SummaryA 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.

SummaryMSP61 - MAZDA SERVICE PROGRAM - 2024 CX-30 AND 2024 MAZDA3 - CONNECTIVITY MASTER UNIT (CMU) SOFTWARE CONCERN. Mazda Service Program (MSP61) – 2024 CX-30 and 2024 Mazda3, equipped with 6 speakers Connectivity Master Unit (CMU) software concern: When using a Bluetooth® connected smartphone and talking with handsfree function on a vehicle with 6 speakers, the person on the other end of the line may have difficulty hearing the driver’s voice. Causal factor: Inappropriate Connectivity Master Unit (CMU) software. There are 65,022 vehicles in the U.S. and U.S. Territories. Mazda Motor Corporation has decided to conduct one Mazda Service Program (MSP61) and one Special Service Program (SSPD7) affecting vehicles in the U.S. and U.S. Territories. Mazda vehicles in Canada and Mexico are also affected by SSPD7 and must be repaired if presented to your dealership. There is some overlap in the VIN population and certain vehicles are affected by both campaigns. ACTION ITEM: There are approximately 2,800 (SSPD7) and 11,000 (MSP61) vehicles in stock at U.S. Mazda dealers which must be repaired as soon as possible. All Mazda dealers must quarantine any affected new, used, or CPO in-stock vehicles until the repair is completed. The affected dealer inventory list was provided to your District Service Manager with the notification of this dealer email. Once completed, the car can be delivered, and the Warranty claim can be submitted later without penalty since the car has been repaired. Repair Synopsis: Both campaigns require software updates. SSPD7 uses MDARS to update and should be performed after MSP61 if the vehicle has both campaigns. MSP61 updates the software via a USB stick. A Battery charger will be required to stabilize battery voltage. There are no parts involved with either campaign.

SummaryThe new AWD rear differential DOES NOT come with a breather cap on the rear of the differential, therefore a new one will need to be ordered and installed when replacing the differential. NOTE: The breather threads have a sealant and locking compound that prevents it from being reused. Refer to GEPC for the correct part number of the Differential Breather. The instructions on MGSS will be updated soon to include replacing the breather when replacing the differential with a new unit.

The part where the sunvisor connects is broken, so the spring cannot hold the sunvisor in the fully retracted position.

SummaryCustomers may report no audio when using the infotainment fader function fully adjusted to the rear. If the customer's vehicle is among the trim levels referenced above it is equipped with a 6-speaker infotainment system and does not include rear door speakers even though there are speaker grills/covers in the rear door panels. MazdaUSA and published vehicle specifications provide the correct information indicating that these trims are equipped with a "6-speaker audio system". This is a normal condition of the "6-speaker audio system" and current Mazda CONNECT fader function. Rear speaker diagnosis is not necessary as they are not equipped.

SummarySome vehicles may exhibit a deformed fuel-filler lid panel (1) attached to the fuel-filler lid box, resulting in a poor appearance. This concern is caused by the lid box not having enough water drainage capability which leads to the accumulation of water inside it. The water then freezes in cold weather and expands or the inner side of the lid panel absorbs the water and swells from long exposure, deforming the lid panel. To eliminate this concern, the shape of the fuel-filler lid box has been modified to have better drainage capability and a modified fuel-filler lid panel service part has been established for less water absorbance.
