LI AUTO(US:LI) Di Yi Cai Jing Zi Xun·2025-11-02 05:53Core Viewpoint - The recall of approximately 11,000 units of the Li Auto MEGA 2024 model due to insufficient corrosion resistance of the coolant has raised significant safety concerns and highlighted the importance of quality control in the electric vehicle industry [1][6]. Group 1: Recall Details - Li Auto announced a recall of about 11,000 MEGA 2024 models to replace the coolant, battery, and front motor controller due to potential safety hazards from coolant leakage [1]. - The coolant in question has been identified as having inadequate corrosion resistance, which can lead to battery short circuits and potential fire incidents under specific conditions [1][4]. Group 2: Industry Concerns - Industry experts have raised questions about the rarity of coolant corrosion issues in new vehicles, especially those less than two years old, and the adherence to national standards for coolant production [1][4]. - The rapid pace of electric vehicle development and shortened testing cycles have led to concerns about ensuring vehicle safety amidst competitive pressures [6][7]. Group 3: Coolant Specifications - Electric vehicle coolant is a functional liquid composed of antifreeze and corrosion inhibitors, designed for thermal management of the battery system [2]. - The coolant's conductivity and corrosiveness pose risks if it penetrates the battery pack, potentially causing short circuits and thermal runaway [2][4]. Group 4: Testing and Quality Control - The national standards for electric vehicle coolant require rigorous testing, including static and cyclic corrosion tests, to ensure safety and performance [4][6]. - Despite stringent testing requirements, the failure of the MEGA's coolant to meet corrosion standards raises questions about the quality control processes within the company [6][7].
