Hyundai warranty extension LA18
Hyundai filed this with NHTSA as a warranty extension dated May 8, 2026, received May 12, 2026, about the electrical system — 1 document under this number: 26-01-043H 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai LA18 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 LA18 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 LA18 cover?
The manufacturer filed it against 1 model year: 2026 Hyundai Ioniq 5. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
