Vehicle stalled while driving. upon inspection by the dealership, i was informed that a coolant valve connected to the transmission control module had failed. this resulted in coolant leaking into the module and thereby damaging it. this is a known defect in a similar vehicle of the same year.
Check engine light came on so i took it to the dealership. dealership told me that the "coolant valve leaked into the wiring harness and shorted the engine control module. may have cause an unexpected stall of the vehicle."
