Official summary
The infotainment system privacy setting “Allow data transmission” may, in unfavorable circumstances, change without user intervention. As a result, the vehicle sends data although this function was previously deactivated manually. The campaign code was reactivated for affected vehicles that are also included in Compliance Recall 90TV. THIS UPDATE MUST BE COMPLETED BEFORE PERFORMING COMPLIANCE RECALL 90TV.
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.
