● About abnormal sound

1. Abnormal sound near the steering wheel

Netizens "Speeding Lovers" and "Ah Lai Lei" all said that their car will make an abnormal sound in the position of the steering wheel in front of the steering wheel near the windshield.

The netizen "rides the cat to run the road" said that his Sonata 8 A-bar abnormal sound, left and right A-pillars, I would like to ask the experts how this is going on.

For the A-bar abnormal sound, the expert said that it is very likely that the A-pillar attachment sheet metal interference caused, the treatment method is still to go to the 4S shop for professional testing, the problem is not big.

3, skylights abnormal sound

The netizen "mb33243780" said that his name map skylight has abnormal noise, and he wants to consult an expert how to solve it.

Experts said that this problem has been dealt with before. The abnormal noise of the car is due to the fact that in the case of poor road conditions, the car body is twisted during the driving process, causing the skylight frame to interfere and causing abnormal noise. The solution is also very simple: stick the flannel strip at the skylight frame to prevent interference, and the problem can be solved smoothly.

In fact, no matter what kind of car or no matter what type of car, the abnormal sound is almost the most common problem in the process of using our car. Some abnormal sounds can be tolerated, but some abnormal sounds, such as the transmission of key parts such as the gearbox, have to be taken seriously. There may be many reasons for the abnormal noise. According to the expert's suggestion, the root cause of the abnormal sound must be determined first. What is the abnormal noise of the engine? Or is the body noise? Or is the tire noise too large? The safest method is to go to the manufacturer's designated repair and after-sales service center for system professional testing. Once the source of the noise is clear, targeted measures can be taken to eliminate the abnormal noise.

● About modification

For the modification, the most is the headlights of the car. Many netizens said that their car halogen headlights are not bright enough. As the netizen said, "How big is the rain," if you install a xenon lamp. So open and bright, and have a face, why not both?

However, the experts said that if the vehicle is modified, the related electrical equipment will not meet the requirements of the three guarantees, that is, it is not covered by the manufacturer's warranty. So the modification is risky, please be cautious!

In addition, experts also reminded that electrical equipment such as headlights are controlled by the body computer. If you install or install a xenon lamp in an unprofessional place, it will interfere with the body computer and may affect other functions of the body. The warranty of the vehicle also has an impact. It is recommended to go to a professional 4S shop for installation.

● About suspension

Netizen "Jun Lin Sheng Shi" said that his Sonata eight generations are currently driving 10,000 kilometers, the phenomenon of rear suspension sinking (commonly known as collapsed buttocks) is more serious, how to deal with experts?

In this issue of the expert online, we found that the phenomenon of "walking ass" is still quite a lot. In this regard, the experts also said that the manufacturer has a reference value for the suspension of the suspension after the empty state, which is 5-10mm. Therefore, if the 10,000-kilometer phenomenon of serious assocks appears, it is recommended to go to the 4S shop for inspection.

● Other issues

　　 The above are some of the problems that some netizens have concentrated on, and some of them are less frequently reflected, but Director Wang Hui also believes that it is a very representative issue. Xiaobian is here to organize the list for your reference.

1. How long is the cleaning mileage of the electronic throttle?

The cleaning range of the general electronic throttle is 1.5-2 million kilometers, which will be related to the fuel injection of the engine and the speed-up effect of the car.

2. What is the black ash on the inner wall of the exhaust pipe?

These black ash is the carbon deposit generated when the car is cold and the fuel is not fully combusted. It is normal.

3. How much is the oil storage capacity of the fuel tank?

Usually, the fuel quantity of the fuel tank should be kept at half of the fuel tank. If the fuel is too small, it will be detrimental to the heat dissipation of the oil pump and reduce the life of the oil pump.

4. After changing the oil of No. 92, why does the car become weaker and the fuel consumption becomes higher?

Due to the pursuit of better environmental protection, the No. 92 oil gasoline has reduced the sulfur content in the gasoline, resulting in a low octane number. Therefore, compared with the previous No. 93 gasoline, the power is weaker and the fuel consumption will increase accordingly.

● Summary

Judging from the questions of netizens, the problem of concentrated reaction is the abnormal noise problem. Of course, this can also be said to be a general problem of the whole car. In fact, the problem is not big, just go to the 4S shop to do professional testing, and you will soon find the source of interference and eliminate it. As for the phenomenon of "collapsed ass" that many netizens care about, experts also said that the springs will be weak when used for any model, and there will be some sinking, but this will not affect the safety of driving and the comfort of the car. In short, the maintenance and maintenance of the vehicle is a big problem. In the spirit of safety first, the owners should develop a good habit of paying attention to the condition of their car!
