Hyundai filed this with NHTSA as a service campaign dated Sep 18, 2024, received Aug 7, 2024, about the electrical system — 2 documents under this number: 24-01-051H-1, 24-01-051H. It names 6 model years (2022–2024). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

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.
Certain 2022-2024MY IONIQ 5 (NE1), 2023-2024MY IONIQ 6 (CE1) and 2024-2025MY Kona Electric (SX2 EV) vehicles may exhibit a condition while charging with a 240V AC (Level 2) charger where the vehicle experiences an interrupted charging session or a lower charging speed. This occurs to prevent potential damage to the charging cable connection. Follow the procedure in this TSB to update the software logic for the Vehicle Charging Management System (VCMS), which initiates a self-restart that allows the vehicle charging to return to full capacity once stabilized.

Read by machine from the document NHTSA serves (6 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.
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 6 model years this bulletin names have filed 1,183 complaints with NHTSA since 2015. 866 of them name Electrical System — 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 Ioniq 5, the 20 owners who gave an odometer reading for Electrical System reported it at a median of 22,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2022 Hyundai Ioniq 5. The contact stated while driving 59 MPH, a warning message advising to stop the vehicle due to low battery was displayed; however, the main battery was fully charged. The instrument panel lights turned off and the vehicle decelerated to 23 MPH. The contact veered to the right lane.

2023 Hyundai Ioniq 6 · Electrical System · filed with NHTSA Jul 12, 2025 · ODI 11672992
After several days of below freezing temps, started car after work and received "check electrical systems" warning. Couldn't drive above 15-25 mph. Eventually led to total shutdown, could not start, lock/unlock doors, etc. Had to tow to dealer which they eventually deemed the ICCU to be at fault.

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 SERVICE CAMPAIGN 9B5 a recall?
No. A service campaign 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 SERVICE CAMPAIGN 9B5 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does SERVICE CAMPAIGN 9B5 cover?
The manufacturer filed it against 6 model years: 2024 Hyundai Ioniq 5, 2023 Hyundai Ioniq 5, 2022 Hyundai Ioniq 5, 2024 Hyundai Ioniq 6, 2023 Hyundai Ioniq 6, 2024 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 4 Oct 2023 – 18 Dec 2023; built 14 Dec 2022 – 25 Dec 2023; built 5 Oct 2023 – 13 Jul 2024 — the build date is on the certification label in the driver’s door jamb.
