Frequently Asked Questions

What is the most common reason for check engine light on a 2023 Alfa Romeo Stelvio?

• Loose or faulty gas cap — a quick, common cause that can trigger an emissions fault and illuminate the light.
• Oxygen sensor or catalytic converter issues — sensors that affect fuel mixture and emissions are frequent culprits.
• Ignition or fuel system faults — worn spark plugs, coils, or injectors can set codes and reduce performance.
• Turbocharger-related sensors — the Stelvio’s turbo system uses sensors that, when failing, often set fault codes.
