What are the reasons for the heavy steering wheel of a new Buick Excelle?
1 Answers
New Buick Excelle steering wheel heavy reasons and solutions are as follows: 1. There is a problem with the power steering system. Buick Excelle commonly has two types of power steering systems: hydraulic steering and electric steering. For vehicles with hydraulic steering, it is necessary to check whether the power steering pump belt is normal, whether the power steering fluid level is normal, and whether there is any deterioration. If the power steering fluid is insufficient, it can be added. If the power steering fluid has deteriorated, the power steering fluid needs to be replaced. If there are no issues with these, the power steering pump may be faulty and needs to be replaced. For vehicles with electric steering, it is necessary to check whether the electric steering plug connection is normal and whether the power supply is normal. If there are no issues, the electric steering gear may be faulty. The steering system is actually quite complex, especially the electro-hydraulic power steering system, which incorporates many electronic sensors that can adjust the oil pressure of the power steering pump based on the vehicle speed, making it lighter and more stable at low speeds. Sensor malfunctions can cause the steering to become too heavy, and these issues require detection equipment for inspection and repair. 2. Severe deformation of chassis components leading to mechanical damage to the steering mechanism. In this case, the vehicle needs to be towed to a 4S shop or repair shop for inspection and repair. Insufficient tire pressure can make the driver feel that the steering wheel has become significantly heavier, and it can return to normal once the tire pressure is replenished to the standard level. If the car's steering wheel assistance becomes heavy, the steering system should be thoroughly inspected using instruments.
