Well, leaky steering racks, bad wheel bearings, peeling/scratching of trim pieces, and brake judder were very popular on the 2007-2008 G35, which is the same v36 design. However, the trim pieces have been redesigned since 2009 so there shouldn't be any problem with those. Infiniti decided to not use the rubberized paint like they used to.

As for leaky steering racks and bad wheel bearings, I'm not sure if they were changed for the newer model years. They usually do go bad after about 50-60k miles, from what I've seen in the g35driver forums. Leaky steering racks aren't as common, but they do happen on several occasions. Wheel bearings, however, are a common problem on our cars. Creaking noises are also very popular too, but the creaks I've experienced seem normal on my car, probably needed to lube the bushings. As for the brakes, I just changed out the pads and rotors to an aftermarket brand and they're much better. The OEM ones aren't as good, and the brake pad/rotor combination causes the judder issue pretty quickly.

My car is now 75k miles, and so far no problems so far since all that warranty work has been done. I'm still sure that if I had gotten a German car, my problems would be worse. My friend's Audi had to be in the shop more often than mine. My problems were actually more silly and cosmetic than his problems. I was pretty **** about my car so I was able to detect problems in my car far sooner than other people. My girlfriend couldn't notice any problems or sounds but I do. My wheel bearings were only mildly worn when they were replaced; I was able to detect some weird sounds coming from my tires when nobody else could hear them.

 

Not to bump, but an update. I am now the proud owner of a 2010 black on black G37x with the Nav package. 28k miles on it. I was very, very sad to let the RX-8 go, but so far I am liking the new ride. Now to look into (simple mods). Tinted windows and wheels first most likely. The stock Bose system is pretty good as-is.

 

Congrats on the new G! Post some pictures when you get a chance!! Any idea what type of wheels you're looking to put on it?

 

Not sure yet. I've got to first sell my winter tires and rims that I had for my RX-8. And the weather is **** here right now, salt all over the car.

 

What color did you get? Looking for 2010 G37x w/Nav and premium. I could get it in white or sahara sandstone mid 20s. I want black or blue slate. Most are 3K more. (Philadelphia area)
