Mazda bulletin SA-035-23
What it saysSome customers may complain of a lack of power under heavy load without any warning lights or DTCs. NHTSA’s full summary ↓
Mazda filed this with NHTSA as a service bulletin dated Jun 1, 2023, received Jul 5, 2023, about the engine. It names 36 model years (2016–2023). 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 customers may complain of a lack of power under heavy load without any warning lights or DTCs. This concern may be due to a loose or detached hood weatherstrip, which can cause a blockage or restriction in the air intake system.

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 33 model years this bulletin names have filed 2,756 complaints with NHTSA since 2015. 781 of them name Engine — 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 2018 Mazda CX-5, the 29 owners who gave an odometer reading for Engine reported it at a median of 28,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Fails to accelerate and change gears. This has been happening since we purchased the vehicle. It has been back to the dealership multiple time and has not been resolved.

2016 Mazda CX-9 · Engine · filed with NHTSA Jul 22, 2019 · ODI 11233883
The engine on my 2022 naturally aspirated Mazda CX5, is making a loud ticking noise when cold started. The vehicle is in pristine condition and is services regularly at the dealer with only 33,000 miles. The ticking noise is a known issue for this make and model, where Mazda has issued a TSB for faulty hydraulic valve lash.

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-035-23 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 SA-035-23 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 SA-035-23 cover?
The manufacturer filed it against 36 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.
