1) with 2 miles on the odo, you need to know that ALL new C8's make a god awful burning smell for the first 1000 miles or so. This has been surmised to be oil coatings and materials in the heat blankets around the cats escaping. It smells like burning plastic, etc.
2) the LT2 engine is a DI engine and they normally make a lot of ticking / chattering noises which are the fuel injectors.
3) ESC should be unrelated to engine, that is a transmission issue. If you are having misfires, where did you get your gas? Make sure you are running 93 octane and from a "top tier" source.
4) on a new car, the last thing I would do is buy it and then put it on the shelf for a long time. You need to get through the break-in period and discover if you have any issues early on. Most failures in all things made by mankind happen either early on or much later due to wear and tear.
It wouldn't be a bad idea to have some sort of "New C8 Owner Sticky". Both items 1 & 2 had me slightly worried.
Also, if you have NPP, you'll get a sort of sneezing sound when your car goes from V8 to V4 mode.
I have not noticed any significant difference between having Recirculation On or Off, in the Climate Controls. It seems that even with Recirculation On, a lot of the outside air is still coming into the cabin; no help in blocking outside foul smells.
Does anyone else experience this issue?
had my c8 go into limp mode 18800 miles ran terrible thought it was some of the mods I had done and there was a real bad problem but I forgot that the ground cable broke the bolt on the connector and I had put a new bolt in but wasnt super tight repaired the ground cable runs perfect these cars are extremely finicky on voltage I mean my ground cable wasnt wobbling or anything I still had to pull to get it off put it did come off when pulled

Yes, i thought it was just me. It seems my car gets a ton of outside odors, fumes, smoke, exhaust, etc.
Here's one nobody else seems to have experienced, and it's become really annoying.
Randomly, after locking the car, the alarm goes off. I always get an OnStar notification telling me the doors or trunks are ajar. When I check, all is fine and closed properly. When the car is turned off, no warnings about open doors or frunk/trunk are shown. It always takes 20 minutes after the car is locked for the alarm to go off. Once the alarm has been shut off or times out, car's alarm will not trip again. I can keep it parked for days at a time, locked, with no problems. Then, whenever it's been driven and shut off, I'm at risk for the alarm going off again.
The other day, when it was parked in my garage, I opened and closed the trunk and frunk many times, opened and closed the doors, and locked and unlocked the car many times. No alarm. Then I went out for a ride, came back, and locked the car. Twenty minutes later the horn was going off again.
It's been to the dealer once, and they could not replicate the problem or find any codes. I took the car back home, locked it, and the alarm went off twenty minutes later. I took it back again on Monday and told them to keep it until they figure it out. No word yet.

The 20 minutes may be a tip off. From my observation, there are a number of "timeout timers" in the Chevrolet / GM vehicles. (We have a 2020 C8, a 2021 Tahoe and a 2021 GMC Acadia.)
"One of the newer GM safety features is Extended Parking, which automatically shuts off a vehicle’s engine after a certain period of time while the vehicle is parked. The goal of the feature is to reduce emissions and prevent potential carbon monoxide poisoning in an enclosed space. However, some owners might wish to disable Extended Parking, thereby preventing a GM vehicle from shutting off the engine when parked.The GM Extended Parking feature automatically shuts off the engine when the vehicle is parked for 20 minutes and the key fob is not present, or after an hour when the key fob is present.
Disabling the feature is accomplished by pressing and holding the engine/vehicle start button until the driver information center displays the message “automatic shutdown off.”
Obviously your situation is different in that you are not idling the vehicle. Yet, there is definitely a 20 minute timer in the vehicle software, so there may be a relation to your specific problem. I'd play around with disabling the "automatic shutdown" via the instructions above. Also search the web for other reports of 20 minute timers in the C8. There may be more.
And last, the "reset" by leaving the driver door open for > 90 seconds is always worth a try. (Search this thread if you are not familiar with it.)

FWIW.
Thank you very much for that information. I was not aware of a 20 minute timer on the car and have forwarded this information to my dealer.
I have tried the reset twice, and it did not have any effect.
With less than 300 miles on my new 2023 C8, I discovered an oil leak at the rear of the car. I just returned from my dealer where it was diagnosed as a leaking transmission case cover. I was advised NOT to drive the Vette until it is repaired. Parts (seals) are on order and no idea yet on how long it will take to have them delivered to the dealer. The Tech told me the exhaust has to be lowered to complete the repair. I've included a photo of the part in question. Has anybody else had this issue?

It's the first I have heard of that rear cover leaking. It was typically the pan seal, which lead to a re-design of the pan, or seals on the output shafts, or the dreaded porosity issue in the deep pocket in front of the valve body.
Quick! run out and buy a lottery ticket.

That's the same thing the Tech told me....he'd never seen one leak in that location. Maybe it's something new on the '23 models? I've heard of all the prior customary leak points, but this is a new one.
