Mercedes-Benz’s joint venture in China, Beijing Benz, has announced a recall of 13,447 domestically produced EQC vehicles due to a design flaw in the battery management system software. The recall is set to begin on September 27 and affects vehicles produced between November 30, 2018, and September 17, 2022.
The high-voltage batteries in these vehicles may experience thermal runaway under extreme conditions, which could lead to vehicle fires and pose a safety hazard. To address this issue, Beijing Benz will upgrade the battery management system software of the affected vehicles through authorized dealers.
Prior to the formal recall measures, users are advised to set the charging limit of the vehicles to no more than 80 percent as a precautionary measure. This recall marks the second in the past three months initiated by Mercedes-Benz in China due to battery fire risks.
The EQC, Mercedes-Benz’s first electric vehicle, was initially launched in China in November 2019. However, the company has faced challenges with the model, including motor issues that led to widespread complaints from Chinese owners in early 2022.
In a previous recall in March, Mercedes-Benz recalled 12,308 domestically produced EQA and EQB vehicles due to production process issues with the high-voltage batteries. These issues increased the risk of internal short circuits in the battery cells, potentially resulting in vehicle fires.
The State Administration for Market Regulation (SAMR) website regularly publishes recall announcements, with battery-related recalls occurring from time to time. It is essential for car manufacturers to address such issues promptly to ensure the safety of their customers and maintain the reputation of their brand.
