C8 problems

The brakes on my 2020 Z51 squall loudly when stopping at low speed. The dealer said that was normal. I changed the dusty OEM pads to Carbotech low dust pads and turned the rotors. The new brakes squall, too! Is the dealer right that squalling is normal? It sure is embarrassing to pull up to an intersection where the brake noise is more noticeable than the Corvette. Any comments or suggestions?

Anyone else get a P2855 code?
Just got the CEL on (1200 miles), with P0700 (transmission control request to turn on CEL) and P2855 (Manufacturer Defined). I read someone else got these codes and took it to the dealer, but dealer just reset the codes with a no fault found. If it wasn't for Covid, I would take it to the dealer, but if its not an issue, it should reset itself eventually. Anyone else get the P2855 code or know what it means?

I have the same issue with my 2020. GM has a service bulletin on the problem. (Bulletin No.: 20-NA-091) No resolution except keep resetting

I used the outside mirror tilt-down feature in my C7 for parking when the car was put into reverse. There was a bug where the mirrors sometimes wouldn't return to their proper position when the selector was put back into drive. The bug was never corrected the entire time I owned the car.

Dash adjustment
Happy to report that the dealer was able to adjust my left dash / speaker cover.
The dealer was able to adjust, there is two screws apparently. Hard to get at.

My 2020 Z51 does not make any noise with OEM pads. (2800 mi) Even the brake dust problem that others have commented on has not been more than a normal sports car IMO.

not closing correctly. I can see a gap around the outside and inside of the roof. Any remedy before I take it to the dealer. It would be a great help. Thanks

Car COMPLETELY DEAD after update in just 4 hours! Says "failed update" on the screen. To get out of the car I had to use the emergency handle. Not even enough power to unlock the door. I drove it not more than 4 hours earlier. How the hell can a fully charged battery be DEAD in just 4 hours?
This really stinks. I'm sorry but I hope someone gets fired for this. Completely unacceptable. Its going into the dealer tomorrow morning to get 2 improperly cast rims replaced and see if they can fix my radio, which I know will take weeks. They already said the dash has to come out and Chevy has to approve it first.
I open the My Chey app -- it fails to open at all. Just gives me a white screen.
And GM really thinks we want all electric cars with more computers and more software?
I'm beginning to lose faith in this car...

You might want to "naively" ask your dealer, as well as Chev Concierge, to explain to you Lemon Laws.
As well, invoice Chev a reasonable amount for your time and out-of pocket expenses. The amount per hour depends upon your present income. Be prepared to send the same invoice to your dealer at the first sign he is less than 100 % supportive of your claim for loss of use of a big investment. Keep in mind: your dealer is an agent of Chev: he works for them, and is the one who sold you a troubled product.
Further, keep close records on how many days your car has been out of service, and demand to your dealer that your warranty be extended by that amount of days, or more. My dealer initially refused to lift a finger to help me extend my warranty for 1.5 months of lost use. Without going into detail, let's just say at the end of the day my warranty was extended by 1 year, and to 75,000 miles instead of 36,000. Maybe the dealer suddenly remembered the power of social media...who knows?
