Mazda filed this with NHTSA as a service bulletin dated Jun 5, 2023, received Jul 5, 2023, about the power train. It names 5 model years (2017–2020). 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 owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 277 complaints with NHTSA since 2015. 12 of them name 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.
Situation: CVT tramsmission running smoothly when car was first bought. I AM 3 weeks into owning the vehicle and the transmission seems to be going out. I had a diagnostic text run and there are zero computer errors. Issues: high revs and jerking of vehicle when gassed. Whether I AM at a stand still or already giving gas.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda 05-003-23 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 05-003-23 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 05-003-23 cover?
The manufacturer filed it against 5 model years: 2017 Mazda CX-5, 2020 Mazda Mazda6, 2019 Mazda Mazda6, 2018 Mazda Mazda6, 2017 Mazda Mazda6. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
