What it saysSome vehicles may have the check engine light on with DTC P0524:00 or P055F:00 stored in memory. NHTSA’s full summary ↓
Mazda filed this with NHTSA as a service bulletin dated May 24, 2024, about the engine. It names 13 model years (2018–2021). 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.
Some vehicles may have the check engine light on with DTC P0524:00 or P055F:00 stored in memory. Contamination in the engine oil may cause the engine oil solenoid valve to become stuck, resulting in improper operation of the oil pump and improper oil pressure.
Trouble codes it names: P0524 P055F

Read by machine from the document NHTSA serves (5 pages), read Sep 30, 2026. A part number is shown only where it matches Mazda’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 13 model years this bulletin names have filed 1,249 complaints with NHTSA since 2015. 547 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.
Low Engine Oil Light keeps appearing at seemingly random intervals. I will heat up my vehicle, begin driving, and sometimes after 10 minutes, sometimes after 20 minutes it will come on. I drove 2.5 hours and it did not come on at all. It first started Friday 11/29 and was driven to and from a few places and came on 50% of the time.
2020 Mazda CX-30 · Engine · filed with NHTSA Dec 3, 2024
For some reason this vehicle will make a whoop sound after driving it for a little then idle, either at a stop light or sitting in a parking lot. The first time we heard it we thought that there was a police vehicle in the area. We took it to Mazda dealership, and they didn't what why it was making that sound.
2020 Mazda CX-5 · Engine · filed with NHTSA Jun 19, 2022
Vehicle went into limp mode while passing on two lane road. Cause was determined to be wrong logic in PCM for cylinder deactivation. This worng logic caused low oil pressure in the lifter during deactivation which in turn caused the rocker arm to become dislodged rendering the associated valve inoperable.
2018 Mazda CX-5 · Engine · filed with NHTSA May 6, 2019
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 01-003-24 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 01-003-24 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 01-003-24 cover?
The manufacturer filed it against 13 model years: 2021 Mazda CX-30, 2020 Mazda CX-30, 2021 Mazda CX-5, 2020 Mazda CX-5, 2019 Mazda CX-5, 2018 Mazda CX-5 and more. 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 24 Aug 2020; built before 14 Dec 2020; built before 23 Dec 2020 — the build date is on the certification label in the driver’s door jamb.
