GMC service campaign N242454441 -03
GMC filed this with NHTSA as a service campaign dated Oct 9, 2025, about the power train. It names 11 model years (2020–2022). 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.
