Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda MSP64 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 MSP64 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 MSP64 cover?
The manufacturer filed it against 3 model years: 2025 Mazda CX-70, 2025 Mazda CX-90, 2024 Mazda CX-90. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built 6 Jan 2023 – 28 Feb 2025; CX-70 PHEV JM3KJ**** S1 100056 – 127962: built 14 Dec 2023 – 28 Feb 2025 — the build date is on the certification label in the driver’s door jamb.
