The 2004 Acura TSX is a compact sport sedan that blends European-style handling with Honda-based dependability and a premium badge. This model year launched the first-generation TSX (2004–2008) in the U.S., replacing the Acura Integra sedan role with a more upscale, refined package. It’s ideal for drivers who want a responsive daily commuter with a high-quality interior and strong value on the used market. The TSX sits between mainstream family sedans and entry-level luxury competitors, offering a sporty feel without the high running costs of some rivals.

1) 2.4L i-VTEC 4-cylinder (K24A2): The 2004 TSX uses a high-revving 2.4-liter inline-4 known for smooth power delivery and strong midrange, paired to a 6-speed manual or 5-speed automatic (availability depends on trim/market). 2) Sport-sedan chassis tuning: Quick steering response, firm suspension calibration, and balanced handling make the TSX a standout for drivers who prioritize control and feedback. 3) Premium interior and ergonomics: Supportive seats, a driver-focused layout, and upscale materials give it a true near-luxury feel for its era. 4) Standard luxury conveniences: Most 2004 TSXs came well-equipped with features like a power moonroof, dual-zone climate control, and a strong factory audio system (exact equipment varies by package). 5) Practical sedan utility: A usable trunk, comfortable rear seat for a compact sedan, and good outward visibility make it easy to live with day to day.

Owners searching “2004 Acura TSX reliability” often find the car has a strong long-term track record when maintained, but several “2004 Acura TSX problems” show up repeatedly: 1) Power steering hose leaks and pump noise: A common issue is seepage from the power steering high-pressure hose or related seals, sometimes leading to a whining pump or heavier steering feel. This can appear around 100,000–150,000 miles, especially in colder climates or cars that have gone long intervals without fluid checks. 2) Oil consumption and leaks as mileage climbs: Some 2004 TSXs report oil usage between changes or minor leaks from aging gaskets (valve cover area is a frequent suspect). It’s not universal, but it becomes more common past 120,000 miles if oil changes were stretched. 3) Automatic transmission shift quality (5-speed automatic): While many automatics last a long time, some owners report rough or delayed shifting, especially if the fluid wasn’t changed regularly. Symptoms often show up around 120,000+ miles; frequent fluid service can make a big difference. Manual transmissions are generally robust, though clutches are wear items. 4) Suspension wear and front-end noises: Over time, struts, control arm bushings, and sway bar links can wear and cause clunks over bumps or uneven tire wear. This is a normal aging issue for a sporty suspension and commonly appears after 100,000 miles depending on road conditions.
