- Beijing Benz is recalling 13,447 domestically produced EQC vehicles starting September 27.
- Due to a design flaw in the battery management system software, the high-voltage batteries may experience thermal runaway under extreme conditions.
This is the second recall in the past three months initiated by Mercedes-Benz in China due to battery fire risks.
Beijing Benz, Mercedes-Benz's joint venture in China, is recalling 13,447 locally produced EQC vehicles produced between November 30, 2018, and September 17, 2022, starting September 27, according to an announcement today on the website of China's State Administration for Market Regulation (SAMR).
Due to a design flaw in the battery management system software, the high-voltage batteries in these vehicles may experience thermal runaway under extreme conditions, according to the announcement.
This could lead to vehicle fires and pose a safety hazard, the announcement said.
The recall is being conducted under SAMR's defect investigation, and Beijing Benz will upgrade the battery management system software of the affected vehicles through authorized dealers.
Before formal recall measures are implemented, Beijing Benz recommends that users set the charging limit of the vehicles to no more than 80 percent.
The EQC is Mercedes-Benz's first electric vehicle, initially launched in China in November 2019. In early 2022, Mercedes-Benz faced widespread complaints from Chinese owners over motor issues with the EQC.
Mercedes-Benz's last recall announcement involving EVs was in March, when it recalled 12,308 domestically produced EQA and EQB vehicles.
Production process issues with the high-voltage batteries in some vehicles increased the risk of internal short circuits in the battery cells, potentially leading to vehicle fires, according to an announcement on March 28.
SAMR's website publishes recall announcements almost every month, with battery-related recalls occurring from time to time.
Mercedes-Benz said it will cut redundant roles in China, and consolidation of the business will inevitably involve some staff.
