Is the Lexus RX 350 reliable?

Yes. The RX 350 is broadly regarded as one of the most reliable vehicles in its class, earning strong dependability scores from major rating agencies and typically low maintenance costs when properly serviced.

What reliability means for the RX 350

The question of reliability covers long-term performance, maintenance costs, and how the model compares with rivals across model years. For the RX 350, the answer depends on generation (fourth generation since 2023 uses a turbocharged four-cylinder, while earlier generations used a V6) and ownership history. The overview below reflects the current landscape through 2024–2025.

What experts say

Industry trackers and consumer-safety organizations regularly rate Lexus products, including the RX line, near the top for dependability. Here are the broad takeaways from those evaluations:

• Consistently high reliability scores from Consumer Reports and J.D. Power for Lexus SUVs, including the RX family.


• Strong resale value, which often correlates with durable reliability and satisfied ownership experiences.


• Robust powertrain engineering across generations, with Lexus reputation for longevity and relatively low maintenance costs compared with many peers.


• Quiet, well-built interiors and reliable electronics that contribute to an overall trouble-free ownership experience.


• Extensive dealer networks and comprehensive warranties that can reduce ownership friction.

These assessments reflect typical owner experiences and manufacturer engineering, though individual results can vary by model year and maintenance history.

What to watch for

There are caveats and year-to-year variations. The RX 350’s more recent generation uses a turbocharged four-cylinder engine, which can bring different maintenance considerations than the older V6. Hybrid variants add complexity with additional components. Some owners report infotainment glitches or recalls on certain model years, though most issues are resolved via updates or recall campaigns.

• New powertrain in 2023+ models (2.4L turbo) may have early-production teething issues; ensure dealer-installed software updates and monitor for unusual oil consumption patterns.


• Infotainment and electronics: occasional glitches or latency reported in some model years, typically addressed by firmware updates.


• Recalls or service campaigns: verify recall status for a specific VIN before purchase, as with any used vehicle.


• Maintenance costs: generally favorable for a luxury SUV, but costs can rise after the warranty expires; synthetic oil changes and recommended service intervals should be followed.

Overall, most owners report reliable performance with routine maintenance, though any used vehicle should be checked for service history and outstanding recalls.

Maintenance and ownership considerations

Putting reliability into practice involves disciplined upkeep. The RX 350’s cost of ownership tends to be favorable among midsize luxury SUVs, particularly when serviced at authorized centers and with original parts. The following guidance helps buyers maximize reliability and minimize surprises.

• Follow the manufacturer maintenance schedule, using recommended fluids and parts.


• Keep thorough service records to establish a trusted maintenance history.


• Address recalls promptly via a Toyota/Lexus dealer to avoid safety or reliability issues.


• Choose certified pre-owned options with remaining warranty or opt for extended coverage if buying used.


• Regular checks on tires, brakes, and battery health can prevent unexpected failures.

Proper maintenance and careful selection of a well-documented vehicle are the best predictors of long-term reliability for the RX 350.

Bottom line and what to consider before buying

For most buyers, the Lexus RX 350 remains a reliable, comfortable, and practical choice in the midsize luxury SUV segment. Pros include strong reliability history, resale value, and a refined ownership experience. Prospective buyers should weigh engine type (V6 in older models vs turbocharged four-cylinder in the latest generation), hybrid options, and the vehicle’s maintenance history. A pre-purchase inspection by a qualified technician remains essential for any used purchase.

Summary

The Lexus RX 350 stands among the most dependable options in its class, supported by Lexus engineering, solid resale values, and generally manageable maintenance costs when cared for properly. As with any vehicle, reliability hinges on consistent servicing, prompt recall handling, and choosing a well-documented used example. Overall, it is a dependable choice for buyers prioritizing long-term reliability.

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.
