The rear window (backlite) has a known manufacturing defect that allows water intrusion, potentially damaging the RF hub and creating conditions conducive to mold growth (see TSB 23-098-23). My vehicle has been affected by this defect, yet FCA has only extended the warranty to select vehicles, excluding others of the same year, make, and model that are clearly impacted by the same issue. This defect has led to saturated floor boards/carpet under the rear seats and has lead to the growth of mold.
