Hyundai filed this with NHTSA as a service campaign dated Feb 24, 2026, received Mar 4, 2026, about the engine — 2 documents under this number: 26-01-021H DCS, 26-01-021H TSB. It names 1 model year (2026). A service campaign 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 owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 136 complaints with NHTSA since 2015. 17 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.
I am reporting a safety concern involving my 2026 Hyundai Palisade Limited involving repeated engine malfunction warning lights and diagnostic trouble code P001600 (camshaft/crankshaft timing correlation fault).

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai LA16 a recall?
No. A service campaign 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 LA16 repair free?
A service campaign 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 LA16 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: built 11 Aug 2025 – 30 Sep 2025 — the build date is on the certification label in the driver’s door jamb.
