Frequently Asked Questions

What is the most common reason for check engine light on a 2024 Acura RDX?

• Evaporative emissions system issues (loose or damaged gas cap, EVAP leaks) are frequent and simple to fix.
• Faulty oxygen sensors or mass air flow sensors that affect air/fuel mix and fuel economy.
• Engine misfires from worn spark plugs or ignition coils; left unattended, misfires can harm the catalytic converter.
• Catalytic converter efficiency codes (P0420) can appear after prolonged unresolved engine issues.
• We recommend a professional scan to identify the exact cause and prevent escalation—factory-trained technicians provide fast, accurate diagnosis.

What does it mean when the check engine light comes on in a 2024 Acura RDX?

• It signals that the vehicle’s onboard diagnostics detected a fault—ranging from minor (gas cap) to serious (engine misfire).
• The light can be steady (non-critical) or flashing (urgent); a flashing light suggests immediate attention is required.
• Diagnostic trouble codes (DTCs) stored in the ECU pinpoint system or component faults for targeted repair.
• At Nalley Acura we use genuine Acura diagnostic tools and OEM parts to restore performance and protect long-term value.
• Remember: repairs covered under warranty must be completed at a certified dealership to preserve coverage.

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

• Confirm stability: note any drivability changes (loss of power, rough idle, stalling) or dashboard warnings.
• Check the gas cap is tightened properly—many lights are triggered by an EVAP system fault caused by a loose cap.
• A quick visual check for leaks, odd smells, or smoke can indicate a serious condition; if present, stop driving and contact us.
• A professional scan at Nalley Acura will reveal DTCs and recommended repairs; warranty-covered fixes must be done at a certified dealer.
• If the light is flashing, arrange immediate service—don’t delay. Towing options are available for safety and to avoid further damage.
