Maintenance & Warranty
Recommended Lexus RX Service Intervals
Toyota Motor Corporation-recommended 10K interval with 0W-20 synthetic. Hybrid models use conventional service intervals; battery is 10-year warranty.
"Severe service" conditions (heavy towing, extreme temps, city stop-and-go) typically halve these intervals. Always consult your vehicle's owner's manual for the authoritative schedule.
Lexus New-Vehicle Warranty Coverage
Hybrid battery is now 10yr/150K miles for 2020+ hybrids
These are the terms for a new Lexus. If you're buying a used 2010 RX, remaining coverage is usually pro-rated from the vehicle's original in-service date. Not all coverage transfers between owners — check with a Lexus dealer for VIN-specific remaining warranty.
