AutoBeta(AutoBeta.net)07/21 Report--

The rigorous German craftsman spirit has made a mistake again. A few days ago, Mercedes-Benz China filed a recall plan with the State Administration of Market Supervision and Administration, recalling some imported C-class and CLS-class cars from now on because the bolts were installed incorrectly.

Mercedes-Benz explained that the installation bolts of the engine turbocharger return pipe and crankcase ventilation pipe of the vehicle within the recall range may be mixed. Due to the difference of bolt specifications, the pretightening force of the connection may be insufficient, which affects the tightness of the connection between the turbocharger return pipe and the bolt. in extreme cases, the risk of fire can not be ruled out and there is a safety hidden danger.

Mercedes-Benz's solution is to replace the installation bolts of the correct turbocharger return pipe and crankcase ventilation pipe for the affected vehicles free of charge to eliminate safety risks.

Netizens have made fun of "rigorous Germans", pointing directly at Mercedes-Benz quality control. Some netizens even think that if a domestic car makes such a low-level mistake, it must be blown badly!

In fact, car recalls generally involve product design or supplier problems, and quality control problems such as repeated assembly errors of Mercedes-Benz are rare in the industry.

In April this year, the General Administration of Customs issued a warning notice on the hidden danger of mismatching of ternary catalytic converters in some imported Mercedes-Benz cars. when the customs carried out environmental protection verification on imported cars, it was found that the models of ternary catalytic converters of imported cars, including Mercedes-Benz GLE, GLE Coupe and GLS, were not consistent with the environmental protection publicity models. According to the investigation, 279 cars have been delivered to users, 29 cars are in stock at dealers, and a total of 308 imported Mercedes-Benz cars have problems.

Mercedes-Benz Chinese officials explained that the reason for the mismatch of ternary catalytic converters was that the factory's old vehicle feeding IT system failed to check the consistency of the initial models of GLE, GLE Coupe and GLS, resulting in the mixed installation of ternary catalytic converters for some vehicles. The solution is to effectively eliminate it by replacing the correct ternary catalytic converter.

Mercedes-Benz China filed a recall plan with the General Administration of Customs in August 2018, recalling a total of 164imported Mercedes-Benz E 43 AMG 4MATIC vehicles because they were not equipped with active braking assistance systems. That is, the active brake configuration that should have been installed in the original factory is not installed, such as distance warning, autonomous braking and brake assistance depending on the situation can not be used, increasing the risk of collision. Mercedes-Benz explained that it was caused by an error in the production documents, resulting in a complaint and claim.

In addition, the hot Xi'an Mercedes-Benz oil spill rights incident, the Mercedes-Benz for an imported CLS300 model worth more than 600,000 yuan, was finally confirmed that the engine in the original factory assembly process of the oil splash plate fixed bolts left in the engine, high-speed operation led to cylinder body was broken down to cause oil leakage, belonging to assembly defects.

Even if the recall is a responsible performance of the manufacturer, in the view of many netizens, such a low-level mistake should not appear in such a big factory and luxury brand. After frequent quality problems and recalls, Mercedes-Benz's sales in China remain unaffected. In the first half of 2019, Mercedes-Benz China's cumulative sales reached 344657 vehicles, an increase of 1.3% over the same period last year, only slightly behind BMW China, ranking second among luxury brands.
