Frequently Asked Questions

What is the most common reason for check engine light on a 2026 Jeep Compass?

• Often a loose or damaged gas cap triggers the light by causing an EVAP system leak; it’s a quick, low-cost fix if addressed early.
• Faulty oxygen sensors, ignition coils, or spark plugs are frequent causes that affect fuel economy and emissions if left untreated.
• EVAP leaks, catalytic converter inefficiency, and intermittent misfires can escalate into costly repairs and reduced performance.
• Our dealership’s technicians use factory diagnostics to pinpoint the root cause, helping you avoid unnecessary parts replacement and long-term expenses.
• Remember: repairs covered under warranty must be performed at a certified dealership to preserve coverage and maximize long-term savings.

What does it mean when the check engine light comes on in a 2026 Jeep Compass?

• A steady light signals a stored fault in the emissions, ignition, fuel, or sensor systems; it needs a diagnostic scan to identify codes.
• A flashing light usually indicates a severe misfire that can damage the catalytic converter—avoid driving and seek immediate service.
• Some triggers are minor (e.g., loose gas cap) while others require immediate repair to prevent engine or emissions system damage.
• Our certified technicians perform a full scan and explain short- and long-term costs so you can make an informed decision.

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

• Start with the gas cap: ensure it’s tightened properly and check for visible damage; a reseated cap often clears EVAP codes.
• Look for additional dashboard warnings or abnormal engine behavior—rough idle, stalling, or loss of power indicate urgency.
• Do not ignore a flashing light; reduce speed and have the vehicle inspected to avoid serious damage like catalytic converter failure.
