(1) 16 vehicles of the 2016 A-class, GLA and CLA series, with production dates from October 22, 2015 to November 4, 2015.
An error in the weld process and standard between the disc and hub of the above-described vehicle clutch may cause cracking and affect the power transmission of the vehicle. If cracked, the transmission will enter neutral or emergency mode and the vehicle will coast to stop, posing a safety hazard.
Mercedes-Benz (China) Automobile Sales Co., Ltd. will carry out an active recall of the above-mentioned vehicles, freely overhaul the vehicles, and replace the dual clutches to eliminate potential safety hazards.
(II) 12 vehicles of the 2015 AMG and GT series, with production dates from June 9, 2015 to July 22, 2015.
Due to the deviation of the production process of the supplier, the connection strength between the carbon fiber drive shaft and the flange of the vehicle is insufficient, and in some cases, the separation may occur, affecting the power transmission of the vehicle, and there is a safety hazard.
Mercedes-Benz (China) Automobile Sales Co., Ltd. will implement a voluntary recall of the above-mentioned vehicles, free maintenance of the vehicles, and replacement of carbon fiber drive shafts for problem vehicles to eliminate safety hazards.
The authorized service center of Mercedes-Benz (China) Automobile Sales Co., Ltd. will notify the relevant customers of the recall by means of a registered letter. At the same time, relevant customers can also call the service hotline to learn more about the recall. Users can also visit the AQSIQ website inspection and supervision department (jyjgs.aqsiq.gov.cn), the AQSIQ Defective Product Management Center website () and the WeChat public account (AQSIQDPAC) to learn more. information.

This powder is commonly used in applications where high wear resistance and hardness are required. It is often applied as a protective coating on surfaces that are subjected to abrasive or erosive environments, such as industrial equipment, cutting tools, and engine components.
The thermal spray process involves heating the powder to its melting point and then propelling it onto the surface to be coated using a high-velocity gas or plasma stream. Upon impact, the molten particles solidify and bond with the substrate, forming a dense and durable coating.
The chromium carbide coating provides excellent resistance against wear, corrosion, and oxidation. It also exhibits good adhesion to various substrates, including metals, ceramics, and composites. Additionally, it has a low coefficient of friction, making it suitable for applications where reduced friction and improved sliding properties are desired.
Overall, chromium carbide thermal spray powder is a versatile and effective coating material that offers superior protection and performance in demanding industrial applications.
