Volvo bulletin M0039 032026
What it saysEmissions _ EC0039 MST21 Failure to Detect P20EE. NHTSA’s full summary ↓
Volvo filed this with NHTSA as an emissions communication dated Mar 3, 2026, received Apr 2, 2026, about the electrical system. It names 2 model years (2020–2021). An 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.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Volvo M0039 032026 a recall?
No. A emissions communication is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls.
Is the M0039 032026 repair free?
A emissions communication 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.
Which vehicles does M0039 032026 cover?
The manufacturer filed it against 2 model years: 2020 Volvo VN, 2021 Volvo VN. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built on or after 20 Jul 2017 — the build date is on the certification label in the driver’s door jamb.
