Common questions
Source: NHTSA, 49 CFR 579.5Is Karma 21.35.52.2 a recall?
No. A over-the-air update 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 21.35.52.2 repair free?
A over-the-air update 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 21.35.52.2 cover?
The manufacturer filed it against 7 model years: 2020 Karma Revero, 2021 Karma Revero GS-6, 2022 Karma Revero GS-6, 2021 Karma Revero GT, 2022 Karma Revero GT, 2021 Karma Revero GTS and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
