Top Risk Areas
The systems that tend to fail first on the 2005 Infiniti G35, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The fuel level sensor often fails, causing inaccurate fuel gauge readings (empty when full, or erratic behavior). This is a very common issue across Nissan/Infiniti models of this era.
Window regulators, particularly on the driver's side, are prone to failure, leading to slow operation or the window dropping into the door. This often requires replacement of the entire regulator and motor assembly.
Over time, front lower control arm bushings and various other suspension components (like strut mounts, end links) wear out, leading to clunks, squeaks, and degraded handling. This is typical wear for a performance vehicle.
2005 Infiniti G35 Mileage Danger Zones
The mileage windows when the 2005 Infiniti G35 most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
This mileage range should be relatively trouble-free, primarily requiring routine fluid changes, tire rotations, and general inspections. Focus on verifying prior maintenance adherence.
Maintenance Zone
This is a critical interval for spark plugs, differential fluid, and potentially transmission fluid service. Pay close attention to the fuel gauge and windows, as these issues may begin to manifest.
Elevated Risk Zone
Expect age-related wear to accelerate. Suspension components will likely need attention, and engine gasket leaks become more probable. Electrical issues, if not present earlier, will likely surface.
High Risk Zone
At this mileage, a comprehensive review of all major systems is essential. Be prepared for a full suspension overhaul, potential catalytic converter issues, and a higher likelihood of power steering pump or major sensor failures.

Annual Maintenance
$400-600
Moderate Repairs
$500-1,500 occasionally
How Long Does the 2005 Infiniti G35 Last?
While examples with over 150,000 miles can be found running strong, target a G35 with under 120,000 miles and a verifiable service history. Be prepared to address common age-related wear items regardless of mileage.
