Official summary
Service Bulletin - While transitioning from Hybrid mode (engine on) to EV mode, the PGM-FI ECU adjusts the crank position for best location of engine start. A software programming error during this transition results in the PGM-FI ECU resetting and inappropriately erasing stored memory data in the PGM-FI ECU. In some cases, the Malfunction Indicator Lamp (MIL) may be set as a result.
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.
