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

• Check the gas cap: a loose or damaged cap is a common trigger and is easy to fix.
• Note vehicle behavior: loss of power, strange noises, or poor idling indicates higher urgency.
• Inspect visible items: fluid levels, disconnected hoses, or obvious leaks if safe to do so.
• Even after simple fixes, have a dealership scan the codes — certified service ensures warranty protection and prevents hidden issues from escalating.

What is the most common reason for check engine light on a 2026 Toyota Corolla Cross?

• The most frequent cause is a loose or faulty gas cap that allows fuel vapors to escape and triggers EVAP system codes.
• Other common issues include oxygen sensor failures, faulty spark plugs or coils, and EVAP system leaks; addressing them early avoids further damage.
• Left untreated, these issues often lead to higher fuel use, failed emissions tests, or catalytic converter damage that increases repair cost significantly.
• We recommend a dealership diagnostic to confirm root cause and preserve warranty eligibility when repairs are needed.

How long does a check engine light service take?

• Simple code reads can take 15–30 minutes; a full diagnostic typically requires 1–2 hours depending on the issue.
• Minor repairs, like tightening a gas cap or replacing a sensor, may be completed the same day; complex repairs take longer and will be scheduled with you.
• Our factory-trained technicians and OEM diagnostic tools speed accurate diagnosis and reduce repeat visits, saving you time and money in the long run.
• Remember: warranty-covered repairs must be completed at a certified dealership to maintain coverage — we prioritize fast, warranty-compliant service.
