Mazda filed this with NHTSA as a service bulletin dated Aug 21, 2024, received Sep 4, 2024, about the service brakes. It names 62 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 owners reported
Source: NHTSA complaint databaseOwners of the 62 model years this bulletin names have filed 3,994 complaints with NHTSA since 2015. 336 of them name Service Brakes — 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 51 owners who gave an odometer reading for Service Brakes reported it at a median of 28,350 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2016 Mazda Cx-5. The contact stated that while attempting to stop at 20 MPH, the brake pedal was depressed and failed to respond. The contact stated that while the brake pedal was depressed, the vehicle accelerated continuously. The vehicle was able to be stopped after the brake pedal was depressed to the floorboard.
2016 Mazda CX-5 · Service Brakes · filed with NHTSA Dec 23, 2015
On April 16, 2022, around 6:45PM, I drove my new Mazda CX5 (@ 3500 miles) into our church parking lot and turned right down the first row of cars. It was light out and the weather was pleasant. I turned right into a parking space with my foot on the brake. The car was facing and perpendicular to a sidewalk that was about 10 feet away.
2021 Mazda CX-5 · Service Brakes · filed with NHTSA Apr 27, 2022
I was parked at a fast food restaurant that had an outdoor kiosk for payment. I got out of my car to pay and got back in. After about a minute or two my car accelerated forward, going over a sloped curb and down a short low grade hill, hitting a pole. I was confused to how the car would go forward because I was in park the whole time

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-016-24b 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-016-24b 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-016-24b cover?
The manufacturer filed it against 62 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.
