What are the frequent breakdowns of cars

It is inevitable that there will be some failures during driving, so what are the more common failures?

1: The back door can't be opened

The backseat passenger wanted to get out of the car, but found that the door could not be opened, so he gently pulled the handle from outside the door and opened it. Newbies may think: Oh no, it looks like the door lock is broken.

Actually, it's just the child safety lock that works. In order to prevent children from accidentally opening the door from inside the car while riding, many vehicles are equipped with child locks, which can only open the rear door from the outside if this device is accidentally activated. In this case, just turn off the child lock.

Some cars have child locks on the side of the rear door, while others have the lock on the side of the rear door, which can only be adjusted when the door is opened.

2: The air conditioner is not cool enough

Some novices often envy the air conditioner in other people's cars so cool, and their own car turns on the air conditioner to the maximum, at most it just feels "not too hot", and every time the air conditioner is turned on in the sun, it takes a long time to cool down in the car. You're probably ignoring the role of the inner and outer loop buttons. If the vehicle activates the air circulation inside and outside the air conditioner, the cooling effect will be significantly reduced, but the advantage is that the air is relatively fresh.

On the contrary, if the internal circulation of the air conditioner is simply used, the cooling capacity will be greatly improved, but the disadvantage is that there is a lack of internal and external air exchange, and the air in the cabin is not fresh enough.

3: The steering wheel is stuck

When you start the car, you are surprised to find that the car key does not move, or the steering wheel is stuck, in this case, do not think that the car is broken, and ask someone to fix it, because it is just the steering wheel lock of the vehicle that works. The steering wheel automatically locks when parked, which is very common on sedans. A feature.

Although the steering wheel lock is primitive compared to most electronic immobilizers, it still has a good anti-theft effect for thieves because the steering wheel cannot be turned even if the car is successfully started.

4: The suspension feels too stiff

Obviously, I felt quite comfortable when I bought a car, why is the suspension so hard when I drive it now?And when I sit in someone else's car of the same style, I don't feel so bumpy. In this case, it is necessary to pay attention to check whether the tire pressure is too high.

When the tire pressure is appropriate, the tire can absorb the bumps from the road well, but if the tire pressure is not suitable, especially if the tire pressure is too high, the tire will lose the ability to absorb shock.

5: Fuel consumption is too high

There is another big problem that novices often have a headache for, and that is fuel consumption. Fuel consumption is the most important criterion that distinguishes novices from veterans. Novices not only do not know enough about the route, but also do not know enough about the temperament of the vehicle.

Driving a manual transmission car, often driving at low gear and high speed or high gear and low speed will have a great impact on the engine and fuel consumption. When driving an automatic transmission car, novices do not know how to use the depth of the throttle to control the gear, and it is reasonable that fuel consumption remains high.

It is inevitable that there will be this and that kind of problems when the car is driving on the road, so is there no way to avoid these problems? In fact, if you have some understanding of the car, we can still solve some small problems ourselves.

Low oil alarm light on:

Cause of failure: the red light of the oil pot is on, if it is not a sensor failure, it is generally the lack of engine oil, and continuing to drive in the absence of oil is likely to cause the piston to break the cylinder block, and the car will suddenly shut down, which is not only very dangerous, but also the next maintenance cost is also very high.

Parking inspection: 1. Some cars burn engine oil, and car owners should be very experienced and can add matching engine oil by themselves. In the open suburbs, there is no other vehicle to help, and you have to drive forward, and you can't buy engine oil nearby, you can temporarily go to some stalls to buy soybean oil or peanut oil temporarily, and you should change the oil immediately after driving to the repair shop, otherwise it will leave a lot of charcoal.

This is a last resort. If you have other vehicles, you can borrow oil from them.

2. If you accidentally bump into the fuel tank and cause oil leakage, and there is no maintenance location nearby, we can chew the gum and paste it on the oil leakage part of the fuel tank, because after the chewing gum dries, it can tightly block the dripping oil part, which plays a good role in emergency relief.

3. If the oil circuit is damaged due to impact, don't add engine oil and ask for road assistance.

Brake light alarm on:

Cause of failure: If we encounter the brake warning light on during the long distance, it means that the brake fluid level is not enough, and the brake system may be leaking.

Special reminder: at this time do not continue to drive, must be added in time to buy brake oil, if due to environmental factors can not buy brake fluid, you can buy a high number of liquor temporarily replaced, will not affect the effect of brakes, but can not brake frequently, should be immediately driven to the repair shop after the emergency maintenance.

Before traveling, it is necessary to check whether the braking system is normal, including: the degree of wear and tear of the brake pads, and also pay attention to whether the booster oil is sufficient. Special attention should be paid to the sub-cylinder dust jacket of the brake system, because if this component breaks into the dust, China's automobile industry is developing rapidly, and the industrial strength is constantly increasing.

With me, it will cause the piston to fail, which will lead to the increase of the braking distance when the car is braking; If water enters this part, brake failure will occur due to water mixed with the brake fluid. Therefore, whether the dust jacket enters water or dust, it must be comprehensively inspected and repaired to prevent the brake from failing for long-distance driving.

I hope the subject and netizens are grateful.

The common problems of automobiles are: 1. The engine cannot be started; 2. Puncture and puncture; 3. Brake failure; 4. Abnormal noise of the body and engine. Cars are often present.

The solution to the problem is: 1. Use a wire or emergency power supply to charge the battery; 2. Check and repair the circuit oil circuit; 3

Check the tire pressure and grind regularly.

damage; 4. Maintain the brake system; 5

Regularly check the consumption degree of brake discs and brake pads; 6. Try to avoid stepping on the brakes for a long time, and choose low gear when going downhill.

bit, to avoid overheating the brake pads; 7. Inspect and repair generators, water pumps, and steering power pumps.

The first: burn the oil. The phenomenon of burning engine oil is as follows: 1. Touch the exhaust pipe with your hands, find that there is a black and wet oil sludge accumulation, and smell the organic oil. 2. Blue smoke comes from the exhaust pipe of the car. 3. In the case of no oil leakage, the oil is seriously lacking.

There are two main reasons why cars burn engine oil. One is the common problem of the model, which is difficult to solve.

One is caused by excessive wear and aging of the internal components of the engine as the vehicle ages. This situation can be solved by simply replacing excessively worn and aging parts.

The second: vehicle jitter. There are many reasons for vehicle jitter. It is possible that there is a problem with the chassis, such as loose structures such as front and rear suspension, steering, and transmission.

It may be a problem with the tires, such as a large difference in tire pressure between the four tires; There is a problem with the dynamic balance of the tire, etc.

In addition, problems in any part of the ignition system, air intake system, and fuel system may cause the car to shake.

Solution: First determine that there is a problem with the car, and then repair it symptomatically.

The third: the fault light of the dashboard is on. For example, engine fault lights, tire pressure warning lights, oil warning lights, and so on. Depending on the model, the difference will be large. It is recommended to check the vehicle instruction manual, which will have a clear explanation.

Solution: Stop for inspection, if the situation is more serious, don't continue driving, contact a 4S shop or a professional auto repair shop as soon as possible, and ask for professional help.

Fourth: battery problems. For example, the battery is losing power, the battery life reaches the limit, and so on. There is a problem with the battery, the car can't catch fire, and there is a "squeak" sound when it is fired, and the car dashboard lights up the fault light.

The life of a battery is generally about four years, that is to say, it is necessary to consider replacing the battery in about four years. In addition, when locking the car at night, be sure to turn off the electrical facilities in the car, especially the headlights, if you forget to turn it off, the battery is easy to lose power the next day.

1. The engine cannot be started During the driving of the car, the engine is turned off and cannot be restarted.

2. The car cannot drive due to the failure of the drive train Under the condition of engine operation, the car cannot start and drive faulty.

3. After parking in summer, you can no longer start driving.

Hello dear. What exactly is the fault of the pro.

Ask the yellow one.

1. The main reasons why the engine cannot be started are: check whether the distributor, spark plug, high-voltage line, etc. are damp due to the rain or car washing. Check whether the battery voltage is sufficient;

Solution: Turn off the vehicle first, dry the parts of the damp part before starting the car; Temporary power supply is provided by connecting the connecting cable to the battery of another (torture) vehicle in order to start the vehicle.

2. The main reasons for the vehicle to turn off when changing gears are: the engine idle speed is too low; The idle shut-off valve is not tightened and the plug comes off.

Solution: Adjust the gear to the correct idle gear according to the vehicle situation; If the plug on the idle shut-off valve or connection section falls off, simply plug it back in.

3. The steering wheel trembles when the vehicle is moving, and the main reasons are: whether there are mud blocks, stones and other debris sticking to the tires of the vehicle; The tire is deformed by impact or the wheel balance weight falls off; Wheel alignment is not performed after the tire is replaced.

Solution: Remove stones from the gaps of the tires and debris stuck on the wheels. In order to avoid potential safety hazards, the deformed tires should be replaced in time, and the nearest auto repair shop should be found to install the balance weight. You should find a professional auto repair shop in time to carry out four-wheel alignment to avoid potential safety hazards.

Extended information: In addition, the refrigeration principle of air conditioning is to rapidly evaporate and absorb heat through the refrigerant, so that the temperature of the air flowing through it drops rapidly. Since the temperature of the evaporator is low and the air temperature is high, the water molecule particles in the air will condense into water droplets on the evaporator;

Dust in the air or small fluff on clothes and seats can easily adhere to the surface of the condenser, resulting in mold and bacteria. Therefore, the air conditioning system must regularly replace the air conditioning filter element, clean the air passage, and ensure the health of the car driver and passengers.

Personally, I understand that there are three types of faults that often occur in cars:

First, the common fault is related to the frequency of vehicle use, the frequency is too low, the battery voltage will be reduced, the battery can not be effectively charged, and secondly, the tire pressure will be reduced.

Second, it is a normal driving vehicle, the common problems are oil combustion failures, throttle carbon deposits, fuel injector carbon deposits, and three-way catalysis, which will lead to a decrease in vehicle power and even engine failure**.

Third, it is the high-frequency use of vehicles, the conventional faults brought by brakes, tires, and oil leakage, and suspension abnormal noise, of course, this is a conventional loss, but it can also be understood as a problem and failure that can occur.

Let's talk about a few common failures in our daily lives:

1. Gasoline lamp failure.

2. Engine fault lamp.

Engine fault light indicates that the engine inside or the circuit is faulty, if there is no other abnormality in the body, you can find the nearest auto repair shop for maintenance inspection, if accompanied by other abnormalities such as body shaking, lack of strength, etc., it is recommended to the insurance company to drag it to the maintenance point for maintenance. (Insurance companies generally buy insurance and send it to the same city as a towing service).

3. Airbag light.

When the airbag light is on, it means that the airbag sensor signal is faulty, and you can consider starting the maintenance point slowly for inspection and maintenance.

4. Water temperature alarm light.

When the water temperature warning light is on, it means that the engine temperature is too high, and the internal temperature cannot be dissipated, so you should immediately pull over and wait for the water temperature on the dashboard to express the normal indication before driving to the maintenance shop for maintenance.

5. Tire pressure indicator.

When the tire pressure indicator is on, you can observe whether the tire is dented, nailed, and exposed, and repair the tire at the selected maintenance point.

6. Oil lamp.

When the oil lamp is on, it means that there is an abnormality in the oil pressure inside the engine, and you can take out the oil scale to see if there is a suspicion of lack of oil.

That's all for me, and I hope it can be helpful to you.

It is inevitable that there will be some failures during driving, so what are the common failures?

1: The back door can't be opened

The passenger in the back seat wanted to get out of the car, but found that the door would not open. As a result, with a slight pull of the handle from outside, the door was opened. Newbies may be wondering:

Oh no, it looks like the door lock is broken. In fact, it's just that the child safety lock is easy to use. In order to prevent children from accidentally opening the door from inside the car while riding in the car, many vehicles are equipped with child locks.

If this unit activates unexpectedly, the rear door can only be opened from outside the car. In this case, simply close the sub-lock. Some cars have a child lock located on the rear door handle, while others have a lock on the side of the rear door and can only be adjusted when the door is opened.

2: Empty isn't cool enough.

Some novices often envy the cool air switch on other people's cars, while their own handlebar air switch is turned to the maximum, at best, it just feels "not too hot", and every time you turn on the air switch in the sun, it takes a long time to cool down in the car. You may have overlooked the function of the inner and outer loop buttons. If the vehicle starts the air circulation inside and outside the air, the cooling effect will be significantly reduced, but the advantage is that the air is relatively fresh.

On the contrary, if only the air-internal circulation is used, the refrigeration capacity will be greatly improved, but the disadvantage is the lack of air exchange between the inside and outside air, and the lack of fresh air in the cabin.

3: The steering wheel is stuck

When I started the vehicle, I was surprised to find that the car keys wouldn't turn or the steering wheel was stuck. In this case, don't think that the car is broken and get someone to fix it, because only the vehicle's steering wheel lock works. The steering wheel automatically locks when parked, which is a very common feature in cars.

Although the steering wheel lock is more primitive than most electronic immobilizers, for thieves, the steering wheel cannot be turned even if the car starts successfully, so it still has a good anti-theft effect.

4: The feeling of levitation is too hard.

Obviously, I felt quite comfortable when I bought the car. Why is it so hard to drive now? In addition, taking someone else's car of the same style does not feel so bumpy.

In this case, pay attention to check if the tire pressure is too high. In fact, tires are a very important shock absorber on a vehicle. When the tire pressure is right, the tire absorbs the bumps in the road surface well.

However, if the tire pressure is not suitable, especially if the tire pressure is too high, the tire will lose its shock absorption ability.

5: Fuel consumption is too high

Another big headache that novices often have is fuel consumption. Fuel consumption is the most important criterion to distinguish a novice from a veteran. Newbies don't know enough about the route and the temperament of the vehicle.

Cars with manual transmissions, often driving at low speeds or high speeds or low speeds, can have a big impact on engine and fuel consumption. When driving an automatic car, novices don't know how to use the depth of the throttle to control the gear, so it is reasonable to keep the fuel consumption high.

When driving on the road, it is inevitable that there will be problems of one kind or another, so there is no way to avoid them? In fact, if you know anything about cars, we can still solve some minor problems ourselves.
