Official summary
The EPC light is illuminated. DTCs are stored in the engine control module. Due to a software error, the ECM can falsely record engine misfires in the primary detection window. No actual engine misfires are present until the EPC light is illuminated and the ECM hides a cylinder.
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.
