This bulletin applies to 2015 Jeep Grand Cherokee vehicles equipped with a 5.7L or 3.6L engine, built on or after Nov. 16, 2014, and on or before Jan. 17, 2015. The customer may experience a MIL on while driving.

P0455 (EVAP system large leak) or P0456 (EVAP system small leak) may be set in the PCM. The fix involves replacing the evaporative emissions purge valve hose due to a split in the hose that will prevent the system from sealing.

Using a scan tool, verify that all engine systems are functioning as designed. Correct any issues before proceeding further.

Inspect the purge valve hose for any splits. If damage is found, replace the purge valve hose with a new hose.
