I stalled my g35 and when trying to restart it, there is a complete loss of power, no lights work, the car doesnt turn on when you flip the key, none of the electronics work. I probably had to wait close to 30 minutes for it to get its power back. Does anyone have any idea as to what it could be?

 

Check your battery cables, sounds like one is loose, that's the only reason you would lose ALL power. This car doesn't use a main relay like Honda does. It uses an IPDM which would still have power on all accessory systems. If you lost ALL power it's because the battery was disconnected.

 

UPDATE: So I just got the car on sunday and the guy we bought it from said the only problem it has was that at idle the rpms were low and he'd have to flutter the gas to make sure it doesn't stall. He said the the lights flicker in the car (im assuming he's talking about the gauge cluster). He also said that this problem had only happened to him 6 times in the last 2 years or so. I've had the car stall on me twice today and lose all power. The first time I stalled it due to being a rookie stick driver at a stop sign and I had to sit there for over 30 minutes trying to get some sign of life out of my car. It was only until my dad brought his truck and attached a strap to the back of my car and started pulling me backwards in neutral, that my cars gauge cluster just lit up and everything came back on (I had the key in the on position while he was pulling me) and I was able to drive it back home then. The second time was not my fault at all, I was parked at a store and I started my car and let it run for about 30 seconds letting it warm and it just stalled and shut off all the electronics again. The only thing different about this time though is when I would flip the key back and forth to get some sign of life, I saw the "PASS AIR BAG OFF" light come on for a split second and then disappear every time the key went to the on position. I am not sure if it was doing the same thing the first time it stalled. The negative terminal was pretty easy to undo the first time it stalled so we made sure to tighten it as much as possible without feeling like we'll break it. The second time I stalled I tried wiggling the negative end and it just starts spinning around the terminal and did not seem tight at all. I will look more at the battery tomorrow and also try to clean off all grounds just in case. Any advice or help is greatly appreciated!

 

Yeah sounds like you might actually have a broken post on the battery itself, if it's just not clamping the post enough then that's an easy fix. You definitely should not be able to move the battery lug AT ALL when it's bolted to the battery post.

 

I wouldn't think the actual post itself is bad. I cleaned the posts and we got a new ground connection so it holds tight, but now when I went to go turn the ac on in my car while driving my interior lights and gauges started flickering and it felt like the engine was losing power or just died for a second so I turned off the ac real quick and it stopped but then when I got to the stop sign right in front of me it stalled and completely lost electrical power. But I was on a hill so I put it in neutral and let it roll back and off the road out of people's way but that didn't do anything right away. I just kept the key in the on position and it came back to life within like 5-10 minutes after rolling it backwards. I have gotten my engine scanned after that happened and it came up with the code C1109 (Battery voltage abnormal). Online it says possible causes could be a faulty ABS module actuator, ABS module harness is open or shorted, ABS module circuit poor electrical connection, blown ABS module fuse, or low battery voltage. Our guess is the low battery voltage but we're going to load test it today and see how it performs and I'll keep you updated. But if anyone could explain the other possible causes if need be that would be great. Any insight is appreciated.

 

That sounds exactly like a bad battery or bad/corroded cables.
