Karma filed this with NHTSA as a over-the-air update dated Mar 6, 2025, about the unknown or other — 1 document under this number: TB-25-94-01. It names 7 model years (2020–2022). A over-the-air update 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.

Quote the number at a service desk; it is what the dealer’s system is keyed on.
