Any ideas where to start? i tried google search but nothing really came up for infiniti g35 sedan with this issue.

 

Sounds like you have a short somewhere. I had something similar happen to me with my old car. It ended up being a 2 prong bulb that popped but the dead connector landed on the good one (if that makes sense) and caused a short. Took a couple of hours to find since we didn't know what we were up against.

 

well for now, i just unplugged my reverse lights. i was getting aggravated with drivers behind me honking at me thinking im in reverse at redlights lol. when i get time i'll try to give it good look.
