AutoBeta(AutoBeta.net)05/07 Report--

In January this year, Ms. Huang bought a Mercedes-Benz GLB at a 4S store in Huzhou. The price was 360000, but only a few days after she bought it, the window went up and down, and the central control screen went black twice.

According to Ms. Huang, the GLB was picked up in January and there was a noise in the back window in mid-February. When it left in early March, the central control screen suddenly went black, and the screen went black twice.

There is an abnormal noise in the left rear window, which is eliminated after the treatment of the 4S store. For the problem of the central control black screen, the 4S store will upgrade the software to eliminate the fault. But on the day of the repair, as soon as Ms. Huang took the car away, a new problem appeared.

Ms. Huang's car has not yet walked out the door and found that the reversing video and voice functions are gone. The 4S store said that the system may not have been upgraded. After the second upgrade of the 4S store system, the car finally returned to normal.

But the car's malfunction is much more than that. in Ms. Huang's words, if the previous glitch is an "appetizer", then the next glitch is the "main course".

On March 24, the GLB had a left front fault (airbag failure). After testing, it was found that the plug was loose. The 4S store unplugged the central plug and reseated it, and then the fault code disappeared. When Ms. Huang drove back for a week or so, Mercedes-Benz had the same malfunction again, and until now, the central control of the car still showed a "left front failure" hint.

Ms Huang said it was the third time that the failure had occurred. The 4S store reseated the plug for the first time and replaced the airbag control unit for the second time, but only a day later, the alarm on the left front lit up again. In this regard, Ms. Huang hopes to return the car, because now the 4S store can not solve this problem.

Four months after buying the car, the luxury car has no sense of superiority, but there is a lot of trouble. For Ms. Huang's request, the after-sales manager of Huzhou Dexing 4S store said that he had fed back the relevant data to the manufacturer, but had not yet received a clear reply. As for the cause of the car's failure, the 4S store said it needed further testing. As for whether Ms. Huang's situation meets the standard of returning and changing cars, the 4S store has not given a clear answer.

Automobile experts of the Zhejiang Consumer Protection Commission said that a situation like the final failure light of the airbag can be considered as a serious safety performance failure, and if it has not been repaired twice, Ms. Huang can completely ask the 4S store to return and change the car. And the identification of this serious safety performance fault can not be identified until the accident is found, because in the event of an accident, there may be casualties. Finally, Ms. Huang said that she was willing to wait for the manufacturer's reply before negotiating with the 4S store.

The new car broke down frequently in less than half a year, and so far the fault has not been repaired. Mercedes-Benz, as one of the domestic luxury brands, has been among the best in sales, which to a certain extent reflects the strength of this brand. At the same time, a growing number of recalls and minor errors have caused more and more consumers to lose trust in the brand. In fact, there are many reports about frequent failures soon after the new Mercedes-Benz was bought. Although the problems are inevitable, it is hoped that manufacturers will still be able to pay attention to the quality of the brand and reduce the occurrence of failures.
