Infiniti G35 2007–2008

2nd generation (V36, G35 badge years only) · V36 (Nissan FM platform, 2nd gen) · 284 complaints, 208 with mileage

Owners filed 284 complaints with NHTSA about the 2007–2008 Infiniti G35, and 208 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.

Failures are spread across the mileage range, with the middle half between 28,000 and 103,000 miles. The median is 69,864 miles.

The most-reported areas are the airbag system (23.6% of complaints, typically around 78,100 miles), the electrical system (10.6% of complaints, typically around 77,500 miles), the transmission and driveline (8.8% of complaints, typically around 34,473 miles).

Which systems, and when

Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 69,864 miles; the figures below show which parts of the car run ahead of that and which run behind.

The airbag system accounts for 23.6% of complaints (67 reports, 53 of them with a mileage figure), with a median of 78,100 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 50,000 and 108,000 miles.

The electrical system accounts for 10.6% of complaints (30 reports, 20 of them with a mileage figure), with a median of 77,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 49,000 and 120,000 miles.

The transmission and driveline accounts for 8.8% of complaints (25 reports, 21 of them with a mileage figure), and it fails early — a median of 34,473 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 8,000 and 85,000 miles.

Problems owners could not categorise accounts for 7.0% of complaints (20 reports, 12 of them with a mileage figure), with a median of 86,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 67,400 and 100,000 miles.

The engine accounts for 7.0% of complaints (20 reports, 14 of them with a mileage figure), and it fails late — a median of 106,500 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 85,000 and 125,000 miles.

The engine and its cooling system accounts for 4.6% of complaints (13 reports, 11 of them with a mileage figure), and it fails early — a median of 10,130 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 200 and 69,729 miles.

Recalls and what they cover

NHTSA records 1 recall campaign covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.

Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.

Reported severity

Of the 284 complaints filed against this generation, 27 reported a crash; 2 reported a fire; 11 reported an injury. Crash-involved reports represent 9.5% of the total.

These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.

What this means if you are buying one

For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 28,000 and 103,000 miles, with a median of 69,864. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.

On inspection, the airbag system and the electrical system are where this generation's reports concentrate, so those are the areas worth a specific look. The electrical system in particular shows a median failure mileage of 77,500, which gives a concrete number to compare against the odometer of any car you are considering.

None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.
