According to Mr. Thai Binh Quoc Vu, owner of Anh Chu Xuong garage - Ninety eight Auto (Thu Duc City, Ho Chi Minh City), not all damages on cars are warned by the electronic system with indicator lights on the instrument panel.
In many cases, the car emitted unusual sounds that could help the driver recognize signs of degradation of mechanical details.
According to Mr. Vu, paying attention to listening to noises when starting up and during operation is a simple but effective way to detect errors early, thereby handling them promptly and limiting large repair costs.
One of the common signs is that the car vibrates more strongly than normal immediately after starting. If the engine compartment vibrates a lot, the body sounds loud or the person sitting in the car clearly feels the shaking compared to before, the cause may stem from the rubber foot of the engine that has become stiff, cracked or damaged.
This is the part that absorbs vibration from the engine before transmitting it to the car frame. When the engine leg rubber is degraded, the ability to reduce vibration is significantly reduced, causing the entire car body to vibrate more. Although the replacement cost is not low, this is a fairly long-lasting item and should prioritize the use of genuine parts to ensure durability as well as stable operation.
During the movement, if the car emits a "crushing" sound when passing through potholes or bumpy roads, users should quickly check the chassis or shock absorber system (shock absorbers) which are two core parts of the car's suspension system. These are large load-bearing components, so they are prone to aging after a long period of use.
Depending on the actual situation and each car line, the car owner may only need to replace or re-press the handlebars instead of replacing the entire handlebar cluster if the metal details are still guaranteed. Early detection will significantly reduce repair costs.
In addition, the brake system also often emits warning signals before serious damage occurs. If the brake pedal sounds, whistles, or feels abnormal feedback when braking, it is very likely that the brake pads are worn or the brake pin needs to be cleaned.
Continuing to use used brake pads not only reduces braking efficiency but can also cause brake disc damage, leading to higher repair costs and directly affecting traffic safety.
In addition, the whistling, howling, or "whistling" sounds that appear when accelerating should not be taken lightly. This may be a sign that the fuel system is operating unstablely or the exhaust system is open, cracked, dirty, or degraded.
If not handled early, the car may operate inefficiently, consume more fuel and generate more repair items.
Also according to Mr. Vu, people with many years of driving experience are often very sensitive to changes in the sound of the car. Forming a habit of listening to engine sounds, suspension systems, brakes and exhaust pipes during use will help detect abnormal signs early, maintain them at the right time, while limiting the risk of serious damage and extending the life of the car.
