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

• Start with the gas cap— a loose or damaged cap is a common and easy fix that can trigger the light.
• Check for obvious symptoms like loss of power, unusual noises, smoke, or fluid leaks and report them to the technician.
• Even if the car seems to run normally, bring it in for a scan rather than resetting the light yourself; an unresolved fault can worsen.
• Warranty-covered repairs must be completed at a certified dealership; our factory-trained technicians ensure proper documentation and repair quality.
