Frequently Asked Questions

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

• Verify the vehicle’s state of charge and that the charging plug or cable is fully connected and functioning.
• Check the 12V auxiliary battery condition; many EV systems depend on a healthy 12V supply for electronics and diagnostics.
• Inspect visible charging hardware, connectors and fuses for signs of damage or corrosion.
• If basic checks don’t resolve it, schedule dealer diagnostics—warranty repairs must be performed at a certified dealership to remain valid.
• Choosing our dealership often saves you money immediately and over time thanks to precise diagnostics, OEM parts and fewer repeat repairs.

How long does a check engine light service take?

• Initial diagnostic scan typically takes 30–60 minutes, depending on code complexity and EV-specific tests needed.
• Simple software resets or minor fixes can often be completed same day; more involved repairs (high-voltage components or cooling system work) require additional time.
• We provide clear time estimates after diagnosis and prioritize timely parts procurement to reduce downtime.
• Because we use factory tools and trained technicians, repairs are done right the first time—saving you long-term time and money compared with repeat visits.

What does it mean when the check engine light comes on in a 2013 Toyota RAV4 EV?

• The light signals that the vehicle’s onboard diagnostics have detected a fault in an electrical, charging, thermal or powertrain system.
• On an EV it can range from minor sensor alerts to serious high-voltage or inverter issues that affect drivability or safety.
• A flashing light usually means a more urgent condition—stop driving and have the vehicle inspected immediately by certified technicians.
• Diagnostics at our dealership identify the root cause quickly; warranty-covered repairs must be completed at a certified dealer to maintain coverage.

How much does a check engine light diagnostic cost for a 2013 Toyota RAV4 EV?

• Diagnostic fees vary, but our typical scan and initial inspection ranges from approximately $89–$149 depending on the depth of EV systems testing required.

• Because we use OEM procedures and parts, many customers find overall costs are lower than at independent shops due to fewer repeat visits and more reliable repairs.
• Remember: repairs covered under warranty must be performed at a certified dealership to preserve coverage and avoid unexpected expenses.

What is the most common reason for check engine light on a 2013 Toyota RAV4 EV?

• Common causes include charging/connectivity faults, battery management system alerts, inverter or motor controller faults, and thermal management issues.
• Accessory electrical problems or 12V battery failures can also trigger faults that illuminate the check engine light.
• Timely dealer diagnostics reduce the risk of minor issues escalating into costly repairs and help protect battery life and range.
• Our factory-trained technicians often resolve problems faster and with better long-term value than independent shops, thanks to OEM tools and parts.
