Before this issue happen, I gave a someone a jump start for about 20 minutes. 5 minutes after that I drove to the store and went home to park the car. I was in the house about 10 minutes, and I came outside to start my car, that's when I notice my car won't start. The dash board light was on, the highlights were on. No Radio or navigation came on. I couldn't open the doors or the trunk unless I use the mechanical key. I ask a friend for a jump start, but to no avail nothing work. The last time I had this problem I was able to jump start and the car started up fine. But this time is just the opposite. Is a 2009 G37. Any suggestions I would appreciate the help on this.

 

If you have the original battery on a 09 replace it

What he said ^

 

I had to change the battery in my 09 last week it just gave up. Make sure your alternator is good before you change the battery though.

 

Thanks guys I check up on that.

 

I changed the battery and it worked fine. Thanks
