Ok so I have had the dreaded Front/R Solenoid problem for about a month now and I'm about to solve that issue. So I have the service engine light on as we speak.

The new problem just started happening randomly. While I drove the car anywhere it all of a sudden dies (electrically). Most of the time it kicks right back on. Once it didnt. I also noticed it will do it if you turn the lights on while driving in the daylight sometimes, or if you go under a bridge and they turn on with the auto feature. Also when I leave it, sometimes I come back and the car wont unlock with the remote and there is no power when I open the door. If I shut the drivers side door, sure enough the power comes on and the car will start right up like nothing is wrong. Battery is fine BTW.

Car Info: 2003 G35 Sedan Auto 93,000 miles - No Aftermarket engine parts. Clarion DVD touchscreen installed, small amp with a small 10" sub. Aftermarket Viper Alarm/Remote Installed from previous owner, but I told them to disconnect this.

Could this be my alternator going out on me? I have noticed a small squeal coing from the alternator area.

Any help would be great.

 

Don't think it's the alternator... either you have some loose wires or you need a new battery.

 

Possibly a loose ground? The battery is fairly new and it cranks with full power once the car door shuts and power is restored....so odd...

 

Yea, I think you may have solved your own problem. That would be my best guess.

 

Solved it. Ground terminal on the battery was loose. Literally pulled off without any effort. The last owner didnt seem to savvy so far...

How fun.
