Lexus RZ 450e: A Comprehensive Guide

The Lexus RZ 450e represents Lexus's dedicated foray into the all-electric vehicle (BEV) market. As a luxury compact SUV, it aims to blend Lexus's renowned refinement and quality with the environmental benefits and performance characteristics of electric propulsion. It signifies a critical step in Lexus's broader strategy towards electrification, positioning them to compete with other premium EV offerings in the segment.

Generations

First Generation (2023 - Present)

  • Years: 2023 – Present
  • Key Changes:
    • First all-electric Lexus model built on the e-TNGA platform (co-developed with Toyota).
    • Direct4 all-wheel-drive system for enhanced handling and traction.
    • Spindle Body design language, a variation on Lexus's signature spindle grille tailored for electric vehicles.
    • Steer-by-Wire system (optional, known as One Motion Grip) eliminating mechanical connection between the steering wheel and wheels.
    • Advanced driver-assistance systems (ADAS) including Lexus Safety System+ 3.0.
    • Focus on interior comfort and quietness, with sound dampening and optimized aerodynamics.
    • Powered by a 71.4 kWh lithium-ion battery pack.

Reliability & Common Issues

As a relatively new model, long-term reliability data for the RZ 450e is still emerging. However, we can make some informed observations based on the underlying technology and initial reports.

Battery and Powertrain

The e-TNGA platform and the associated electric powertrain components are based on technologies shared with Toyota's bZ4X. Therefore, early bZ4X issues provide insight. Potential concerns include:

  • Battery Degradation: As with all electric vehicles, battery degradation is a concern. Factors like charging habits, climate, and driving style can influence the rate of degradation. Lexus offers a battery warranty, but carefully monitor your vehicle's range over time.
  • Charging Infrastructure Dependence: While not a direct issue with the car, reliability is tied to the availability and functionality of public charging infrastructure.
  • Charging Speeds: While the RZ 450e supports DC fast charging, charging speeds may vary depending on the charger and environmental conditions. Keep up to date with real-world charging experiences reported by owners.
  • Software Glitches: Modern vehicles are heavily reliant on software. Issues can occur with the infotainment system, ADAS features, or battery management system. Look for software updates addressing any reported problems.
  • AWD System (Direct4): The Direct4 AWD system, while advanced, introduces additional complexity. Monitor for any unusual noises or performance issues related to the system.

General Lexus Reliability

Lexus, as a brand, has a long-standing reputation for high reliability. This reputation generally carries over to their electric vehicles. However, keep the following in mind:

  • Electrical Systems: With a heavily computerized vehicle, all electrical systems, from window controls to infotainment, are potential points of failure. Ensure these systems are functioning correctly during pre-purchase inspections.
  • Fit and Finish: Lexus maintains high standards for build quality. Inspect the interior and exterior for any imperfections, especially panel gaps or loose trim.
  • Suspension and Brakes: These components are subject to normal wear and tear. Check for excessive wear on brake pads and rotors, as well as any signs of suspension issues (e.g., clunking noises).

Driving Experience

Pros

  • Smooth and Quiet Ride: Electric powertrains provide near-silent operation and instant torque, resulting in a smooth and responsive driving experience.
  • Refined Handling: The e-TNGA platform and Direct4 AWD system contribute to confident handling and stability.
  • Luxurious Interior: The RZ 450e offers a well-appointed interior with premium materials and advanced technology.
  • Advanced Technology: Features like the optional Steer-by-Wire system and Lexus Safety System+ 3.0 enhance the driving experience and safety.
  • Zero Emissions: Contributes to environmental sustainability with zero tailpipe emissions.

Cons

  • Range: The range might be considered limited compared to some competitors, particularly in colder climates.
  • Charging Time: Charging times can still be longer compared to filling a gasoline tank, especially with slower charging options.
  • Steer-by-Wire Learning Curve: The Steer-by-Wire system can take some getting used to, as it provides a different steering feel compared to traditional systems.
  • Price: The RZ 450e is positioned as a luxury EV, so it carries a premium price tag.
  • Cargo Space: Cargo capacity may be less than some competitors in the compact SUV segment.

Buying Advice

Given the RZ 450e's recent introduction, your options are limited primarily to recent model years. However, here's what to consider:

Years to Look For

  • 2023 and Newer: These models will offer the latest features and technology. Focus on 2024 models and beyond if you want software refinements addressing any early adopter issues.

What to Avoid (or Be Cautious Of)

  • First Production Units: As with any new model, early production units may be more susceptible to manufacturing defects or software glitches. Thoroughly inspect these vehicles and inquire about any recalls or service bulletins.
  • Used Vehicles with High Mileage: Electric vehicles typically have lower maintenance needs, but high mileage can still indicate potential wear and tear on components like the battery, suspension, and brakes. Request a battery health report.
  • Vehicles with Neglected Maintenance: Even though electric vehicles require less frequent maintenance, neglecting scheduled checks can still lead to problems. Verify the vehicle's service history.
  • Aftermarket Modifications: Be wary of vehicles with aftermarket modifications that could void the warranty or negatively impact performance.

Pre-Purchase Inspection Checklist

  • Battery Health: Obtain a battery health report to assess the battery's capacity and degradation.
  • Charging Functionality: Test both AC and DC charging to ensure proper operation.
  • Software Functionality: Verify that all software features, including the infotainment system and ADAS features, are working correctly.
  • Steer-by-Wire (if equipped): Evaluate the steering feel and responsiveness.
  • Mechanical Inspection: Have a qualified mechanic inspect the suspension, brakes, and other mechanical components.
  • Cosmetic Condition: Inspect the interior and exterior for any damage or signs of wear and tear.
  • Vehicle History Report: Obtain a vehicle history report to check for accidents, title issues, or other problems.
  • Check for Recalls: Verify that all applicable recalls have been performed.

By carefully considering these factors, you can make an informed decision when purchasing a Lexus RZ 450e and enjoy a refined and eco-friendly driving experience.
