Volvo bulletin 37813.2.0
Volvo filed this with NHTSA as a service bulletin dated May 20, 2026, received May 14, 2026, about the unknown or other — 2 documents under this number. It names 39 model years (2017–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

Common questions
Source: NHTSA, 49 CFR 579.5Is Volvo 37813.2.0 a recall?
No. A service bulletin 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, or on its page here.
Is the 37813.2.0 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.

The manufacturer filed it against 39 model years: 2024 Volvo C40, 2023 Volvo C40, 2022 Volvo C40, 2026 Volvo EC40, 2025 Volvo EC40, 2025 Volvo S60 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
