Problem overview

Some Lexus GS300 owners report experiencing speedometer failure, often attributed to issues with the vehicle speed sensor. These owners have noted instances where the speedometer displays incorrect speeds, such as showing 15 mph while stopped or 40 mph while driving, highlighting the importance of addressing these issues promptly to ensure safe driving and compliance with speed limits. Additionally, some owners report experiencing a loss of power steering, which can significantly affect driving safety and maneuverability. This power steering loss may be related to a malfunctioning power steering pump or fluid leaks, making steering more challenging, particularly at lower speeds or during parking maneuvers. If these problems are encountered, it is advisable for owners to have their Lexus GS300 inspected by a qualified mechanic or dealership for diagnosis and necessary repairs. Regular maintenance and prompt attention to these issues are crucial for the safe and reliable operation of the vehicle.
