Official summary

Service Bulletin for Lengthening the Backup Light Harness. Though the backup light harness is long enough to connect to the backup light switch, it may be short enough that the wire seals in the connector can be stressed. Moisture entering through the seals can cause corrosion, resulting in a bad connection and/or failure of the switch. As a result, backup lights and, if equipped, the backup alarm, may not function when the vehicle is shifted into reverse.

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.
