It names 5 model years (2020–2024).

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationCertain Palisade (LX2) vehicles may exhibit a clunking or thumping noise from the rear of the vehicle while driving over rough roads. This may be caused by worn self-leveling rear shock absorbers. Hyundai is extending the warranty coverage for the self-leveling rear shock absorbers to 10 years/120,000 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-SS-001H to identify the source of the noise, and if necessary, replace one or both self-leveling rear shock absorbers. Please note that for the first repair, replacement of both rear shock absorbers will be covered by this warranty extension. For subsequent repairs, one or both rear shock absorbers will be covered depending upon the impacted side(s). Please note that any vehicles under 10 years/120,000 miles are covered by this TSB, even if vehicle is within 5 years/60,000 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai Z12 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 Z12 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 Z12 cover?
The manufacturer filed it against 5 model years: 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.
