• Difficulty starting your vehicle: A slow engine crank, clicking sound, or complete no-start condition may indicate problems with the battery, starter, alternator, or wiring connections.
• Flickering or dim lights: Headlights, interior lights, or dashboard lights that dim or flicker while driving may signal charging system problems or failing electrical components.
• Malfunctioning electronics: Power windows, infotainment systems, backup cameras, climate controls, and other electronic features rely on a healthy electrical system to operate correctly.
