Some customers may complain about a noise from the engine compartment at idle. This may be caused by the fuel injection learning cycle at idle from the high pressure fuel pump. 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.
