At this mileage, the vehicle is still relatively new. Focus on routine oil changes, tire rotations, and general fluid checks to maintain its excellent early-life reliability.

60,000

Maintenance Zone

This mileage often brings the need for standard wear items like tires and brakes. It's also a good time for transmission fluid service (if not already done) and to start listening for suspension noises.
