So my car i just a year old now. And the battery went dead 2 days ago. Had roadside come out and replace the battery and everything was fine again. Nothing was left on in the car, just normal operation. Should I bring it into the dealership to get it checked out.
Also i had it serviced like 300 miles ago for service A.

 

Id bring it in. Your battery should last minimum 4 years. It's generally rated up to 8 years although mine only lasted about 6. But there maybe some component not shutting down that's killing your battery so fast. I wouldn't wait till it happens again.
