I've noticed that my clutch slips slightly if I engage the clutch at too high an RPM. This might be a design of the transmission. I don't know. But there are several aftermarket clutch kits that will probably fix the problem.
I guess needing clutches at 40,000 miles just goes with owning a Japanese car. My last stick-shift car (Dodge) had 240,000 miles on it with never a bolt turned on it except for 2 brake jobs and 2 timing belts. My 5-speed Mustang had 105,000 on it when I sold it. Never a problem with the clutch (or anything else) on it either. Kinda makes me wonder what you REALLY get for your $40,000. I'll take TWO Mustangs any day.
I really hate the VDC system on my 2004 G35 coupe, I can't even keep up with my brothers Integra type-R with it on.
I bought a 2006 G35MT in December 2005 and drive about 15,000/year. I noticed the clutch slipping when under hard acceleration from a dead stop, like getting on a freeway on-ramp. The dealer adjusted the clutch, but had to replace it at 12,000 miles telling me "not to accelerate until the clutch is fulling engaged". I have 30,000 miles on it now and have been driving it to eliminate slippage and today under hard acceleration it started slipping again; time for another clutch. I'll go aftermarket for a heavy duty one to see if that is better.
I just bought a used 04' G35 6MT. Have had it now for 2 months.
First thing I noticed is the clutch, as others have mentioned. Took a good 2 weeks to get used to.
Things I have noticed about the clutch;
1) The car prefers agressive high rev gear shifting. This hits gas mileage, but the exhaust makes it sound worse than it is. My wifes SUV auto, shifts around 3K RPM's.. in the G35.. shifting at 3K RPM's sounds like you are trying to race someone. But the car likes to shift around 3.5K or higher. so.. it sounds like you are racing at every stop light, it's kinda fun though once you get used it.
2) the car does not like accelerating and shifting at the same time.. it definitely prefers to fully shift into gear foot off the gas pedal and then engage... This specifically is what I think tends to wear out the clutch fast in this and many Japanese cars. This is also kind of fun once you get used to it.. cause you sort of launch forward when you hit the gas again after shifting.
Other things... the GPS is a little annoying that the screen is very hard to see in the day time. The engine rumble at idle is not quite as smooth as I would expect from a luxury version sports coupe. But again, it's kinda fun once you get used to it and realize it's a big rumbling engine.
Sound system could be better.. especially for a bose. But it does the job.
The seat belt is a little annoying as it is difficult to keep it from banging/scratching/knicking the door material every time you put it on and off.. you have to consiously be careful with it.
The back seat and trunk are both surprisingly roomy for a sports car.
I think mechanically the clutch is obviously the most glaring issue, but I think you just need to learn how it likes to be driven.
Overall, the car is a lot of fun to drive and beautifully designed.
I love driving manual.. and for cars like a G35, you should be driving manual.. but if you are dead set on a G35.. I would probably suggest going with the automatic unless you are an expierinced driver with Japanese manual transmissions.
THE G35 is a very nice car, however I thought by owning a rear wheel drive this time, I'd be driving a much more reliable car with less noises!!! My brother and I, bought 2 G35 coupes and we're facing same problems... SAME squeak sounds!
Really similar to that of a PICK UP.. and I want to make sure if the sound can be heard from outside as well.
I think the hardest thing is to repair such things, and you don't know if you need to change the whole front suspension, and which part!
2004 G35 Coupe 6MT.
I bought this car for a little more than a year now, and I realize this car does not like the heat. When the weather is hot, everything seems to go wrong with a suppose $40,000 luxury coupe. The clutch starts to stick easily, which will cost you a lot to replace. The CD changer will not play, which is embarrassing for a car that cost this much. And also, the power door lock will not function right. When I bring the car to the nearby dealership, they told me is wear and tear problem, but I personally think is the way the car is design.
For a car that cost $40,000, and bear a "luxury" coupe title, it should have better quality than this.
I have previously owned a Honda Civic for 5 yrs, a Subaru WRX for 2 yrs, and a Subaru WRX STI 4 yrs and they never have any similar problems.
Especially the clutch, there is no way a clutch only last 20,000 miles when is driving under normal condition daily. Infiniti/Nissan really messed up on this one.
I agree with all the cons.
At first I thought my clutch had a problem because it was so heavy, especially compared to the 2005 G35 coupe (I own the 04 coupe), but I guess it is naturally heavy. It does skip sometimes, but then it is fine so I don't really know if it needs replacement or not.
At 75k I have changed the battery twice. Haven't changed anything else as far as the engine (except I installed a cool air intake when I first bought it).
The seat belt is another problem. I wonder how much it would cost to replace it.
Also my driver's leather seat has a rip on it. The compartment above the glove compartment is falling apart. For a luxury car, I guess I expected more from the interior quality.
That said, I fall more in love with this car the more I drive it. I think someone mentioned that Japanese cars don't have torque, this is an exception. I have not yet found a more fun to drive car in this price range (comparing the current G with other current models). And above all it is sexy, even after 5 years! I would NEVER trade this for a Mustang!
2005 G35 6MT. I have owned this car for a year and love it; great looks, awesome performance, love it.
I just got a 2006 G35 Coupe 1 week ago! Let me tell you one thing, this is the best driving sports car I have ever been in. It feels very solid and tight. I think I couldn't have made a better choice. I think this car is worth every penny ($21,000). Great take off speed and super good looks! I have to go outside several times a day just so I can look at its sexy lines again and again! Infiniti got this one right!!
