09-036-242024-08-02. Service bulletin. SEATS. At PDI or when new vehicle is delivered, some customers may complain about wrinkles on the leather seat cushion and/or seat back surface. NOTE: This repair is not a permanent fix, it is meant to make new seats look their best when the vehicle is first presented to the customer. • Wrinkles may not be completely removed after the repair is completed. • Leather is a natural material and may develop some wrinkles due to aging and wear during normal useage.
09-035-242024-08-02. Service bulletin. ELECTRICAL SYSTEM; SEATS. Some vehicles may experience the seat ventilation system still on after the engine has been turned off, in some cases this causes the battery to be completely discharged and not rechargeable. This is caused by a deterioration in the seat ventilation control unit. To eliminate this concern, the material for the circuit of the seat ventilation control unit has been modified.

SA-007-212021-02-06. Service bulletin. SEATS.

SA-016-202020-02-04. Service bulletin. SEATS. 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. NOTE: Customers in cold weather are more likely to complain about this if their vehicle is equipped with Mazda Mobile Start (MMS) (not available on Mazda3 or CX-30) because the MMS accessory instructions state the seat warmers WILL turn on when the engine is restarted. The same can happen in the hotter weather with the seat ventilation. This information is incorrect for these vehicles. Both features will now require a manual setting every time the vehicles are restarted after being turned off. Consult the vehicle’s owner’s manual for more details on proper seat warmer/seat ventilation operation.
