Official summary
Some vehicles may exhibit a delayed engine start or experience poor acceleration while driving in EV mode when the battery is at a low state of charge (SOC). This is caused by improper control logic of the PCM. To eliminate this concern, the control software of the PCM has been modified.
Vehicles covered
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.
