Electric power steering has become a popular and widely used technology in the automotive industry. However, like any other system, it is not immune to problems. In recent years, there have been numerous reports of electric power steering issues, ranging from minor steering wheel vibrations to sudden loss of steering control. These problems not only compromise the safety and performance of vehicles but also lead to expensive repairs and recalls by manufacturers. In this article, we will explore the common electric power steering problems, their causes, and potential solutions to help drivers better understand and address these issues.

Most Common Electric Power Steering Problems
Electric power steering (EPS) has become the preferred choice for steering systems in modern vehicles due to its efficiency and ease of use. However, like all systems, EPS can encounter problems that can affect its performance and safety. In this article, we will discuss the most common electric power steering problems and their potential causes.
1. Loss of Power Assist
One of the most common EPS problems is a sudden loss of power assist while driving. This can make steering difficult and cause the vehicle to pull to one side. The main culprit behind this issue is a faulty motor or a worn out power steering belt. The motor is responsible for providing assistance to the steering system, and if it fails, the system will lose power assist. In some cases, a loose or broken power steering belt can also cause loss of power assist.
2. Noise and Vibration
Another common EPS problem is the presence of noise and vibration when turning the steering wheel. This can be caused by a loose or worn out belt, a faulty motor, or a malfunctioning torque sensor. The torque sensor is responsible for ensuring that the correct amount of assistance is provided when turning the steering wheel. If it malfunctions, it can cause the system to vibrate or make strange noises.
3. Electronic Control Unit (ECU) Failure
The electronic control unit is the brain of the EPS system and controls all its functions. If the ECU fails, the EPS system will not function correctly. The ECU can fail due to various reasons, such as water damage, electrical surges, or manufacturing defects. A faulty ECU can cause the EPS warning light to illuminate on the dashboard and can also affect the vehicle’s stability and handling.
4. Wiring and Electrical Issues
The EPS system relies on a complex network of wires and sensors to function correctly. Any issue with the wiring can cause the system to malfunction. This could include loose or corroded connections, damaged wires, or faulty sensors. These issues can be challenging to diagnose and require a thorough inspection of the EPS system.
5. Faulty Steering Angle Sensor
The steering angle sensor is responsible for detecting the steering wheel’s position and providing this information to the EPS system. If the sensor is faulty, it can cause the EPS system to malfunction and result in stiffer steering or incorrect steering wheel alignment. The EPS warning light may also illuminate on the dashboard.
The EPS system is a complex and highly sophisticated system that generates a significant amount of heat while in operation. If the system does not have proper cooling, it can overheat and cause issues such as power assist failure, noise, and vibration. It is essential to regularly check and maintain the EPS system to prevent overheating.
In conclusion, electric power steering systems, like any other system, can encounter problems that can affect their performance and safety. Regular maintenance and timely repairs can help prevent these issues and ensure smooth and trouble-free steering. If you encounter any of the above problems with your EPS system, it is essential to have it inspected and repaired by a qualified mechanic to ensure the safety and reliability of your vehicle.
In conclusion, electric power steering (EPS) has revolutionized the way we steer our vehicles, providing a smoother and more efficient driving experience. However, as with any technology, EPS also has its fair share of problems. From electrical malfunctions to steering column failures, these issues can potentially compromise the safety and reliability of our vehicles. It is crucial for car owners to be aware of common EPS problems and take preventive measures to avoid potential hazards. Regular maintenance and proper handling of the vehicle can go a long way in avoiding EPS problems. In the rapidly evolving world of automotive technology, it is imperative for manufacturers to address these issues and continuously improve EPS systems to provide a safe and seamless driving experience for all.
