Core Viewpoint - Volkswagen is recalling a total of 44,551 ID.4 electric vehicles in the U.S. due to potential safety hazards related to the high-voltage battery system [2][4]. Group 1: Recall Details - The first recall involves 670 units of the 2023-2024 ID.4 models, due to a manufacturing defect in the battery cell module that could lead to battery fires [2]. - A second, larger recall affects 43,881 units of the 2023-2025 ID.4 models that lack "self-discharge detection" software, which may also pose a fire risk [2][3]. - Volkswagen recommends affected owners set their charging limit to 80%, avoid DC fast charging, and park their vehicles outdoors after charging [2]. Group 2: Supplier and Battery Issues - Both recalls are linked to SK Battery America, which supplies the high-voltage battery cell modules [3]. - There have been at least five overheating incidents involving the ID.4 in the U.S. from 2024 to 2025, attributed to a hardware anomaly known as "electrode misalignment" [3]. - Electrode misalignment is a critical quality issue in battery manufacturing, where deformation causes the positive and negative electrodes to misalign [3]. Group 3: Market Impact and Context - The ID.4 is a core product in Volkswagen's global electric vehicle strategy, with global sales reaching 163,400 units in 2025, a 26.8% increase year-on-year [4]. - Volkswagen has not reported any incidents of fire or injuries related to these specific defects, emphasizing that the recall is a proactive measure [4]. - Other brands under Volkswagen, such as Bentley, have also faced battery safety issues, indicating a broader concern within the industry regarding battery supplier quality [4].
