Why is the steering wheel of the Q50L so heavy?
2 Answers
The reasons for the heavy steering wheel of the Q50L are as follows: 1. Insufficient power steering fluid: The power source for the car's movement comes from the power steering fluid, so if the fluid is insufficient, the car will have difficulty moving forward. 2. Contaminated power steering fluid: If the vehicle's power steering fluid is mixed with unclean gases or impurities, the fluid cannot function properly, leading to difficulty in turning the steering wheel. 3. Issues with the power steering system: The steering wheel is closely related to the power steering system. If there is poor electrical contact or other problems within the system, the steering wheel will become heavy. 4. Low tire pressure: When the car's tire pressure is too low, the steering wheel will become heavier, and it may even lead to a tire blowout. Therefore, if you feel the steering wheel becoming heavy, check the car's tire pressure and the power steering fluid.
I've been driving the Infiniti Q50L for about two years, and the steering wheel is indeed noticeably heavier than other cars. Initially, it required more effort when parking or turning at low speeds. This is mainly due to the design preference of the car's power steering system; Infiniti aims for a sporty feel by tuning the electric power steering to be stiffer, which enhances stability at high speeds. Tire pressure is another factor—if the tires are underinflated, even dropping from 30 psi to the low 20s can increase resistance, making the steering feel heavier. Additionally, issues with the steering system itself, such as a faulty power steering pump or aging sensors, can exacerbate the sensation. Regular maintenance and proper tire inflation can help alleviate this. Over time, I've grown accustomed to it and actually find it quite comfortable—the car feels more dynamic and offers precise handling.
