What it saysInstall of recommended 12Volt battery maintainer NHTSA’s full summary ↓
Karma filed this with NHTSA as a service bulletin dated Oct 30, 2025, received Nov 4, 2025, about the electrical system. It names 12 model years (2019–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

Common questions
Source: NHTSA, 49 CFR 579.5Is Karma SC-25-90-02 a recall?
No. A service bulletin 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 SC-25-90-02 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SC-25-90-02 cover?
The manufacturer filed it against 12 model years: 2020 Karma Revero, 2019 Karma Revero, 2021 Karma Revero, 2022 Karma Revero, 2025 Karma Revero, 2026 Karma Revero and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
