What are signs of a failing power steering system?

A failing power steering system often manifests through specific symptoms that are both audible and tactile. When a driver notices a whining noise while turning the steering wheel, it typically indicates that the power steering fluid might be low or that there could be a problem with the power steering pump itself. Additionally, difficulty steering—such as feeling heavy resistance or unresponsiveness when attempting to turn the wheel—further signifies an issue with the power steering system. These signs are critical indicators that prompt a closer inspection of the power steering system, as they indicate that it may be unable to assist in steering as designed, leading to potential safety hazards if not addressed.

The other options, while they may indicate problems with the vehicle, do not specifically relate to the power steering system. Excessive loud engine noise at high speeds generally pertains to engine issues, increased tire wear and tear is often linked to alignment or suspension problems, and frequent dashboard warning lights could indicate a range of electrical or engine malfunctions, but not necessarily the power steering system directly.
