Official summary
Owner Notification Letter - Your vehicle may be equipped with an improperly functioning on-board emission-related diagnostic system that violates California and Federal standards and regulations. While transitioning from hybrid mode (engine on) to EV mode, a software programming error 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.
