2004 Acura RSX — Known Trouble Spots
The systems that tend to fail first on the 2004 Acura RSX, 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 A/C compressor clutch and sometimes the entire compressor unit are prone to failure, often exhibiting a grinding noise or complete loss of cooling. This is a common Honda/Acura issue of this era.
Power steering pumps can develop leaks or become noisy, particularly on cold starts. Hoses and seals can also degrade, leading to fluid loss and potential pump damage if not addressed.
Front lower control arm bushings and strut mounts are wear items that can lead to clunking noises, reduced handling precision, and uneven tire wear. Rear trailing arm bushings can also fail, though less common.
2004 Acura RSX Mileage Danger Zones
The mileage windows when the 2004 Acura RSX most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, the RSX is barely broken in. Focus on ensuring routine fluid changes (oil, transmission) were performed and checking tire wear.
Maintenance Zone
This is a critical interval for major service. Ensure spark plugs, cabin/engine air filters, and potentially automatic transmission fluid have been replaced.
Elevated Risk Zone
Beyond 90k, components like the A/C compressor, power steering pump, and control arm bushings begin to show their age. A thorough inspection of these areas is crucial.
High Risk Zone
At this mileage, any RSX without a meticulous service history will start needing significant attention. Comprehensive review of all systems, including VTC actuator and potential rust spots, is paramount.

How Long Does the 2004 Acura RSX Last?
Focus on a meticulous service history rather than just low mileage; a well-maintained 100,000-mile RSX is often a better buy than a neglected 60,000-mile example. Be prepared for age-related wear on rubber components and accessories.
