Motiv bulletin 3.4.0.A
Motiv filed this with NHTSA as a over-the-air update dated Oct 1, 2025, received Oct 30, 2025, about the fuel/propulsion system — 1 document under this number: TSB-2025-0004. It names 41 model years (2019–2025). 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.

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.
