What are the causes of electronic power steering failure in the Borui?

[MacHadley]

The causes of electronic power steering failure in the Borui are heavy steering or steering system oil leakage. Causes of heavy steering failure: The power steering system contains a small amount of air, causing abnormal car steering. Foreign objects in the steering hydraulic pipeline cause the steering pump flow control valve to stick. Loose connections in the power steering system lead to steering fluid leakage. Wear in the steering gear piston cylinder, poor sealing of oil seals, and sticking or damage of the control valve. Causes of steering system oil leakage failure: Clogged filter element, oil lines blocked due to rubber's poor resistance to oil corrosion, leaks at pipeline connection points, and air ingress. Worn pump components with excessive clearance lead to significant leakage. The pump outlet has no pressure. The oil does not meet specifications, with excessive viscosity causing high sliding resistance of the vanes, and the oil level in the reservoir is too low.

As an experienced driver who frequently repairs cars, I've encountered quite a few electronic power steering failures, especially in models like the Borui. There are many reasons for electronic power steering failure, with the most common being electrical circuit issues, such as blown fuses or aging fuse boxes. The electronic power steering system relies on an electric motor to function, and if the motor itself is worn or damaged—like from prolonged use on bumpy roads—it may stop working. Then there are sensor failures; problems with the torque sensor or angle sensor at the base of the steering wheel can cause the system to misjudge or provide abnormal feedback. Another common cause is control module abnormalities, such as software bugs or hardware damage, which may occur after a system upgrade. I recommend first checking the fuse, which is usually located in the fuse box under the steering wheel. If that’s fine, inspect the power cable connections for looseness or corrosion. Electronic power steering failure affects steering flexibility and can be particularly dangerous at high speeds, so timely repairs are essential—otherwise, the steering wheel may stiffen, making control difficult. The best approach is to have a professional shop scan for fault codes using diagnostic tools.

I've been driving the Borui for a while and encountered sudden loss of power steering last year, which was a real headache. Through research, I found the causes can vary: it might be a blown fuse in the power steering system, which easily leads to complete function failure—you can start by checking the corresponding numbered fuse in the fuse box. Another common issue is failure of the power steering motor itself, such as burnt motor coils or internal gear jamming, making the steering wheel extremely heavy. Sensor problems, like malfunctioning steering angle sensors or vehicle speed sensors, can also cause the system to shut down if it doesn't receive correct data. Poor wiring connections, aging or loose plugs, or environmental moisture causing short circuits are other potential factors. I later realized that aftermarket electronic devices like navigation systems could interfere with the system. When troubleshooting, don't rush to DIY—first confirm diagnostic prompts, and if the issue persists, seek professional repair immediately to avoid significant driving risks.

As an ordinary car owner, I've researched the power steering issues with the Borui, which mainly involve several types of failures: blown fuses are the most common, where a small component melting can shut down the entire system. If the power steering motor is worn or overheats, it may fail, and neglecting regular maintenance like lubrication makes this more likely. Sensor failures, such as a malfunctioning torque detector, are another major cause, potentially preventing the steering wheel from auto-correcting. Wiring aging and short circuits are equally dangerous, especially for wires in the chassis area that suffer from moisture corrosion. I believe that if you notice the steering becoming unusually heavy, you should immediately stop to check the basic components to avoid letting it escalate into a safety issue.

I often help beginners answer questions on forums. The electronic power steering failures in the Borui mostly stem from these points: blown fuses should be ruled out first; damage to the power motor is common after frequent use; sensor failures like signal inaccuracies can cause miscontrol; unstable circuit connections such as loose plugs are simple but easily overlooked. It's recommended to routinely check the fuse condition. If there are abnormal sounds or heavy steering, early inspection can prevent hazards.

I understand car maintenance. The causes of power steering failure include blown fuses, motor malfunction, sensor failure, wiring issues such as damage or moisture, etc. On the Borui, abnormal system control modules may also trigger fault codes. Pay attention to steering feel during daily driving, and send for repair promptly when changes occur to ensure safety.
