Frequently Asked Questions

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

• Inspect obvious items first: loose or missing gas cap, low fuel, or recent fueling events that can trigger evaporative codes.
• Check for obvious leaks or smells—burning, coolant, or strong fuel odors indicate you should stop driving and seek service.
• Use a professional scan at our dealership for accurate codes; simple fixes may be same-day, while deeper issues need technician diagnosis.
• Remember: repairs covered under warranty must be performed at a certified dealership to preserve coverage and ensure long-term savings.
