A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- [09\-022\-26](/bulletins/11035599.md), 2026-08-04, Service bulletin: ELECTRICAL SYSTEM; VISIBILITY/WIPER. This bulletin supersedes the previously issued bulletin\(s\) listed below. The changes are noted in Red text. 09\-042/04 12/10/04 DESCRIPTION Some vehicles may exhibit inoperative electric rear window defroster grid lines, integral antenna concerns causing radio reception issues or terminal tabs pulled from the rear window glass. Follow the diagnostic and repair procedures included in this service information to inspect and service rear defroster grid lines, integral antenna concerns or broken terminal tabs.
- [SA\-039\-23a](/bulletins/10243569.md), 2023-10-05, Service bulletin: STRUCTURE; VISIBILITY:POWER WINDOW DEVICES AND CONTROLS. Some vehicles may experience exterior trim heat damage when parked near a glass building or Low\-E windows. This may be caused by the sun's reflection.
- [SA\-040\-21](/bulletins/10198691.md), 2021-07-01, Service bulletin: VISIBILITY:POWER WINDOW DEVICES AND CONTROLS. Some vehicles may experience exterior trim heat damage when parked near a glass building or Low\-E windows. This may be caused by the sun's reflection.
- [MT\-003\-21](/bulletins/10198574.md), 2021-06-29, Service bulletin: VISIBILITY:POWER WINDOW DEVICES AND CONTROLS. Some vehicles may experience exterior trim heat damage when parked near a glass building. This may be caused by the suns reflection. If a building creates enough of a curve with a series of flat windows, which act like mirrors, the reflections all converge at one point, focusing and concentrating the light onto the street below.
- [07\-002\-19\-3616a](/bulletins/10169539.md), 2019-12-20, Service bulletin: EQUIPMENT; EQUIPMENT:APPLIANCE:AIR CONDITIONER; EQUIPMENT ADAPTIVE/MOBILITY. A musty/mildew type odor may come from the vents when the air conditioning \(A/C\) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/C evaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. “Mazda Air Cooling Coil Coating” is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years. NOTE: See parts information for Mazda Air Cooling Coil Coating and Kit part numbers.

- [07\-002\-18\-3432](/bulletins/10136782.md), 2018-05-14, Service bulletin: EQUIPMENT:APPLIANCE:AIR CONDITIONER. A musty/mildew type odor may come from the vents when the air conditioning \(A/C\) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/Cevaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. "Mazda Air Cooling Coil Coating" is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years. NOTE: See parts information for Mazda Air Cooling Coil Coating and Kit part numbers. This treatment provides a durable coating that will aid to prevent biological reactions that lead to odorconcerns. It is applied to the evaporator in a misted form that is introduced by way of the cabin air filter, the re\-circulate door, the blower motor resistor access, or the blower motor air intake. Proper application requires the evaporator surface to be: Relatively clean and free of leaves, dust build\-up and debris. Thoroughly dried, and the product cured onto it after application. NOTE: Keep the cooling unit dry by leaving the blower fan ON \(at least on low\), even if the A/C is not being used. In low humidity \(dry\) conditions, keep the ventilation system in the "FRESH" mode all the time, or as much as possible. In high humidity conditions, or if the air has a lot of dust or pollen, keep the system in the "RECIRCULATION" mode. A few minutes before reaching a destination, turn the A/C OFF, but leave the blower fan ON. This stops the accumulation of condensation on the evaporator/cooling unit, and it helps dry the inside of the cooling unit. A/C odor is not unique to Mazda vehicles as it will occur in other makes and models. To minimize A/C odor, suggest the following to the customers.
- [07\-002\-13\-2842](/bulletins/10097805.md), 2017-04-24, Service bulletin: EQUIPMENT:APPLIANCE:AIR CONDITIONER. A MUSTY/MILDEW TYPE ODOR MAY COME FROM THE VENTS WHEN THE AIR CONDITIONING \(A/C\) SYSTEM IS OPERATING. IT IS MOST NOTICEABLE WHEN THE A/C IS FIRST TURNED ON. THIS ODOR IS THE RESULT OF MOLD GROWTH IN THE A/C EVAPORATOR/COOLING UNIT WHICH IS CAUSED BY CONDENSATION, DUST, AND POLLEN WITHIN THE COOLING UNIT. THIS CONDITION IS USUALLY WORSE DURING HIGH HUMIDITY CONDITIONS. “MAZDA AIR COOLING COIL COATING” IS AVAILABLE TO ENCAPSULATE THE MOLD TO REDUCE ODORS. IF THE PRODUCT IS PROPERLY APPLIED, IT CAN EFFECTIVELY REDUCE THE MUSTY/MILDEW ODOR FOR UP TO THREE YEARS.NOTE:SEE PARTS INFORMATION FOR MAZDA AIR COOLING COIL COATING AND KIT PART NUMBERS.
