Official summary
Our records indicate that a PRODUCT UPDATE has not been completed on this vehicle; refer to the address card for the affected VIN. The software controlling the IMA battery on your vehicle incorrectly maintains the battery and, over time, the battery develops a memory effect that appears as a reduction in battery capacity. If the software is not updated, it is likely that the vehicle may set a code falsely indicating a deterioration of the battery pack, or the battery level gauge may suddenly drop to empty and start charging unnecessarily.

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.
