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.
Some Palisade (LX2) vehicles may exhibit engine oil leakage at the engine oil filter housing assembly due to deterioration of the housing seal. Hyundai is extending the warranty coverage for the engine oil filter housing seal 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 procedure in Technical Service Bulletin (TSB) 26-EM-012H to replace the engine oil filter housing seal in order to address this condition. Please note that any vehicles within 15 years / 180,000 miles are covered by this TSB, even if the vehicle is still within the New Vehicle Limited Warranty (NVLW) of 5 years / 60,000 miles or Powertrain Warranty of 10 years / 100,000 miles (for the original owner).

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 2,373 complaints with NHTSA since 2015. 259 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.
On the 2020 Hyundai Palisade, the 15 owners who gave an odometer reading for Engine reported it at a median of 25,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The engie restarted itself after being shut off and no key was near vehicle and continued to run overnight, filing car with carbon monoxide. Hyundai service department was contacted and said no inspection was need but to monitor car and contact Hyundai customer line and advise. The reference case number is 20244323

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai Z15 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 Z15 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 Z15 cover?
The manufacturer filed it against 6 model years: 2025 Hyundai Palisade, 2024 Hyundai Palisade, 2023 Hyundai Palisade, 2022 Hyundai Palisade, 2021 Hyundai Palisade, 2020 Hyundai Palisade. 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 10 Apr 2019 – 10 Jun 2025 — the build date is on the certification label in the driver’s door jamb.
