How to Solve the Stiffness of Electric Power Steering?

Tire toe-in value is incorrect, it is necessary to go to a 4S shop to adjust the tire toe-in value, and a four-wheel alignment may be required if necessary. The steering wheel components lack lubricating oil, applying lubricating oil to the components can solve the problem. The steering column is stuck, replacement of the steering column may be necessary in certain cases. The steering angle sensor is not sensitive, check if it is due to poor lubrication of the angle sensor, replacement is also an option.
I just encountered electric power steering stuttering, which is quite a common issue mostly caused by dirty sensors or software bugs. First, clean the sensor connectors: turn off the engine, unplug the connectors, and remove dust with a soft brush or compressed air, being careful not to get any moisture inside. If the stuttering improves, it might have been caused by dust interfering with the signal. Next, check the software: most cars have a self-diagnostic function—connect an OBD tool to check for error codes. If you find steering system errors, try resetting or updating the firmware using a mobile app or the manual for guidance. If that doesn’t help, test the battery voltage: low voltage can cause unstable motor operation—use a multimeter to check if it’s above 12V. If the problem persists, seek professional inspection: a repair shop can perform in-depth checks on sensors and motors for wear and tear. Replacing parts may cost money but ensures safety. Key maintenance tips: avoid prolonged aggressive steering wheel turns, and less dust buildup means fewer stuttering issues.
