I have a 2010 G37X Sedan...
I'm not sure if anyone has ever had this issue... But randomly my driver side headlight goes out. It's not just the low beam HID, it's also the high beam HID. When they work they work great, but randomly every few weeks or so the driver side goes out and then a few days later will work fine again.
I have checked all fuses associated with the lights on both sides and can't figure out what the issue is. Hope you guys can help!
Oh and all accessory lights and fog light on the drivers side still work even when this happens.

See page EXL 7 & EXL 35
You will need a voltmeter
Could be a poor ground or harness connection at best or a BCM and/or IDPM replacent at worst.
"PRECAUTIONS FOR TROUBLE DIAGNOSIS
Representative malfunction examples
are; "Light does not turn ON", "Light blinks", and "Brightness is inade-
quate." The cause often be the xenon bulb. Such malf
unctions, however, are occurred occasionally by HID
control unit malfunction or lamp case malfunction. S
pecify the malfunctioning part with diagnosis procedure.
• Never touch the harness, HID control
unit, the inside and metal part
of lamp when turning the head-
lamp ON or operating the light switch.
• Never work with wet hands.
• Never perform HID control unit
circuit diagnosis with a circui
t tester or an equivalent.
• Temporarily install the headlamp on the vehicle. Co
nnect the battery to the connector (vehicle side)
when checking ON/OFF status.
• Disconnect the battery negative terminal before di
sconnecting the lamp socket connector or the har-
• Check for fusing of the fusible
link(s), open around connector,
short, disconnection if the symptom
is caused by electric error.
• Turn the switch OFF once before turni
ng ON, if the ON/OFF is inoperative.
• The xenon bulb drops the amount of light, repeats blinking,
and illuminates in red if the bulb reaches the ser-
IPDM E/R activates the internal control circuit to perfo
rm the relay ON-OFF control according to the input sig-
nals from various sensors and the request signals re
ceived from control units via CAN communication.
