Frequently Asked Questions

Why is a battery important for a 2025 Toyota GR86?

• Provides the primary electrical power to start the engine and energize the starter motor and ignition system so the car runs reliably every time.
• Powers electronic control units (ECUs), safety systems, and sensors—ensuring traction control, airbags, ABS, and engine management operate correctly.
• Supports accessory systems (infotainment, lighting, climate controls) when the engine is off and stabilizes voltage while the alternator is active to protect sensitive electronics.
• A weak or failing battery can cause hard starts, dim lights, erratic electronics or fault codes that affect performance and fuel economy, especially in a performance-oriented coupe like the 2025 Toyota GR86.
• Certified dealership battery checks and replacements help preserve warranty coverage and long-term value—repairs covered under warranty must be performed at a certified dealership to remain valid.
