Frequently Asked Questions

What is the most common reason for check engine light on a 2017 Mercedes-Benz GLC-Class?

• Loose or faulty gas cap — a simple seal issue can trigger the light and is often resolved quickly and affordably.
• Oxygen sensor or catalyst efficiency faults — these affect emissions and fuel economy, and demand timely repair to avoid larger bills.
• Ignition misfires (spark plugs, coils) — can lead to engine damage if left unaddressed; diagnosis by factory-trained techs pinpoints the exact cause.
• Software or sensor faults — modern Mercedes vehicles rely on sensors and ECU updates; our certified dealership has the correct diagnostic tools and software access.
