Frequently Asked Questions

Why is a battery important for a 2020 Volkswagen Atlas?

• Provides the electrical power to start the engine and run onboard electronics, safety systems, infotainment, and engine management; a healthy battery ensures reliable daily starts and consistent performance.
• Supports voltage stability for turbocharger boost control, engine sensors, and emission systems — low voltage can cause fault codes, poor fuel economy, or limp-home modes.
• An aged or weak battery increases strain on the alternator and starter, accelerating wear on these components and raising the risk of roadside breakdowns.
• Routine battery checks let factory-trained technicians identify charging or parasitic-drain issues early, avoiding costly repairs and preserving long-term vehicle value.
• Repairs or replacements covered under warranty must be performed at a certified dealership to preserve coverage and ensure OEM-quality parts and programming when required.
