Out of nowhere my abs, brake and vdc and slip lights are on. 03 350z. any ideas what it could be? thanks

 

Yep check your brake fluid if it's getting low it trips those lights to tell you to check your brakes... And it'll trip those light even before the fluid is to the min. line, specially when the fluid is still cold... So add fluid back up to the max line and see if they go away...

 

+1 Yep, check your brake fluid then check your pads. If not one of those easy fixes, it could be that the ABS system has failed.

 

You need a new ABS/VDC computer.
