Maintaining the engine of your 2023 Hyundai Sonata Hybrid is essential to ensure optimal performance and longevity. Hyundai has designed a comprehensive maintenance schedule tailored specifically to the hybrid engine, combining traditional engine care with hybrid system checks.

Key Maintenance Intervals

  • Oil and Filter Change: Every 7,500 miles or 12 months, whichever comes first. Using the recommended synthetic oil helps keep the hybrid engine running smoothly.
  • Hybrid System Inspection: Conducted every 15,000 miles to ensure the battery and electric components are functioning properly.
  • Air Filter Replacement: Replace every 30,000 miles or as needed to maintain airflow and engine efficiency.
  • Brake System Check: Since the hybrid uses regenerative braking, regular inspections every 15,000 miles help maintain safety and performance.
  • Coolant Replacement: The engine coolant and hybrid battery coolant should be checked and replaced every 60,000 miles.

Tips for Longevity

Besides following the scheduled maintenance, keep an eye on any warning lights related to the hybrid system. Regularly check tire pressure and fluid levels, as these can impact fuel efficiency and engine health. Always use genuine Hyundai parts and fluids for replacements to maintain warranty coverage and engine integrity.

By adhering to the Everyday Hyundai maintenance schedule, your 2023 Sonata Hybrid’s engine will continue to deliver reliable, efficient performance for years to come.
