P0442 on Your 2024 Dodge Durango
A P0442 code on your 2024 Dodge Durango points to a small evaporative emission system leak. On a brand-new three-row SUV, this is typically something minor — and your warranty covers the repair completely.
EVAP System Overview
The 2024 Durango continues with Stellantis's NVLD (Natural Vacuum Leak Detection) system for EVAP monitoring. Whether equipped with the 3.6L Pentastar V6 or 5.7L HEMI V8, the system uses natural vacuum changes to detect leaks. The purge solenoid, charcoal canister, and fuel tank pressure sensor complete the EVAP circuit.
Likely Causes
- Gas cap not fully seated (45%) — The most common trigger. Ensure the cap clicks firmly.
- Gasket contamination (20%) — Debris on the gas cap seal preventing proper closure.
- Factory EVAP connection issue (15%) — A vapor line fitting that vibrated loose during early driving.
- NVLD device defect (10%) — A rare factory defect in the leak detection system.
- Purge solenoid defect (10%) — A manufacturing seal imperfection.
Recommended Action
Check and reseat your gas cap. If the code persists, schedule a warranty appointment. The dealer's wiTECH system provides comprehensive NVLD diagnostics. All repairs on a 2024 model are warranty-covered.
