A Comprehensive Guide to the Acura RSX

The Acura RSX, known as the Honda Integra in most other markets, is a front-engine, front-wheel-drive sports coupe manufactured by Honda and marketed under Acura from 2001 to 2006. It served as the successor to the Acura Integra in North America, aiming to capture the hearts of driving enthusiasts with its sporty handling, sleek design, and potent engine options. The RSX falls into the compact sports coupe category, offering a blend of performance and practicality, attracting a diverse range of buyers from students to seasoned car enthusiasts.

Generations

  • First Generation (2002-2006)
    • Key Changes: This was the only generation of the RSX sold in North America. It featured two main trims: the base RSX and the Type-S. The base model featured a 2.0-liter K20A3 i-VTEC engine, while the Type-S boasted a more powerful 2.0-liter K20A2 (later K20Z1) i-VTEC engine, a close-ratio 6-speed manual transmission, and sport-tuned suspension. The exterior design remained largely consistent throughout its production run, with minor tweaks to the headlights and taillights in the 2005-2006 model years.

Reliability & Common Issues

Engine

The K-series engines in the RSX are generally considered very reliable, but like any engine, they have their quirks:

  • VTEC Solenoid Issues: Oil leaks from the VTEC solenoid gasket are common and relatively inexpensive to fix. Listen for a rattling sound upon VTEC engagement, which could indicate wear.
  • Oil Consumption: Some RSX models, particularly older ones, may experience oil consumption. Regular monitoring of oil levels is crucial. Using the correct viscosity oil is also important.
  • Timing Chain Tensioner: While generally robust, the timing chain tensioner can wear over time, especially in higher mileage vehicles. Listen for a rattling sound, particularly on startup. A failing tensioner can lead to catastrophic engine damage.
  • Knock Sensor: The knock sensor can fail, leading to reduced engine performance and potentially triggering a check engine light.

Transmission

  • Manual Transmission (Type-S): The 6-speed manual transmission in the Type-S is typically strong, but can suffer from wear. Synchro wear, particularly in 2nd and 3rd gears, is common in vehicles that have been driven aggressively. Grinding during shifts is a key indicator. A worn clutch is also expected on higher mileage cars.
  • Automatic Transmission (Base Model): The automatic transmission in the base RSX is generally reliable, but regular fluid changes are essential. Neglecting maintenance can lead to premature failure. Jerky shifting can indicate problems.

Suspension & Steering

  • Suspension Components: Bushings, ball joints, and tie rod ends are wear items that will eventually need replacement. Listen for clunking noises over bumps.
  • Power Steering: Power steering leaks are possible, particularly at the pump and rack.
  • Rear Trailing Arm Bushings: These bushings are prone to wear and can cause instability at higher speeds.

Electrical

  • Multiplex Control Unit (MCU): The MCU controls various electrical functions, and failures can cause intermittent issues with lights, wipers, and other accessories. Diagnosis can be tricky.
  • Door Lock Actuators: Door lock actuators are prone to failure.
  • Sunroof Issues: The sunroof motor can sometimes fail.

Body & Interior

  • Rust: Check for rust, particularly in areas like the rear wheel wells, rocker panels, and undercarriage.
  • Interior Wear: Check for wear on the seats, steering wheel, and shift knob. The driver's seat bolster is a common wear point.

Driving Experience

Pros:

  • Engaging Handling: The RSX offers sharp and responsive handling, making it fun to drive on winding roads. The Type-S, with its sport-tuned suspension, is particularly enjoyable.
  • Potent Engine: The K20 engines are known for their rev-happy nature and VTEC performance. The Type-S delivers a noticeable power boost compared to the base model.
  • Sleek Design: The RSX boasts a sporty and timeless design that still looks good today.
  • Practicality: Despite being a coupe, the RSX offers decent cargo space and can comfortably accommodate passengers in the front seats.
  • Aftermarket Support: A large aftermarket exists for the RSX, making it easy to find performance upgrades and replacement parts.

Cons:

  • Road Noise: The RSX can be noisy on the highway, particularly on rough roads.
  • Ride Quality: The ride can be firm, especially in the Type-S.
  • Interior Quality: While functional, the interior materials are not the most luxurious.
  • Potential for Abuse: Many RSXs have been modified or driven hard, so finding a well-maintained example can be challenging.

Buying Advice

What Years to Look For:

  • 2005-2006 Models: These models received minor cosmetic updates and improvements over the earlier years. The Type-S also received the K20Z1 engine, which is considered slightly more refined than the K20A2.

What to Avoid:

  • Severely Modified Vehicles: Unless you are comfortable with modifications and know what to look for, it's generally best to avoid vehicles that have been heavily modified.
  • Neglected Examples: Look for signs of poor maintenance, such as dirty engine bay, worn tires, and deferred repairs.
  • Cars with Evidence of Accidents: Carefully inspect the vehicle for signs of bodywork or frame damage. A pre-purchase inspection by a trusted mechanic is highly recommended.
  • Vehicles with Significant Rust: Rust can be expensive to repair and can compromise the structural integrity of the vehicle.

Key Considerations:

  • Pre-Purchase Inspection: A thorough inspection by a qualified mechanic is essential to identify any potential problems.
  • Maintenance Records: Ask for maintenance records to verify that the vehicle has been properly maintained.
  • Test Drive: A comprehensive test drive is crucial to assess the vehicle's performance and identify any issues with the engine, transmission, suspension, and brakes. Pay attention to any unusual noises or vibrations.
  • Title Check: Run a vehicle history report (e.g., Carfax or AutoCheck) to check for accidents, title issues, and odometer fraud.
  • Type-S vs. Base Model: Decide whether the extra performance and features of the Type-S are worth the premium. The base model can be a good option for those looking for a more comfortable and fuel-efficient daily driver.
  • Mileage: While the K-series engines are durable, higher mileage vehicles may require more maintenance and repairs.

By following these guidelines and conducting thorough research, you can find a well-maintained Acura RSX that will provide years of driving enjoyment.
