Hyundai warranty extension LA13
Hyundai filed this with NHTSA as a warranty extension dated Aug 11, 2026, received Mar 4, 2026, about the engine — 4 documents under this number: 26-01-026H-1 WebDCS, 26-01-026H-1 TSB, 26-01-026H DCS, 26-01-026H TSB. It names 1 model year (2026). A warranty extension 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 communicationCertain Palisade (LX3) and Palisade Hybrid (LX3 HEV) vehicles may exhibit a “Check Active Air Flap System" warning message, Engine MIL ON, and/or “Low Engine Oil" warning message, due to improper operation of the Active Air Flap (AAF) system. DTCs include, but are not limited to: P05AE00, P05B100, P05B200 P05B400, P05FE00, P15A200, P15A500, P2C7400, U028500, U028B00, and/or U100800. This condition may be caused by water ingress and corrosion at the wiring connections for the lower AAF actuators and/or sensors. This Technical Service Bulletin (TSB) 26-01-026H contains instructions to inspect the front bumper wiring connectors, AAF actuators, and sensors for water ingress and corrosion, and to replace them if necessary.

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 LA13 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 LA13 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 LA13 cover?
The manufacturer filed it against 1 model year: 2026 Hyundai Palisade. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
