Usually, when starting my car, as soon as I turn the key all the way around, the car instantly starts revving and then springs to life.
For some reason, today, when starting my car. I turned the key in the ignition and nothing happened. My dashboard's lights turned on, however, no sputtering or no audio indication that my car was doing anything. I tried this multiple times, but still nothing.
On my final attempt, I turned the key all the way -- but held it there. For 5 or so seconds, the car did nothing, but then suddenly it started up like it usually would.
I'm aware that this has likely something to do with my battery going bad, but what I'm confused about is the specific nature of this event. In my experience, either the car will sputter for a bit or just wont start up whatsoever. Not this weird delay. Really, I'm just curious if there's anything else I should be concerned about other than my battery.
Thank you! My car is a 2010 Camaro with quite a good number of miles on it.
Edit: Thank you guys for all your responses. Seriously, you guys are absolute geniuses!
