A mechanic has identified this assembly as the source of the oil leak and confirmed that its failure is allowing engine oil to mix with the coolant.  In addition to internal oil and coolant contamination, engine oil is leaking externally onto surrounding engine components, potentially including the serpentine belt and pulley system.  The vehicle recently experienced a complete serpentine belt failure while driving, resulting in engine overheating and requiring me to pull over immediately to prevent additional engine damage. I am concerned that oil leaking from the housing assembly may have contributed to the premature deterioration and failure of the serpentine belt.  The oil contamination of the cooling system presents additional safety concerns, including reduced cooling efficiency, damage to cooling system components, and the possibility of severe engine damage or unexpected vehicle disablement.  The combined risks of external oil leakage, internal coolant contamination, serpentine belt failure, and engine overheating create a potentially dangerous situation, particularly during highway driving.  I am concerned that the oil filter housing/oil cooler assembly may have an underlying design or manufacturing defect. I am requesting that NHTSA investigate this issue in 2021 Jeep Grand Cherokee vehicles equipped with the 3.6L Pentastar engine and determine whether a safety recall or other corrective action is warranted.","products":[{"type":"Vehicle","productYear":"2021","productMake":"JEEP","productModel":"GRAND CHEROKEE","manufacturer":"Chrysler (FCA US, LLC)"}]}]}
