AutoBeta(AutoBeta.net)08/04 Report--

According to relevant media reports, a Mercedes-Benz owner in Zhengzhou started the car the next day, and the central control display black screen appeared, and the on-board system could not be used normally. And the car has been repaired three times in a month, but the store has not given a solution.

On June 7 this year, Mr. Zheng spent about 400000 yuan to buy a Mercedes-Benz E260 in Zhengzhou Penglong Wantong Automobile sales Co., Ltd.

June 8, that is, the day after picking up the car. When Mr. Zheng drove his new car under normal driving conditions, the central control screen suddenly went off, and there was no response when he clicked on the open button.

Mr. Zheng said that because the vehicle screen does not display, so the reversing image, music, USB Jack and other functions can not be used. The small screen behind the steering wheel also indicates that some functions are stopped.

So he quickly contacted the 4S store and carried out a series of operations under the remote guidance of the staff, but to no avail. The staff told him that the mainframe system might need to be upgraded and asked him to go to the store to check.

As a result, the monitor suddenly turned on again the next morning. This made Mr. Zheng think that the anomaly was accidental, but it was just the beginning.

"over the past month, failures have occurred frequently. I have run to the 4S store at least a dozen times and made numerous phone calls, but they have not been solved." Mr. Zheng said that in early July, staff at the 4S store upgraded the mainframe and waited four or five hours to repair the vehicle because of the same problem. However, before I got home from the 4S store, the problem appeared again.

Therefore, Mr. Zheng completely lost trust in the vehicle and asked the store to return the car. But the 4S store said it did not meet the three-pack rule and could not be refunded. Only put forward the plan of replacing one mainframe as a whole and extending the warranty.

In this regard, Mr. Zheng said that it was unacceptable, on the one hand, he was worried that there were other quality problems with the vehicle, and on the other hand, it was because the car he had just bought had problems the next day, and he had to dismantle and replace the parts. And suspect that there is a quality problem with the vehicle, otherwise how could there be a problem in less than a day?

After that, Mr. Zheng asked a reporter to go to the 4S store for negotiation. For vehicles that have problems so quickly, an after-sales manager in the store said that every car they deliver will be strictly tested, but not necessarily the vehicles will not have problems, and according to the manufacturer's reply, they can only replace the mainframe assembly parts for the failure, and that the host of the control screen is abnormal, which does not affect the normal driving function.

The after-sales manager also said that although the mainframe only responsible for the screen unit is broken, but to be on the safe side, decided to replace the entire mainframe, after the replacement is basically impossible to have a similar problem.

As for the problem of "constant speed cruise control and speed limit control stop working" that Mr. Zheng is worried about, the manager explained that the Mercedes-Benz constant speed cruise system can be removed by pressing the button, braking and putting in neutral, and the probability that the three methods will fail at the same time is almost zero.

According to the after-sales manager, Mr. Zheng's car, whether in accordance with the three packages or the new car quality assurance policy, does not meet the conditions for return and exchange. The main parts can only be returned and replaced if there is still something wrong with the maintenance for 5 times.

"We can understand Mr. Zheng's feelings." After-sales manager said that after the replacement of the mainframe, if Mr. Zheng is not assured, he can extend the warranty period, the specific time can be communicated and discussed. The next step will be to actively communicate with Mr. Zheng and strive for a solution as soon as possible.

After a long period of communication, the two sides finally reached an agreement.

How to define the main components? Mercedes-Benz official website shows that the range of major assemblies and major parts is subject to the three-pack certificates of Mercedes-Benz passenger cars and smart-branded passenger cars, and the recall and active service measures do not apply to this policy. Specifically, it includes some parts of engine, transmission, steering system, braking system, suspension system, front / rear sedan chair, car body and so on.
