When the vehicle's power steering fluid is insufficient, it is usually accompanied by noticeable abnormal noises and changes in operational resistance. If a sharp buzzing sound resembling metal friction is heard when turning the steering wheel, particularly more pronounced during cold starts, this is typically mechanical noise generated by direct friction between components due to inadequate lubrication inside the power steering pump caused by low fluid levels. These phenomena originate from the hydraulic power steering system's inability to generate sufficient oil pressure, resulting in reduced steering assistance. As the critical medium for transmitting hydraulic pressure and providing lubrication, the power steering fluid level must be maintained within the specified range. Should these symptoms arise, promptly replenish with power steering fluid conforming to the manufacturer's specifications to prevent prolonged fluid deficiency from causing pump wear, which may lead to repair costs of 800 to 1500 ringgit. Vehicles equipped with electric power steering systems are exempt from such issues as they operate without hydraulic fluid assistance.
