Official summary
Some customers may complain that their seat warmers or seat ventilation do not turn on when the engine is restarted after being left on when turning off the engine. The logic has changed from previous Mazdas where the seat warmers and seat ventilation automatically turned on when the engine was restarted.
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.
