My g just reach 30k today, whats the required maintence? i usually do the usual 5k oil and filter change and i recently change the tires...my friend told me to do a transmission and steering flush, is that required on 30k? thanks

It's advisable at 30K miles to have all fluids changed, trans..diff..radiator. After 30K miles I'd look closely at your drive belt. If you haven't replaced the cabin filter or intake filter now's a good time. I hope you're using synthetic oil since you wait 5K to change it. You can save a lot of $ by going to your local Nissan dealership since Infiniti charges 40% more....worked for me!

Steering fluid flush?
