Over the last day or so I have noticed some yellow fluid dripping from right in the center of my 07 G35x. I parked on some fresh show to see what color it really was and its bright yellow (like the color of highlighter fluid). All the fluids levels are fine, so I took it straight to the dealer and they found nothing wrong...pressure tests on the brake lines and coolant system were ok.

I'm not worried about it, I'm just curious if anyone knows what this might be.

 

Have you tried smelling it? That's usually an easy way of determining what type of fluid it is. Once you know that, you can use process of elimination to figure where its coming from.

Oh, and don't eat the yellow snow!

 

maybe a cat went under your car and peed?

 

ha yes that is probably true.

 

Could be the condensation dripping out of the catalytic converter.
