Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2025 Toyota RAV4 Plug-In Hybrid?

• Check for obvious issues first: ensure the charging cable is connected securely (for plug-in operation) and confirm the fuel cap is tightened—these simple items often trigger a light.
• Look for dashboard messages or reduced-power warnings; if present, stop driving and contact our service team right away.
• Note recent fueling, fueling station issues, or smells—these clues help our technicians diagnose faster and reduce repair time and cost.
• Remember: repairs covered under warranty must be performed at a certified dealership to preserve coverage and maximize long-term savings.

How long does a check engine light service take?

• Basic diagnostics—reading trouble codes and a technician assessment—typically take 30–90 minutes depending on complexity and technician availability.
• Simple repairs, such as tightening a gas cap or replacing a sensor, can often be completed the same day.
• More involved fixes (ignition, catalytic converter, hybrid-system work) may require parts ordering or extended diagnostic testing—these can take one to several days.
• At Toyota of Greenville we use factory diagnostic tools and factory-trained technicians to speed accurate diagnosis, often costing less overall than independent shops through quicker fixes and reduced follow-up visits.

• Causes range from simple (evap leak, loose gas cap) to serious (misfire, catalytic converter efficiency, high-voltage hybrid components).
• Early diagnosis prevents costly downstream damage—addressing codes promptly reduces repair expense and protects vehicle value.
• Warranty-covered repairs must be completed at a certified dealership to ensure proper parts, calibration, and long-term savings.
