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.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 47 complaints with NHTSA since 2015. 11 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.
I am reporting a potential safety-related defect in my 2025 Mazda CX-50 Preferred, which is approximately four months old. On one occasion, the vehicle moved backward while in Drive mode. This occurred twice on the same day under similar conditions on a slight incline.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda PF-24-11 a recall?
No. A manufacturer communication 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 PF-24-11 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 PF-24-11 cover?
The manufacturer filed it against 1 model year: 2025 Mazda CX-50. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
