Samsung SDI Recalls High Voltage Batteries Over Fire Risk

Samsung SDI

Samsung SDI, a South Korean battery manufacturer, has initiated a recall of high voltage battery packs due to a potential fire risk. The recall, which could impact up to 180,196 vehicles, was issued in response to a safety concern identified by the National Highway Traffic Safety Administration (NHTSA).

Potential Fire Risk in High Voltage Batteries

The recall affects certain high voltage battery packs used in vehicles produced between July 2020 and March 2023, including models from Chrysler, Volkswagen, Audi, and Ford. The faulty battery packs may fail, resulting in a loss of drive power, which significantly increases the risk of a crash. Additionally, the failure could also raise the risk of a fire, posing a severe safety hazard.

Cause of the Recall and Affected Vehicles

Samsung SDI has attributed the issue to variability in its production process, which can cause micro defects in the cathode or create local stresses in the separator. These production flaws could contribute to the potential safety risks. Chrysler, under Stellantis, is most affected, with 155,096 vehicles impacted by this recall.

Initially, Samsung SDI attempted to address the risks with a software remedy, but further investigation revealed that the software solution may not fully address certain abnormal conditions. Samsung SDI acknowledged that a more effective solution is required, and the recall remains active until the issue is resolved.
