimes noises from a problem with the eLSD (appears to be super rare), sometimes noises due to a broken valve spring, etc.
Howling from the rear end??? Did it sound somewhat like an internet troll being left behind at the light?

I am calling bullshit actually on this one. I have been following the C8 since it was first unveiled, and got mine in June of 2021, and active on the problems threads. "Howling" rear ends... OK. YEP. GOTCHA!

There's a lot of tire noise. There's a droning exhaust noise that can be much worse with some aftermarket exhaust systems, etc.
Search the forum for "howling" and you will see very little from anyone. There's a post from bondojon though.
The closest thing I could think would be the diff noise that some people have experienced. Usually described as a whine vs a howl.

Not saying he doesn't have a weird howling sound from his car, anything is possible, but I haven't heard of a huge number of people complaining about this issue that it would warrant trying to analyze the number of reports.
I think the best advice has already been delivered, take it to the dealer. Do a check ride with a tech.

I have the non-Z51 and think the tire noise is worse than my C7. I had the Michelin Cup tires on my C7 but I replaced them with some Michelin Pilot AS3+ tires and it virtually eliminated the noise. It also all but eliminated the Ackerman effect. When my all-seasons wear out on the C8 I'm going to have to research and buy a better Michelin all season tire to see if it will eliminate the tire noise.

There are many examples of problems on the forums with noises coming from the rear end. I have a new 23 and I can hear a howling coming from my rear end. I’ve been an automotive mechanic for many years and I know what a rear end (differential) sound.
I just read a reply from a person who bought a new C8. As he was driving it out of the dealership he heard the howling noise from the differential. He said he was going to turn around and go back to the dealership but decided not to because of the other problems he hear about with noise from the rear end. Just do a search. You’ll find this problem on many C8. Mine included. I brought it to the dealer and he said it was normal. That’s what they’re telling everyone else.

Put a recording device in the back of the car and see if you can grab some samples of the sound to share.
I hear a lot of noises back there, but not howling.

I've seen a few posts about a rear end whine at certain speeds, but not a howl. It's a very faint whine. Mine does it between around 60 and 62 mph. Goes away above 62 and below 60. Again, very faint and not worried about it.

here is a recording of the sound I was getting. You can hear it when the vehicle is going a steady speed.

Could Be DCT
Early in my ownership experience my car (2022) tripped a CEL. It was DCT related, though my car behaved normally.
The light disappeared after a few cycles and the stored codes were pulled by my nearby Dealer/Service Dept. In an attempt to diagnose GM Technology had my local Tech call/ask me a few questions relative to the cars behavior. One thing he asked/they wanted to know was if I had a notable WHINE?? answer was no, not at all. They went on to explain that they’ve seen a notable whine in connection with abnormally high pressure (in the DCT, the pumps that supply fluid). Again I didn’t have this particular issue but found it interesting and memorable that they would mention… FWIW

The 2023 C8 tire noise (have 14K miles now) started to get louder around ~10K miles.
And it definitely seems louder than my C7 ever did.
Obviously different car/non-Z51/Z51 and different tires, but still surprising.
I've heard that run flat tires tend to get louder as they age but on the C8 it definitely seems louder than my previous C7.
Unclear how much Z51 would contribute here (if any) to straight continuous driving tire noise.
