Problem overview

Some Genesis G80 owners report experiencing engine overheating issues due to various factors, including insufficient coolant levels or leaks from components like hoses or the radiator. Additionally, a malfunctioning thermostat that fails to regulate coolant flow can contribute to overheating, as can a clogged radiator that obstructs proper heat dissipation. Some owners have noted that faulty cooling fans may not adequately cool the engine, leading to increased temperatures. Symptoms of a bad thermostat, such as no heat or a spiked temperature gauge, can also indicate potential problems. The reliability of Genesis G80 models varies by year and engine type, with earlier models reportedly facing more issues than later ones. Owners are advised to monitor the engine temperature gauge and have diagnostic codes checked to identify underlying problems. If overheating persists, consulting a professional mechanic or dealership for further diagnosis and repair is recommended.
