## Common causes

The Electric Power Steering (EPS) system in your 2017 Chevrolet Equinox is complex, and several components can lead to a 'power steering assist reduced' warning:

*   **Electric Power Steering (EPS) Motor Failure:** This is arguably the most frequent culprit. The electric motor, responsible for providing the steering assist, can fail internally due to wear, electrical shorts, or overheating. When this motor malfunctions, the system cannot provide the necessary assist.
*   **EPS Control Module Failure:** The control module (often integrated with the EPS motor or steering gear assembly) manages the motor's operation based on sensor inputs. A fault in this module can lead to incorrect or no assist. This is a critical component of the Chevrolet Equinox's steering system. For more information on your specific model, visit our [Equinox model hub](/vehicles/chevrolet/equinox).
*   **Steering Torque Sensor Issues:** This sensor detects how much force the driver is applying to the steering wheel. If it malfunctions, the EPS module won't know how much assist to provide, leading to either too much or too little assistance.
*   **Wiring Harness or Connector Problems:** Damaged, corroded, or loose wiring and connectors within the EPS system can interrupt communication or power supply, causing the system to fail. This is often overlooked but can be a relatively simple fix if identified.
*   **Battery or Alternator Problems:** As EPS systems are entirely electric, they are highly sensitive to voltage fluctuations. A weak battery, a failing alternator, or poor grounding can starve the EPS module of consistent power, leading to reduced assist or complete failure.
*   **Software Glitches:** In some instances, a software bug or corruption within the EPS module's programming can cause intermittent issues. A reflash or software update from a dealership can sometimes resolve these problems.
*   **Mechanical Binding in Steering Gear:** While less common, internal mechanical issues within the steering gear itself (e.g., worn bearings, damaged gears) can create resistance that the EPS motor cannot overcome, mimicking an assist failure.
