Volvo filed this with NHTSA as a service bulletin dated Jun 12, 2024, received Aug 21, 2024, about the electrical system. It names 5 model years (2021–2024). 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.

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 155 complaints with NHTSA since 2015. 34 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.

It happens when I am backing up very slowly. It throws me forward and then thrusts me back into the headrest.

Common questions
Source: NHTSA, 49 CFR 579.5Is Volvo TJ36309.10.0-2024-06-06 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 TJ36309.10.0-2024-06-06 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.
Which vehicles does TJ36309.10.0-2024-06-06 cover?
The manufacturer filed it against 5 model years: 2024 Volvo C40, 2022 Volvo C40, 2023 Volvo XC40, 2022 Volvo XC40, 2021 Volvo XC40. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
