Well, i have been enjoying my G but i am having some issues that are forcing to possible trade it in. One issue is, my oil level is constantly falling. I changed my oil less than a month ago and i am already a quart short. I also noticed the oil is very dirty and watery. That concerns me because my coolant level has also been falling and i was told that it could be leaking into the engine. My third issue is when i am going beyond 40 mph, and i brake, the front of my car shakes violently. Has anyone had these issues or known of these issues and what could be the problem. Thanks

 

That's odd if you have an oil consumption in a 2003-2004 G35. As for the shaking when braking....warped rotors.

 

I changed my rotors in April. I have checked the rotors, and they are fine.

 

WOW-sounds like oil consumption issues. However, this just recently started. As far the radiator you may want to get a pressure test to see if you have any leaks. If you can not find leaks, You may be leaking anti freeze into the oil. If that is the case it is possible it started you oil consumption issues as well. This could cause the problem regarding oil consumption.

 

Both the oil and colant issue started in February or March. The oil issue seems to be a pretty common issue.

 

i just saw another thread here today that sounds very similar to yours. have a look:

you have oil consumption problems, take the car to an infinity dealership and theyll start an oil test. Basically you bring the car back every 1000 miles and they check the oil. Apparently if your car burns more than 1.5 quarts in 3300 miles they replace your engine. They give you a 2007 g35s to drive for a coupla weeks too

 

That thread had oil problems with the 5AT and it's transmission cooler ruptured, i think his is a 6MT according to his sig.

I don't even think that 2003-2004 non-rev engines had oil consumption issues.

 

The last two oil changes that i have done, i definitely do not flush out 5 quarts that i put in. I just checked it and it has not even been a 1000 miles and the dip stick is already showing that i need a quart of oil and the oil is black. Is that normal for less than a thousand miles for the oil to be black already when in the past, before i was having this issue, that was not the case but i could be wrong. Will infiniti throw a fit if i take it in since the car is still covered through the 6/70k powertrain if i did the oil changes myself? Will they also throw a fit if i have a Pop Charger and void my powertrain warranty? What do you guys think.

Also, any idea in regards to the vibration i am getting when i am breaking when i am beyond 40 mph keeping in mind that i changed my rotors and pads in April?

thanks for all the suggestions.

 

RedSkylineGT has an 03 5AT coupe (non revup) that had oil consumption issues
