Official summary
IMPORTANT INFROMATION Your vehicle has an OPEN safety recall regarding the high-voltage battery. The vehicle’s high voltage battery might be insufficiently robust at a high State of Charge (“SOC”) - an internal short circuit of a battery cell in the high-voltage battery might occur, which could lead to the risk of a fire, within the high voltage battery. Until the remedy software update is performed on your vehicle, the maximum SOC for your vehicle’s high-voltage battery must be set to 80%.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
