I’ve had my car in winter storage for about a month and went out yesterday to start it up. The battery was stone dead. So I read the manual and think I did everything correctly. Now the CEL is on and the traction control stays off all the time. When I first started it yesterday after charging it, I had all kinds of problems. The active exhaust didn’t work, traction control, CEL. I was hoping it get in the car tonight and it would’ve learned the battery by now. The exhaust works now but still a number of electrical issues. The thing is, and crucify me if you must, but I don’t remember locking the doors when I let it sit overnight. Could that be it? Anyone else dealt with this before?
