1st generation (V35) · V35 (Nissan FM platform) · 1,573 complaints, 1,255 with mileage
Owners filed 1,573 complaints with NHTSA about the 2003–2006 Infiniti G35, and 1,255 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 49,000 and 113,000 miles. The median is 81,000 miles.
The most-reported areas are the electrical system (19.2% of complaints, typically around 93,000 miles), the engine (10.0% of complaints, typically around 108,000 miles), the exterior lighting (9.4% of complaints, typically around 81,000 miles).

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 81,000 miles; the figures below show which parts of the car run ahead of that and which run behind.
The electrical system accounts for 19.2% of complaints (302 reports, 254 of them with a mileage figure), with a median of 93,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 73,609 and 115,000 miles.
The engine accounts for 10.0% of complaints (157 reports, 129 of them with a mileage figure), with a median of 108,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 75,500 and 140,000 miles.
The exterior lighting accounts for 9.4% of complaints (148 reports, 109 of them with a mileage figure), with a median of 81,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 60,213 and 110,000 miles.
The engine and its cooling system accounts for 8.3% of complaints (131 reports, 119 of them with a mileage figure), with a median of 79,742 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 30,000 and 107,181 miles.
The airbag system accounts for 6.7% of complaints (106 reports, 77 of them with a mileage figure), with a median of 85,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 53,000 and 114,000 miles.
The hydraulic brake circuit accounts for 5.7% of complaints (89 reports, 66 of them with a mileage figure), and it fails early — a median of 14,284 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 9,000 and 28,000 miles.
Within this generation, complaint volume is not constant across model years. The 2003 model year drew the most — 737 complaints — while 2006 drew the fewest at 184. The median year sits at 326.
That makes 2003 an outlier: roughly 2.3 times the median year of this generation. A single year standing that far apart usually reflects either a first-year issue that was later corrected, or a component change introduced for that year. Anyone shopping this generation has a straightforward reason to prefer a different year, all else being equal.
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.
Of the 1,573 complaints filed against this generation, 73 reported a crash; 28 reported a fire; 43 reported an injury; 5 reported a fatality. Crash-involved reports represent 4.6% 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.
For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 49,000 and 113,000 miles, with a median of 81,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, the electrical system and the engine 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 93,000, 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.
High oil consumption and blow-by from worn piston ring sealing, typically surfacing around 60,000-80,000 miles on the earliest cars.
Premature wear of the timing chain rail guides and tensioner causes rattle/tapping; disintegrating guide material can fall into the oil pan and block pickup.
Position sensor failures cause stalling at idle and no-start conditions; failure rates were high enough that Nissan addressed them through a recall/service campaign.
Rotor warping and rapid pad wear generate heavy vibration complaints, concentrated on the sedan in the early years.
TCC solenoid failure as early as around 30,000 miles causes slippage and hard shifts; the fix pairs solenoid replacement with a PCM reflash per TSB.
