Model-year considerations

Generations at a glance

Reliability tends to evolve with redesigns. Here’s a concise look at how different generations have generally fared and what to look for when buying used.

• Earlier generations (pre-2020 redesign) are typically dependable, but some model years show electronics and refinement differences as the platform aged. A thorough inspection and service history are especially important for higher-mileage examples.


• The redesigned RX introduced for the 2020 model year brought updated electronics, infotainment refinements, and broader availability of newer safety features, contributing to improved reliability in recent years.

For buyers seeking the most consistent reliability, choosing a well-documented, lower-mileage example from the latest generation is usually the safest bet.

Ownership costs and value retention

Reliability also intersects with ownership costs: predictable maintenance and strong resale value often shape a buyer’s long-term experience.

• Maintenance costs for the RX350 are generally in line with other premium SUVs, focusing on routine services, tires, brakes, and periodic replacements.


• Resale value remains a strong selling point, with RX models commonly retaining substantial value relative to competitors in the luxury SUV segment.


• Warranty coverage and dealer support help keep repair expenses manageable during the early years of ownership, contributing to a favorable total cost of ownership for many buyers.

Overall, the RX350’s blend of reliability and value retention makes it a compelling option for buyers prioritizing long-term durability and predictable ownership costs.

Summary

In summary, the Lexus RX350 is widely regarded as a reliable luxury SUV, backed by Toyota’s engineering, a durable powertrain, and a robust service network. While individual results vary by model year and maintenance history, owners typically report strong long-term durability, few unexpected repairs, and solid resale value. Prospective buyers should verify a complete maintenance history and conduct a thorough pre-purchase inspection to confirm reliability for a specific vehicle.

How many miles does a Lexus RX 350 last?

A Lexus RX 350 can last anywhere from 250,000 to over 300,000 miles, and sometimes even 400,000 miles, with proper and consistent maintenance. While its lifespan can exceed 300,000 miles, many drivers consider purchasing a used model with 100,000 to 150,000 miles, especially if it has a strong service history. 
Factors affecting lifespan

• Maintenance: Following the recommended maintenance schedule is the most critical factor for longevity. 
• Build quality: Lexus vehicles are known for their reliability, which contributes to their long lifespan, according to Ray Catena Lexus and PA Auto Sales. 
• Driving conditions: The vehicle's lifespan can be affected by how it's driven, such as city vs. highway driving, and the climate it operates in. 
• Model year: Some model years may have specific issues, such as the oil leak complaints on some 2007-2010 models. 

How to maximize your RX 350's lifespan

• Keep up with routine maintenance: Perform regular oil changes and other scheduled services. 
• Check for recalls: Be aware of any manufacturer recalls, such as the oil hose recall, and address them promptly. 
• Get a pre-purchase inspection: Before buying a used RX 350, have an independent mechanic inspect it to identify any potential problems. 
• Consider a used model with lower mileage: If you're looking for a used car, consider one with a good service record and a lower mileage, such as under 150,000 miles. 

What is the most common problem with Lexus RX350?

The most common problem with the Lexus RX 350 is a massive oil leak, specifically from the VVT-i oil line, which can lead to rapid oil loss and potential engine failure, especially in older models like the 2010. Other frequent issues include faulty rain sensors, especially in newer models, resulting in wipers that malfunction randomly. Older model years (2007 and 2010) also show a tendency for airbag warning lights and transmission problems, while some 2016 models experienced rough shifting and transmission issues.
