Volvo service campaign S4343 022026
What it saysSC - Volvo Trucks has determined that a select group of trucks were built with an AHI Module fuel pressure sensor which does not meet our specifications. NHTSA’s full summary ↓
Volvo filed this with NHTSA as a service campaign dated Feb 1, 2026, received Mar 3, 2026, about the fuel/propulsion system. It names 8 model years (2024–2025). 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.
Model years it names
Source: as the manufacturer filed themAlso filed against: 2024 Volvo VAH; 2025 Volvo VAH; 2024 Volvo VHD; 2025 Volvo VHD; 2024 Volvo VN; 2025 Volvo VN; 2024 Volvo VNL (4); 2025 Volvo VNL (4).
None of these model years has a page on this site (it covers EPA-certified cars, trucks and SUVs from 2016), so the bulletin is listed here on its own.

A service campaign 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.
