This is one of the most common EPS problems. When the power assistance is lost, steering becomes extremely difficult, especially at low speeds. This can be caused by a variety of issues, including a faulty electric motor, a blown fuse, a malfunctioning sensor, or a problem with the EPS control module.

Some EPS systems may exhibit intermittent problems, where the power assistance comes and goes. This can be caused by loose electrical connections, damaged wiring, or issues with sensors or the control module.

Excessive steering wheel vibration can be caused by problems with the EPS system. This could be due to issues with the electric motor or sensors that affect the system’s ability to provide smooth and consistent steering assistance.

Unusual noises while turning the steering wheel, such as whining or grinding sounds, can indicate problems with the EPS system. These noises can be due to issues with the electric motor, the power steering pump (if equipped), or the system’s mechanical components.

Many modern vehicles have onboard diagnostic systems that can detect EPS problems and trigger warning lights on the dashboard. A lit EPS warning light usually indicates a malfunction within the system, and it should be diagnosed promptly.

The EPS system relies on various sensors to determine steering angle, vehicle speed, and other factors. If one or more of these sensors fail or send incorrect signals, it can result in erratic steering behavior or a complete loss of power assistance.

Sometimes, EPS issues can be traced back to software glitches or calibration problems within the control module. Recalibrating the system or updating the software may resolve these issues.

Any issues with the vehicle’s electrical system, such as a weak battery or alternator problems, can indirectly affect the EPS system’s performance. Ensure that the vehicle’s electrical system is in good working order.

External factors like accidents or road debris can damage the EPS components, causing malfunctions or failures. Inspect the system for physical damage if you suspect an issue.

Occasionally, vehicle manufacturers issue recalls related to EPS systems due to safety concerns. It’s essential to check for any open recalls and have them addressed promptly.
