Hey guys, I bought a 2011 g37x sedan from
Carvana in may of this year (i would suggest no one to do the same). I don’t know too
much about cars but I’ve dreamed about getting a g37x sedan for years and i have a lot of plans for this car. What is some suggested maintenance i should do and how often should i do it to keep my g in tip top shape.

 

looking great congrats

 

I'd start with all the fluids. Engine oil, brake fluid, power steering, coolant, rear diff fluid, etc... If you have service records its up to you, but I buy privately and always do this.
I also fixed the sunroof drain. Never had an issue with it, but I'd rather fix it before it starts leaking than after.
It never hurts to do an inspection either. Just look at everything and you might find that your pads are almost gone or your wipers are torn.
Also, listen to see if your cats rattle. Its a notorious problem and the next time I get some time I'm tackling it.

 

How many miles are on this G? It can help us make some suggestions, Concur on changing fluids and don't forget about doing a four wheel brake fluid flush using a high quality DOT 4 fluid.

 

I bought the car at 102k miles and it's at 112k now. So far I've gotten one oil change and I'm just now due for a second one. I haven't changed any other fluids but plan to do so.

 

Definitely add the heater line union to your list. Do not touch it until you ready as it will disintegrate.

My G37xS is about the same mileage as yours and I've done a brake fluid exchange (due to some fluid discoloration and a spongey brake pedal). Would definitely recommend also checking the rotors and brake pad thickness. I agree with AN1K, starting with fluids is always a good game plan. I'd recommend an oil change, front differential and rear differential exchange too, make sure the fluid used is API GL-5, viscosity SAE 80W-90. The differential fluid exchanges are pretty fun beginner self-learning maintenance items if you have access to a lift or a good jack/jack stands, make sure you've got the right size bits for the drain plug and fill plug. Fill plug is the one closer to the top of the vehicle, drain plugs on the bottom. Drain it out first obviously, clean off the magnet at the end of the drain plug and then put it back into the diff. Then loosen the top fill plug, clean the magnet and fill the reservoir until it can't be filled anymore. Get some new washers for the drain plugs and find the torque spec for a more professional + spiffy job=done
