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.
This bulletin provides the information to inspect and add the Battery Conditioning function as necessary. Some late 2022MY vehicles may already have the function. The Battery Conditioning function optimizes the DC charging performance of the EV battery when the temperature of the battery is below 68°F (20°C). This function allows the EV battery to preheat prior to arriving at a DC charger site. Once software has been updated, it requires the owner of the vehicle to select a DC charger site as a POI (point of interest) in the vehicle’s navigation system to enable the battery conditioning heating when EV battery is below 68°F. Battery heating impact on DC charging will vary depending on the initial battery temperature and the estimated time to arrive at the POI. If it is possible to enable battery conditioning for longer time prior to departure, it can help to achieve the longer battery heating time needed at very low temperatures, but will temporarily reduce range. Enabling the battery conditioning will use battery power and temporarily reduce the driving range until charging.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 407 complaints with NHTSA since 2015. 85 of them name Power Train — 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.
Heard a "pop" sound and the car shortly after said "Check EV system." A few minutes later the car beeped loudly said "Stop vehicle and check power supply." A ODB scanner reported a P1A9096 code. This issue makes the vehicle inoperable with little warning

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai 23-01-017H-1 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 23-01-017H-1 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 23-01-017H-1 cover?
The manufacturer filed it against 1 model year: 2022 Hyundai Ioniq 5. 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 Oct 2021 — the build date is on the certification label in the driver’s door jamb.
