Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2025 Toyota Corolla Hybrid?

• Look for obvious signs: a loose or damaged gas cap can trigger the light. Ensure the cap is seated and tightened until it clicks.
• Check basic indicators: verify fuel level, engine noise, unusual smells, or visible leaks before driving further.
• If the vehicle runs normally and the light is steady, schedule a diagnostic at Nalley Toyota Stonecrest to confirm codes and necessary repairs.
• For any warranty-covered repairs, have the work performed at a certified dealership to preserve coverage and ensure OEM parts and factory-trained technicians handle the job.
• Using our dealership often delivers immediate and long-term savings compared with independent shops thanks to accurate diagnosis and fewer repeat visits.

How long does a check engine light service take?

• Initial diagnostic scan typically takes 30–60 minutes to retrieve codes and perform basic checks with OEM-grade equipment.

• The light indicates the vehicle’s onboard computer detected a fault in emissions, fuel, ignition, or hybrid systems; it does not always mean an immediate breakdown.
• A steady light usually signals a non-emergency issue that still needs prompt attention to avoid fuel economy loss or emissions failure.
• A flashing light is more urgent and may indicate a misfire or condition that can damage the catalytic converter—stop driving and have the vehicle inspected right away.
• Diagnostics and repairs performed at our certified dealership protect warranty coverage and often cost less over time due to accurate fixes and OEM parts.
