Frequently Asked Questions

What is the most common reason for check engine light on a 2026 Dodge Durango?

• Loose or damaged gas cap is a frequent trigger that affects the evaporative emissions system and is simple to fix.
• Faulty oxygen sensors and catalytic converter issues are common on modern V‑6 engines and can affect fuel economy and emissions.
• Ignition misfires (spark plugs, coils) will illuminate the light and may cause performance loss or damage if left unchecked.
• EVAP system leaks, sensors and wiring faults are typical diagnostic findings on crossover and SUV markets like the Durango.
• Bring your 2026 Dodge Durango to our certified technicians so repairs covered by warranty are correctly performed at a dealership.

What does it mean when the check engine light comes on in a 2026 Dodge Durango?

• It signals the powertrain control module detected a fault in emissions, engine management, or related systems that needs diagnosis.
• Severity ranges from minor (sensor or gas cap) to severe (engine misfire, catalytic failure) — the light alone doesn’t show exact cause.
• An illuminated light can reduce fuel economy, increase emissions, and lead to component damage if ignored.
• Diagnostics at Herb Chambers Chrysler Dodge Jeep RAM FIAT of Danvers identify codes precisely and provide immediate and long‑term savings versus repeated independent repairs.
• Remember: any warranty-covered repair must be performed at a certified dealership to preserve coverage and ensure factory-trained service.

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

• Confirm the gas cap is tightened; a loose cap is an easy fix and a frequent culprit on modern vehicles.
• Check for obvious issues — low oil, coolant, or a disconnected intake hose — but avoid guessing with complex systems on the 3.6L V6.

• If the light is flashing, stop driving and have the vehicle inspected immediately to prevent engine or catalytic damage.
