What are the reasons for the heavier electronic power steering wheel of the Sylphy Classic?

The reasons for the heavier electronic power steering wheel of the Sylphy Classic include: excessively tight fit between the rolling bearings and sliding bearings connected to the steering system, the pump pressure of the power steering pump failing to meet the standard value, low hydraulic pressure of the power steering gear, and the presence of air in the steering system. An excessively tight fit between the rolling bearings and sliding bearings connected to the steering system can reduce the lubrication effect of the bearings, causing sticking phenomena, which in turn results in a heavier steering wheel. Lubricating oil can be added. When the pump pressure of the power steering pump fails to meet the standard value, the steering wheel will feel heavy during use. Check the flow control valve. If there is leakage in the flow control valve or safety valve during driving, it can be repaired by grinding. Afterwards, check whether the spring of the safety valve has failed. The pump pressure can be adjusted at a 4S shop. When the hydraulic pressure of the power steering gear is low, the steering wheel will also feel heavy. If the steering wheel becomes heavier due to the oil pressure of the steering gear, it is necessary to go to a repair shop for maintenance in time. When there is air in the vehicle's steering system, not only will the steering feel heavy, but there will also be noise during the steering process. It needs to be addressed promptly to avoid unnecessary losses later.
I've been driving the Nissan Sylphy Classic for several years, and suddenly the steering wheel has become heavier, which is quite bothersome. Typically, the main culprit is an issue with the electric power steering system, such as wear and tear on the electric power steering motor or a malfunction in the control module, leading to insufficient power assistance. Additionally, low battery voltage or an underperforming alternator can be problematic, as the Sylphy Classic is an older model and the battery is prone to aging, affecting the power supply system. Insufficient tire pressure can also contribute to the issue, so it's worth checking if the tire pressure is below the standard value. Sensor failure or poor wiring connections are also common culprits, especially in high-humidity areas where corrosion is more likely. When the steering becomes heavier while driving, it's not just more strenuous but also increases the risk of accidents. Therefore, I recommend taking the car to a 4S shop for immediate inspection and repair, rather than waiting until a late-night highway emergency. Regular maintenance, including checking the battery and wiring, can prevent many of these issues.
As a car owner, I've encountered heavy steering issues with the Nissan Sylphy, mostly stemming from power steering system failure. Common causes include malfunctioning electric power steering motors or sensors, potentially due to loose wiring connections causing signal interruptions. Tire issues shouldn't be overlooked either - low tire pressure increases steering resistance, and a simple pressure check can rule this out. Aging alternators or batteries in the Sylphy Classic are also frequent culprits, as unstable voltage reduces power assistance. A secondary factor could be mechanical wear in the steering column components, but the power steering system remains the primary cause. When addressing this, don't rush into repairs - first check fuse and battery conditions, as these are low-cost inspections. Long-term neglect may create safety hazards, so timely professional servicing ensures driving safety. Early repair of steering problems brings peace of mind sooner.
