Hyundai filed this with NHTSA as a service bulletin dated Aug 28, 2024, received Sep 4, 2024, about the engine. It names 1 model year (2022). 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.

Read by machine from the document NHTSA serves (7 pages), read Sep 30, 2026. A part number is shown only where it matches Hyundai’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.

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 1 model year this bulletin names have filed 130 complaints with NHTSA since 2015. 38 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.
While driving on the interstate, the car went into limp mode (does not rev above 2000 rpm). I was unable to maintain speed or merge back into interstate. The dealership has inspected the vehicle, however, they confirm everything is normal. The car did give an engine error code of P132600 for Powertrain.

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai 24-EM-005H 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 24-EM-005H 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 Hyundai warranty extension on file lists the ones Hyundai has filed.
Which vehicles does 24-EM-005H cover?
The manufacturer filed it against 1 model year: 2022 Hyundai Kona. 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 2 Mar 2021 – 15 Apr 2022 — the build date is on the certification label in the driver’s door jamb.
