My 2013 Camaro 2LS has been sitting in my garage without being driven daily for about a month now, maybe longer. I have only driven it in my driveway to move things around in my garage. The last time I've started it was December 28th and it ran perfectly fine (ran for about 1 minute and moved a few feet to make room in my garage).
Today was the first time in awhile it has been nice out, so I go to start it and I have a check engine light and a warning message saying "Service StabiliTrak". StabiliTrak looked to just be stability control, so I wanted to see if the engine would fire up; it did, but the engine ran pretty rough. I let it idle for a few seconds, 15 tops, and turned it off. I then tried to turn it back on and after 4 - 5 cranks (it usually takes 3) I decided to stop and not put too much strain on the starter. While trying to start it the second time the electronics and headlights were much dimmer while trying to start it and flashed quite a bit. I then used the built in battery voltage display while in accessory mode and it read pretty low, about 11 volts (I normally see this between 12.8 - 14.2 volts), but the lights and displays all appeared to be working. The only thing I noticed is that the oil was at the min fill line (maybe I have a leak?), but hopefully that wouldn't have caused any damage?
Also worth noting is that I live in Upstate New York where it has been between 10 - 30 degrees Fahrenheit for the majority of December.
To summarize:
- Vehicle has been sitting for about a month.
- Check engine light (I'm getting a reader tomorrow to get the code).
- "Service StabiliTrak" message.
- Low battery voltage (11 volts vs 12.8 - 14.2 volts normally).
- Low oil level (probably an unrelated leak).
- Vehicle started once, ran rough, and struggled to start afterwards.
Could this be due to a dying battery? Is there anything else I should check before trying to start it again to prevent worsening the situation?
