Replacing battery and getting codes to reset...
Got my 07 from a dealer in St. Louis and had them replace battery before they shipped here in Feb. I finally got the title transferred here in Ohio the other day after they reopened from the Covid crap. It also required me to get an echeck before I can get plates. Went there and was told it is not showing codes and asked if any work had been done or battery replaced. When I told them the battery was replaced, they told me to go drive it to get codes back....sigh
I already had driven it a little over a hundred miles so was scratching my head on how friggin' long it takes to get codes back. Any thoughts or experiences? I called the Chevy service dept and was told it could be one hundred miles or five hundred! Is he correct?

Do a Google search on Chevrolet (General Motors) drive cycle. It will tell you the specific parameters you must meet/drive to clear the OBDII requirements such as EVAP.

I was always under the impression that several Cold Starts were required, but the above does not indicate that.

And scary that the Chevy service department had no clue.

I have the exact problem on my new to me- 6,000 mile 2013 427 anniversary model.No codes but a problem with the EVAP. I was told to keep driving it. I bought it from an exotic car place and had it shipped from Michigan.The dealer at the showroom owner put in a new battery since it sat inside for 2 months. I drove about 100 miles and no luck yet.

SOB......I did the GM list and additional miles to establish the damn puter....and it failed again at Echeck! I am so pissed. Over half a tank of gas and over 200 miles....nada. It has 13k on the vette so not like it is a 200k junker.
Whatever engineer came up with this system is truly an idiot and Ohio....your Echeck is truly a place I would love to burn down! I hate wasting money and time on such stupid chit!

I had the same problem. I replaced the battery right before I had to get a smog check(i'm in CA). My vette wouldn't pass smog, so I was told to drive my car for a couple of days and go back. So I drove the car for 5 days, drove about 25 miles each day, regular driving (60-75 mph). I went back and still didn't pass. My O2 sensors were not working, I was getting a code. So next morning, I drove about 100 miles at a steady speed (50-55 mph), I went back and it passed. So you might want to try that. Good luck!!!!!

Good luck! I now have 250 miles on mine with two codes still not reset. I got a 30 day extension from Motor Vehicle. I currently have 9 vehicles and do not enjoy putting unnecessary miles on a vehicle for absolute nonsense. If your out enjoying yourself that’s your business, but just putting wasted miles waiting for codes to reset is very frustrating, and unnecessary.

The EVAP monitor is one of the hardest to reset. The fuel level must be between 15-85% and the computer needs to see a cold start, hot start, consistent ~50 mph for a few miles, along with a few other scenarios I can't remember. You can "force" it to run with a Tech II, otherwise a few days to a week of normal driving should set it.
