Official summary
This bulletin replaces TSB 07-143-18R and announces additional changes made to the PRG control module. These changes are in response to a limited number of customer concerns regarding the rear gate not opening when operating the gate mounted switch, dashboard switch or the rear gate button on the key fob.
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.
