Model-year considerations and buying tips

When shopping for a used Lexus 350, consider how model-year differences affect reliability and cost of ownership. Use this guide to help evaluate the options and negotiate with confidence.

• Check the full service history and ensure routine maintenance has been performed on schedule; verify that any recalls or service campaigns have been completed.


• Different generations may have different infotainment and electronics quirks; test all functions to ensure they operate smoothly.


• Inspect wear items typical to age and mileage, such as tires, brakes, suspension components, and exhaust systems, and look for any signs of leaks or abnormal noises.


• For RX 350 models with all-wheel drive, have the AWD system inspected for unusual noises, vibration, or fluid leaks from the transfer case and differentials.


• Consider a Certified Pre-Owned (CPO) Lexus with extended warranty for added peace of mind, especially if buying a higher-mileage example.

Thorough inspection and a documented maintenance history are the best indicators of future reliability when buying a used Lexus 350.

Maintenance timeline and typical service items

Keeping a Lexus 350 running reliably depends on following the manufacturer's maintenance plan and staying ahead of wear items. Use this at-a-glance checklist as a baseline for service intervals.

• Oil and filter changes: follow the manual’s recommended interval, typically every 5,000–7,500 miles (or as indicated by your vehicle’s computer), with approved oil type for the engine.


• Tire rotations and brake inspections: usually recommended every 5,000–7,500 miles or during regular service visits.


• Fluids: coolant, brake fluid, and automatic transmission fluid (where applicable) should be checked and replenished or replaced per the manual.


• Spark plugs: replace per the factory schedule, commonly around 90,000–120,000 miles for many V6 engines in the Lexus 350 lineup.


• Air filters and cabin filters: replace at regular intervals to maintain performance and efficiency.


• Battery and charging system: have the battery tested periodically, especially in extreme climates or on older vehicles.

Adhering to these maintenance steps helps preserve reliability and reduces the risk of unexpected failures.

Summary

In brief, the Lexus 350 remains a highly reliable choice within the luxury segment, known for durable powertrains and solid long-term value. While model-year differences exist and maintenance history matters, well-maintained ES 350 and RX 350 examples frequently deliver many years of trouble-free ownership. For buyers, the keys are thorough pre-purchase checks, up-to-date recalls, and a consistent maintenance record.

Which year to avoid Lexus RX 350?

Years to potentially avoid the Lexus RX 350 include 2007, 2008, 2010, 2016, and 2017, as these models have been associated with more complaints regarding issues like oil leaks, engine problems, transmission failures, and dashboard cracking. These are often the first year of a redesign, or specific model years that experienced known issues.
 
Model years to avoid

• 2007 and 2008: These years may have issues with oil leaks and cracking dashboards. 
• 2010: Known for engine problems and rattling doors. Some models also have oil cooler hose issues that can be replaced with metal lines. 
• 2016 and 2017: These were the first years of the fourth generation and are often cited as problematic. 
  • The 2016 model saw issues with the new 8-speed transmission. 
  • The 2017 model had problems with faulty rain sensors. 

Why these years have issues

• First year of a redesign: New generations often have "bugs" that are worked out in subsequent model years. This is particularly true for the 2016 model year, which was the first in its generation. 
• Known common problems: Specific model years have common problems associated with them, such as the oil leaks in the 2007-2008 models and transmission issues in the 2016 model. 

If you must buy one of these years

• If you choose one of the problematic years, it is especially important to get a pre-purchase inspection from a trusted mechanic. 
• The 2010 model can be made more reliable by replacing the rubber oil cooler hoses with metal ones.
