The oil cooler on this engine sits between the oil and coolant passages, so an internal failure of that component mixes the two systems. The failure first occurred in September 2025 while the vehicle was in use, and coolant intrusion into the oil system has recurred in 2026.  This condition is a safety concern because it can cause engine overheating and sudden loss of engine performance or engine failure while driving. On one occasion the vehicle overheated within approximately one mile of leaving a service facility. Low oil pressure was also observed (as low as 9 psi), which risks engine damage and loss of power in traffic.  The manufacturer (FCA US LLC / Stellantis) initial XXX November 7, 2025 the arbitrator ruled in my favor, finding the oil cooling system failure \"was more likely a result of a Manufacturer defect\" and that my modifications \"did not cause the oil cooling system failure,\" and ordered the manufacturer to repair it. FCA's own [XXX] owner dashboard showed the Powertrain Limited Warranty active (expiration 10/07/2026 or 100,000 miles) as recently as May 18, 2026; yet by XXX a Stellantis dealership reported the vehicle under a complete vehicle restriction and refused to diagnose it, leaving a known engine defect unrepaired.  I am reporting this so the potential safety defect in the EcoDiesel oil cooler and the resulting engine overheating and failure risk are on record, and because the manufacturer has not repaired a defect that an arbitrator determined to be a manufacturing defect.
