The intermittent soft-then-hard feeling in your EPS is usually a designed speed-based feature or an early warning sign of an electrical issue. Here’s what's likely happening:

· Normal Speed-Sensitive Steering: This is the most likely reason. Your EPS is programmed to provide more assistance (soft feel) at low speeds for easy parking, and less assistance (firm feel) at high speeds for stability and safety. The "sudden" change might just be a delayed reaction to your speed, or a result of selecting a different driving mode (like Sport vs. Comfort).
· Potential Electrical Fault: If this feels random or is accompanied by vibration or error lights, it points to a problem. An intermittent fault often stems from a loose, corroded, or damaged wiring connector to the EPS motor or control unit. Even a shaky connection can cause the system to temporarily cut assistance, making it suddenly stiff.
· Failing Sensor or ECU: More consistently, the issue could be a failing torque sensor (which tells the ECU how much to assist) or a faulty ECU itself. These can fail intermittently before becoming permanent, or a "drifted" sensor may feed bad data to the ECU, causing unusual feel without triggering a warning light.

First step: Check your dashboard for a warning light (like an EPS or steering wheel icon). If it's on, the system is detecting a specific error.

If it happens again, note your speed and steering mode first. If it feels completely random, it's safest to have a mechanic inspect the system's wiring and connectors before a potential failure at speed.
