What it saysThis is a Technical Journal - If a customer experiences a "Propulsion System Service Required" message in the DIM, and the DTC IEM P0CBC62 is stored, please follow the advice under "Service". NHTSA’s full summary ↓
Volvo filed this with NHTSA as a service bulletin dated Nov 1, 2025, received Dec 22, 2025, about the fuel/propulsion system. It names 10 model years (2021–2026). 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.

Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches Volvo’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 9 model years this bulletin names have filed 219 complaints with NHTSA since 2015. 12 of them name Fuel/Propulsion 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.
I exclusively use one pedal drive (OPD) for my 2022 Volvo C40 EV. I have a log of about a dozen incidents in 2.5yrs where OPD has malfunctioned. Sometimes failing at speed, other times lurching quickly forward after stopping. I have contacted Volvo and they installed a flight data recorder.

Very frequently (4-5 times a week) the charging cable will not release from the vehicle. Pushing release button resolves to flashing yellow, red, or green lights, but does not release. Sometimes will release from console, but not always.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Volvo TJ37521.1.0-2025-10-14 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 TJ37521.1.0-2025-10-14 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 TJ37521.1.0-2025-10-14 cover?
The manufacturer filed it against 10 model years: 2024 Volvo C40, 2023 Volvo C40, 2022 Volvo C40, 2026 Volvo XC40, 2025 Volvo XC40, 2024 Volvo XC40 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
