Frequently Asked Questions

Why is a battery important for a 2020 Hyundai Sonata Hybrid?

• Power delivery: The 2020 Hyundai Sonata Hybrid relies on both a high-voltage battery for hybrid drive assist and a 12V battery for accessories and start-up systems — both are critical to reliable operation.
• Efficiency and performance: A healthy battery helps maintain the hybrid system’s fuel efficiency and smooth transition between electric and gas power, protecting fuel economy estimates like the Sonata Hybrid’s high MPG performance.
• Dealership advantage: At Arapahoe Hyundai in CO, certified technicians use OEM-grade diagnostics and parts to preserve system integrity — often costing less than independent shops when you factor in longevity, warranty coverage, and fewer repeat repairs.
• Peace of mind: We offer service financing so you can get the repair now and pay later. To book, schedule service or check our service specials.
