Frequently Asked Questions

Why is a battery important for a 2019 Hyundai Sonata Plug-in Hybrid?

• The battery powers both the 12V electrical systems and the high-voltage traction system that provides the vehicle's electric range; maintaining it preserves fuel economy and the factory 28-mile electric range.
• Proper battery health prevents unexpected roadside failures and preserves the longevity of hybrid components; Arapahoe Hyundai's factory-trained technicians use diagnostic tools to detect early wear and optimize performance.

How long does a battery replacement take?
