Volvo bulletin TJ37279.4.0-2025-11-06

What it saysThis is a Technical Journal: In most cases the VCU does not need to be replaced. *The script in VIDA for VCU reload is now working NHTSA’s full summary ↓

Volvo filed this with NHTSA as a service bulletin dated Nov 14, 2025, received Dec 22, 2025, about the electrical system. It names 2 model years (2025–2026). 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.

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 database

Owners of the 2 model years this bulletin names have filed 81 complaints with NHTSA since 2015. 43 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.

While driving my nearly new 2026 Volvo EX90 at freeway speed, the vehicle unexpectedly began sounding warning tones and experienced a significant loss of propulsion/power. The vehicle was unable to maintain normal acceleration and freeway performance, creating a serious safety risk while I was traveling in active freeway traffic.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Volvo TJ37279.4.0-2025-11-06 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 TJ37279.4.0-2025-11-06 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 TJ37279.4.0-2025-11-06 cover?

The manufacturer filed it against 2 model years: 2026 Volvo EX90, 2025 Volvo EX90. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
