Lexus LS400 overheating issue leading to engine shutdown while driving on Lexus LS400

Some Lexus LS400 owners report experiencing overheating issues that can lead to engine shutdown while driving, which necessitates prompt attention to avoid severe engine damage. These owners have noted symptoms such as dashboard warning lights and steam emerging from under the hood, indicating the need for immediate action. A common cause of overheating in these vehicles is low coolant levels, which are essential for regulating engine temperature.
