Mercedes-Benz service campaign NCU - 2025080001

Mercedes-Benz filed this with NHTSA as a service campaign dated Aug 15, 2025, received Aug 25, 2025, about the electrical system. It names 5 model years (2022–2024). 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.
