2026_Genesis_G90

Quick Reference Maintenance Checklist

Every 5,000 miles

  • Inspect brakes (pads, rotors, lines) and overall braking system for safety and wear.

Every 15,000–24,000 miles

  • Replace cabin air filter (helps A/C efficiency and cabin air quality). Official manuals and dealer schedules vary between 15K–24K mile replacements depending on conditions.

Every 30,000–36,000 miles

  • Brake fluid service (flush/replace) to maintain brake performance and prevent corrosion.

Every 45,000–60,000 miles

Every 60,000 miles (AWD / transfer case)

  • All-wheel-drive (AWD) transfer case and differential fluid service, if equipped, to keep drivetrain components lubricated and healthy. (Check your exact model’s manual for AWD requirements.)

Around 97,500–100,000 miles

  • Replace spark plugs for reliable ignition performance and optimal fuel economy. Many official dealer schedules cite spark plug replacement around the ~97,500 mile mark.
