Acura RLX: A Comprehensive Guide

The Acura RLX was Acura's flagship sedan, positioned in the full-size luxury sedan segment. It aimed to blend Acura's reputation for reliability and value with the comfort, technology, and performance expected in the premium market. Produced from 2014 to 2020, the RLX sought to compete with established rivals like the Lexus GS, BMW 5 Series, and Mercedes-Benz E-Class. While it offered innovative technology and a comfortable ride, it faced challenges in gaining market share against its more established competitors.

Generations

  • First Generation (2014-2020): This was the only generation of the Acura RLX. It underwent a mid-cycle refresh in 2018.
    • 2014-2017: Introduced with a 3.5-liter V6 engine and either front-wheel drive (FWD) with Precision All-Wheel Steer (P-AWS) or all-wheel drive (AWD) with the Sport Hybrid Super Handling All-Wheel Drive (SH-AWD) system. Key features included advanced safety technologies, comfortable seating, and a spacious interior.
    • 2018-2020 (Facelift): The RLX received a significant refresh, including updated exterior styling, improved interior materials, and enhancements to the SH-AWD system. Acura also standardized the Sport Hybrid SH-AWD system, making it the sole powertrain option. The facelift aimed to improve the RLX's competitiveness and appeal in the luxury sedan market.

Reliability & Common Issues

The Acura RLX, like many Honda/Acura products, generally enjoys a good reputation for reliability. However, like any vehicle, it has its share of potential issues. Understanding these can help you make an informed buying decision.

Engine (3.5L V6):

  • VCM (Variable Cylinder Management): The 3.5L V6 uses VCM to improve fuel economy by deactivating cylinders under light load. This system has been known to cause oil consumption issues in some cases. Symptoms include excessive oil usage and potential fouling of spark plugs. Regular oil level checks and timely oil changes are crucial. Consider disabling VCM with aftermarket devices if you are concerned about long-term engine health.
  • Direct Injection Carbon Buildup: As a direct-injected engine, carbon buildup on the intake valves can occur over time. This can lead to decreased performance, rough idling, and misfires. Regular cleaning of the intake valves (e.g., walnut blasting) may be necessary.
  • Timing Belt (Pre-2018 Non-Hybrid): RLX models *without* the hybrid system used a timing belt that requires replacement approximately every 100,000 miles or 7 years. Failure to replace the timing belt can result in catastrophic engine damage. This is a critical maintenance item to consider. The hybrid models use a timing chain, which is much longer-lasting and typically does not require replacement.

Transmission:

  • 9-Speed Automatic (2018-2020 Hybrid): Some owners have reported occasional rough shifting or hesitation with the 9-speed automatic transmission found in the hybrid models. Software updates can sometimes address these issues, but more serious problems may require transmission repairs or replacement.
  • 6-Speed Automatic (2014-2017 Non-Hybrid): Generally considered more reliable than the 9-speed, but regular fluid changes are essential for maintaining optimal performance and longevity.

Hybrid System (SH-AWD models):

  • Battery Pack: The hybrid battery pack has a finite lifespan and will eventually need replacement. While Acura hybrid batteries are generally durable, the cost of replacement can be significant. Consider the age and mileage of the vehicle when assessing the battery's health. Diagnostic scans can provide insights into the battery's condition.
  • Electric Motor Issues: Although relatively rare, problems with the electric motors in the SH-AWD system can occur. These issues may manifest as a loss of power, unusual noises, or error codes.

Other Potential Issues:

  • Precision All-Wheel Steer (P-AWS): The P-AWS system on FWD models can sometimes experience issues with the rear steering actuators. Symptoms may include unusual handling characteristics or error messages.
  • Navigation/Infotainment System: The infotainment system, particularly in older models, can feel dated and may experience glitches or software issues.
  • Suspension Components: Check for worn suspension components, such as shocks, struts, and bushings, especially on higher-mileage vehicles.

Driving Experience

The Acura RLX offers a comfortable and refined driving experience, prioritizing smoothness and quietness over outright sportiness.

Pros:

  • Comfortable Ride: The RLX excels in providing a comfortable ride, absorbing bumps and imperfections in the road with ease.
  • Quiet Cabin: The interior is well-insulated, minimizing road and wind noise for a peaceful driving experience.
  • Advanced Technology (SH-AWD): The SH-AWD system provides excellent traction and handling, particularly in inclement weather. It enhances stability and control.
  • Fuel Efficiency (Hybrid): The Sport Hybrid SH-AWD models offer impressive fuel economy for a full-size sedan.
  • Spacious Interior: The RLX offers ample legroom and headroom in both the front and rear seats.
  • Value for Money: Compared to its European rivals, the RLX offers a compelling value proposition, with a lower price point and competitive features.

Cons:

  • Lack of Excitement: The RLX prioritizes comfort over sportiness, which may not appeal to drivers seeking a more engaging driving experience.
  • Styling: The RLX's styling was generally considered conservative and understated, which may not stand out in a crowded market.
  • Infotainment System: The dual-screen infotainment system can be cumbersome to use, especially compared to more modern systems.
  • Resale Value: The RLX's resale value is generally lower than that of its German competitors.

Buying Advice

If you're considering purchasing an Acura RLX, here's some advice to help you make the right choice:

Years to Look For:

  • 2018-2020 (Facelift Models): The facelifted RLX models offer improved styling, upgraded interior materials, and the standardized Sport Hybrid SH-AWD system. These are generally the most desirable years to consider.

Years to Avoid (or be cautious of):

  • 2014-2017 (Early Models): While generally reliable, these models have the older styling, potentially outdated technology, and the timing belt that needs replacing. Also, the non-hybrid versions are front wheel drive and may exhibit torque steer.

Key Considerations:

  • Maintenance History: Thoroughly review the vehicle's maintenance history to ensure that it has been properly maintained. Pay close attention to oil changes, timing belt replacement (if applicable), and transmission fluid changes.
  • Pre-Purchase Inspection: Have a qualified mechanic perform a pre-purchase inspection to identify any potential issues before you buy. This is especially important for hybrid models, where the battery health should be assessed.
  • Test Drive: Take the vehicle for a thorough test drive, paying attention to the engine performance, transmission smoothness, handling, and brake feel. Ensure that all features and systems are working properly.
  • Hybrid Battery Health: If you're considering a Sport Hybrid SH-AWD model, inquire about the age and condition of the hybrid battery pack. Diagnostic scans can provide insights into its health.
  • VCM Issues: Be aware of the potential for VCM-related oil consumption issues in the 3.5L V6 engine. Check the oil level regularly and monitor for any signs of excessive oil usage.
  • Pricing: Research the market value of similar RLX models in your area to ensure that you're getting a fair price. The RLX often depreciates quickly, so you may be able to find a good deal.

By carefully considering these factors, you can find an Acura RLX that meets your needs and provides a comfortable and reliable driving experience.
