Family, I am having a problem with a 2008 g37s coupe. This morning I went to start her up and I hit the button and nothing. I looked the trip odometer had reset itself to 0.0 and then it started. Then this evening its the same thing. I put my OBD scanner on the car and found not codes. I checked the battery, hoping to find a loose or corroded terminal and nothing. I am wondering if I have a battery that is showing signs that it is getting bad or what????

 

How old is the battery?

 

I bought the car last year, I looked at the battery and its a Smart Start, it appears to be have been changed, its an oreillys battery.
