6 most "misbehaving" parts of a car

1. Vehicle lighting system

The lighting system has the function of emitting signals and warnings to help us avoid unfortunate collisions. However, after a period of use, the lighting system will often break down quickly, and often break down unexpectedly.

The reason the light "misbehaves" and does not light up is because it is often shaken by strong shocks due to road conditions with many "potholes", collisions, unstable power sources, or the battery voltage exceeds the voltage limit of the bulb.

The way to prolong the life of the car's lighting system is to avoid driving on bad roads that cause the car to jolt. In addition, it is necessary to check the car's lighting system every 6 months on average to ensure safety and avoid unexpected incidents.

2. Engine air filter

The role of the engine air filter is to completely filter out dirt in the air entering the engine. Therefore, this part is easily contaminated with dirt and reduces the filtering efficiency, causing insufficient air flow into the engine, causing fuel consumption, increased pollution levels and unstable engine operation.

You should check the air filter system on average once a year or after the car has rolled 20,000 km. However, if the car is driven in dusty areas, car owners should check this part more often so that the engine always has enough air to burn fuel best.

3. Brakes

It can be said that car brakes are one of the most important parts of a car to ensure safety because just a small problem can lead to traffic accidents that can cause many serious consequences.

The cause of brake failure is due to worn brake pads, inertness, lack of brake fluid, leaking brake oil pipes, etc. Because of the importance of this part, we must maintain the brake system every 20,000 km. Especially, before long trips or steep mountain passes, it is necessary to check and maintain the brakes carefully.

4. Fuel supply line

The fuel line from the tank to the injector is divided into several sections made of different materials; the section running along the chassis is made of metal, the section in the engine compartment is made of synthetic plastic and this is the sensitive section.

During use, this plastic pipe can be bitten by rats, the joints can shrink and open, causing leaks, even large leaks.

Immediately upon detecting an unusual smell of gasoline (some high-end cars may display an engine fault light when the pipe has a large puncture), an inspection is required. Fuel leaks are one of the conditions that pose a risk of vehicle fire when exposed to an electrical spark.

5. Wiper system

The wiper system ensures the driver has clear vision by wiping water from the front and rear windows when it rains; dirt can be cleaned from the front windshield by the washer fluid.

Normally, the wiper blade is the part that is most often damaged in the wiper system due to its rubber structure, which is subject to friction and environmental impacts most often. Experts recommend that we should replace the wiper blade after 12 - 18 months. However, in hot, humid and rainy weather conditions, the aging of the rubber blade will occur faster.

6. Oxygen sensor

The oxygen sensor (exhaust sensor) provides information to the engine control system about the concentration of exhaust gas, so that the fuel pump control system will provide the appropriate amount of fuel for the most efficient combustion, helping the vehicle achieve the best operating performance and save the most fuel, reducing environmental pollution.

Poor fuel quality (dirty fuel, mixed with many impurities, not up to standards) is one of the reasons why the exhaust sensor is damaged. At that time, the engine fault light will turn on, along with the fuel consumption may increase dramatically (up to 30%). Users need to bring the car to a trusted garage for inspection and treatment.
