Mazda has developed factory recommended scheduled maintenance services that support all major vehicle systems. Mazda recommends dealers follow the scheduled maintenance tables as cited in the vehicle- specific workshop manual or owner's manual. Services performed outside of Mazda's factory scheduled maintenance are not recommended. These services are unnecessary and create unneeded expenses for your customers.

Some customers may experience that after starting the engine, the auto A/C blows warm air for about 10 minutes and then blows cool air as desired. This concern occurs when the ambient temperature is within a certain range (approx. 16-25 C / 61-77 F). This is caused by the control software of the Dash-Electrical Supply Unit (Dash-ESU) not being appropriate for this specific situation. To correct this concern, the control software of the Dash-ESU has been modified.

Some customers may complain about poor heater performance even after the engine reaches normal operating temperature. This may be caused by a plugged heater core. For 2014-2016 Mazda6 and 2013-2016 (US spec) / 2017 (Mexico spec) CX-5, the CHECK ENGINE light may turn on with DTC P011A:00 (ECT sensor No.1/No.2 performance problem) stored at the same time. NOTE: Refer to TSB 01-015/15 if the customer is using a block heater at temperatures below freezing. To solve this concern, two mass production changes have been implemented. a) The concentration of the coolant has been increased so that the amount of the contained anti-rust additive is higher. b) The composition of the coolant has been changed (the ratio of the anti-rust additive has increased).
