Can the weight of an electronic power steering wheel be adjusted?

Yes, the weight of an electronic power steering wheel can be adjusted. By adjusting the pressure of the hydraulic system, the weight of the hydraulic power assistance can be modified. Most vehicles have a pressure adjustment device near the outlet of the power steering pump. Hydraulic power steering wheels include both mechanical and electronic types. The differences between electric power steering and electro-hydraulic power steering: Electro-hydraulic power steering replaces the traditional hydraulic pump with an electric pump, which is controlled electronically; whereas electric power steering directly uses an electric motor to provide auxiliary torque, completely eliminating the hydraulic system. Electric power steering systems do not use power steering fluid and rely solely on the motor to provide steering torque, so there is no need to periodically replace the power steering fluid. Reasons for heavy steering: Insufficient tire pressure or changing tire models. Insufficient tire pressure increases the contact area between the tire and the ground, leading to greater lateral rotational friction, which makes steering heavier. The same principle applies when changing tire models. Steering gear failure. For example, water ingress causing jamming. The steering gear is located on the front axle, with dust covers on both sides, and there is also a dust cover where it connects to the steering column. If the dust cover is damaged or improperly sealed, moisture can enter the steering gear, causing rust and making steering heavier. For hydraulic power steering systems, dirty, insufficient, or air-contaminated power steering fluid can affect steering force. For electric power steering systems, the torque sensor may not be calibrated. Deformation of the front wheel suspension or abnormal wheel alignment (camber angle). Steering column jamming can also cause the steering wheel to feel heavy.
While driving my Hyundai, I discovered that the steering wheel weight can indeed be adjusted, which is quite a thoughtful feature. My car has an electric power steering system, making city driving effortless with its light steering—hardly any effort is needed for turns. However, when on highways or mountain roads, I switch to sport mode, where the steering becomes heavier, offering more stable control and significantly boosting driving confidence. Adjusting it is simple—just a quick setting change on the central control screen. I assume the principle involves the electronic system detecting driving mode changes and automatically adjusting the power assistance level, avoiding the overly stiff or floaty feel of older cars. Overall, this feature enhances daily driving flexibility and comfort, and I recommend new car owners explore their vehicle’s settings to make the most of this well-designed functionality.
