5 "Silent" Habits That Prematurely Damage Your Car

Những hành động tưởng chừng vô hại hàng ngày này lại chính là "sát thủ thầm lặng" làm giảm tuổi thọ của xe mà bạn không hề hay biết.

1. Shifting Gears Before the Car Comes to a Complete Stop

This is one of the most common mistakes, especially when drivers need to park or make a U-turn. Shifting from reverse (R) to drive (D) or vice versa while the car is still moving creates a significant opposing force on the transmission.

This force not only causes an unpleasant noise but also wears down the gears and internal components, leading to rapid transmission failure and costly repairs. Always ensure the car has come to a complete stop before shifting gears.

2. Driving With a Near-Empty Fuel Tank

Many people have a habit of waiting for the low fuel warning light to turn on before refueling. However, this habit is very detrimental to the fuel pump system. The fuel pump's job is not only to push fuel but also to be cooled by that very fuel.

When the tank is nearly empty, the pump has to operate without sufficient cooling liquid, making it prone to overheating and premature failure. Furthermore, driving on an empty tank risks drawing sediment from the bottom of the tank into the system, causing blockages and damaging the fuel injectors.

3. Accelerating Hard Over Potholes and Speed Bumps

Driving over rough patches of road, such as potholes or speed bumps, at high speed is an action that causes severe damage to the car. The strong impacts can bend the wheel rims, damage the tires, break the shock absorbers, and even deform the chassis.

Driving carefully and slowing down when encountering poor terrain is the best way to protect the suspension system and other components underneath the car.

4. Constantly Dragging the Brakes While Driving Downhill

When driving downhill, many drivers have a habit of constantly dragging the brakes to control speed. This causes the braking system to overheat, rapidly wearing down the brake pads and potentially warping the brake rotors.

The consequence is that the brakes will shake when used, reducing braking efficiency and posing a danger. Instead, use engine braking (shifting to a lower gear) to slow down more safely and effectively.

5. Ignoring Warning Lights

The warning lights on the dashboard are not just decorative symbols. Each light carries an important meaning, alerting you to an issue occurring with the car. Taking these lights lightly or ignoring them, especially the engine warning light (check engine) or the oil pressure warning light, can turn a minor fault into a serious breakdown, causing engine damage and leading to enormous repair costs. Always pay attention and take your car for inspection immediately if any abnormal warning light appears.

Recognizing and changing incorrect driving habits is a simple yet incredibly effective way to protect your car. Small daily actions can help you extend your car's lifespan and save a large sum on repair costs.

If you are concerned about any abnormal signs from your "beloved car," visit the nearest CarOn-S center immediately for inspection and consultation by a professional technician team. Careful driving and periodic maintenance are the keys to keeping your car durable and in great condition.
