G37x Sedan Electrical issues
2009 G37x Sedan-occasionally upon start up, the car starts fine but the brake & ABS lights will light up and nothing else on the dash will work. No tach, no speedometer, no odometer, no gauges, and no AC, but the radio will work and the car runs fine. When this happens the car will not shut off no matter how many times you push the ignition button. It only turns off after holding the button in for about 10 seconds. I have shut the car off and restarted it multiple times to no avail. I tried just pushing start without using the brake to go into accessory mode first then start, this didn't work either. So I roll my windows down and go with nothing on the dash working and no AC. After a while, 30 minutes or an hour later it just suddenly clicks and everything returns to normal. Any ideas??

Update: So I fixed the issue. Unplugging the battery didn't do anything. I also replaced the fob battery... nothing.
Went through the fuse box next and found the 'elec parts (IGN)" fuse blew... so this controls the sensors for the speedo/rpm/fuel and the shifter. Like the video showed it had power just no sensor response. I'm guessing that also controls the trunk release because it works again. The check engine light did come on so I gotta clear that but the car is back to normal.
