Hyundai filed this with NHTSA as a warranty extension dated Jun 25, 2026, received Jun 6, 2026, about the electrical system — 4 documents under this number: Z14 OL, 26-EV-004H DCS, 26-EV-004H DN, 26-EV-004H TSB. It names 7 model years (2022–2025).

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationPicked out of NHTSA’s summary below, word for word. The document itself is the record, and the dealer checks the VIN.
What 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.
Hyundai is extending the warranty coverage for the Integrated Charging Control Unit (ICCU) and ICCU fuse to 15 years/180,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners. Follow the flowchart in Technical Service Bulletin (TSB) 26-BE-010H to check for an active or stored occurrence of any Diagnostic Trouble Code (DTC) that requires replacement of the ICCU and replace the ICCU and ICCU fuse if necessary. Some vehicles may have an active DTC that requires ICCU replacement. Please note that any vehicles under 15 years/180,000 miles are covered by this TSB, even if vehicle is within High Voltage Warranty of 10 years/120,000 miles.

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 7 model years this bulletin names have filed 1,470 complaints with NHTSA since 2015. 1,374 of them name Electrical System, Fuel/Propulsion 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 car suddenly cut speed to 20mph while traveling at around 40mph. No matter how hard I pressed on the accelerator, it did not go over over 20mph. The dashboard also said speed limited to 20mph. I had to pull over on the side of the road. Turn off the ignition. Then turned it back on. Then the car resumed to operate as normal.

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai Z14 a recall?
No. A warranty extension 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 Z14 repair free?
A warranty extension 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 Z14 cover?
The manufacturer filed it against 7 model years: 2025 Hyundai Ioniq 5, 2024 Hyundai Ioniq 5, 2023 Hyundai Ioniq 5, 2022 Hyundai Ioniq 5, 2025 Hyundai Ioniq 6, 2024 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. The document itself sets the build window: built 4 Oct 2021 – 1 Nov 2024; built 9 Oct 2023 – 29 Oct 2024; built 14 Dec 2022 – 10 Oct 2024 — the build date is on the certification label in the driver’s door jamb.
