Mazda bulletin SA-052-24
What it saysSome customer's might state that they notice fluid or oil leaking/dripping on the ground when the vehicle is parked. NHTSA’s full summary ↓
Mazda filed this with NHTSA as a service bulletin dated Aug 7, 2024, received Sep 4, 2024, about the power train. It names 60 model years (2016–2025). 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 communicationSome customer's might state that they notice fluid or oil leaking/dripping on the ground when the vehicle is parked. For this concern, inspect the vehicle for any trace of a fluid or oil leak and use the following examples as a guide to determine if it is severe enough to require a repair, or just to clean the area and monitor it at the next service.

What owners reported
Source: NHTSA complaint databaseOwners of the 60 model years this bulletin names have filed 3,993 complaints with NHTSA since 2015. 1,303 of them name Engine, 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.
On the 2016 Mazda CX-5, the 41 owners who gave an odometer reading for Power Train reported it at a median of 5,411 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Manual transmission synchronizers fail, causing erratic gear shift operation and the inability to change gears, which could result in an accident. The ND Mazda Miata Owners Group on Facebook has polled its owners and found a 10% failure rate of manual transmissions among owners in the group who required replacement of the transmission.

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 SA-052-24 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-052-24 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.
Which vehicles does SA-052-24 cover?
The manufacturer filed it against 60 model years: 2021 Mazda CX-3, 2020 Mazda CX-3, 2019 Mazda CX-3, 2018 Mazda CX-3, 2017 Mazda CX-3, 2016 Mazda CX-3 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
