Livewire warranty extension M1555
Livewire filed this with NHTSA as a warranty extension dated Mar 1, 2025, received Nov 7, 2024, about the electrical system — 2 documents under this number. It names 8 model years (2020–2024). 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.

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 Livewire M1555 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.
Is the M1555 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 M1555 cover?
The manufacturer filed it against 8 model years: 2020 Livewire Livewire, 2021 Livewire Livewire ONE, 2022 Livewire Livewire ONE, 2023 Livewire Livewire ONE, 2024 Livewire Livewire ONE, 2023 Livewire S2 DEL MAR and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
