Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2024 Toyota Grand Highlander Hybrid?

• Check for an obvious issue first: a loose or damaged gas cap can trigger the light. Tighten the cap until it clicks and monitor for changes.
• Inspect for dashboard alerts that accompany the light (battery, HVAC, or hybrid system warnings) and note any changes in drivability.
• If the vehicle runs normally, schedule a diagnostic—delaying may turn a simple fix into a more expensive repair.
• Remember: repairs covered under warranty must be performed at a certified dealership to retain coverage and ensure correct hybrid-system work.

How long does a check engine light service take?

• Initial diagnostic scan typically takes 30–60 minutes to read stored codes, check live data, and assess immediate faults.
• Simple repairs (gas cap, sensor replacement) can often be completed the same day, while more complex repairs may require parts and additional time.
• Our dealership uses factory-trained technicians and OEM tools to provide accurate repairs quickly; that efficiency often means lower overall cost than independent shops.
• If a warranty repair is needed, completing service at our certified dealership ensures coverage and expedited parts sourcing.

What does it mean when the check engine light comes on in a 2024 Toyota Grand Highlander Hybrid?

• The light signals that the vehicle’s computer detected a fault—anything from a minor emissions issue to a significant engine or hybrid system fault.
• It can indicate fuel, ignition, emission controls, or hybrid battery/performance issues; the exact meaning comes from diagnostic trouble codes (DTCs).
• Addressing the issue promptly prevents further damage and protects fuel economy, emissions systems, and long-term ownership costs.
• For warranty-covered issues, repairs must be completed at a certified dealership to maintain coverage and receive factory support.

How much does a check engine light diagnostic cost for a 2024 Toyota Grand Highlander Hybrid?

• Diagnostic fees typically range from about $90–$200 depending on time and complexity, but exact pricing varies by inspection needs.
• Our dealership frequently delivers immediate and long-term savings by combining accurate diagnostics with factory parts and efficient repair workflows—often costing less than independent shops over time.
• If the repair is covered by warranty, work must be performed at a certified dealership; this protects you from out-of-pocket charges and preserves coverage.
• Check our service specials for seasonal offers and diagnostic promotions that further reduce out‑of‑pocket cost.

What is the most common reason for check engine light on a 2024 Toyota Grand Highlander Hybrid?
