What does it mean when a steering wheel icon appears on the dashboard?

A steering wheel icon appearing on the dashboard indicates a malfunction in the vehicle's power steering system, which requires immediate repair. All modern vehicles are equipped with power steering systems, with three common types: electric power steering (EPS), electro-hydraulic power steering (EHPS), and mechanical hydraulic power steering (MHPS). The EPS system operates without hydraulic components, relying solely on an electric motor to provide steering assistance. Both EHPS and MHPS systems incorporate hydraulic mechanisms and utilize power steering pumps. For hydraulic-based systems, regular replacement of power steering fluid is essential to prevent steering wheel stiffness. During routine maintenance, it's crucial to periodically inspect the power steering system's functionality. Any detected damage to the system should be repaired promptly.
Last time, a steering wheel icon popped up on my car's dashboard, and my heart skipped a beat—it's a warning signal indicating a power steering system malfunction. Common causes include low steering fluid levels or sensor issues; if the fluid level is low, the steering wheel will become harder to turn, especially at low speeds when parking. You should pull over immediately to check the fluid reservoir, usually located in the engine compartment—open it up and see if the fluid is low, then top it up with some steering fluid. Sometimes, it's an electronic system failure, like a short circuit, which requires a visit to the repair shop for a computer diagnosis. Never ignore it, as it could lead to an accident. I once experienced this myself and was lucky to get it fixed in time. Developing a habit of glancing at the dashboard before driving can help avoid major issues.
