What are some common car glitches that you know?

1.The car is performing abnormally.

The abnormal performance of the car is the poor power and economy of the car, which is mainly manifested in the obvious low maximum driving speed of the car and the poor acceleration performance of the car; Cars have a large fuel consumption and a large oil consumption. The ride comfort of the car is poor, and the vibration and noise of the car are significantly increased. The car has poor handling stability, the car is easy to deviate, and the front of the car oscillates; Brake mistracking, long braking distance or no braking, etc.

2.The working condition of the car is abnormal.

Some abnormal phenomena suddenly appear in the use of the car, which should be prevented: the engine suddenly stalls while driving; The car has no brakes when braking is required; The car can't start in winter; The engine does not start after it is turned off; Sudden failure of steering while driving; What's more, car tire bursts and car spontaneous combustion**. The symptoms are more obvious, and the causes are more complex, mainly because there is a fault in the interior of the car that is not noticed, and it develops into sudden damage.

3.The car is unusually loud.

In the use of automobiles, when a failure occurs, it is often most likely to manifest itself in the form of abnormal noise. Under normal circumstances, both the driver and the passenger can hear it. Experienced people can judge the car fault according to the different frequencies and timbre of the abnormal noise and the sound, the general sound is dull and accompanied by a strong vibration when the fault is more serious, should stop, reduce the engine speed or turn off the engine to find, some sounds are faulty in some parts, do not affect the use of the car, can not be found out for a while, you can drive the car back to the base or drive into the nearest car maintenance department to ask experienced personnel to find.

<> "In this situation, have you ever encountered a high level of ignition?

The seat belt won't pull out when you get into the car.

Sometimes the windows can't be raised, and they can't be lowered.

The steering wheel suddenly locks ......

These glitches are minor, but they have a special impact on the user experience.

So in the end, do you want to go to the 4S shop for repairs.

Shu Xiao, these situations can be solved by yourself!

Problem: When the vehicle presses the clutch pedal, it makes a "squeak" sound.

Solution: This phenomenon is caused by slight wear and tear of the clutch pedal support shaft due to long-term use, which can be alleviated by applying some lubricant to the support shaft position.

02.Problem: The auto hold function is sometimes good and bad, and sometimes it doesn't start.

Response: To meet the conditions of automatic parking power to start is to close the door and fasten the seat belt, when you find that the automatic parking function of your car is "out of order", you need to check whether the seat belt is fastened, whether the door is closed.

03.Problem: There is a "rattling" sound when braking suddenly.

Response: The "rattling" sound is the sound made by the ABS pump during the decompression work, and it will also be accompanied by the feeling of the brake pedal springing foot. This is to ensure that the wheels have both braking power and do not lock up.

04.Problem: Inconsistent lift and lift speed when closing or opening windows.

Response: This is due to the entry of sand and dust into the glass lifting track, which increases the friction resistance between the glass and the groove, and then produces this "false failure". The glass lifting track needs to be cleaned in a timely manner.

All of the above are car owners in driving.

Frequently encountered "failures that are not failures".

Please think about whether this is the case.

There are also common "little bugs" when driving

1. Improper adjustment of the stroke of the starting switch or electromagnetic switch; 2. Improper adjustment of the gap between the armature movable fixed contact and the movable contact; 3. The starter drive pinion or flywheel tooth is worn out or even slipped; 4. The fixing bolt of the starter is loose or the clutch housing is loose; 5. Internal failure of the starter. The reasons for the failure of the starter idling are: 1. The fork of the mechanically forced starter is out of groove, and the driving pinion cannot be pushed, or its stroke is improperly adjusted and cannot enter the mesh; 2. The core stroke of the electromagnetic switch of the electromagnetic control starter is too short; 3. The auxiliary coil of the armature mobile starter is short-circuited or broken, and the armature cannot be brought to the working position; 4. The starter is slipping in the one-way mesh.

The reasons for the failure of the starter are as follows: 1. The battery is insufficient or the connecting wire is loose and the contact is poor; 2. Ablation of the contact of the starting switch or short circuit of the electromagnetic switch coil.

If you encounter a car problem, you can go to repair or inspect, but if the manufacturer and the 4S shop cannot solve your problem, you need to complain through the official channel to protect your legitimate rights and interests.

The more effective way to complain:

Take car complaints as an example: 1. Complain to the car manufacturer, and call the corresponding customer service**. If the car has quality problems, it should be repaired at a 4S shop authorized by the manufacturer. If there is a problem, the 4S store does not accept it, and then contact the manufacturer;

2 You can also make complaints and feedback problems through third-party channels such as the China Complaint Platform. Through supervision, mediation and reporting, complaints can be solved or mediated efficiently, but the final handling situation should be based on the manufacturer to provide solutions, and the specific services after the 4S store can solve the problem.

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 battery of the other (torture) vehicle with the Buggy Connecting Cable 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 in 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.

<> "Let's talk about the common faults of cars.

To get straight to the point, the common faults of cars are:

1.Engine failure: including gasoline pump failure, ignition coil failure, cylinder head failure, etc.

2.Battery failure: Bao Song includes insufficient battery charging, battery damage, vehicle circuit failure, etc.

3.Cooling system failure: including pump failure, water tank failure, radiator failure, etc.

4.Transmission failure: including transmission oil temperature is too high, transmission stuck, transmission leakage bridge oil, etc.

5.Brake system failure: including brake pad wear, brake fluid leakage, brake pedal failure, etc.

6.Tire failure: including tire puncture, tire tread depth is too shallow, tire pressure is insufficient, etc.

There are many reasons for the common breakdowns of cars mentioned above, so I won't list them all here. However, in general, the causes of car breakdowns can be summarized into the following categories:

1.Breakdowns caused by improper use and maintenance of the vehicle, such as the use of inferior gasoline, oil quality imbalance, malfunctions caused by improper maintenance, etc.

2.Failures caused by the quality of the vehicle itself, such as unqualified vehicle parts, production process problems, etc.

3.Faults caused by external environmental factors, such as poor road conditions, extreme weather, etc.

4.Breakdowns due to unexpected causes, such as a vehicle being involved in a road accident, a vehicle being stolen, or being hit.

5.Failures caused by the use of the vehicle for a long time, such as serious wear and tear of vehicle parts, failure to replace worn parts in time, etc.

The hazards of car breakdown are many, the main ones are as follows:

1.Safety hazards: Car breakdowns can lead to loss of control of the vehicle and a car accident, resulting in serious personal and property damage.

2.Economic hazards: Car breakdowns require more economic costs to repair, and if the breakdown is severe, it can even lead to scrapping of the vehicle.

3.Affect use: Car breakdowns can cause vehicles to be unusable and affect people's travel plans.

In general, the causes of car breakdowns are very complex, which may be caused by improper use and maintenance of the vehicle, or by the quality of the vehicle itself, or even by external environmental factors or unexpected reasons, or even due to the long use of the vehicle. So, if the car breaks down, you should go to an auto repair shop for repair as soon as possible to avoid more serious consequences.

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.

The car sometimes emits black smoke, flashes sparks, abnormal sounds, heat, etc., when these conditions occur, it means that there is a problem with the circuit of the car, and these faults can be directly observed and judged directly.

1. Abnormal exhaust gas.

2. The distance of braking becomes longer.

3. The steering wheel is crooked.

4. The steering wheel is shaking.

5. Abnormal tire noise.

6. The temperature of the transmission is high.

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.

Second, the solution to these kinds of failures.

1. The engine cannot be started During the driving of the car, the fault that the engine is turned off and cannot be restarted should be checked according to the principle of first circuit and then oil circuit. Generally from the point of view of the failure probability of the two mechanisms and five systems of the engine, the failure rate of the electrical ignition system is the highest, accounting for 47 of the total number of failures, the oil supply system accounts for 18, and the others are secondary.

2. The fault of the drive train causes the car to not drive Under the condition of the engine, the principle of the inspection of the fault of the car cannot start driving is: the transmission is used as the boundary for sectional inspection.

3. This fault is mainly produced in the final reducer, it is very hot to touch the main reducer by hand, when the back cover is removed, there is no gear oil in the shell, the gear and other parts have been burned to purple blue due to high temperature, the planetary gear and the cross journal are sintered together and cannot rotate, the rolling resistance of the two rear wheels of the car is inconsistent, and the differential can not distribute the torque equally, so the car can not start driving.

Common car Bo Meng minor faults: 1. The engine cannot be started. If the battery is out of power, you can use the wire or emergency power supply for ignition, if it still can't start, it may be a vehicle circuit or oil circuit failure, it is recommended to send it to the factory for repair.

2. Puncture, puncture and other failures. The spare tire should be replaced in time, and if possible, the tire should be repaired in time.

3. The engine is turned off while driving. When the engine is turned off, it is easy to cause dangerous failures, and after the engine is turned off, the steering wheel and brake power will disappear, and the vehicle is easy to lose control. If the engine is turned off while driving, first stabilize the steering wheel, slowly apply the brakes, and park the vehicle on the base section of the bridge to the side of the road.

Excessive carbon deposits, oil circuit blockage, battery failure, water tank, engine belt and other components may cause the engine to stall, if the cause of the failure can not be determined, it is recommended to send it to the factory for repair.

4. The brake burns the car and fails. Do adequate maintenance of the brake system, often check the consumption degree of brake discs, brake pads and other components, and replace them in time if necessary. In daily driving, try to avoid applying the brakes for a long time, and in case of long downhill sections, it is recommended to cooperate with low gear and use engine braking to avoid overheating of brake pads.
