NHTSA complaint #11758412

Owner complaint summary

My 2019 Chrysler Pacifica Touring L Plus is experiencing coolant leaking into a cylinder, diagnosed by. This has rendered the vehicle undrivable. The Pentastar 3.6L V6 engine used in this vehicle has a well-documented pattern of coolant intrusion into cylinders due to head gasket failure across the 2017–2019 Chrysler Pacifica model years, based on extensive owner complaints already on file with NHTSA and reported by consumer advocacy organizations. Despite this known pattern, no recall currently exists covering this specific defect for 2019 model year vehicles. This is a safety concern because coolant intrusion into a cylinder can cause sudden misfires, rough running, loss of power, and potential stalling while driving — creating a hazard in traffic, particularly at highway speeds or during turns/merges. I contacted Chrysler Case Management regarding this issue. The manufacturer has attempted to attribute responsibility to the dealership rather than acknowledging this as a manufacturer defect in the engine design/manufacturing, despite the well-documented pattern across multiple model years of the same engine. I have also not been provided a rental vehicle despite my vehicle being undrivable.
