NHTSA's summary

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.

09-028-232023-08-03. Service bulletin. Some CX-5 and CX-30 customers may find that the liftgate does not close when pressing the power liftgate (PLG) rear switch (A) located on the interior liftgate trim. This may be caused by PLG switch corrosion. Water from a high pressure car washer and/or condensation may drip onto the switch connector and cause corrosion. To eliminate this concern, the PLG rear switch has been modified with a waterproof connector.
SA-036-232023-07-05. Service bulletin. Interior parts made of resin have antistatic coating to prevent dust from sticking on the surfaces, and depending on the conditions of use, the antistatic components may crystallize slightly, giving an appearance of white stains on the surface. To remove the stains, wipe the stained surface with a towel soaked with water mixed with a small portion of a neutral detergent. If the white stains reappear again, simply wipe them again in the same way. NOTE: The antistatic effect does not deteriorate with this procedure.
SA-012-232023-04-04. Service bulletin. Some customers may report an odor or water in the HVAC system and upon inspection, the cabin air filter may be found to be wet.
