The Lexus RX, a pioneer in the luxury crossover segment since its introduction in 1998, continues its legacy with the 2021 model. It's a mid-size SUV known for its comfortable ride and upscale features. Key trims include the base RX 350, RX 350 F Sport, RX 450h (hybrid), and RX 450h F Sport. The 2021 RX had an original MSRP ranging from approximately $45,000 to $58,000 depending on the trim and options. Its reputation for reliability and smooth driving experience make it a popular choice.
The Good

The 2021 Lexus RX offers a smooth and comfortable ride, appealing to those seeking a relaxed driving experience. Known for exceptional reliability, it reduces long-term ownership concerns, a practical benefit. The elegant design and luxurious interior provide an emotional connection. The hybrid version enhances fuel efficiency, offering both environmental and economic advantages. While not a performance SUV, its refined nature is a definite advantage.

The Bad

Analysis

What Problems Does the 2021 Lexus RX Have?

While the Lexus RX generally enjoys a strong reputation for reliability, some issues have been reported for the 2021 model year. One of the most common complaints revolves around the infotainment system's touchpad interface, which many users find distracting and unintuitive to operate while driving. Some owners have also reported issues with the automatic emergency braking system, including phantom braking incidents.

Specifically regarding recalls, it's essential to check the NHTSA (National Highway Traffic Safety Administration) website for any active recalls affecting the 2021 Lexus RX, as recalls can be issued for various reasons throughout a vehicle's lifespan. Past RX models have occasionally faced recalls related to fuel pumps, airbags, and other safety-related components, so checking for any applicable recalls to the 2021 model is crucial.

Long-term reliability concerns are relatively minimal for the RX, but as with any vehicle, proper maintenance is key. Hybrid models (RX 450h) require specific attention to the hybrid battery and related components. Some owners have reported minor electrical issues or sensor malfunctions over time. Regular servicing, including oil changes, brake inspections, and fluid checks, will help to mitigate potential problems and ensure the RX's long-term durability.

How long will the 2021 Lexus RX last?

With proper maintenance, a 2021 Lexus RX can easily exceed 200,000 miles and provide over 10 years of reliable service. Lexus vehicles are known for their durability, and the RX is no exception. Key to longevity is adhering to the recommended maintenance schedule, including timely oil changes, fluid flushes, and inspections.

The hybrid RX 450h models may require battery maintenance or replacement eventually, which is a significant but predictable cost. Potential weaknesses might include wear and tear on suspension components and the infotainment system. However, overall, the RX is a durable vehicle built to last.

What Technology & Safety Features are Included?

The 2021 Lexus RX boasts a solid suite of technology, entertainment, and safety features. Standard tech includes an 8-inch infotainment display (upgradeable to 12.3-inch), Apple CarPlay, Android Auto, Amazon Alexa compatibility, and multiple USB ports. The infotainment system is controlled by a touchpad, which some find cumbersome.

Standard driver-assistance features are bundled in the Lexus Safety System+ 2.0, including pre-collision system with pedestrian detection, lane departure alert with steering assist, lane tracing assist, adaptive cruise control, and road sign assist. Optional features include blind-spot monitoring with rear cross-traffic alert, parking assist, and a panoramic view monitor.

For entertainment, a premium Mark Levinson sound system is available as an option, providing excellent audio quality. A head-up display is also offered, projecting key information onto the windshield.

In terms of safety, the 2021 Lexus RX performed well in crash tests conducted by the IIHS (Insurance Institute for Highway Safety) and NHTSA (National Highway Traffic Safety Administration). Check the official IIHS and NHTSA websites for specific crash-test ratings and reports to get the most up-to-date information.

2021 Lexus RX Insurance

Insurance for a 2021 Lexus RX is moderately priced, reflecting its status as a Sport Utility Vehicle with strong safety ratings and
reasonable repair costs.

How Does the 2021 Lexus RX Compare to Other Sport Utility Vehicle?

The 2021 Lexus RX competes with other mid-size luxury SUVs like the Acura MDX, BMW X3/X5, Mercedes-Benz GLE, and Audi Q5. In terms of performance, the RX prioritizes comfort over sportiness, lagging behind the BMW X3/X5 and Mercedes-Benz GLE in terms of handling and acceleration. However, it offers a smoother ride. Feature-wise, the RX is well-equipped, but its infotainment system is less user-friendly than those found in the BMW and Mercedes-Benz.

Reliability is a major strength of the RX, often outperforming its European rivals in long-term dependability. The Acura MDX is a strong competitor in this area as well. Price-wise, the RX is generally competitive, though it can get expensive with options.

Alternatives to consider include:
  • Acura MDX: Offers similar reliability and practicality with a more engaging driving experience.
  • BMW X3/X5: Provides superior performance and a more modern infotainment system but may have higher maintenance costs.
  • Mercedes-Benz GLE: Delivers a luxurious interior and advanced technology but can be less reliable.
If reliability and comfort are top priorities, the RX is an excellent choice. If you desire a sportier driving experience, the BMW or Acura might be better alternatives.
