Reasons Why the Steering Wheel Suddenly Becomes Hard to Turn

When the steering pump leaks oil or the power steering pump is damaged, the steering wheel may become hard to turn. Here are the detailed explanations: Steering pump oil leakage: This occurs in the steering system when air is not completely expelled after oil leakage. If the steering pump operates for a long time without sufficient oil, it can lead to severe wear, reducing the performance of the steering system. Repairing a leaking steering pump can be done by replacing the sealing rings and oil seals, or replacing the entire assembly if necessary. Power steering pump damage: Cars equipped with vacuum power steering should not experience difficulty in turning after the engine starts unless the power steering pump is damaged. For systems using electronic power steering, repeatedly turning the steering wheel while stationary or at low speeds places a heavy load on the system, which can cause the steering gear to overheat and become saturated, resulting in heavy steering.

This steering wheel suddenly became as hard as a rock, impossible to turn, which really gave us a scare. I remember once when I was driving that old buddy of mine on a road trip, as soon as I hit the highway, I felt something was off with the steering—it was unusually heavy, almost causing understeer and a collision with the guardrail. Generally speaking, this is a problem with the power steering system, possibly due to low hydraulic power steering fluid or a failing oil pump, leading to insufficient pressure. For cars with electronic power steering, it could also be caused by a weak battery or a faulty sensor, making the motor stop working. Such issues are more common in winter—I've even encountered the strange phenomenon of power steering fluid freezing in cold weather. Another risk is the steering column getting stuck or the belt breaking. If this happens while driving, immediately turn on the hazard lights and pull over—don't force the steering, or you might lose control. Since then, I've made it a habit to check the power steering fluid level every month, and during car maintenance, I always ask the technician to pay extra attention to the steering system to avoid surprises on long trips.

How to Turn On the Avalon Vehicle Stability Control System?

The Avalon vehicle stability control system is enabled by default and does not require manual activation. Below is relevant information: 1. The Avalon vehicle stability control system is enabled by default and does not require manual activation. If you need to disable it, press the ESP switch in the left control area of the center console to turn it off. Pressing the button again will re-enable it. After manual deactivation, the ESP off indicator will appear on the instrument panel. If the vehicle is restarted, the ESP system will be enabled by default. 2. The ESP operation is managed by the ECU, and no additional actions are required from the driver. Its purpose is to maintain vehicle stability in emergency situations. In scenarios where side skidding or fishtailing might occur, it balances power distribution across various mechanisms. By utilizing the principle of single-wheel power distribution, it effectively prevents accidents. During normal driving, this system should not be turned off arbitrarily. 3. Currently, automotive safety systems are divided into two categories: active safety systems and passive safety systems. Active safety systems refer to systems where the vehicle actively avoids accidents through the operation of various sensors, such as ABS anti-lock braking systems, brake force distribution systems, ESP vehicle stability control systems, and lane departure warnings. Passive safety systems, on the other hand, protect occupants or pedestrians during an accident, such as seat belts, airbags, and pedestrian protection devices.

What engine does the RX8 use?

The engine of the Roewe RX8 is manufactured in China and assembled at SAIC's Lingang production base, with technology provided by SAIC. The engine model of the Roewe RX8 is 20L4E, with a maximum horsepower of 222Ps, a maximum power of 163KW, and a peak torque of 360Nm. For daily maintenance of the Roewe RX8 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, choose SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, select CB--CD grade diesel engine oil based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it may burst the filter element or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
