my 09 G37 is stalling out every 2 weeks or so when starting it up. I have replaced the battery, had everything tested and it continues to shut off when initially turning the car on once in awhile.

any ideas? thanks

 

Also, I have had the dash lights (gas light, 8 & 9 rpm numbers) flicker, come on, shut off etc for the last 2 years or so which made me initially replace the original battery but does not seem to be the issue when replacing the battery for the 2nd time in two years.

 

I have the same issue for about a 1.5 years now and I'm on my 3rd battery. Just this week it started to act up again. The only thing the dealers say is that I left the car in the "on" position (i just laugh). I wish I new of a fix.

 

My did this for a while. Ended up changing out the dash cluster. No battery issues here.

 

It could be the alternator or the ECU not working properly to switch on the alternator.

This might help too:
