First: Abnormal noise during cold start

一個(gè)被官方承認(rèn)的原因：凸輪軸調(diào)節(jié)器存在設(shè)計(jì)缺陷，在質(zhì)保期內(nèi)損壞免費(fèi)更換，但是如果超過了質(zhì)保期則需要車主自掏腰包，而且更換費(fèi)用不菲。

One officially recognized reason is that the camshaft adjuster has a design defect and is damaged during the warranty period for free replacement. However, if it exceeds the warranty period, the owner will need to pay for it at their own expense, and the replacement cost is expensive.

第二：燃油泵存在隱患

Secondly, there are hidden dangers in the fuel pump

這也是得到奔馳認(rèn)可的一個(gè)通病，而且今年也為此召回了數(shù)十萬臺E級、C級等車型。在高溫天氣下容易引發(fā)車輛自燃，所以各位車主一定要認(rèn)真對待。

This is also a common problem recognized by Mercedes Benz, and hundreds of thousands of E-Class, C-Class and other models have been recalled this year. In hot weather, it is easy to cause vehicle spontaneous combustion, so all car owners must take it seriously.

第三：四輪定位容易失準(zhǔn)

Third: Four wheel alignment is prone to misalignment

這也是奔馳汽車普遍存在的一個(gè)問題，涉及到了旗下的多款車型，雖然這是所有汽車終會出現(xiàn)的問題，但是奔馳汽車四輪定位失準(zhǔn)的頻率較高，間隔時(shí)間較短，如果您發(fā)現(xiàn)自己的方向盤變得沉重不好回正，輪胎出現(xiàn)偏磨現(xiàn)象，那就是這個(gè)問題啦，除了重新進(jìn)行四輪定位之外，可能還需要更換懸掛膠套。

This is also a common problem in Mercedes Benz cars, involving multiple models under its umbrella. Although this is a common problem for all cars, the frequency of four-wheel alignment misalignment in Mercedes Benz cars is relatively high, and the interval time is short. If you find that your steering wheel becomes heavy and difficult to return to normal, and the tires show eccentric wear, then this is the problem. In addition to re aligning the four wheels, you may also need to replace the suspension rubber sleeve.

第四：噴油器臟污

Fourth: Dirty fuel injector

一到冬天就能經(jīng)常看到冒黑煙的奔馳汽車，很多不太懂行的車友會以為是燒機(jī)油，其實(shí)關(guān)鍵原因是奔馳的噴油嘴很容易出現(xiàn)臟污的現(xiàn)象，同時(shí)會引發(fā)啟動障礙、怠速發(fā)抖、動力下降甚至發(fā)動機(jī)無法啟動的問題，同時(shí)會加速積碳生成，這一點(diǎn)很多奔馳車主也在網(wǎng)上探討過，其實(shí)定期進(jìn)行清洗或者使用燃油添加劑就能解決。

In winter, Mercedes Benz cars that emit black smoke can often be seen. Many inexperienced car enthusiasts may think that they are burning engine oil, but the key reason is that Mercedes Benz's fuel injection nozzle is prone to dirt, which can cause starting difficulties, idle shaking, power loss, and even engine failure to start. At the same time, it can accelerate the generation of carbon deposits, which many Mercedes Benz car owners have also discussed online, In fact, regular cleaning or the use of fuel additives can solve the problem.

第五：轉(zhuǎn)向機(jī)漏油

Fifth: Steering gear oil leakage

這也是奔馳汽車一個(gè)比較常見的通病，因?yàn)楸Ｓ辛康年P(guān)系，普遍出現(xiàn)在國產(chǎn)的各款奔馳汽車上，老款的奔馳S級也容易出現(xiàn)這個(gè)問題，漏油后會出現(xiàn)打方向沉和異響現(xiàn)象，這時(shí)候除了要補(bǔ)充助力油之外，還需要更換油封。

This is also a common problem in Mercedes Benz cars, as it generally occurs in various domestic Mercedes Benz cars due to the ownership. The older Mercedes Benz S-Class is also prone to this problem, and after oil leakage, there will be directional sinking and abnormal noise. At this time, in addition to supplementing the booster oil, the oil seal also needs to be replaced.

第六：減震器斷裂

Sixth: Shock absorber fracture

這件事兒已經(jīng)出現(xiàn)了三年左右，普遍出現(xiàn)在國產(chǎn)E級、C級、GLA、GLC等車型上，故障原因就是奔馳前減震器插頭有設(shè)計(jì)缺陷，拖了兩年之后，現(xiàn)在奔馳也已經(jīng)做了召回處理，但是處理的方案并沒有完全公布，希望奔馳不要學(xué)當(dāng)年的大眾汽車，僅僅是打上一塊補(bǔ)丁敷衍了事，因?yàn)檫@直接危及到了車主的生命安全。

This incident has been happening for about three years, commonly on domestic E-Class, C-Class, GLA, GLC and other models. The cause of the malfunction is a design defect in the front shock absorber plug of Mercedes Benz. After two years of delay, Mercedes Benz has also carried out a recall, but the solution has not been fully announced. We hope that Mercedes Benz will not imitate Volkswagen back then and only apply a patch to perfunctory work, Because this directly endangers the safety of car owners.

第七：水泵損壞滲漏冷卻液

Seventh: Damaged water pump leaks coolant

這個(gè)故障普遍出現(xiàn)在老款的奔馳汽車上，但是至今也困擾著不少的奔馳車主，并且會因此引發(fā)節(jié)溫器故障，在冬天屬于高發(fā)時(shí)期，普遍出現(xiàn)在車齡四年左右，或者行駛里程七萬公里的奔馳車上，癥狀是一開暖風(fēng)、除霧風(fēng)功能后，發(fā)動機(jī)溫度就會調(diào)到60度左右，這會直接影響到發(fā)動機(jī)的使用壽命。

This fault commonly occurs in older Mercedes Benz cars, but it still troubles many Mercedes Benz owners and can cause thermostat failure. In winter, it is a high incidence period, commonly seen in Mercedes Benz cars that are about four years old or have a mileage of 70000 kilometers. The symptom is that once the heating and defogging functions are turned on, the engine temperature will be adjusted to around 60 degrees, which will directly affect the service life of the engine.

第八：火花塞壽命短

Eighth: Short spark plug life

奔馳汽車的火花塞壽命短，這也是一個(gè)普遍性的問題，會導(dǎo)致車輛的動力下降、加速時(shí)車身抖動、排氣聲變化、怠速抖動等現(xiàn)象，作為一個(gè)奔馳車主，官方建議4萬公里更換火花塞。此外，老款奔馳還存在制動開關(guān)損壞、空氣流量計(jì)等故障。

The short lifespan of spark plugs in Mercedes Benz cars is also a common problem, which can lead to a decrease in vehicle power, body vibration during acceleration, changes in exhaust noise, idle vibration, and other phenomena. As a Mercedes Benz owner, the official recommendation is to replace spark plugs after 40000 kilometers. In addition, the old Mercedes Benz also has faults such as damaged brake switches and air flow meters.
