What Causes a Car to Suddenly Shake While Driving?
2 Answers
Regarding the situation where a car suddenly shakes while driving. Reason 1: When starting the car, avoid abrupt acceleration. Whether the car is empty or loaded, start smoothly at a low speed. This prevents the tires from dragging on the ground, reducing tread wear. Reason 2: On good road conditions, maintain a straight path. Avoid unnecessary swerving or sharp turns, except when passing other vehicles or avoiding obstacles. This prevents lateral cutting damage between the tires and rims. Reason 3: When driving downhill on a long slope, control the speed appropriately based on the slope's gradient, length, and road conditions. For steep, long, or complex terrains, engage a lower gear and use gentle braking to control the speed. This not only avoids emergency braking and reduces tire wear but also ensures safer driving.
I've encountered sudden vehicle shaking multiple times while driving, which is usually related to the ignition system. The most common cause is aged or faulty spark plugs, leading to uneven engine ignition and causing the car body to sway. If there's an issue with the ignition coil, the situation worsens, especially noticeable during acceleration. Uneven tire pressure or imbalanced tires is another significant factor, particularly prominent when driving on highways. Additionally, poor fuel supply, such as clogged fuel injectors or a dirty fuel filter, can affect combustion efficiency and cause shaking. A severely dirty air filter restricting air intake can also lead to the same problem. Once shaking occurs, I recommend slowing down and pulling over to check, avoiding curves or congested areas. Regular maintenance of these components can effectively prevent such issues.
