What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Some customers may complain of an engine restart failure after i-stop activation, following a stop after low-speed driving (below 20 km/h). Engine restart is possible with key operation. This problem occurs when an IR request happens during an extremely short period (a few milliseconds) while transitioning to i-stop control, such as when the brake is released. In this case, the engine may fail to restart due to improper i-stop control. This concern has been eliminated through a PCM control software modification.

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. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 4 model years this bulletin names have filed 94 complaints with NHTSA since 2015. 13 of them name Engine — 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.
My 2023 Mazda 3 started to have a more terrible and annoying rattle after 3000 miles. The engine will resonate and knock when it reaches a certain speed. The slow speed light throttle acceleration rattles. The most annoying thing is the multiple rattles inside, dash, door panels, and roof. It is like a can in the summer.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda 01-005-25 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 01-005-25 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 01-005-25 cover?
The manufacturer filed it against 4 model years: 2023 Mazda CX-30, 2022 Mazda CX-30, 2023 Mazda Mazda3, 2022 Mazda Mazda3. 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: 2022-2023 CX-30 (Mexico built): built before 1 Sep 2023; 2022-2023 Mazda3 (Mexico built): built before 11 Sep 2023 — the build date is on the certification label in the driver’s door jamb.
