AutoBeta(AutoBeta.net)05/25 Report--

Ms. Shen of Shaoxing revealed to the media that she had a Mercedes-Benz C260 sedan. Since the car was picked up, the car has constantly jumped the trouble lights, updated the system and changed the generator, but the problem of the vehicle has not been solved. After asking and selling, the reply given by the other party said that they did not know.

She bought a Mercedes-Benz C260 from Shaoxing Star in December 2019 and jumped out of the fault light after driving 61 kilometers, Ms. Shen said. On December 13, 2019, the car was picked up, and on the 19th, there was an exclamation point in the middle of a red car, and then there was an exclamation point in the middle of the 48-volt motor failure. The car was dragged to the 4s store for a software update for 5 minutes. On the 21st, the vehicle had the same problem again, and then continued with the software update.

Last March, the fault light was on for the third time, and this time it showed that there was a fault in the power system of a 48-volt car. Please refer to the user's manual. Finally, I went to the 4S store to upgrade the system. In May, the fault light came on again, and the dashboard display was the same as the first time. 4S said that if the generator was not replaced, the problem could never be solved. Ms. Shen then changed it, and the car started normally after changing the 48-volt motor, but this month the car jumped out of the fault light for the fifth time, showing that the 48-volt power system failed. Please refer to the user's manual. The situation is the same as the third time. The solution given by the 4S store this time is to upgrade the system. Ms. Shen then asked after-sales: what will happen next? I don't know if the after-sales response can be solved. I don't know if it will happen again. I don't know if it can be eradicated. Ms. Shen said that because the vehicle is light mixed, 1.5T engine and 48 volt generator operate together, whether this will affect my life and safety, the other party's answer is still unknown.

For Ms. Shen's vehicle, after-sales manager Zhang of Shaoxing Star said: from the data, we feedback the past, the manufacturer will analyze the background data of the whole car, after the second upgrade, the third time may be repeated upgrade, can not solve the problem, it may be necessary to replace parts, for the media asked about the same situation a year later, Manager Zhang said that for this time It is the manufacturer that sends a new software regularly. Well, according to the normal operation procedure, when we encounter this fault, the system needs to be upgraded. As to what the fault code reflects, Manager Zhang said, this is actually a piece of data inside. The actual value of the data may not match for a normal car, or it may be a situation in which the data goes up and down, so upgrading needs to be done in this area. Manager Zhang said that not every time the software sent by the manufacturer, every car needs to be upgraded, this is to see the car.

Manager Zhang said that after this upgrade, the fault code was eliminated, and after it was eliminated, the maintenance was over. Will also continue to communicate with manufacturers, eliminated after the follow-up will not have such a problem. When the media asked whether it was a normal frequency for Ms. Shen's car to break down so frequently, Manager Zhang said that according to the situation of the car, it was less than two years, a little more.

Ms. Shen said that the car belongs to the light hybrid 48 volt motor system, which belongs to the car's power system, should be counted as engine parts and has been repaired five times to meet the return conditions. Manager Zhang said that this is a separate system, according to the three-package method, according to the provision of 50000 kilometers in two years, maintenance must be up to five times, and this piece is also being verified with the manufacturer. There is a dispute between the third and the fourth time, because the customer was asked to replace the generator the third time, but not at that time. It will not be changed until the fourth time, whether it counts this time or not depends on the results verified by the manufacturers. Manager Zhang said that another question is to determine whether it is the same problem these five times. It is possible to see so many 48 volts, is it the same question behind it, and whether Ms. Shen's car has reached the return and exchange conditions or not, we have to wait for the manufacturer to reply.

It is worth noting that last year, Miss Shen also revealed to the media that she had bought a Mercedes-Benz C260 sedan at Shaoxing Star 4S store. About half a month after the new car was bought, the car broke down three times and broke down on the same day it was picked up.

Ms. Shen said that the wireless charging function of the Mercedes-Benz C260 she bought could not be used when it was picked up. After testing by the maintenance staff at the 4S store, it was found that the wireless charging function could not be used because of a system failure. The maintenance personnel then upgraded the system to eliminate the fault code.

After the code was eliminated, the wireless charging function showed normal use, but the new fault light came on again on the fourth day of the lift. This time it showed an engine failure, and Ms. Shen then drove the vehicle to the 4S store, where maintenance personnel said the vehicle's system was malfunctioning and needed to be upgraded to eliminate the code.

But the day after the upgrade, the engine fault light lights up again, the pop-up fault is the 48 volt vehicle power system failure, please refer to the user manual.

Why do the same problems occur frequently? in view of the failure of the power system of the Mercedes-Benz C260, we also searched the Internet, and it is not difficult to find that there are quite a lot of such failures, and many car owners say they encounter the same problem. and the power system failure occurred soon after the car was picked up.

In view of this problem, we will continue to pay attention to how the follow-up manufacturers will deal with it.
