ENGINE COOLANT PUMP: The electrical connector of the engine coolant pump could become damaged. Small drops of liquid from the positive crankcase ventilation (PCV) system could drip down onto the electrical connector of the pump. Safety Risk Over time, this could lead to a short circuit and, in rare cases, a thermal event or a fire. We took it to a car shop and they charged us over $800 fixing something else that was not the issue. We havent been able to drive this car for months and it has caused tremendous inconveniences.
