What Causes Heavy Steering Wheel in New Cars?

[Jones]

New cars may experience heavy steering due to insufficient power steering fluid, low tire pressure, or power steering pump failure. The specific causes and solutions are as follows: Insufficient Power Steering Fluid: Power steering fluid is a medium oil used in the car's power steering pump, which transmits steering force and provides cushioning. When the fluid is insufficient, the steering wheel may feel heavy and stiff. The solution is to regularly replace the power steering fluid. Low Tire Pressure: Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. The solution is to check the tire pressure. Power Steering Pump Failure: The steering gear and power steering pump are critical components affecting car steering. Any malfunction in these parts can cause steering difficulties. The solution is timely repair or replacement.
