Mazda filed this with NHTSA as a service bulletin dated Dec 12, 2025, received Jan 3, 2026, about the engine. It names 5 model years (2024–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.
The 7G large platform utilizes a new 8-speed automatic transmission. Due to changes in the parking lock mechanism, which is now hydraulically operated, the neutral range in the transmission can only be achieved if the engine is running (or “Ready-On” for PHEV). With this design, there is no provision to manually engage neutral. This can cause challenges to dealers, customers, or towing providers when a vehicle cannot start and can't move, usually due to a discharged (dead) battery. In the event that a vehicle cannot be started or achieve “ready-on”, wheel dollies must be used to allow the vehicle to be rolled and moved. NOTE: The following procedure is for moving vehicle around the service shop and not for towing purposes. Please reference the owner's manual for towing instructions.

What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 587 complaints with NHTSA since 2015. 233 of them name Engine, Electrical System, Power Train — 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.
I own a 2026 Mazda CX-90 hybrid with approximately 13,000 miles. The vehicle began making a grinding noise while driving, which has progressively worsened over time. It has since developed a hard knocking noise accompanied by noticeable vibration when the vehicle shifts gears. This knocking occurs during normal in-town driving.

My boyfriend and I rented the car from Hertz Car Rental in on Labor Day weekend. Within moments of driving the car off the lot, the safety camera system stopped working and the lights came on saying they weren’t working. The touch screen also started glitching and intermittently working but we didn’t think too much about it.

My car is literally stalling out on me. It started by sputtering when I put my foot on the gas a week or so ago. Then today It literally started just losing power while driving. It’s not throwing any codes but that’s super dangerous and this car is only a year old. I am extremely concerned for my safety

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda SA-058-25 a recall?
No. A service bulletin 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 SA-058-25 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Mazda warranty extension on file lists the ones Mazda has filed.
Which vehicles does SA-058-25 cover?
The manufacturer filed it against 5 model years: 2026 Mazda CX-70, 2025 Mazda CX-70, 2026 Mazda CX-90, 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.
