Frequently Asked Questions

What is the first thing to check when the check engine light comes on?

• Safely pull over and note any unusual noises, smoke, or loss of power.
• Check the gas cap for tightness — a loose cap is a common, simple cause.
• Look for obvious fluid leaks or dashboard alerts (battery, oil, temperature).
• If the light is steady and the car drives normally, schedule a diagnostic; if flashing, stop driving and have it inspected immediately.
• For warranty-covered issues, repairs must be performed at a certified dealership to preserve coverage and ensure proper recalibration.
