Hi i have a 2003 G35 and i noticed yesterday that on the left taillight the LED's on the 3rd row aren't coming on. The first and second row light up fine.

Has this happened to anyone before and is there anything i can do to fix this or do i have to buy a whole new taillight?

This is the first I've heard about this...Not sure if you can replace individual bulb modules. I'd get the light housing off so you can see what needs to be done.

I wonder if there are multiple grounds for the tailights? Perhaps one or more is bad. You may want to check with Infiniti parts department and or check the FSM?

ok new information this morning when i checked the tail lights again all the led's were on.... however when i reached back home and checked them again the third row was back off.

Anyone know what can be causing this? And does this mean i don't need to buy a new tail light?

Poor or loose connections, or poor ground? LED's or bulbs are usually not intermittant?

You probably don't need a new tail light. You probably will need the electrical schemetic diagram as well as all the locations of all plugs, connectors, wire colors, and any possible relays feeding the 12v coming from the light switch to the LED's as well as the ground locations. You will also need a digital voltmeter. (There could also be 12v at the lights and the light switch sends a ground)? If that were the case you could be missing the 12v on some of the LED's that don't light?Follow the FSM test procedure. It could be something simple that you might find or you may end up having to take it to the dealer. They'll have one of their top technicians that earn over $100k/yr find your problem.

Have your credit card ready $$$

Good luck and let us know how you make out.
