Zero service campaign SV-RCL-025-021
What it saysInitial notice to dealers of the upcoming recall (25V-834). NHTSA’s full summary ↓
Zero filed this with NHTSA as a service campaign dated Dec 20, 2025, received Jan 7, 2026, about the fuel/propulsion system — 2 documents under this number. It names 9 model years (2023–2024). 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.

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.
Model years it names

None of these model years has a page on this site (it covers EPA-certified cars, trucks and SUVs from 2016), so the bulletin is listed here on its own.

Common questions
Source: NHTSA, 49 CFR 579.5Is Zero SV-RCL-025-021 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.
Is the SV-RCL-025-021 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 SV-RCL-025-021 cover?
The manufacturer filed it against 9 model years: 2024 Zero DSR, 2023 Zero Dsr/x, 2024 Zero Dsr/x, 2023 Zero SR, 2024 Zero SR, 2023 Zero Sr/f and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
