I’ve had my G (2006 automatic coupe) for a few months now and it’s been super unreliable. after not using the car for about a day it dies, and it’s even died in the middle of the street multiple times. I have gotten the battery tested a few times all saying the battery is fine and the only thing that ever popped up on the code reader was the camshaft position sensor bank 2 which I replaced. I’m still having these issues which led me to think it’s either a parasitic draw or the crankshaft sensor let me know if you have any other ideas of what it could be…

 

Pull the fuse for the stereo and amp, that's the primary culprit for parasitic draw.

However I'm betting your battery is toast, did they test your battery with a handheld meter or did they wheel out a big cart. If they didn't bring the bigger cart tester (load bank tester) then all they checked was your battery voltage which doesn't mean ****. Gotta load test a battery to see if it's actually good or not.

This has nothing to do with your car stalling in the road while driving though, that's a separate issue. Start with inspecting the plugs, check for vacuum leaks, clean the MAF, etc. Basic maintenance stuff.

Did you replace the cam sensor with a Hitachi or Genuine OEM Nissan parts? If not then it could definitely still be the problem these cars are notorious for not playing nice with any aftermarket sensors.

I would put an OBD2 reader on it again and check for hidden codes.
