Problem overview

Some INFINITI QX30 owners report experiencing coolant leakage issues due to common causes such as damaged hoses, faulty water pumps, radiator leaks, blown head gaskets, or broken serpentine belts. Symptoms of these leaks may include low coolant levels, an overheating engine, a coolant odor, or visible puddles of coolant under the vehicle. To prevent these problems, it is recommended that owners regularly check the coolant level, especially during routine services, as some evaporation is normal for QX30 vehicles. Promptly addressing coolant leaks is crucial to avoid overheating and engine damage, with effective repairs typically involving the identification of the leak's source and replacement of damaged components. If a coolant leakage issue is suspected, it is advisable for owners to have their vehicle inspected by a certified mechanic to prevent potential damage.
