Read by machine from the document NHTSA serves (3 pages), read Sep 30, 2026. A part number is shown only where it matches Mazda’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
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.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 519 complaints with NHTSA since 2015. 163 of them name Engine, Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
Vehicle is in normal mode with EV mode engaged, car is going 70mph and suddenly accelerator stops working and decelerates to ~60mph until vehicle suddenly aggressively switches to gas mode and accelerates again

After starting the vehicle and driving it for a short distance, I forgot to disable the engine start/stop function. When the engine shut down, I pressed the button to disable it as I loathe this feature.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda SSPD9 a recall?
No. A warranty extension 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 SSPD9 repair free?
A warranty extension 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 SSPD9 cover?
The manufacturer filed it against 2 model years: 2025 Mazda CX-70, 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: 2024 CX-90 JM3KK**** R1 100054 - 172250: built 28 Dec 2022 – 7 May 2024; 2025 CX-70 JM3KJ**** S1 100013 - 109070: built 5 Dec 2023 – 7 May 2024 — the build date is on the certification label in the driver’s door jamb.
