Official summary
Some vehicles may exhibit the "Check Fuel-filler Cap" message displayed in the instrument cluster. This is caused by improper control software of the PCM. When the room fuse is installed and i-stop is activated, the message will display in the instrument cluster for three seconds only one time and no message will return. 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.
