Volvo service campaign S0302 202408
What it saysVolvo trucks has determined that certain VN and VHD model trucks built with TGW3 have stopped communicating after production. NHTSA’s full summary ↓
Volvo filed this with NHTSA as a service campaign dated Aug 28, 2024, received Sep 4, 2024, about the electrical system. It names 12 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.
