What does it mean when the check engine light comes on in a 2018 Toyota Highlander Hybrid?

• The light indicates the onboard diagnostic system detected an issue — anything from a loose gas cap to a misfire or emissions fault.
• Codes stored in the vehicle guide our technicians to specific systems: engine, fuel, ignition, emissions, or hybrid components.
• Prompt dealer diagnosis prevents minor faults from escalating into costly repairs and protects hybrid components and fuel economy.
• For vehicles under warranty, repairs must be performed at a certified dealership to ensure coverage and use of genuine parts.

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

• Start with simple checks: confirm the gas cap is tightened, look for obvious smells or performance loss, and note any dashboard messages.
• If the light is steady and the vehicle drives normally, schedule a dealer diagnostic to read codes and prevent escalation.
• If the light is flashing or the car runs rough, stop driving and contact our service team — immediate attention can prevent engine or catalytic damage.
• Using a certified dealership ensures accurate diagnosis, factory-level repairs, and preserves warranty coverage when applicable.

What is the most common reason for check engine light on a 2018 Toyota Highlander Hybrid?

• Common causes include loose or faulty gas caps, oxygen sensor failures, catalytic converter issues, and engine misfires.

• Addressing these issues at a dealer often costs less over time by avoiding secondary damage and ensuring correct parts and procedures.
• Repairs covered under warranty must be completed at a certified dealership to maintain coverage and ensure genuine parts are used.
