INFINITI FX37 overheating issue leading to engine shutdown with cylinder codes on INFINITI FX37

Some INFINITI FX37 owners report experiencing overheating issues that can lead to engine shutdown and the triggering of cylinder codes. Common symptoms include high temperature readings on the gauge and potential coolant leaks, which may indicate underlying coolant flow issues or insufficient airflow through the radiator. Additionally, the presence of OBDII code P1217 suggests engine over-temperature, possibly caused by a malfunctioning thermostat, faulty cooling fan, low coolant levels, or a defective water pump. Owners have noted that overheating can result in reduced performance, increased fuel consumption, and potential engine damage. Malfunctions in the cooling system, such as a failing cooling fan, can further exacerbate these overheating problems. Moreover, overheating can trigger cylinder codes like P0301, indicating a number 1 cylinder misfire, which requires prompt attention to avoid further damage. It is crucial for owners experiencing these issues to seek professional assistance for proper diagnosis and repair to ensure vehicle safety and performance.
