What is the maintenance interval for a Lexus RX 350?
The maintenance interval for a Lexus RX 350 is managed by Lexus’ Maintenance Minder system. For most modern RX 350 models, an oil and filter change is recommended every 10,000 miles or 12 months under normal driving, with more frequent service if the Minder indicates. Always follow the car’s Minder and the owner's manual for your exact year and trim.
How the Maintenance Minder guides RX 350 service
The maintenance minder uses sensor data and driving conditions to determine when service is due and what items need attention. It can adjust the schedule based on how the vehicle is driven, which means your car may require service more or less often than a fixed mileage interval.
Below is a baseline, typical schedule for recent RX 350 models. Use this as a planning guide; the Minder may show different intervals on your dashboard.
- Oil and filter change: approximately every 10,000 miles or 12 months under normal driving; shorten this interval in severe conditions or if the Minder indicates.
- Tire rotation and inspection: roughly every 5,000–7,500 miles (often aligned with oil changes); rotate to promote even wear and extend tire life.
- Cabin air filter: inspect around 15,000 miles and replace around 30,000 miles or as needed based on conditions.
- Engine air filter: inspect at about 30,000 miles and replace around 60,000 miles, or when conditions warrant.
- Brake system inspection and fluid: have brakes inspected at each service; brake fluid typically flushed every 2 years.
- Cooling system coolant: replacement commonly scheduled around 100,000 miles or 10 years, with checks earlier if the condition warrants.
- Spark plugs: replacement commonly around 100,000 miles on newer RX 350 engines; depends on model year and engine type.
- Transmission/CVT fluid: inspection at around 60,000 miles; replacement per Lexus guidelines, often between 60,000–100,000 miles depending on year and usage.
- Drive belts (if equipped): inspect around 90,000–100,000 miles and replace if signs of wear are present.
Concluding, the Maintenance Minder drives the service schedule, but the above intervals provide a practical baseline to plan maintenance and budgeting. Always verify against your specific model year and trim.

Summary
For most recent Lexus RX 350 models, routine maintenance centers on an oil change every 10,000 miles (12 months) as guided by the Maintenance Minder, with other tasks scheduled at longer intervals or adjusted by driving conditions. Always follow the Minder and your owner’s manual for your exact vehicle, and consult a dealer if you have questions about your specific year or trim.
