Service bulletins for the 2024 Mazda Mazda3

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.

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.
