Frequently Asked Questions

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

• Check for simple issues first: loose or damaged gas cap, low fuel level, or recent refueling—these common causes are quick to inspect.
• Look for obvious signs: unusual noises, smoke, loss of power, or extreme drivetrain behavior that suggest immediate towing.
• Use a professional scan: our dealership runs an OBD-II diagnostic to read codes and determine severity accurately.
• Remember warranty requirements: any repair covered under warranty must be completed by a certified dealership to preserve coverage and long-term savings.
