Volvo bulletin M0308 202411
Volvo filed this with NHTSA as a emissions communication dated Nov 14, 2024, received Nov 27, 2024, about the engine. It names 9 model years (2017–2019). A emissions communication 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.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationVolvo Trucks has identified that the Selective Catalyst Reduction (SCR) system in certain vehicles equipped with the MY 2017 or 2018 (13L VGT) engine are not meeting California and EPA emissions standards, or Volvo cannot confirm its compliance. These vehicles have been flagged due to telematics data showing that the NOx conversion efficiency of the SCR system has dropped below 94% for eight weeks. Alternatively, these vehicles may have communication issues with telematics, such as not reporting or ceasing reporting for the same period.

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.
