Lol I haven’t had a vehicle that hasn’t had the check engine light on in twenty years, it’s usually something like an evap leak that’s pretty safe to ignore. But yeah, a code reader is a good call, you can get Bluetooth ones that send a readout to your phone, so you can ignore it and hope for the best, but in style.

This was the code causing my check engine light to go off, replaced the evap canister but the light stayed on. Went away after I got the battery replaced for unrelated reasons, so I would have saved some time and money if I had ignored it instead of bothering trying to fix it.
While disconnecting the battery for a while can sometimes clear out the codes, evap lights usually won’t clear themselves after the issue is fixed for usually 100 or so miles and a certain number of engine on\off cycles.
Get a 20$ code reader, then see what the light is on for. Then go from there to see if you should fix it or not. Some GM vehicles you can read the code from the car.
All my Cadillacs had this option, which was good because there was always something wrong with them. Once they stopped building boats, I stopped being able to fit in them. 2005 was the last of the true DeVille’s
