If you love the Nissan 350z but want a more refined version, the Infiniti G35 is right up your alley. It’s sophisticated, comfortable, and doesn’t compromise on performance thanks to its improved weight distribution based on the FM platform.
Although the G35 was aimed at drivers looking for a luxury car, it has since seen a rise in popularity amongst those in the VIP and tuning scene. In fact, with its longer wheelbase, the G35 is popular with many drift car owners looking for a steady and controlled drift.
Because the Infiniti G35 has so much to offer, our guide will take a look at the reliability, specs, and common problems for both the coupe and sedan.
History of the Infiniti G35
Production of the G35 started in 2002 by Nissan –– the manufacturer who makes the Infiniti G35. While earlier cars in the Infiniti G-series were based on the Nissan Primera, the G35s and many of its successors are all re-badged versions of Nissan Skyline. The G35 was developed on the FM platform alongside the Nissan 350z.
There were a number of cosmetic changes and redesigns in the G35’s six-year-long run, with its 2005 refresh being the most prominent. The 2005 model not only got an upgraded engine but also an upgraded limited-slip differential, brakes, and dashboard.
However, by 2008 Infiniti entirely shifted its focus towards the production of the G37 which is why the G35 was discontinued. The difference between a G35 and G37 may be hard to spot at first glance, which goes to show how much of an impact the G35 had on later Infiniti designs.

From 2003 to 2006, the Infiniti G35 came equipped with the VQ35DE engine which got revised in 2007. It wasn’t so much of a revision though. The engine was completely revamped.
After 2007 The G35 came with the VQ35HR engine — a much more reliable version of the DE motor with dual throttle bodies, hydrogen-free DLC coated valves, and most importantly, continuously variable valve timing.

So how much horsepower does a G35 have? Although the 2003 model produced only 260 hp, the later models produced 280, 298, and 306 hp respectively.
The G35 has a rear-wheel-drive layout, a 52% front and 48% weight distribution, and a 5-speed automatic transmission. A 6-speed manual transmission was available on the sedan for the 2004 model, which received an upgrade to 18-inch wheels.
Infiniti also introduced an all-wheel-drive option known as the G35x with a 5-speed automatic transmission.
While the G35 is available only as a sedan and coupe, Infiniti kept things interesting by introducing several trim packages listed below.
The Base G35 model has a 5-speed automatic and auto-manual transmission. The G35 sedan’s engine pumps out 306 hp while the coupe manages only 275 hp.
Additionally, the Base G35 coupe is also available with an upgraded 6-speed manual transmission which easily churns out 298 hp.
Infiniti fitted a variable valve timing on the intake and exhaust camshafts in the manual cars. The automatic cars had variable valve timing only on the intake inside. Also, a sport-tuned suspension package became standard on all six-speed manual models.
The Journey trim is available only as a sedan and has a 5-speed automatic transmission, with an engine pumping out 306 hp.
The G35 Journey has everything that a Base G35 has, along with a few other features like:
- 4-way power passenger’s seat

Infiniti upgraded the tires on the sport package by upgrading them to 18-inches and making the brakes larger. The automatic Sport model even has bolstering seats that adjust on the inside and the bottom, providing pull-out thigh support.

Common Problems with the Infiniti G35
Although the G35 is a reliable vehicle, it’s not flawless. But then again, which car is?
Over the years, there have been several issues reported by G35 owners. We’ve listed the most common ones below.
Defective Brembo Brake Pads
This is probably the most common problem that you’ll have on a G35, particularly with the 2003 to 2005 sedans.
Many owners complained about the defective Brembo brake pads and rotors on these models and having to replace their rotors and discs every 15,000 to 20,000 miles. They also tend to emit excessive noise even before you wear them out.
The saving grace was when Infiniti finally fixed this problem in their later models. The calipers themselves are exceptional.
Quite a significant number of G35 drivers reported that they dealt with problems in their front suspension.
Other drivers reported having problems with the control arms and hearing clunking noises after installing G35 coilovers –– particularly when going over bumps and uneven roads.
While it’s difficult to pinpoint the root cause, replacing the old bushings with polyurethane ones seems to make things a lot more bearable.
Excessive Oil Usage
Unfortunately, the G35’s engine burns more oil than you’d probably like. But that’s the price you pay for having a powerful vehicle. In some cases this is caused by imperfect timing due to a bad crank position sensor.
Of course, the G35’s oil usage is also affected by your climate and driving style. To avoid these problems, it’s best that you have the car inspected before you buy it, then every year after that.
Is the G35 Worth Purchasing?
If you want to have more fun behind the wheel, the G35 is the right choice for you. It’s sleek, sporty, and has an irresistible mid-2000s charm. Sure, it’s not perfect, but its pros definitely outweigh the cons.
The Infiniti G35 price for a 2008 model back in the day was $32,000. Now, you can pick it up from anywhere between $2,000 and $7,000 which is a great bang for your buck.
