Nissan Maxima exhaust emitting burning smell with possible white smoke issue after prolonged inactivity on Nissan Maxima

Some Nissan Maxima owners report experiencing issues with their exhaust emitting a burning smell and possible white smoke after prolonged inactivity. This white smoke, particularly after the engine has warmed up, may indicate potential internal coolant leaks, often characterized by its dense, persistent nature and sweet odor. In some cases, thick white smoke with a sweet smell could signal antifreeze burning, potentially due to a blown head gasket. Additionally, owners have noted that a burning smell can stem from leaking fluids, such as coolant or brake fluid, dripping onto hot engine parts, or from burning oil, which is typically accompanied by blue smoke and a decrease in oil level. It is advisable for owners experiencing these symptoms to have their Nissan Maxima inspected by a mechanic to diagnose and resolve the underlying issues, as regular maintenance and prompt repairs are crucial for optimal vehicle performance and safety.
