Official summary
If you encounter the hazard warning lights staying on after a dash repair, you may have crossed the hazard warning switch connector with another connector, such as the bluetooth microphone connector. The two connectors have the same number of pins.
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.
