Mazda bulletin SA-028-26
What it saysDESCRIPTION Some vehicles may exhibit a clicking, popping, tapping or knocking noise from the front when turning left or right and accelerating. NHTSA’s full summary ↓
Mazda filed this with NHTSA as a service bulletin dated Apr 17, 2026, received May 4, 2026, about the steering. It names 6 model years (2024–2026). 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 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.
DESCRIPTION Some vehicles may exhibit a clicking, popping, tapping or knocking noise from the front when turning left or right and accelerating. NOTE: The noise could occur at different steering wheel angles or power levels. Due to the insulating properties of the suspension and chassis, it can be difficult to determine which driveshaft is at fault by listening from inside the vehicle. See the attached video for an example of an outer CV joint clicking. Repair Procedure: Replace the affected driveshaft after confirming the source of the noise using chassis ears. Both driveshafts may be faulty; verify each side before replacement.

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 6 model years this bulletin names have filed 161 complaints with NHTSA since 2015. 7 of them name Suspension — 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.
Driver side and passenger side axle-area, making loud clicking and popping sounds on turns indicating major damage to CV joint, at around 10,000 miles. Primarily heard on sharply turned wheel acceleration. Two dealerships said they "couldn't reproduce the issue" even though I showed them the issue on recorded video.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mazda SA-028-26 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-028-26 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 SA-028-26 cover?
The manufacturer filed it against 6 model years: 2026 Mazda CX-30, 2025 Mazda CX-30, 2024 Mazda CX-30, 2026 Mazda CX-50, 2025 Mazda CX-50, 2024 Mazda CX-50. 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: built before 15 Nov 2025 — the build date is on the certification label in the driver’s door jamb.
