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 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.

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. The document itself sets the build window: 2026MY Palisade (LX3): built 7 May 2025 – 16 Jun 2026 — the build date is on the certification label in the driver’s door jamb.
