Mazda service campaign MSP61
Mazda filed this with NHTSA as a service campaign dated Jun 11, 2026, received Aug 5, 2024, about the unknown or other — 8 documents under this number: MSP61 Warr b, MSP61 Repair b, MSP61a Warranty, MSP61a Repair and more. It names 2 model years (2024). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationMSP61 - 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda MSP61 a recall?
No. A service campaign is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the MSP61 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does MSP61 cover?
The manufacturer filed it against 2 model years: 2024 Mazda CX-30, 2024 Mazda Mazda3. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
