What does it mean when the check engine light comes on in a 2026 Nissan Z?

• It signals the vehicle’s engine control unit detected a fault — anything from a loose gas cap to engine misfires, sensor failures, or emissions issues.
• Codes saved to the vehicle help technicians pinpoint the subsystem affected (fuel, ignition, emissions, or powertrain timing).
• Ignoring the light can reduce performance and MPG (19 city / 28 highway) and may lead to more expensive repairs later; our service approach emphasizes immediate fixes that save money long term.
• Repairs covered under warranty must be done at a certified dealership to maintain protection and ensure proper parts and calibration.

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

• Check for an obvious issue: a loose or missing gas cap, dashboard alerts, or sudden changes in drivability.
• For accurate diagnosis, have our technicians perform an OBD-II scan to read stored codes rather than guessing; this reduces unnecessary parts replacement and saves money.
• If the vehicle is covered by warranty, remember warranty repairs and diagnostics need completion at a certified dealership to remain valid.
