Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2026 Toyota GR Supra MkV?

• Check basics first: ensure the gas cap is tightly secured — a loose cap is a common, low-cost cause and is easy to fix.
• Confirm recent events: did you use lower-grade fuel, run very low on fuel, or notice unusual noises or smells?
• Inspect obvious visual signs: look for disconnected hoses, fluid leaks, or a damaged air intake—these can trigger a code.
• If the light persists, bring the 2026 Toyota GR Supra MkV to Coggin Toyota at the Avenues for a factory diagnostic to protect warranties and avoid escalation.

How long does a check engine light service take?

• Standard diagnostics typically take 30–60 minutes: our technicians scan codes, test components, and provide a clear report.
• Minor fixes (e.g., tightening a gas cap or replacing a sensor) are often completed the same day.
• Complex repairs or parts orders may extend service; we communicate timelines and work to minimize downtime.
• Choosing Coggin Toyota at the Avenues often saves time and money—factory-trained techs and genuine parts mean fewer repeat visits and long-term savings.
