Frequently Asked Questions

What is the most common reason for check engine light on a 2024 Mercedes-Benz GLC-Class?

• Loose or damaged gas cap is the simplest and most frequent cause; it often triggers an evaporative emissions code.
• Faulty oxygen sensor or catalytic converter issues are common as the vehicle ages and can affect emissions and fuel economy.
• Ignition misfires (spark plugs, coils) create driveability problems and must be inspected promptly to avoid engine damage.
• Electronic sensor faults (mass airflow, cam/crank sensors) can trigger codes even if performance seems normal.
• Bring the vehicle to Park Place Motorcars Fort Worth for a precise diagnosis; factory-trained technicians identify the root cause and explain repair costs and warranty coverage.
