Hyundai filed this with NHTSA as a service bulletin dated Sep 18, 2023, received Oct 2, 2023, about the electrical system. It names 13 model years (2021–2024). 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.

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 2,801 complaints with NHTSA since 2015. 1,595 of them name Electrical System, 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 2022 Hyundai Tucson, the 21 owners who gave an odometer reading for Engine reported it at a median of 29,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The vehicle is currently at the dealership. I purchased the 2022 hyundai Tucson hybrid limited in April. Have gotten my oil changes done religiously at the dealership. Vehicle is at 22k miles. And had oil change 5 days prior to incident. I was on the way to work and vehicle started to struggle to accelerate, engine began malfunctioning.
2022 Hyundai Tucson · Engine · filed with NHTSA Feb 3, 2023 · ODI 11505484
What component or system failed or malfunctioned: Rear electric motor. Specifically the "engine oil pump" that is used to cool the rear motor. The pump does not respond to MCU commands and does not cool the motor. This causes the motor to overheat after about an hour of highway driving causing the motor to provide VERY limited power.

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 Hyundai 23-EE-010H 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 23-EE-010H 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 23-EE-010H cover?
The manufacturer filed it against 13 model years: 2023 Hyundai Elantra, 2022 Hyundai Elantra, 2021 Hyundai Elantra, 2023 Hyundai Ioniq 5, 2022 Hyundai Ioniq 5, 2023 Hyundai Ioniq 6 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
