Best Model Years
2002-2005 (NA2 models with fixed headlights and 3.2L engine)
Years to Avoid

Top Risk Areas
The systems that tend to fail first on the 2004 Acura NSX, 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.
Control arm bushings, suspension components, engine seals (valve covers, oil pan), and various hoses simply degrade and harden over two decades, leading to leaks, rattles, and compromised handling.
While core electricals are robust, auxiliary items like the Bose amplifier, climate control unit display, power window motors, and alarm systems can become intermittent or fail due to age.
Brake calipers (especially rear) are prone to seizing due to lack of fluid changes or disuse. Master cylinders can also fail, leading to spongy pedal feel. ABS modulators are rare but expensive failures.
2004 Acura NSX Mileage Danger Zones
The mileage windows when the 2004 Acura NSX most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, the NSX is still relatively fresh. Focus is primarily on routine fluid changes and inspecting for any issues from prolonged storage rather than wear-related problems.
Maintenance Zone
This mileage brings the NSX into a critical preventative maintenance window, particularly for fluid systems and potentially addressing early signs of rubber component wear.
Elevated Risk Zone
This is a significant milestone for the NSX, typically requiring its second major timing belt service and likely needing attention to age-related wear items like seals, hoses, and suspension components.
High Risk Zone
While many NSXs reach this mileage, expect a more comprehensive refresh. Cars here without meticulous records will demand significant investment to bring them up to snuff, touching nearly all systems.

Annual Maintenance

Moderate Repairs
$1,500-3,500 occasionally (e.g., clutch, suspension refresh, timing belt)
How Long Does the 2004 Acura NSX Last?
For the NSX, pristine condition and impeccable service history trump absolute low mileage. A well-maintained 80,000-mile example is often a better buy than a lower-mileage car with deferred maintenance or extensive sitting time.
